New astronomical simulations suggest that Earth-like planets may be far more common than previously thought. By allowing planets to form from randomized starting conditions, researchers found that worlds resembling Earth, Venus, and Mars can naturally emerge around other stars. The findings offer new clues about how habitable planets form—and how common life-friendly environments might be across the universe.

[0:03] Speaker 1: Welcome to Bedtime Astronomy. Explore the wonders of the cosmos
[0:07] Speaker 1: with our soothing Bedtime Astronomie podcast. Each episode offers a
[0:12] Speaker 1: gentle journey through the stars, planets, and beyond, perfect for
[0:16] Speaker 1: unwinding after a long day. Let's travel through the mysteries
[0:20] Speaker 1: of the universe as you drift off into a peaceful
[0:22] Speaker 1: slumber under the night sky.
[0:27] Speaker 2: Okay, so imagine you walk into this massive, just cavernous casino. Okay,
[0:32] Speaker 2: it's loud, it's chaotic, and right in the middle of
[0:35] Speaker 2: the floor you find this slot machine that looks like
[0:39] Speaker 2: it was just thrown together out of literal scrap metal.
[0:42] Speaker 3: Oh, I can picture it.
[0:43] Speaker 2: Yeah, the gears are mismatched, the wiring is a complete
[0:46] Speaker 2: rat's nest, and it's totally randomized, and you just kind
[0:49] Speaker 2: of shrug. You put in a single coin, pull this
[0:52] Speaker 2: rusty lever, and immediately bells go off.
[0:55] Speaker 3: You hit the jackpot exactly, You.
[0:57] Speaker 2: Hit the grand jackpot on the very first try and
[0:59] Speaker 2: first centuries. I mean, that is essentially how humanity has
[1:02] Speaker 2: viewed our existence on Earth. Right, we look around at
[1:05] Speaker 2: our liquid oceans and our you know, perfectly balanced carbon cycle,
[1:09] Speaker 2: are incredibly lucky distance from the Sun, and the prevailing
[1:12] Speaker 2: thought is just, wow, we are a one in a
[1:14] Speaker 2: billion cosmic accident.
[1:17] Speaker 3: It is a it's a profoundly comforting thought. In a
[1:20] Speaker 3: strange way. We've historically treated our own existence as this
[1:24] Speaker 3: miraculous sort of freak anomaly. The rare Earth hypothesis has
[1:28] Speaker 3: dominated a lot of astronomical thinking for a long time.
[1:32] Speaker 3: We like being the lucky winners of the universe totally.
[1:34] Speaker 3: It makes us feel undeniably special, it does.
[1:37] Speaker 2: And let's, you know, let's unpack that feeling of being
[1:39] Speaker 2: special today because everything we thought we knew about that
[1:42] Speaker 2: cosmic jackpot is well, it's currently being flipped completely upside down.
[1:46] Speaker 3: It really is.
[1:47] Speaker 2: We are looking at this monumental shift in how we
[1:50] Speaker 2: understand the formation of our Solar system, and this is
[1:53] Speaker 2: all spearheaded by the recent breakthrough is presented at the
[1:57] Speaker 2: Origins twenty twenty six conference in Paris, right, Harris, Yeah,
[2:01] Speaker 2: particularly the work of planetary scientist Nator Hahypur out of
[2:05] Speaker 2: the University of Hawaii. So the central question we are
[2:08] Speaker 2: tackling today is just massive, huge. Was the formation of
[2:12] Speaker 2: our world, you know, a habitable, rocky planet at this
[2:16] Speaker 2: exact location a bizarre fluke of nature or was it
[2:19] Speaker 2: an absolutely inevitable consequence of physics?
[2:22] Speaker 3: And to really answer that, we have to kind of
[2:23] Speaker 3: strip away the philosophical romanticism. We have to transition entirely
[2:27] Speaker 3: away from human assumptions and look purely at the hard
[2:30] Speaker 3: physics of stellar nurseries. Just the math, exactly, just the math.
[2:34] Speaker 3: And the short answer, which is, honestly, it's going to
[2:37] Speaker 3: completely alter how we look at the night sky. Is
[2:40] Speaker 3: that a planet like Earth is an entirely expected.
[2:43] Speaker 2: Outcome, wait, really expected.
[2:45] Speaker 3: Completely expected. It is standard operating procedure for a solar
[2:49] Speaker 3: system like ours.
[2:50] Speaker 2: Which is just a mind bending paradigm shift. I mean,
[2:53] Speaker 2: we are so thoroughly conditioned by the narrative of the
[2:58] Speaker 2: Goldilock zone being this credibly rare, delicate, precarious balance, you know,
[3:03] Speaker 2: absolutely the idea that you could just let the universe
[3:06] Speaker 2: run its course and an Earth naturally pops out feels,
[3:09] Speaker 2: I don't know, it feels almost like heresy.
[3:10] Speaker 3: Yeah, it goes against everything we were taught in grade school.
[3:13] Speaker 2: Right, But before we get into high pores, groundbreaking new
[3:16] Speaker 2: models that you know, prove Earth as a standard product
[3:19] Speaker 2: of the universe. I really want to understand how we
[3:22] Speaker 2: got the science so wrong for so long.
[3:25] Speaker 3: That's a great place to start, Like.
[3:26] Speaker 2: Why were we so convinced that we were this impossible
[3:30] Speaker 2: statistical anomaly.
[3:31] Speaker 3: Well, it ultimately comes down to the severe limitations of
[3:35] Speaker 3: how planetary science has been modeled for the last three decades. Okay, Historically,
[3:40] Speaker 3: when astrophysicists tried to simulate how terrestrial planets formed, they
[3:45] Speaker 3: were operating in a highly restricted, highly specific environment.
[3:49] Speaker 2: I mean, how does one even begin to model the
[3:52] Speaker 2: birth of a solar system.
[3:54] Speaker 3: It's incredibly difficult.
