Is Quantum Tunneling Faster than Light? | Space Time | PBS Digital Studios

The video explores the peculiarities of quantum mechanics, focusing on the uncertainty of quantum states and the concept of wave function collapse. It introduces the de Broglie wavelength, explaining how it relates to an object's position and momentum. The phenomenon of quantum tunneling is discussed, highlighting its significance in radioactive decay and nuclear fusion. An experiment is described to test the speed of tunneling photons, suggesting faster-than-light travel within quantum limits. The video concludes with the implications of quantum mechanics on space-time and the potential for causality violations.
