Oldest Molecule, Programmable Proteins, Europa Radar & Light’s Double Life (EP. 3)

1 tim 17 min•14 augusti 2025

We go from the universe’s first chemistry to tomorrow’s designer biology, swing by Mars to tune Europa Clipper’s ice radar, and finish with a fresh take on the double-slit experiment.


In this episode

  • The “oldest molecule” puzzle (HeH⁺), cooling the early universe, and why JWST’s findings matter

  • Programmable proteins: reassigning codons, recoding organisms, and real biosafety

  • Europa Clipper’s REASON radar test at Mars: frequencies, ice thickness & ocean clues

  • Double-slit, demystified: single photons, “which-path” info, and measurement reality
