I don’t think it’s possible to say. Our current definitions of spacetime is limited to what is in the observable universe. What’s on the other side could be a whole different universe with similar spacetime. Or it could be an infinite void. Or it could literally not exist. Or it could be a vast sea of cream cheese. We don’t know, and according to our current understanding of physics, it is impossible for us to ever know. Edit: not a physicist by the way, would also love someone who actually knows what they’re talking about to butt in.