[3:55] Speaker 2: It's not like you can put a bunch of space
[3:57] Speaker 2: dust in a vacuum and a giant centrifuge and university
[4:00] Speaker 2: lab and it's beIN right.
[4:02] Speaker 3: No, you can't do that at all. You have to
[4:04] Speaker 3: rely entirely on computer simulations. Okay, specifically what we call
[4:08] Speaker 3: n body simulating body. Yeah, n body. These algorithms try
[4:12] Speaker 3: to track the gravitational interactions of multiple celestial bodies over
[4:16] Speaker 3: millions of years.
[4:18] Speaker 2: Millions of years, wow, exactly.
[4:20] Speaker 3: But for the past thirty years, the computational power just
[4:22] Speaker 3: wasn't there to do it organically. Oh, I see, the
[4:25] Speaker 3: simulations were by necessity fairly crude representations of physics, right, just.
[4:29] Speaker 2: Because of the era they were working in, exactly.
[4:32] Speaker 3: And the researchers working on them recently realized they had
[4:35] Speaker 3: hit an immovable wall.
[4:37] Speaker 2: They couldn't go any further, right, The.
[4:39] Speaker 3: Old modeling techniques had these severe limitations, and they simply
[4:43] Speaker 3: couldn't be pushed any further to yield any new insights.
[4:46] Speaker 2: I was trying to visualize this process earlier, and tell
[4:50] Speaker 2: me if this analogy holds up.
[4:52] Speaker 3: That's here.
[4:53] Speaker 2: It feels like the last thirty years of modeling was
[4:55] Speaker 2: essentially like trying to bake a cake. But you start
[4:59] Speaker 2: the whole process by staring at a high definition photograph
[5:02] Speaker 2: of a beautifully frosted, finished slice of cake, right, okay,
[5:06] Speaker 2: And you measure your ingredients, and you constantly adjust your
[5:10] Speaker 2: oven temperature specifically to force your batter to look exactly
[5:14] Speaker 2: like that photograph. Yes, rather than just putting standard raw
[5:18] Speaker 2: ingredients in the oven, turning it on and seeing what
[5:20] Speaker 2: naturally bakes. I mean, we're scientists fundamentally cheating by accommodating
[5:24] Speaker 2: what they already knew about the architecture of our solar system.
[5:27] Speaker 3: That is a brilliant way to conceptualize it.
[5:29] Speaker 2: Actually, yeah, yeah.
[5:30] Speaker 3: In the scientific community, we refer to this as teleological thinking.
[5:34] Speaker 2: Teleological thinking of basically.
[5:36] Speaker 3: Assuming the end goal from the very beginning and letting
[5:39] Speaker 3: that dictate your process.
[5:40] Speaker 2: Right, right, These computer simulations were inherently flawed because they
[5:45] Speaker 2: assumed a specific planetary architecture as the required finish line.
[5:50] Speaker 3: Because they live here, they know what it looks like exactly.
[5:53] Speaker 2: They knew Earth was sitting here at one astronomical unit
[5:56] Speaker 2: or one AU. They knew Venus was closer to the Sun,
[6:00] Speaker 2: they knew Mars was further out. So when they set
[6:03] Speaker 2: up the simulation, they tweaked the initial conditions of the
[6:07] Speaker 2: simulated space dust.
[6:09] Speaker 3: They meddled with it.
[6:10] Speaker 2: They totally meddled with it. They adjusted the gravitational algorithms,
[6:14] Speaker 2: They effectively massaged the math to ensure the simulation ended
[6:18] Speaker 2: up looking exactly like our solar system.
[6:20] Speaker 3: But I mean, doesn't that totally defeat the purpose of
[6:23] Speaker 3: running an experiment in the first place.
[6:25] Speaker 2: It does.
[6:26] Speaker 3: If you engineer the starting line to guarantee the finish line,
[6:29] Speaker 3: you haven't actually learned anything about how a solar system
[6:32] Speaker 3: forms in the wild, right, You've just proven that your
[6:35] Speaker 3: computer program works.
[6:36] Speaker 2: It creates a massive blind spot. Yes, But to be
[6:39] Speaker 2: fair to the scientists of the nineteen nineties and two thousands,
[6:41] Speaker 2: they didn't really have a choice.
[6:42] Speaker 3: Oh because the computers exactly if they didn't apply those constraints,
[6:47] Speaker 3: the computing power of the era couldn't handle the sheer
[6:50] Speaker 3: chaos of the calculations. Oh, okay, the end body problem.
[6:55] Speaker 3: Calculating the gravitational effect of thousands of moving objects on
[6:59] Speaker 3: one another. It causes errors to compound incredibly fast in
[7:03] Speaker 3: a computer.
[7:04] Speaker 2: Model like it just spirals out of control.
[7:06] Speaker 3: Starrel's completely out of control. So they had to build
[7:08] Speaker 3: guide rails.
[7:09] Speaker 2: Right.
[7:10] Speaker 3: But true science, particularly when you're dealing with astrophysics and
[7:14] Speaker 3: the chaotic origins of stellar systems, it requires completely removing
[7:19] Speaker 3: human assumptions just letting it run. You have to set
[7:22] Speaker 3: up the raw physical laws, start the clock, and see
[7:25] Speaker 3: if the outcome occurs naturally, because if you constantly force
[7:28] Speaker 3: the simulation to build an Earth, you can never know
[7:30] Speaker 3: if Earth would have built itself.
[7:32] Speaker 2: That makes a lot of sense, but I imagine that must
[7:34] Speaker 2: have been incredibly frustrating for the researchers who spent thirty years,
[7:37] Speaker 2: you know, running headfirst into that methodological wall.
[7:41] Speaker 3: Oh, incredibly frustrating.
