Can Space Be Infinitely Divided?
Summary
This episode explores the Planck length, the theoretical minimum scale at which the concept of distance loses meaning. By combining quantum mechanics and general relativity, the host explains why attempts to measure smaller distances create black holes or spacetime foam. The discussion highlights how fundamental constants define this limit, suggesting that space may not be continuous but rather fluctuates at the quantum level.
