Good question! No one really knows how many universes there are. Some people think there is just one but there are some complex ideas with lots of hard maths that believe there could be lots and lots of universes and we’re just in one of them.
In space, there’s only one universe but there might be other universes somewhere.
The problem is that “somewhere” might be a place we can never reach or study so at the moment it based purely on theory and maths without scientific experimental data to prove it.
