Episode How To Use a Black Hole To See Your Past
What if the universe is recording everything you’ve ever seen and done?
In this episode, Hannah Fry and Michael Stevens explore the idea that light itself might carry a record of the past. And if it did, how could we watch history unfold by capturing it.
Could a perfectly placed mirror or even a black hole bend that ancient light back to us? Could we watch the pyramids being built, or hear Einstein’s final words?
From a nano-second old reflection in a mirror to the photons drifting through billions of miles of space, they reveal how everything we see is already gone, and uncover surprising truths about time, perception, and our own DNA.
