Metaphysicians have been talking about this stuff for centuries.
Kant deals with it in the first Critique.
My hot take: there's no meaningful answer to be had to questions like "does the Universe have a boundary?", therefore it's a non-question, therefore don't waste your time asking it. Have an ice-cream instead.
