When the universe collapses after it is done expanding, what will it look like?

Question

According to scientific theory the universe is forever expanding. That is until it reaches its end, when it will then collapse. Physically I wonder what this will be like, as I will probably not be around to see it.

If it were in a movie, everything would probably explode. I on the other hand think blackness would fall as everything is sucked in to nothing.

What are your theories on the subject; and what are the scientific ones if any?

Answer 1

In spite of the best efforts of science to invent scenarios, 'Dark Energy,' to explain the continuing expansion of the universe to counteract the gravitational effects of, Dark Matter,' which should be slowing it down, I think that the inertia of the original expansion from the Big Bang is sufficient to keep it expanding until matter is so thinly spaced that there close to a total vacuum, that's how it will end.

Answer 2

According to scientific theory the universe is not only expanding but the rate of expansion is accelerating. The theory you subscribe to is outdated. The universe will continue to expand until there are no more stars alive to bring light. All matter will either become black holes, neutron stars or black dwarfs (cold crystallized white dwarfs) with some cold frozen debris, called planets, strewn about.

-edit-
Yes this is hundreds of billions, it not trillions, of years into the future. A red dwarf star can have a mainsequence lifespan of a trillion years. And such stars are still being born. The following white dwarf will radiate off its last gravitational heat in about another 10 billion years or so. No white dwarf ever born has ever disappeared. The universe is too young...

Don´t panic.

Answer 3

No evidence for it to collapse--only a bad theory. The universe is expanding and accelerating so there must be a force beyond an explosive event guiding it. Explosions only create disorder, chaos and a loss of energy....not possible for exploded matter to collapse back into itself.
The Bible says that God "stretched out the heavens" which is a good explanation of what is being observed. The Bible also states that by faith we believe that "what is seen came from that which is not seen"---a good way of explaining the atomic and sub-atomic structure of the universe.

Answer 4

Per Physics and cosmology Theory if black hole really existed ,then as per their characteristic of gravity ,they would prevent an expansion of the Universe by Pulling in mass inwardly not pushing it outwardly.
There are too many question and misinterpretations about expansion and contraction of the Universe to ascertain anything plausible yet.

Presently there is a great doubt that Black holes really exist. The question of black hole existence was bought up in a publication by Abhas Mitra of a paper which showed that black holes by definition do not exist.

Answer 5

i have never heard that it will collapse. if your refering to the big crunch and oscillation theory that theory isnt very popular anymore. the universe is accelerating instead of slowing down due to dark energy, so they dont really think it will collapse.

and what dr anders is refering to will take hundreds of billions of years for alll of the stars to become black holes considering that more then 99% of them do not form black holes and just creat debris that a new star can aris from. so basically there still always be some stars. but in a few hundreds of billions of years for most of the stars to die and create black holes.
