Why is the universe big?
Josiah AdamsBecause the event that caused the 'creation' of the universe was unimaginably powerful, and as a result, it has been expanding for a long time.
Because the event that caused the 'creation' of the universe was unimaginably powerful, and as a result, it has been expanding for a long time.
The Big Bang was approx. 13.6 billion years ago - so there has been a lot of time for expansion and it is expanding very fast as the initial hot dense state had so much energy.
I hope that helps!

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
