What is with the sometime hours and hours or delay in having sore/dead/tired legs after over doing and pushing yourself with leg exercise/walking/running? | [

is the concept of light speed defined by light itself, or does light just want to go infinitely fast but physics puts a cap on it? | [

"Because if you could, cause and effect would make no sense and the universe as we know it wouldn't make any sense. The speed of light is the fastest cause and effect can travel.
