The expansion of the universe is still happening on a big scale; however, local events like asteroids smashing into Jupiter and a ball falling back to Earth overcome this expansion just as a colapsing star would.

Gravity becomes repulsive once it reaches Planck's constant, forcing it to invert. Loop quantum gravity states that there was an already collapsing universe which resulted in the "big bounce", or a Big Bang (with infinite density) and a Big Crunch. Basically, a universe only occurs between when matter expands and when it contracts.
