As i said before our universe is expanding with a rate of 72 km/s/Mpc for more details check my previous posts.
So everything as a end it even applies for our universe too ,so how our universe have its death ,they are:
1. Big rip:
Since the rate of expansion of our universe doubles every 1 Mpc, so it will be difficult for the gravity of galaxies,stars to hold there particles.
at one stage our universe will expand at light speed that time it will be like we stuck in a black hole, that is even the atoms disintegrates .
2.Big freeze:
The Big Freeze (or Big Chill) is a scenario under which continued expansion results in a universe that asymptotically approaches absolute zero temperature.In this scenario, stars are expected to form normally for 1012 to 1014 (1–100 trillion) years, but eventually the supply of gas needed for star formation will be exhausted. As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Eventually black holes will dominate the universe, which themselves will disappear over time as they emit Hawking radiation.
3. Big crunch&Big bounce:
After trillion of years the force of gravity will excel the rate of uni verse and that time contraction of universe takes, this
the temperature of the universe rises more than the outer surface of many stars and this also led to the combination of many super massive black holes and eventually erasing everything.
The Big Bang to occur immediately after the Big Crunch of a preceding universe.
The big bounce theory states that :
"the universe will continuously repeat the cycle of a Big Bang, followed up with a Big Crunch."