[7:42] Speaker 2: You know there is a deeper truth, but your tools
[7:44] Speaker 2: are forcing you to just paint by numbers. So how
[7:47] Speaker 2: do we break out of that? How do we stop
[7:49] Speaker 2: baking from the photograph?
[7:50] Speaker 3: Well, we have to throw out the blueprint entirely, okay,
[7:52] Speaker 3: And that is exactly what brings us to the Origins
[7:54] Speaker 3: twenty twenty six conference, right nater hanka Port and his
[7:58] Speaker 3: colleagues spearheaded a completely revolutionary approach to this problem.
[8:02] Speaker 2: So what did they do?
[8:03] Speaker 3: They decided to strip away every single assumption and start
[8:07] Speaker 3: from absolute zero.
[8:09] Speaker 2: I want to set the stage here carefully because the
[8:11] Speaker 2: details matter. What Didhi Hypor's team actually do differently in
[8:16] Speaker 2: their modeling, because it sounds like they just decided to
[8:18] Speaker 2: break all the established rules of planetary modeling.
[8:21] Speaker 3: They absolutely did. Instead of assuming an end goal and
[8:24] Speaker 3: working backward, they went to the absolute starting line, which
[8:27] Speaker 3: is what the protoplanetary disc.
[8:30] Speaker 2: Okay, for someone who might be a little rusty on
[8:32] Speaker 2: their astrophysics, what exactly does a protoplanetary disc look like?
[8:36] Speaker 3: So picture a young, newly formed star that just ignited, okay,
[8:40] Speaker 3: got it? Surrounding it is this massive rotating, flattened cloud.
[8:45] Speaker 3: It's a circumstellar disc made of dense gas, microscopic silicon, dust,
[8:51] Speaker 3: and ice. It looks a bit like a glowing, incredibly
[8:54] Speaker 3: messy pancake spinning around a light bulb.
[8:56] Speaker 2: A messy pancake. I like that.
[8:58] Speaker 3: Yeah, it's the stellar nursery. But here is the critical
[9:02] Speaker 3: difference in Highpores methodology. Past models usually assumed this disc
[9:07] Speaker 3: was relatively smooth and evenly distributed.
[9:10] Speaker 2: Right, perfectly balanced, exactly.
[9:12] Speaker 3: But Hi Hypores team assumed a completely non uniform distribution
[9:16] Speaker 3: of solid material.
[9:18] Speaker 2: Meaning the space dust and the early rocks weren't perfectly
[9:21] Speaker 2: mathematically spread out like a a neatly raked zen garden.
[9:25] Speaker 3: Not at all. Space is violent and messy. Yeah. You
[9:28] Speaker 3: have supernova shockwaves passing through. You have magnetic turbulence, oh wow. Yeah,
[9:33] Speaker 3: you have areas where gas drag slows down dust particles
[9:36] Speaker 3: and makes them clump up unpredictably. It's chunky, very chunky. Yeah.
[9:39] Speaker 3: So the team embraced what they called a random start. Okay,
[9:42] Speaker 3: they took planetesimos, which are essentially cosmic boulders and larger
[9:46] Speaker 3: planetary embryos, and they scattered them throughout this simulated disc
[9:51] Speaker 3: with total mathematical randomness, just wherever wherever, no guide rails,
[9:56] Speaker 3: no fine tuning to make it look like our solar.
[9:58] Speaker 2: System, and then they just hit play on the simulation.
[10:00] Speaker 3: They have play over one thousand times.
[10:03] Speaker 2: One thousand times.
[10:05] Speaker 3: Yeah, they ran more than one thousand distinct simulations of
[10:09] Speaker 3: the late stage of terrestrial planet formation.
[10:11] Speaker 2: Wow.
[10:12] Speaker 3: And the key is that they took their hands completely
[10:15] Speaker 3: off the steering wheel.
[10:16] Speaker 2: They just let it go.
[10:17] Speaker 3: They let the pure, unadulterated physics of planet formation take
[10:21] Speaker 3: over entirely with zero tweaking to try and recreate our
[10:25] Speaker 3: current solar neighborhood.
[10:26] Speaker 2: I have to jump in on the sheer scale of that,
[10:29] Speaker 2: because there is a practical computational side to this that
[10:32] Speaker 2: I just find fascinating.
[10:33] Speaker 3: The tech side is wild.
[10:34] Speaker 2: We talked about how earlier scientists had to cheat because
[10:37] Speaker 2: of computer limits. Running one thousand complex n body physics
[10:41] Speaker 2: simulations of an entire solar system forming over millions of years.
[10:46] Speaker 2: I would assume that requires a supercomputer the size of
[10:48] Speaker 2: a warehouse running constantly for a decade.
[10:51] Speaker 3: Well, that used to be the reality, right previously, running
[10:55] Speaker 3: just a single one of these types of high fidelity
[10:58] Speaker 3: orbital mechanics simulations would take six to eight months of
[11:01] Speaker 3: continuous computing time on a very powerful machine.
[11:05] Speaker 2: Six to eight months for one run.
[11:07] Speaker 3: For one run.
[11:07] Speaker 2: Oh my gosh.
[11:08] Speaker 3: But we've seen a massive technological leap recently, and it's
[11:12] Speaker 3: not just about processors getting faster. What is it? Then?
[11:16] Speaker 3: It's about the optimization of the physics engines themselves.
[11:19] Speaker 2: What do you mean by optimization like smarter math?
[11:21] Speaker 3: Exactly that. Smarter math researchers developed what are called simplectic.
[11:25] Speaker 2: Integrators, simplectic integrators.
[11:28] Speaker 3: Yes, it's a type of numerical algorithm specifically designed to
[11:31] Speaker 3: solve the equations of classical mechanics while perfectly conserving things
[11:35] Speaker 3: like energy and momentum over massive time scales.
[11:38] Speaker 2: Ah, so it doesn't lose track of the details.
