Episode notes
Why Light Speed Is Out Of Reach
- Relativity prevents matter from reaching light speed because mass increases sharply and energy requirements approach infinity.
- Particle accelerators confirm particles get heavier as they near light speed, making human travel at light speed implausible.
Wormholes As Hypothetical Shortcuts
- General relativity allows hypothetical shortcuts like wormholes that could link distant points in spacetime nearly instantly.
- Wormholes remain purely theoretical with no observed examples yet, though sci‑fi popularised the idea.
Alpha Centauri And Proxima b
- Alpha Centauri is a three-star system with a close binary and a distant red dwarf, Proxima Centauri.
- Proxima Centauri hosts Proxima b in its habitable zone, making it the closest known exoplanet to Earth.
