Eli5: Why does light travel so fast?
In: 130
This can’t be answered.
I could explain to you some of the mechanics involved, but the ELI5 version is that the speed of light is a simple result of the combination of a handful of physical constants of the universe. It has to be exactly that speed and no other in our universe because of the values of those foundational numbers.
But why are they those numbers? No way to know.
