What are Tachyons? This question was posted by Vimal Raj. Answer: Tachyons are hypothetical particles which always travel faster than light. The idea is that, if there is a particle which travels with a speed less than the speed of light, it will never cross the speed of light. But if there are some partricles ...Read the full post
