I'm voting to close this question as off-topic because this appears to be about metaphysics - as it asks a question about what happens outside the Universe

Brane cosmology? https://en.wikipedia.org/wiki/Brane_cosmology Scientists know very little about life beyond earth. A few simple amino acids and nucleotide precursors have shown up in meteorites, but we've yet to even get a chlorophyll spectrum off any exoplanet. Life beyond our galaxy, far less our universe, is a total unknown.

@alexhits Welcome to Astronomy Stack Exchange! Please note that in science we rarely discuss things without definition. In order to talk about an "outside" of the Universe, you would have to first define what the "outside" is and how we might falsify this theory.
