When time becomes extended as something travels closer to the speed of light, the amount extended is the factor of gamma. Mike Merrifield, an astronomy professor at the University of Nottingham, England, explains how this happens and goes through the set of equations to determine the gamma factor.
Merrifield also takes us into the laws of physics and special relativity — and something called the “light clock” — to explain the phenomenon. The video is on Engineering.com’s “Everyday Engineering” video channel. It was shot by Univ. of Nottingham’s Sixty Symbols.
