If you were at the center of the universe it would be equal distance in all directions stemming from your position. If the universe is infinite then each person, each thing, each atom, each point is at the center of the universe because no matter where an object is, it is equal distance of infinity in all directions to the edge of the universe. I'm not a mathematician but I'm sure this could be mathematically proven rather simply.
It also follows that since each object is at the center "everything" is at the same place. Space travel should be easy, since your not going anywhere. For instance if I am at the center of the universe, and Mars is at the center of the universe too, we are both in the same spot already.
This is in contradiction to current theories on the universe that claim it has no center. The universe must have a center or it can't exist. In fact, the universe is all center, because every point contained in it, is the center.
I also propose this can be extended to time. If time has always been and always be then each object is at the exact center of the time line. When the dinosaurs were alive, they were at the center of time, and future events will be at the middle of time also. If that is true then everything is always at the same point in time. Therefore it would be easy to travel through time, because past, present and future are happening all at once.
TA-DA, put that in your pipe and smoke it.
