It's believed to be curved in on itself, like the earth, except that the earth has a curved 2-D surface, in 3-D space, whereas the universe has a curved 3-D surface in 4-D space-time. As such, it doesn't end, it curves round and in principle should take you back to where you started if you traveled far enough. Good choice for infinite.
That was a good choice, I like the texture on the moon, good job!
ReplyDeletevery original darr, i love that colored meteor that is going to crash into that NASA satellite.
