Where is the centre of the Universe and where is the edge of the Universe?

Originally these were two questions but I think it is easier to answer them as one and so I have combined them. Firstly there is more than one answer to this since there are two of theories and both will decried.

You may want to ask when you’ve gone through space and you come out of space what comes next. The answer is more space and even when you’ve gone through this there is more space. If you come to the end of space you would find nothing but since nothing is in what space looks like you still haven’t come to end of it. It is thought that the size of the Universe may be infinite and if this is so then there is no edge of the Universe. If there is no edge then the centre of the Universe is everywhere because wherever you are you are the same distance from the ‘edge’ of the Universe. You could argue that since there is no edge there is no centre because there is no where that is the middle.

The second theory is if you went off in space in a straight line you may find your self back where you started. The best way to imagine this if to imagine that you go off in a plane journey and fly due east. In the end you would find yourself back where you started. The navigators compass would be pointing east all the time but until you got to the other side of the Earth you would be going further from the start. After that you would be getting closer to the start. This is because the Earth is a ball. I’m sure you are aware that you don’t go over the horizon and find a singularity. Space may also be like this. It may be curved in another dimension that we can’t see, if this is so then there is again no edge and no centre to the Universe.
