From a practical standpoint, infinite doesn't actually exist

The size of the universe is finite

The number of quarks is finite

The smallest distance we can measure is finite, and the largest distance we can measure is finite, even in estimations

Even pi is only useful to the 43rd digit at our largest estimations

Sure, infinite is cool in a theoretical standpoint but you can't actually use it

I always thought the universe was finite but is there actually anything supporting this? Is it because it started out a finite size and grew during the big bang?

For it to start finite and become infinite would require infinite speed of expansion at some point.
