There is no boundary to the Universe. The Universe is not flat. It is curved and it curves back onto itself, like the surface of the Earth. Light is embedded in the Universe, kind of like us living on the surface of the Earth but without any means of escaping the surface. Also, the Universe is not infinite. It is 13.5 billion years old so it is about 13.5 billion light years in size (actually it is probably a bit larger since the Universe expanded at a rate faster than the speed of light for a brief period)

I don't think so, because current theory states that the universe was expanding increbily quickly for some time before photons of light as we know it were able to escape from the newly created atoms, etc. And, as others have stated, it is not believed that the universe has any boundaries. But even if it did. I'm not sure that light would ever escape those boundaries because the universe is still expanding.

Just imagine yourself running to the finish line, no matter how fast your run the finish line can never be reached. Thats how the universe and light relate. The universe has expanded so quickly and still expanding that light can never escape the universe. Also light has to deal with matter in the universe which can absorb, reflect, or consume (blackhole) and alter its direction.

As of today, September 03, 2007, there have not been any boundaries to the Universe that have been discovered, reported, detected, or identified. I do not recall ever hearing of a planet or star which bounced off of the sides or walls of the UNIVERSE. Such an event would surely have been reported.

some throries suggest that light actually forms the boundries of the universe as it travels away from the source of the big bang like it's been doing for the past 15 billion years.
expanding into nothing.
but that's just in the 4 dimensions we know of. who knows what else is out there, or right here?

I don't think so. The universe will have curved space around it due to it's huge mass, light that reaches the limits of the universe will follow that curved space.

That's how the universe expands.

What boundary..? All recent observations and research strongly suggests that our universe is infinite, i.e., has no edge or boundary.

No. The universe is infinite.
