The Large Hadron Collider can accelerate protons to 99.9999991% the speed of light. Why can’t we reach 100%?
In: Physics
The more massive something is, the harder it is to accelerate it. Light speed is the “speed limit” of the universe because it is how fast things WITHOUT mass – e.g. light – move. Therefore as long as protons have mass, even a little bit, they will never go QUITE as fast as true light.
