What would happen if the universe started contracting?

The Universe would start contracting. Galaxies would draw closer together, until they merge into one mega-galaxy. The newly formed singularity might explode in another Big Bang, creating a brand new universe – with new stars, new planets, new life forms… We don’t know exactly how our Universe will end.

What happens if the universe stopped expanding?

But if there is enough mass in the Universe (composed mostly of dark matter) to eventually stop expansion the the universe would start to contract and eventually become a singularity as its was at the Big Bang. If the universe stopped expanding it would eventually collapse into a singularity and another Big Bang.

Can the universe repeat itself?

It is not possible for the universe to repeat itself again. This answer is based on Gordon’s Theory of Everything and has to do with the details surrounding the Big Bang. Before the Big Bang all the energy in the universe was in the form of the energy of spacetime.

How old is the universe according to ageage?

Age. The universe is currently estimated at roughly 13.8 billion years old, give or take 130 million years.

Why does the universe keep repeating itself?

Your rebirth will happen because the Universe is finite and after a very long time, it will repeat itself. Famous mathematician Henri Poincaré Poincaré recurrence theorem states that if you have a shoe box, you can calculate the amount of time before the quantum material in that box reaches the starting state.

What is the recurrence time for the universe?

Recurrence time for the Universe is a very big number. = number of years until recurrence time. The recurrence time is so long that we won’t ever be able to observe it. Unfortunately the heat death of the Universe will happen long before recurrence time happens.

Will the universe eventually stop expanding?

The universe will eventually stop expanding and start collapsing in on itself, the so-called “Big Crunch.” If the density of the universe is less than this critical density, then the geometry of space is ” open ” and “negatively curved” like the surface of a saddle.
