why does light go so fast?
In: Physics
It kinda depends on what you mean by “why”. One reason is because it’s massless. Any and all massless particles will travel at the speed of light. Now if your question is why that speed and not something else, well that doesn’t have an answer (yet). We could pretend to live in a different universe where the laws of physics are different. Maybe in this one, the speed of light is slower. Well that would mean we would experience Einstein’s theory of relativity at everyday speeds which would not be good. It would also mean that atoms fly apart so also not good! But again, we don’t know *why* our universe chose the value it did.
