Kind of, but not really. If you were to get in a car and just start driving in one direction without turning or changing course, you would eventually make full circle around the Earth and end up back where you started (let's just pretend here that oceans and other topographical obstacles didn't exist). To your perspective, it would seem as if you were just driving in a straight line the entire time. In reality, the shape of the Earth has brought you all the way back around.
The effect is thought to be the same in the universe as a whole. If you just point in one direction and go, eventually you will be circled back around to where you began. |
What if you consider that the Universe is both every shape, yet none of them? You are referring to space-time curvature, I assume, but what about the fact that red shift tells us some parts of the universe are expanding at faster-than-light speeds?
