If you could travel to the very edge of the universe and look out your ship's window, would there be nothing but pitch black

Maybe not: if the Universe is curved, you would never see an edge. What you would always see is the potion of space farthest away from where you started, until you began to see your starting point in the distance ahead of you.

Maybe not: if the Universe is curved, you would never see an edge.

I just can't wrap my brain around that concept. My brain can only accept forward, backward, up, down, left and right. If I'm at the end of the universe there has to be a direction that I look at that contains nothingness.......

I guess that's why Einstein never returned my calls or PHD physicists never returned my letters and asked me for advice....and my Geometry teacher flunked me...LOL!
