Hypersonic Physics, Deep Sea Life & Princeton’s Millisecond Qubits (EP. 17)

22 Nov 2025 · 1 h 33 min · S1 E17

Hosted by Lester Nare and Krishna Choudhary, this episode dives into three breakthroughs stretching across aerospace engineering, astrobiology, and quantum computing. We start with a Nature Communications paper from Stevens Institute that experimentally validates a 60-year-old hypothesis underpinning hypersonic flight modeling. Then we head 3,000 meters below the Pacific to explore a newly discovered cold, ultra-alkaline biosphere near the Mariana forearc — a finding that reshapes the search for extraterrestrial life. And we close with Princeton’s millisecond-coherent transmon qubit, a materials science triumph pushing the quantum hardware frontier toward real-world quantum advantage.

Summary

• Hypersonics without supercomputers — Stevens Institute validates the Morkovin hypothesis up to Mach ~6 using krypton-tagging velocimetry, confirming that “simple” turbulence models still work in hypersonic regimes and opening the door to viable, inexpensive hypersonic aircraft design. • Life where it shouldn’t exist — University of Bremen researchers uncover evidence of a chemosynthetic biosphere in the cold, pH-12.6 serpentinizing fluids of the Mariana forearc, offering the clearest Earth analog yet for Enceladus- and Europa-like conditions. • A millisecond qubit breakthrough — Princeton’s tantalum-on-high-resistance-silicon transmon hits 1.7 ms coherence, 15× the industry norm — drop-in compatible with Google/IBM architectures and a major step toward practical quantum computing.
