Time - The History and Future of Everything

So the time between a T-Rex existing and today, is the same as a T-Rex existing and a Stegosaurus.

Spoiler alert. Time does stop. Heat Death is when nothing in the universe changes anymore. The universe becomes an ex-universe, and nothing exists, even nothing. So you might as well get on with doing what you enjoy doing, while you exist and stop worrying about anything, because everything is going to die.

What a cheerful thought.
