Most say that a closed universe would collapse. Recent observations show that the universe will probably keep on expanding forever. Does this mean we cannot live in a closed universe? Or, is there a loop hole which allows a closed universe to expand forever?

It depends on the geometry of the universe. 2-d analog: blow up a balloon and the surface can expand forever (unless it breaks).
