Do we know in which direction the center of the universe lies?
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? Is the black hole in the center of our galaxy moving? How can we calculate the expanding rate of the universe if it has no center? What is the center of the earth? 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 is the radius of the black hole at the center of our galaxy?

Where is the origin point of the big bang in space? And how far are we from there? Where is the centre of gravity? Does the speculation that our universe is the interior of a black hole in another universe make any sense? If we hypothesize that our universe is similar to a box, then what lies outside the box? Can we even conceive the "space" where the box itself lies? 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? How is the center of gravity applied? Can we cross the border of our universe? How fast is Earth revolving around the center of our galaxy? What does "center of gravity" mean? Is the universe just one side of reality? What is centre of gravity? Are there black holes that are not at the center of galaxies? Could the universe be inside a black hole? Why does a black hole exist at the centre of every galaxy? Does the black hole hold a gateway to another universe?
