What happens when the Universe ends?

Space Featured Image 4

There has been debate among the scientific community on how the Universe could 'end', and I want to talk and see what others say here!

Anyway, there are many possible outcomes, and I haven't found all the ones out there! So, what will happen to life if it is out there when this immanent event will occur? Will there even be life? What will happen to humans - if indeed we exist or the sun has engulfed our planet and the planets?

I digress. I have gathered some info and figured that there are 4 main theories to the end of the universe.

The big freeze: The universe just expands infinitely and as it does, it becomes colder and colder until it is too cold to sustain life. All the stars eventually burn out and there is no heat to make new ones, so all life dies.

The big crunch: The complete opposite of the big bang! As it expands, gravity eventually stops the expansion, then the Universe contracts and collapses into a point, hence the name.

The bounce effect (I named this as I couldn't find the proper name.): This one is more imaginative but who knows? This effect entails that when the universe reaches it's highest capacity, it starts to shrink, much like the big crunch effect. But when it is at, essentially, it's size at the beginning of time, it expands again, or 'explodes' again like the big bang.

There may be other theories out there, but those are the main ones.

Personally, I believe that the Universe will have the big freeze effect, and it will continue to expand infinitely like it has been doing for 13.8 billion years. The BBC quotes:

Using this new intel, we can discover that the universe could end, depending on the circumstances. It will continue to expand, and 'eventually... freezing out'. This is basically the Big Freeze theory. It also contradicts itsself by saying 'if there is too much stuff, the expansion... will slow down and stop, Then... begin to contract.' This last part is the big crunch.

So, what theory is ultimate? Are any of them really true? Is the end actually inevitable, or so scientists have it all wrong?

    Thank you for this research, intuitive_power. I think it's important to note that your source - the BBC website - says none of this would happen for another 6,000,000,000 years!

    Could you link this information to our big question of whether space exploration is worth the cost?
    And could you provide a link to the BBC website so we can read about it in full for ourselves?

      I did try to link it, but the website didn't accept it for some reason. I'll link the source here: http://www.bbc.co.uk/earth/story/20150602-how-will-the-universe-end

      And sorry, I did forget to link it to the big issue.
      I recently read patient_parrot and brilliant_blackberry's post about what the universe is expanding into and that got me thinking, what happens when it stops? So, I decided to write a post voicing my opinions and thoughts that were made by me reading their post.

    i think all the planets would crumble and all living life would die of suffication unless they are aliens. just what i think would happen. :)

    well i think all planets would vanish and we would all be dead I am not saying this would really happen but its just what i think would happen

    You are right. I think that the big freeze is most likely to happen because as you say the universe will keep expanding and things will keep getting colder and colder and colder until we all die out.

    I think the universe would end in the opposite of the big freeze, the big heat. I'm not saying it would happen but it is creative to theorize and speculate the future! The big heat is not a proven concept [it's made up by me] but here is what it is...

    The universe would eventually boil due to the countless stars being made, then because of the way time around stars bends, gravity would collapse and dark matter and dark energy would be depleted. Time would halt...

    No sources for this comment as the big heat was entirety my thinking.

      That is a really interesting idea! It may not have evidence or sources, and it probably isn't that scientifically correct but it's a cool theory.
