Does absolute motion exist?
Does absolute rest or motion exist in the universe?
Is our universe a non-inertial frame? How? Why? Do other universes exist? What is relative motion? And relativity? Do the laws of physics in this universe allow for other universes to exist? According to mainstream physics, what is there outside the Universe? Where does the universe exist? 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 there empty space outside the universe? Do we know in which direction the center of the universe lies? Is it possible to move at 98% the speed of light, then have the entire universe move the other direction at 5% the speed of light? Does reality have to exist? Is there a center in the universe? If so, do we know where is it? What is at the end of the universe? Is the Universe infinite or is there an end to the Universe? Is there any shape the universe couldn't be? Can imaginary time, energy and gravity exist? What is there after the observable universe? Could we ever reach the non-observable universe using time dilation in the same way we could reach Andromeda? Does the Universe have a center? What is at the edge of the observable universe? Could the universe exist without you? What is "absolute" in this world? What is relative motion? How did everything in the universe get here? Is it true that everything in our part of the universe is moving towards the 'Great Attractor'? What is beyond the observable universe? Can the universe exist without life? What does the edge of the Observable Universe look like? How the universe looks like? Does the universe exist because no other universes can exist?
