  1. The possibilities are endless. What defines our Universe are the laws of physics and math. In our Universe, gravity has a certain strength, atoms are made up of protons, neutrons, and electrons. These are made up of sub-atomic particles such as quarks and gluons. If there were multiple Universes, all the laws of math and physics could be different. Gravity might have a different strength, water doesn’t exist, atoms are made up of different things, some elements might not exist, 2+2=5 not 4. Everything that defines how our Universe work could be different.