[11:40] Speaker 3: Right, Because the math is vastly more efficient at handling
[11:43] Speaker 3: the chaotic gravitational pull of thousands of objects, these complex
[11:47] Speaker 3: simulations can now be completed in just six to eight
[11:50] Speaker 3: weeks wait, down from eight months, down from eight months
[11:53] Speaker 3: to just weeks.
[11:54] Speaker 2: That is a staggering increase in efficiency.
[11:57] Speaker 3: And it gets better. They aren't relying on giant liquid
[12:01] Speaker 3: cooled supercomputers to do it anymore. No, No, they are
[12:04] Speaker 3: running these optimized algorithms on current standard laptop computers.
[12:10] Speaker 2: You are kidding me, a laptop a laptop.
[12:13] Speaker 3: The democratization of computing power combined with these brilliant new
[12:16] Speaker 3: algorithms means scientists can run one thousand unique iterations of
[12:21] Speaker 3: a solar system's berth in a fraction of the time
[12:24] Speaker 3: that used to take to run one flawed model.
[12:26] Speaker 2: That is just incredible. Okay. So here is where it
[12:29] Speaker 2: gets really interesting to me and frankly a bit paradoxical.
[12:32] Speaker 3: Okay, How so I.
[12:34] Speaker 2: Want to push back on the core premise of Hajipores experiment.
[12:38] Speaker 2: If you start with a highly messy, non uniform protoplanetary disc,
[12:43] Speaker 2: if you inject total randomness into the starting line by
[12:45] Speaker 2: throwing these planetesimals everywhere like confetti, shouldn't we expect total
[12:50] Speaker 2: unmitigated chaos at the finish line? I mean, if you
[12:53] Speaker 2: randomize the input a thousand times, why wouldn't you get
[12:56] Speaker 2: a thousand completely unrecognizable bizarrely shapes solar system.
[13:00] Speaker 3: It is the exact assumption that held the entire field
[13:03] Speaker 3: back for thirty years. Yes, we logically assumed that random,
[13:07] Speaker 3: chaotic inputs would inevitably create chaotic, unpredictable outputs.
[13:12] Speaker 2: Because that makes sense in normal life.
[13:13] Speaker 3: It does. But what High Pores Team proved is that
[13:18] Speaker 3: physics is the ultimate organizer.
[13:21] Speaker 2: How So, because gravity doesn't seem like it naturally sorts
[13:24] Speaker 2: things into neat boxes. It just pulls things together.
[13:27] Speaker 3: It's not just gravity, though, it's the interplay of several
[13:31] Speaker 3: absolute physical laws.
[13:32] Speaker 2: Okay, walk me through it.
[13:34] Speaker 3: Think about the mechanics of what is happening in that disc.
[13:37] Speaker 3: You have angular momentum, which forces the collapsing cloud into
[13:40] Speaker 3: a flat, spinning plane, the pancake, the pancake. Then you
[13:44] Speaker 3: have thermodynamics. Close to the star, it's incredibly hot, so
[13:48] Speaker 3: only heavy rocky elements with high melting points can condense.
[13:51] Speaker 2: Makes sense.
[13:52] Speaker 3: Further out past what we call the frost line, temperatures
[13:55] Speaker 3: drop enough for water, ammonia, and methane to freeze into
[13:58] Speaker 3: solid ice grains.
[14:00] Speaker 2: Temperature gradient acts like a giant cosmic filter.
[14:02] Speaker 3: Yes, exactly like a filter. And then you add fluid
[14:05] Speaker 3: dynamics into the mix. The gas in the disk creates
[14:08] Speaker 3: drag on the dust particles. This drag causes the particles
[14:12] Speaker 3: to lose orbital energy and spiral inward towards the star like.
[14:16] Speaker 2: A satellite falling out of orbit.
[14:17] Speaker 3: Precisely, and as they spiral in they collide. They stick
[14:22] Speaker 3: together through static electricity, and they grow into pebbles, then boulders,
[14:26] Speaker 3: than planetesimals. Wow, So physics isn't rolling dice randomly. It
[14:30] Speaker 3: is applying strict rules to random initial conditions.
[14:34] Speaker 2: It's sorting the chaos.
[14:36] Speaker 3: It is when you let those laws operate over millions
[14:39] Speaker 3: of simulated years, they act like a funnel. They herd
[14:43] Speaker 3: the chaotic material into highly predictable architectural patterns.
[14:47] Speaker 2: Order emerges organically from the mess.
[14:49] Speaker 3: It organically emerges.
[14:50] Speaker 2: So when the dust literally settled in these thousand plus simulations,
[14:54] Speaker 2: what did that order actually look like?
[14:56] Speaker 3: Oh? It is amazing.
[14:57] Speaker 2: What were the planetary outcomes?
[14:58] Speaker 3: The results were genuinely astonish. Across these one thousand plus simulations,
[15:03] Speaker 3: starting from completely randomized, messy protoplanetary discs, they found that
[15:07] Speaker 3: the formation of an Earth sized planet located is exactly
[15:11] Speaker 3: one Earth sun distance. Will we call one astronomical unit
[15:15] Speaker 3: or one AU. It emerged as a completely natural, consistent outcome.
[15:20] Speaker 2: But I really want to make sure I'm wrapping my
[15:21] Speaker 2: head around this natural, completely natural, meaning it just formed there.
[15:26] Speaker 2: They didn't have to write a line of code that said, hey,
[15:28] Speaker 2: make sure a planet forms at one AU.
[15:30] Speaker 3: Zero lines of code demanding that outcome. Oh wow, It
[15:34] Speaker 3: organically emerged from the stellar nebula, over and over again.
[15:38] Speaker 3: The friction, the gas drag, the gravitational interactions of the
[15:41] Speaker 3: migrating rocks, the pure physics of a non uniform disc
[15:45] Speaker 3: naturally funnel solid material into an Earth sized planet at
[15:48] Speaker 3: that exact distance from a Sun like star.
[15:51] Speaker 2: That is just wild.
