Is our universe also revolving around some matter?
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?
Our universe is a sphere, but what direction are we expanding in? Are all galaxies moving away from us or are they moving in some specific direction? Is there anything beyond the universe? Can we see beyond the event horizon in the universe? We all knows that universe is expanding. Suppose that there are two different galaxies travelling in the opposite direction from each other at the speed of light. Can one will be able to see the other one ever? Is there an end to the universe, and if not, is the universe infinite? Is there empty space outside the universe? According to mainstream physics, what is there outside the Universe? What's outside the universe? Is there anything bigger than the universe? What is there outside of the Universe? What is beyond the observable universe? Does the universe have an edge? Does the universe have a limit to its expansion? If so, what happens when the universe reaches its limit? Can we cross the border of our universe? 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? What is the things outside universe? Is there gravity in space? What is at the edge of the observable universe? Is there a limit for the expansion of the Universe? What is the thing outside universe? Is it possible that black hole is a tunnel which transfers matter and energy to other parallel universe? Are there more theories for or against our observable universe (93 billion light years across) being inside a black hole? What is outside of the universe or where is universe located. If it was never ending then it would occupy some space and there must be something outside of it. What was that? The Universe have a center, and is on expansion. Wouldn't be more precise to say The Universe could be infinite, but at a moment "x" he have an end? What exists beyond our universe? Some other universe? If a black hole grows larger as it absorbs more of the universe, can it absorb the entire universe given enough time? What will happen when the universe stops expanding? Is it possible to travel to alternate universe? What is the probable shape of the universe? What is outside our universe? Also does it make sense to ask what is outside of the outside of universe? Do the laws of physics in this universe allow for other universes to exist?
