If someone were to create a universe, where would they put it

Sometimes I read in science magazines that , theoretically at least, scientists could create a universe in the lab. If not now, in the near future. And if they ever succeed,... where do they think they're gonna store this? It's a bit large for a locker, a test tube, or a temperature controlled lab on the second floor. And I'm guessing that Bill's Storage and Rental aint' gonna want it neither.
And, um...isn't creating a universe, no matter the size, just a wee bit dangerous?
This could create some real practical problems, here.

First, we don't understand how universes get "created". We do NOT know how ours started off.

All we (barely) understand is how our own Observable Universe (the portion we can see) has behaved after the moment we call the Planck Time.

This moment is the earliest moment we can analyse using our present scientific knowledge. Before that, the energy density would have been too high for us to understand how things work of what was going on.

In fact (to make matters worst), exactly at the Planck Time, the energy density was so high that we don't even understand how time ifself could have flowed. This does NOT means that there was no time; it simply means that we do not understand.

What we do know is that, at the Planck Time, the initial energy already existed and space was already expanding. So that if our universe did have a "start point" it must have come BEFORE the Planck Time...

...and we do not understand what the word BEFORE would mean at the Planck Time.

However, those who think they have a clue as to how a universe could be created in a lab, think that this new "baby universe" would be stored in... its own universe. It would detach itself from ours (how? we don't know, since creating a new universe involves energy densities higher than that which existed at the Planck Time... and we do not understand how energy behaves at that density).