[15:52] Speaker 3: It's not an anomaly. It is an expected standard architectural
[15:56] Speaker 3: feature of this kind of thermodynamic system.
[15:58] Speaker 2: That is staggering. Completely shatters the lucky cosmic accident narrative
[16:03] Speaker 2: we've been clinging to.
[16:04] Speaker 3: It really does.
[16:05] Speaker 2: It is like the physics casino was rigged, but in
[16:07] Speaker 2: the best possible way. No matter how wildly you shuffle
[16:11] Speaker 2: the initial deck of space dust, the house naturally pays
[16:14] Speaker 2: out in Earth.
[16:15] Speaker 3: The math practically guarantees the real estate.
[16:17] Speaker 2: That is amazing. So what about the rest of our
[16:21] Speaker 2: solar neighborhood? Did the simulations churn out our neighbor planets
[16:25] Speaker 2: as well?
[16:25] Speaker 3: They did? Yeah, the simulation showed that a venus like
[16:28] Speaker 3: planet appears about twenty eight percent of the time, okay,
[16:32] Speaker 3: and it successfully clears its orbital path and maintains a
[16:35] Speaker 3: stable orbit.
[16:36] Speaker 2: So if Earth is the jackpot that almost always hips,
[16:39] Speaker 2: Venus is like rolling a very specific pair of dice
[16:43] Speaker 2: roughly a third of the time.
[16:44] Speaker 3: Yeah, it's a very good way to look at it.
[16:46] Speaker 3: And what's incredibly compelling about the venus outcome in these
[16:49] Speaker 3: models is its specific location. What do you mean, Sometimes
[16:52] Speaker 3: this venus like planet settles just outside of the star's
[16:55] Speaker 3: habitable zone, which is where our actual venus ended up
[16:59] Speaker 3: becoming a runaway. Now is healthscare? It's super hot, But
[17:01] Speaker 3: depending on the run sometimes that venus like planet sits
[17:04] Speaker 3: squarely inside the habitable zone.
[17:06] Speaker 2: Inside the habitable zone. Wait, we're definitely going to circle
[17:09] Speaker 2: back to that because the implications there are massive.
[17:11] Speaker 3: Oh they are.
[17:12] Speaker 2: And what about Mars.
[17:13] Speaker 3: Mars also makes regular appearances. Really that consistently shows up
[17:17] Speaker 3: across the simulations as a small rocky object situated precisely
[17:22] Speaker 3: in the vicinity of its current real world orbit, further
[17:25] Speaker 3: out from the one au mark.
[17:27] Speaker 2: So if I'm understanding the gravity of this breakthrough pun intended. Yeah,
[17:31] Speaker 2: pun intended by finally letting go of our human desire
[17:35] Speaker 2: to force the math to build our solar system. The
[17:38] Speaker 2: raw maths just went ahead and build our solar system anyway.
[17:40] Speaker 3: In broad strokes, yes, wow. High Porsch models prove that
[17:44] Speaker 3: a non uniform, messy distribution of solid material is fundamentally
[17:49] Speaker 3: the most viable productive environment for the formation of habitable terrestrial.
[17:53] Speaker 2: Planets because the physics demands it.
[17:56] Speaker 3: Right, our planetary architecture isn't dictated by blind luck. It
[18:00] Speaker 3: is dictated by the inescapable laws of physics. However, there's
[18:04] Speaker 3: a very critical caveat in the research that we have
[18:07] Speaker 3: to address.
[18:07] Speaker 2: Okay, what's the catch?
[18:08] Speaker 3: It involved the butterfly effect.
[18:10] Speaker 4: The butterfly effect like the concept from chaos theory, right, exactly,
[18:13] Speaker 4: the idea that a butterfly flapping its wings in Brazil
[18:16] Speaker 4: can set off a chain of events that causes a
[18:19] Speaker 4: tornado in Texas.
[18:20] Speaker 3: That's the one.
[18:21] Speaker 2: But how does chaos theory apply here if we just
[18:24] Speaker 2: establish that physics guarantees.
[18:26] Speaker 3: Order, Because while the overarching architecture is predictable, the microscopic
[18:31] Speaker 3: details are incredibly sensitive. Oh I see the research explicitly
[18:36] Speaker 3: highlights that while the emergence of a one AU Earth
[18:39] Speaker 3: is a highly probable natural outcome. The exact, fine tuned
[18:44] Speaker 3: reality of a specific solar system relies on tiny initial variations.
[18:49] Speaker 2: So the little things still matter hugely.
[18:51] Speaker 3: A slightly denser clump of dust in one quadrant of
[18:54] Speaker 3: the disk, or say a slightly larger planetary embryo forming
[18:57] Speaker 3: one thousand years earlier than another, that can have a
[19:00] Speaker 3: massive impact on the final layout of that given solar system.
[19:04] Speaker 2: So it's like watching a river carved canyon over millions
[19:07] Speaker 2: of years. Oh, I like this, going like gravity is
[19:09] Speaker 2: the absolute law, right, So it guarantees that the water
[19:12] Speaker 2: will flow downhill and eventually carve a channel. But a
[19:14] Speaker 2: single stubborn boulder near the top of the mountain can
[19:17] Speaker 2: alter the water's path just enough to determine the exact
[19:21] Speaker 2: twists and turns and offshoots of the canyon miles below.
[19:25] Speaker 3: That is a phenomenal analogy. Yeah, the physics of the
[19:29] Speaker 3: river flowing downhill guarantees you will get an Earth at
[19:32] Speaker 3: one au, but that single boulder at the top of
[19:36] Speaker 3: the mountain determines whether your venus ends up inside the
[19:39] Speaker 3: habitable zone or whether your mars ends up a little
[19:42] Speaker 3: larger or smaller.
[19:43] Speaker 2: Right, the fine details exactly.
