Cycle Explosion Implosion

In summary, the universe's full cycle involves a process of expansion and contraction over billions of years, starting with a big bang and eventually collapsing back into a singularity. This cycle is caused by the force of gravity and the distribution of matter and energy within the universe. The expansion phase is estimated to have lasted around 13.8 billion years, while the contraction phase may take trillions of years. It is uncertain if the cycle will continue indefinitely, with some theories proposing a steady state and others suggesting endless cycles. During the implosion phase, the universe will become increasingly hot and dense, leading to the destruction of all matter, including life forms.

While Universe now continue to expand due to the last BB, there is growing vacuum in the midst of it which with time will reach such tremendous value that the expansion will be stopped and the reverse process will start ?

The vacuum is precisely the thing which is causing the expansion though. So that should only increase the expansion, not stop it.

1. What is the universe's full cycle?

The universe's full cycle refers to the process of expansion and contraction of the universe over billions of years. It is believed that the universe began with a big bang, expanding rapidly and then eventually slowing down. After a certain point, the universe will start to contract and eventually collapse back into a singularity.

2. What causes the universe to expand and contract?

The expansion and contraction of the universe is caused by the force of gravity and the distribution of matter and energy within the universe. During the expansion phase, the force of gravity is not strong enough to overcome the expansion, but as the universe ages and matter becomes more concentrated, gravity becomes stronger and begins to pull everything back together.

3. How long does each phase of the universe's cycle last?

The expansion phase of the universe's cycle is estimated to have lasted around 13.8 billion years since the big bang. The contraction phase, or implosion, is predicted to take much longer, potentially trillions of years, as the force of gravity is much weaker and takes longer to pull everything back together.

4. Will the universe's cycle continue indefinitely?

It is currently unknown if the universe's cycle will continue indefinitely. Some theories suggest that the universe may reach a point where it stops expanding and contracting, and instead remains in a steady state. Others propose that the cycle will continue endlessly, with each cycle being slightly different from the last.

5. What will happen to us during the implosion phase of the universe's cycle?

During the implosion phase, the universe will become increasingly hot and dense as everything is pulled back together. It is believed that this will eventually lead to the destruction of all matter, including planets and stars. It is unknown what will happen to life forms during this phase, but it is likely that they will not survive the extreme conditions.
