Exploring the Concept of Light Speed and Tachyons

The concept discusses the possibility of light traveling infinitely fast, suggesting that space may be creating a limit for light. It questions what light is traveling through if not space and speculates that if light is not traveling through space, then it does not have speed. The conversation touches on the idea of tachyons, particles that move faster than light, mentioning that while matter cannot accelerate to the speed of light according to Einstein's equations, acknowledging the existence of something faster than light could lead to properties where time moves backwards, hinting at the existence of a universe running in reverse.
