- Tachyons: Hypothetical particles that travel faster than light. They would experience time in reverse. They would have imaginary mass - as in square root of -1. Adding kinetic energy would slow them down; an infinite amount of energy would be needed to slow them to the speed of light. http://www.armaghplanet.com/blog/what-ever-happened-to-tachyons.html 13 comments space
