Just how big do you think the universe really is? There are some models based on theories of inflation, and the presumed percentage of the universe that can be observed. Here is what wiki has to say on the subject

and here is an interesting article on it too

As far as I know, the universe is estimated to be 130 billion light years in scale.

So when you travel to the edge of the universe and want to keep going... what happens?

Just because the universe may have a definite size, it doesn't mean that it has to have a boundary.

This question is like asking what were to happen if you were to reach the edge of the Earth.
