Does universe have a center of mass?
Can we discover the center of the Universe?
Is Milky Way near the center of the observable universe or close to the edge? Is there a black hole in the center of our galaxy? Can we say, with certainty, we know exactly what is at the center of the Earth? How can we calculate the expanding rate of the universe if it has no center? Is there a black hole at the center of every galaxy? How big is the black hole at the center of our galaxy? Will we ever find conscious life in the universe? Where does the universe exist? Is the black hole in the center of our galaxy moving? Do other universes exist? How vast is the universe? What is the center of the earth? At the end of the universe, where does everything go? Will the universe still exist for hundreds of billions of years from now? Why is there a black hole at the center of every galaxy? What is the radius of the black hole at the center of our galaxy? Do scientists know for sure what is at the center of earth? Does the universe end? If it does, what exists outside it? Is it true we can know the answer about anything in the universe as long as we have the knowledge to form the question? Is there empty space outside the universe? Is God the universe? Is the big bang even possible? What exists beyond our universe? Some other universe? Is the Big Bang actually possible, or not? Do the laws of physics in this universe allow for other universes to exist? Which place is the center of the earth and how? Where is the origin point of the big bang in space? And how far are we from there? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? Is there anything beyond the universe? How fast is Earth revolving around the center of our galaxy?
