The physics wish list meets science’s hard limits
The Skeptics Guide #1105 - Sep 12 2026
The episode tests whether transformative technologies such as faster-than-light travel, teleportation, and unlimited energy would solve human problems or create larger ones.
- 1The panel finds that changing physics could unlock extraordinary technologies while introducing risks no safeguard could easily contain.
- 2Real science grounds the speculation, from Roman’s wide-field space surveys to infant learning and embodied robot training.
- 3The closing AI discussion separates practical competence from consciousness as the more consequential question for civilization.

The panel weighs whether faster-than-light travel would enable exploration or expose Earth to hostile alien civilizations.
The brief
At DragonCon, Christian Hubicki joins the panel to ask which law of physics they would change, turning wish-list technologies into questions about unintended consequences.
Faster-than-light travel, time travel, teleportation, anti-gravity, and unlimited energy promise abundance and exploration, but each also creates hazards involving aliens, weapons, privacy, or planetary stability.
The conversation returns to real science with the Nancy Grace Roman Space Telescope, infant cause-and-effect learning, embodied robots, and modern tests of Galileo’s equivalence principle.
The standout tension is whether a physics change should serve humanity broadly or merely grant an individual’s wish, especially when the consequences cannot be reversed.
The episode closes by arguing that AI may transform civilization through competence alone, without resolving whether consciousness or artificial general intelligence is necessary.
