I'm a little curious because if universe carries on expanding forever, then the universe must be infinite unless it eventually expands in to something or the big rip theory takes place. Any decent answers will be appreciated. Thanks

Assuming that the Universe expands forever, there will never be a point in time when you can say forever has passed. No matter how much time passes it will always be a finite point in time. So Just as time can never reach forever, the Universe can never reach infinite size.
Also if I interpret your question correctly, the Universe is not expanding into anything. It is creating space and reality as it goes, and there are no limits on how long it can continue to do that. Another way of thinking of it is as if the Universe were staying the same size and everything inside was shrinking, although that interpretation would create a lot of conceptualization problems.

Uh, no. The universe may be infinite. But if it's not already infinite then it can't ever become infinite. Even if it expands forever. If it was possible for it to expand to infinite size......then it would have to stop expanding wouldn't it since there would be nowhere else to expand to. Regardless something that is not infinite can never become infinite. It either is infinite or it's not. There is no in between. The universe can not expand "into" anything since the very definition of universe is everything there is. Nothing does, or can, exist outside of our universe. Not even up and down, left and right, can exist outside of space-time. If other universes exist they exist on completely different planes, they are not "out there" somewhere.

not exactly. you see the universe is infinite, yet fianite at the same time. confusing, isn't it? let me explain. imagine our universe as a bubble. we would not be inside the bubble, but on the surface of the bubble. now you could run around the surface of the bubble an infinit number of times, but the bubble is fianite. and the universe will not expand forever. if it did then eventually matter would be so spread out that the universe would be basicly empty, which would meen that the four forces would have nothing to act on, which meens the universe would collapse in on itself.

The universe is infinite, in fact it is a chain of infinities. It will not expand forever. Read my theory (below) to understand more, it will take you 20 minutes and is written in plain English so is easy to understand. Your comments or questions are welcome using the feedback page.

If the universe is infinite it could not keep expanding.

If the universe is infinite, where does it expand to?