[19:46] Speaker 3: The overarching blueprint is inevitable, but the hyper specific topography
[19:50] Speaker 3: is highly dependent on exactly how the dust clumped in
[19:53] Speaker 3: the first million years.
[19:54] Speaker 2: Okay, this brings us to a massive pivot point.
[19:57] Speaker 3: Let's do it.
[19:58] Speaker 2: Because if the physics of planet for metion predictably and
[20:01] Speaker 2: reliably churns out these earth like planets at the perfect
[20:04] Speaker 2: distance from their stars, we have to scale this conversation.
[20:07] Speaker 3: Up, we really do.
[20:08] Speaker 2: We have to move from talking about astrophysics and orbital
[20:10] Speaker 2: mechanics to talking about the actual biology that could exist
[20:13] Speaker 2: on those rocks.
[20:14] Speaker 3: Right into the astrobiology.
[20:16] Speaker 2: Exactly because hot high pores model feels like it has
[20:19] Speaker 2: staggering implications for life itself.
[20:21] Speaker 3: It does. It directly addresses what Hi Hyapore refers to
[20:25] Speaker 3: in his work as an eternal puzzle.
[20:27] Speaker 2: The eternal puzzle.
[20:28] Speaker 3: Yeah, the moment you accept that habitable real estate is
[20:32] Speaker 3: common in the universe, you are forced to shift from
[20:35] Speaker 3: modeling dead rocks to considering the imperative for life.
[20:39] Speaker 2: Okay, I want to pump the brakes here for a second,
[20:41] Speaker 2: because this is where I get a bit skeptical.
[20:43] Speaker 3: Fair enough laid on me.
[20:45] Speaker 2: Just because a planet exists at the perfect distance from
[20:47] Speaker 2: a star the right temperature for liquid water doesn't automatically
[20:51] Speaker 2: mean biology's going to happen. Sure, like a warm rock
[20:54] Speaker 2: is still just a rock. How do we bridge the
[20:58] Speaker 2: gap between geological inevitability and biological inevitability?
[21:02] Speaker 3: It is the most important question to ask, and ha
[21:05] Speaker 3: Hypoor approaches it with a lot of scientific grounding. Okay,
[21:08] Speaker 3: he makes a very clear point first, which is that
[21:11] Speaker 3: we do not know exactly how life originated from non
[21:15] Speaker 3: living matter.
[21:16] Speaker 2: Right. The origin of life itself.
[21:17] Speaker 3: A biogenesis, is notoriously difficult to pin down, and he
[21:21] Speaker 3: suggests we likely never will know the exact chemical spark
[21:25] Speaker 3: of genesis.
[21:25] Speaker 2: On Earth, which is fair. I mean, we can't travel
[21:28] Speaker 2: back four billion years to watch amino acids link up
[21:31] Speaker 2: for the first time in a hydrothermal event exactly.
[21:34] Speaker 3: The evidence is just gone. But his focus isn't on
[21:37] Speaker 3: the initial spark. His focus is on the behavior of
[21:40] Speaker 3: the fire once it catches.
[21:41] Speaker 2: Well, since it's burning, right, He points out that.
[21:44] Speaker 3: Once life did originate on Earth, it behaved in a
[21:47] Speaker 3: very specific, deeply integrated way. How do you mean it
[21:51] Speaker 3: didn't just sit passively on the surface, Life difurcated, it
[21:55] Speaker 3: branched out, and it evolves specifically to stay in perfect
[21:58] Speaker 3: sync with Earth's geological and atmospheric evolution.
[22:01] Speaker 2: So what does it mean for life to sync with
[22:03] Speaker 2: geological evolution?
[22:04] Speaker 3: Okay, think about the great oxidation event on Earth.
[22:07] Speaker 2: Great oxidation event.
[22:08] Speaker 3: Yeah, about two point four billion years ago. Early Earth
[22:12] Speaker 3: had almost no free oxygen. Early life was completely anaerobic.
[22:16] Speaker 2: Right, it didn't need oxygen exactly.
[22:18] Speaker 3: But then cyanobacteria evolved the ability to photosynthesize, and they
[22:23] Speaker 3: started pumping massive amounts of oxygen into the.
[22:25] Speaker 2: Atmosphere, which changed everything.
[22:27] Speaker 3: It was a geological and chemical catastrophe for almost all
[22:31] Speaker 3: existing life on the planet. It was a mass extinction.
[22:33] Speaker 2: Oh wow, oxygen was basically toxic to.
[22:36] Speaker 3: Them, highly toxic. But life didn't end it's sync. It
[22:40] Speaker 3: rapidly evolved to utilize that oxygen, which paved the way
[22:43] Speaker 3: for complex multicellular organisms like us. Like us, the biology
[22:48] Speaker 3: and the geology are locked in a coevolutionary dance. As
[22:52] Speaker 3: the planet crust cooled, as tectonic plate shifted, as the
[22:56] Speaker 3: atmosphere changed, life molded itself perfectly to the changing physical parameters.
[23:01] Speaker 2: Ah I see. So, if the physical environment the planet
[23:04] Speaker 2: at ONEAU is an inevitable, predictable outcome of stellar evolution, yes,
[23:10] Speaker 2: and life for ress fundamental nature is to naturally mold
[23:13] Speaker 2: itself to its physical environment, then a universe full of
[23:16] Speaker 2: predictably stable earths provides an incredibly reliable framework for life
[23:21] Speaker 2: to take hold and adapt.
[23:22] Speaker 3: Precisely, you nailed it. If the environmental variables are standard
[23:25] Speaker 3: issue across the galaxy, then the chemical and biological reactions
[23:29] Speaker 3: driven by those variables shouldn't be seen as miraculous. One
[23:32] Speaker 3: offphenomais because these new simulations prove that Earth size planets,
[23:36] Speaker 3: including small super earths, are naturally common in the habitable
[23:40] Speaker 3: zones of solar type stars, it becomes highly logical to
[23:44] Speaker 3: extrapolate that the biological processes we see on Earth could
[23:48] Speaker 3: also be common.
