Where is the center of mass of the universe?

Hey there, I’ve got a bit of a curious question.

I know that there isn’t a specific ‘center’ of the universe like where the Big Bang happened, and it’s not really a practical concept in cosmology.

But I was wondering, in a theoretical sense, if we were to calculate it, where would the ‘center of mass of the universe’ be?

Just out of pure curiosity, no practical implications here.

Any insights or thoughts would be appreciated!
