quantum field theory

One of the most bizarre predictions of modern physics is that at the quantum level, subatomic particles are constantly flickering in and out of existence. In this 12-minute episode Subatomic Stories, Fermilab scientist Don Lincoln explains the key idea and briefly describes some compelling experiments that show that this weird phenomenon is really happening.

The subatomic world has long been known to be truly mind-bending, with particles that are waves and vice versa. Cats are alive and dead and everything is governed by probability.
