Just how far does the universe go? Can it be infinite? I get dizzy just thinking about that topic. What if we could travel faster than the speed of light through the universe. If we go long enough, would we return to the same place where we started? Or would we just keep on going forever – assuming we didn’t crash into something that is?

I share the mind-bending effects that are created with the attempted contemplation of the universe. It is amazing to wonder if the stars I have viewed from Earth are really there. Did they cease to exist millions of years ago? Am I looking at light from a star that has not finished its journey through space?
Why do orbiting galaxy clusters with hundreds of millions of stars collide into each other?
What about the edge of the universe? Does it react with an additional universe or universes? Why are hundreds of galactic clusters with hundreds of millions of stars flowing at over a million miles per hour in the direction of the universe’s “edge”?
The number of universes that exist could be greater than all the grains of sand on the Earth.
