>If the universe is infinite
Who the fuck ever said the universe is infinite?
Most people in this thread will assume you're talking about infinite space, which is a topic of debate as to whether the universe is open or closed. However.....

>how come the sky isn't lit up like the surface of the sun
You question is not about infinite space. What your question implies would require infinite mass/energy in the universe. If there were either infinite energy OR infinite mass ANYWHERE in the known universe then the entire universe would collapse under the infinite gravity generated by this infinite energy/mass.

In short, any universe with infinite energy/mass simply can't exist for any length of time. Infinite space however, is still plausible, but again, infinite space has nothing to do with your original question.

Infinity can only exist in this universe if we live in an open universe. If you could mathematically prove infinity does or doesn't exist, then could you prove whether the universe will end or not?