[23:49] Speaker 2: Okay, if we accept that logic. If the math says
[23:52] Speaker 2: the universe should logically be teeming with biology that evolved
[23:56] Speaker 2: on perfectly stable rocks orbiting at exactly ONEAU, which the
[24:00] Speaker 2: math strongly suggests, then I have to ask the question
[24:02] Speaker 2: that is going to frustrate everyone listening.
[24:04] Speaker 3: I think you know what it is.
[24:05] Speaker 2: Why can't we see them Yep, there it is. I mean,
[24:08] Speaker 2: we have telescopes pointed at every patch of the sky.
[24:11] Speaker 2: Isn't it incredibly maddening to have a laptop simulation definitively
[24:16] Speaker 2: tell us that aliens should be everywhere, but it doesn't
[24:19] Speaker 2: give us the coordinates to actually look at them.
[24:21] Speaker 3: It is intensely frustrating, and it is a pain point
[24:23] Speaker 3: the entire astronomical community shares. It's essentially the Fermi paradox. Right,
[24:28] Speaker 3: where is everybody exactly? Well? Ha Hypor addresses this gap
[24:31] Speaker 3: between theory and observation head on.
[24:34] Speaker 2: What does say?
[24:35] Speaker 3: The stark reality is that finding biological life on planets
[24:38] Speaker 3: in other solar systems is currently a nearly impossible.
[24:42] Speaker 2: Task because of the distance distance.
[24:45] Speaker 3: Yes, but mostly because our observational technology, our space telescopes,
[24:49] Speaker 3: our spectrographs. They're simply nowhere near the level of fidelity
[24:53] Speaker 3: required to definitively detect biological signatures on small, rocky exoplanets.
[25:00] Speaker 2: We discover exoplanets all the time, We hear about them
[25:03] Speaker 2: in the news constantly.
[25:04] Speaker 3: We discover them, yes, but primarily through the transit method.
[25:07] Speaker 2: Right, what's that again?
[25:08] Speaker 3: It's watching a star's light dim slightly when a planet
[25:10] Speaker 3: passes in front of it, or the radial velocity method,
[25:13] Speaker 3: which is measuring the microscopic wobble of a star caused
[25:16] Speaker 3: by a planet's gravity.
[25:18] Speaker 2: So we're just seeing shadows and wobbles exactly.
[25:21] Speaker 3: Detecting a planet's existence is vastly different from analyzing its surface.
[25:25] Speaker 3: Oh I see right now. We can barely make out
[25:27] Speaker 3: the basic atmospheric compositions of massive scorching gas giants, let
[25:32] Speaker 3: alone spot the chemical signatures of microbes or forests or
[25:35] Speaker 3: industrial pollution on a tiny, rocky world dozens of light
[25:39] Speaker 3: years away.
[25:40] Speaker 2: The tools just aren't there yet.
[25:42] Speaker 3: The signal to noise ratio is just too massive. We're
[25:45] Speaker 3: looking at a firefly next to a spotlight.
[25:48] Speaker 2: Okay, so we are essentially standing on a mountaintop, legally blind,
[25:52] Speaker 2: staring out at a vast forest. We mathematically know there
[25:55] Speaker 2: should be animals living in the trees, but we just
[25:58] Speaker 2: don't have the binoculars to act see them moving around yet.
[26:02] Speaker 3: That is exactly our current predicament. We lack the visual acuity.
[26:06] Speaker 2: Man. That's rough.
[26:07] Speaker 3: So to answer your inevitable, so wet question.
[26:10] Speaker 2: Yeah, why does this matter if we can't see the results.
[26:13] Speaker 3: The true value of these one thousand plus simulations. Isn't
[26:17] Speaker 3: about pointing a telescope into the sky tonight and waving
[26:20] Speaker 3: at an alien civilization?
[26:21] Speaker 2: Then what is the tangible value? Like why spend the
[26:24] Speaker 2: time and the computational resources randomizing a thousand protoplanetary discs
[26:29] Speaker 2: if it doesn't give us a map to the aliens?
[26:31] Speaker 3: Because it provides us with the foundational recipe for the nursery,
[26:34] Speaker 3: the recipe. Yes, we are finally moving past the era
[26:37] Speaker 3: of guesswork and human bias. We are learning the exact ingredients,
[26:41] Speaker 3: the precise fluid dynamics, the gravitational mechanics, and the sequential
[26:46] Speaker 3: physical steps required to create an environment where life could
[26:49] Speaker 3: eventually spark, bifurcate, and evolve.
[26:52] Speaker 2: Ah, I get it now. So when our technology finally
[26:56] Speaker 2: catches up, when we launch the next generation of massive
[26:59] Speaker 2: space observation tories in the twenty thirties and forties, we
[27:02] Speaker 2: won't just be pointing them at random stars and hoping
[27:05] Speaker 2: for the best.
[27:05] Speaker 3: Exactly, we will know exactly where to point them. It
[27:08] Speaker 3: allows us to deeply understand the genesis characteristics of a
[27:12] Speaker 3: planet like Earth.
[27:13] Speaker 2: We know what the nursery looks like right.
[27:15] Speaker 3: By understanding precisely how the nursery is built from a
[27:17] Speaker 3: chaotic cloud of dust. We know exactly what parameters to
[27:21] Speaker 3: look for. We know the physics of where life has
[27:24] Speaker 3: the absolute best chance to thrive.
[27:26] Speaker 2: We are narrowing the search grid.
[27:27] Speaker 3: We are narrowing the search grid based on universal physical laws,
[27:31] Speaker 3: rather than blindly panning for gold in the infinite cosmic river.
[27:35] Speaker 2: That is profound. I mean, I want to bring this
[27:37] Speaker 2: all together because the journey we've taken today is huge.
