Apr 1, 2026 They debate the wild physics of lunar transport and why a Moon-to-Earth zip line is a death trap. They unpack space elevators, orbital mechanics and clever lunar-surface zip ideas. They probe why textures register through socks and how touch maps the world. They showcase a brass mechanical calculator and celebrate tactile tools for learning numbers.

Episode notes
Zipline From Moon To Earth Requires Orbit Engineering
- A lunar zipline is theoretically plausible if you engineer orbits and counterweights to keep the Moon and Earth aligned.
- Michael Stevens explains building a cable to a counterweight in high Earth orbit or coupling with a space elevator avoids anchoring towers on both bodies.
Lunar Zipline Implies Weeklong HighSpeed Descent
- A moon-to-Earth cable trip would accelerate continuously and reach orbital speeds, requiring active deceleration and re-entry protection.
- Michael Stevens estimates the journey could take days and you'd reach about seven miles a second by arrival, so passengers need a gondola and heat-shielding.
Zip Lines Are Practical For Moon Surface Travel
- Lunar surface zip lines are a practical idea for intra-lunar transport because the Moon's abrasive dust makes wheeled travel problematic.
- Michael Stevens cites a NASA proposal: zip lines avoid disturbing regolith and protect delicate sites while linking bases and launch pads.
