I've been reading through posts, and I"m nearly sure someone has said the same thing as I'm about to say....
The universe is as big as it's light sphere, outside which, not even light has reached. The space outside the material universe is void. I've heard that the universe is likely 12-14 billon years old, meaning it's exactly 24-28 billion light-years in diameter, and is a perfect sphere.
It might be possible to reach the light-shell of the universe if we were able to travel at the speed of gravity.

conclusion reached and referenced in this page: The speed of gravity is 2x10(to the 10th) c.
