What's outside the universe?
According to mainstream physics, what is there outside the Universe?
Do the laws of physics in this universe allow for other universes to exist? What is space physics? Does absolute rest or motion exist in the universe? Can you prove to me that our universe is not a simulation? Is there any shape the universe couldn't be? Life Sciences: Is there any another dimension in the universe? How can we prove that our universe is not a simulation? We know universe is expanding but also bodies are attracted by gravity so is it safe to assume that the universe is revolving around something? Is there life in the universe? Could the universe exist without you? What is the shape of the universe? How reasonable is it for us to extrapolate what is out of the observable universe? What are some current theories? Is our universe a non-inertial frame? How? Why? How could the universe appear out of nothing and what was before the big bang? Does the universe exist because no other universes can exist? How do you bootstrap a universe from nothing? Why we are here in the universe? Does the Universe exist? Where is the origin point of the big bang in space? And how far are we from there? Could there exist an Universe, parallel to ours, where the light velocity be greater than in ours, which interacts with our Universe in a subtle way? Is the Universe infinite or is there an end to the Universe? How could the universe have formed from nothing? Why is the universe even present? Is cosmology a science? What is the probable shape of the universe? Can the universe exist without life? Can we cross the border of our universe? What are the proofs of scientists that the universe is expanding? Was there never a beginning to the universe? Is there an end to the universe, and if not, is the universe infinite?
