What If Space is NOT Hollow?
Summary
PBS Space Time explores the concept of spacetime foam, a seething ocean of black holes and wormholes at the Planck scale. By combining the uncertainty of quantum mechanics with the geometry of general relativity, the episode explains how spacetime becomes turbulent and uncertain at the smallest scales. The host details John Wheeler’s analogy of a boiling ocean and discusses how quantum fluctuations in the vacuum create transient geometric distortions. Finally, the episode examines potential methods for testing this theory, such as observing diffraction patterns from distant quasars to detec…
