Is mathematics a closed system, logically speaking?

Hey first time in the subreddit, was just wondering what you guys think.

I am painfully unaware of anything math related but I do want to get into it. Part of that is asking questions!

The universe started with the big bang and it’s continuously increasing. But like is the universe a closed system even tho it started from a single event.

Appreciate yall,

Just a curious dude looking to learn more. Thanks.
