The fact that light can only travel so fast proves the existence of time! The thought of putting a sign on a planet that is then seen 100 million years later because it takes that long for the light to reach that place... I think that proves time right? However, how fast is the universe expanding? Does it expand faster than the speed of light at some point? Is there a relative curve that speed operates on? Is it linear or exponential?