[27:40] Speaker 3: It really is a massive shift in perspective.
[27:42] Speaker 2: The bottom line here, as Hypoor's work states so definitively,
[27:47] Speaker 2: is that we have to let go of the idea
[27:49] Speaker 2: that Earth is a fluke.
[27:50] Speaker 3: It is not a fluke.
[27:51] Speaker 2: We've moved from thirty years of restricted assumption heavy models,
[27:56] Speaker 2: where we basically constrained the math to trace a picture
[28:00] Speaker 2: we already drew becake analogy right backing from the photo
[28:03] Speaker 2: to embracing total unmitigated chaos. We randomize the stellar dust,
[28:09] Speaker 2: We let the unyielding laws of physics take the wheel,
[28:12] Speaker 2: and we discovered that an Earth sitting safely in the
[28:15] Speaker 2: habitable zone at exactly one astronomical unit is a mathematical inevitability.
[28:21] Speaker 3: It is simply what solar systems naturally do.
[28:23] Speaker 2: Which fundamentally changes our relationship with the cosmos, doesn't it.
[28:26] Speaker 3: It changes everything. We are no longer the lucky winners
[28:29] Speaker 3: of an impossible lottery. We are an expected feature of
[28:32] Speaker 3: the universe.
[28:32] Speaker 2: It is a phenomenal shift in perspective. But before we
[28:36] Speaker 2: wrap this up, I know there is one specific element
[28:39] Speaker 2: of this research that we discussed earlier that really warrants
[28:41] Speaker 2: a deeper look.
[28:42] Speaker 3: Oh, I know what you're thinking of.
[28:44] Speaker 2: Yeah, what stands out to you is the ultimate takeaway
[28:46] Speaker 2: from all this.
[28:47] Speaker 3: It all comes back to the venus outcome in the simulations,
[28:50] Speaker 3: the eight percent. Yes, we noted earlier that a venus
[28:54] Speaker 3: like planet appears about twenty eight percent of the time,
[28:57] Speaker 3: and critically, because of the butter fly effect, those microscopic
[29:02] Speaker 3: variations in how the dust clumps, sometimes that venus like
[29:06] Speaker 3: planet doesn't end up a toxic greenhouse outside the habitable zone.
[29:10] Speaker 2: Right.
[29:10] Speaker 3: Sometimes it lands squarely inside the habitable zone, right alongside
[29:14] Speaker 3: the inevitable.
[29:14] Speaker 2: Earth, right, Which means a single solar system could theoretically
[29:18] Speaker 2: possess two habitable rocks.
[29:19] Speaker 3: Yes, and if we take everything we've learned today that
[29:23] Speaker 3: the physics predictably builds these planets, and that biology naturally
[29:27] Speaker 3: sinks with its environment. I want you to imagine the
[29:29] Speaker 3: evolutionary implications of a double Earth system, oh man, Two
[29:33] Speaker 3: distinct habitable worlds sharing the exact same sun, born from
[29:37] Speaker 3: the exact same random cloud.
[29:39] Speaker 2: Of dust, just sitting right next door to each other
[29:41] Speaker 2: in space.
[29:41] Speaker 3: Now, introduce the concept of interplanetary panspermia.
[29:44] Speaker 2: Panspermia, that's the life traveling on asteroid's theory.
[29:48] Speaker 3: Exactly in the chaotic early days of a solar system.
[29:52] Speaker 3: Massive asteroid impacts regularly blast chunks of rock off of
[29:57] Speaker 3: planets and into space. We have meteorites from Mars sitting
[30:02] Speaker 3: on Earth right now.
[30:03] Speaker 2: Wait, really, we too, we do.
[30:05] Speaker 3: We found them in Antarctica.
[30:06] Speaker 2: Wow.
[30:06] Speaker 3: Okay, So if life sparks on one of those twin
[30:08] Speaker 3: planets in this double Earth system, a major impact could
[30:11] Speaker 3: easily launch microbial life into orbit, where it travels across
[30:15] Speaker 3: the void and seeds the neighboring planet.
[30:17] Speaker 2: Oh wow, so they would share biological origins.
[30:20] Speaker 3: Think about the evolutionary branches there. You would have a
[30:23] Speaker 3: single origin of life that is violently separated. Landing on
[30:28] Speaker 3: a neighboring world with slightly different gravity, maybe a slightly
[30:31] Speaker 3: different atmospheric pressure. Yeah, you'd have two distinct biospheres evolving
[30:36] Speaker 3: in perfect sync with the respective planets, but completely isolated
[30:39] Speaker 3: from one another, sharing the same night sky for billions
[30:42] Speaker 3: of years.
[30:42] Speaker 2: That is just. It's like a sci fi novel playing
[30:44] Speaker 2: out in real physics.
[30:46] Speaker 3: It is when we look at how predictably physics builds
[30:49] Speaker 3: these systems, we have to realize that the universe might
[30:52] Speaker 3: not just be capable of producing isolated outposts of life,
[30:57] Speaker 3: it might be routinely generating interwoven, multi planetary ecosystems.
[31:02] Speaker 2: That is just. I mean, it completely rewrites how you
[31:05] Speaker 2: view the night sky, doesn't it. We spent all this
[31:07] Speaker 2: time staring at our own slot machine, wondering if we
[31:09] Speaker 2: are completely alone in this dark casino. But when you
[31:12] Speaker 2: strip away the bias and look at how the physical
[31:15] Speaker 2: laws actually construct these systems, you realize the machine is
[31:18] Speaker 2: literally designed to pay.
[31:19] Speaker 3: Out, is rigged to win exactly.
[31:22] Speaker 2: Maybe the real miracle isn't that we exist at all.
[31:24] Speaker 2: Maybe the real miracle is that we are just now
[31:26] Speaker 2: realizing how crowded the universe is bound to be.
[31:29] Speaker 3: I couldn't have said it better myself,
