Big Rip universe will be ripped apart in shreds

BIG RIP : Dramatic end of our universe

There is another possibility of a more dramatic end of this universe. This is called BIG RIP. According to this theory our universe will continue expanding until it disintegrated into more fundamental particle. Like every atom will disintegrated to electrons, protons and neutrons. These particles will turns into quarks meson etc. These particles will break down to more fundamental particle because of this continuous expansion. Finally nothing will be left of our known universe. This is called BIG RIP.

But what is the real fate of our universe. Will it end up in a BIG RIP or BIG CHILL ? Or it will return to the point it started from, the BIG CRUNCH.

In order to know the answer we need to know about our universe and its composition.
