So /sci/, what will ultimately happen to our universe? When? Why?

[Anonymous No.5726674]

Go to /x/, this is science. That can't be measured, so it's not in its scope.

[Anonymous No.5726679]

We don't know. There are many theories, none have much evidence.

[Anonymous No.5726684]

>>5726674
But I've seen several theories by seemingly reputable scientists...does this mean we won't necessarily have a dark, empty universe?

[Anonymous No.5726689]

>>5726668
The prevailing theory so far is the Heat Death scenario

[Anonymous No.5726690]

Funny you should ask, I was talking to a few aliens 8 billion years ago about this very same question in a bar on the far side of the Andromeda Galaxy. Let me put it this way. We're in for it. First you will see that the expansion of the universe continues as expected. Glakkar the Magnificent got that much right during the First Billion Years. We know that stars live and die and everything moves apart. But what he couldn't have figured out then is that all the black holes in the universe will eventually evaporate due to Hawking radiation and any protons that managed to avoid being swallowed up by them might still be subject to proton decay. Everything is going to go dark and there will only be radiation to occupy the vast reaches of space, although the average temperature of the universe will be so low by that time that nothing interesting could possibly happen anymore. Despite what your coworkers say, you being alive is interesting, so that has to go away by the time the universe realizes its heat death. We are all doomed.

We reach maximum entropy, at which time some ghostly force compresses everything back into a singularity, we go boom and everything starts over.

Will gravity eventually force everything in the universe to collapse on itself?

[Anonymous No.5726827]

Glad to know a based computer will solve entropy.

[Anonymous No.5726843]

(first post) Space is an unpredictable and beautiful thing. We have no ability to tell what is going to happen. There are three basic possibilities, the universe will expand indefinently and cool down and freeze, the universe will stop growing and stay the same, and lastly the universe will reach critical mass then collapse in on itself(an even know as the Big Crunch). There is nothing we can do but watch in amazement of our mighty universe.

[Anonymous No.5726850]

What will happen when the universe reaches heat death? Will everything move still or will everything move at the speed of light?

[Anonymous No.5726853]

it will burn out. Our universe might be packed with burned out galaxies. But since they are dark, we can't see them.

I guess eventually everything will be neutron stars. These neutron stars will clump together, and then we will have another big bang like event.

that shit is scary

Who said it isnt an infinitely bigger being peeking its beedy eye into a dream its manifested idiot non belief leads to destruction of ITS creation therefore global holocaust is being slowly manifested apon you all, the evil in which this entity balances and keeps at bay currently is at a all time low due to constant technological and biological attack. this and the lack of your focus of the love positive balance by supporting this very entity that enables you to FUNCTION corruption of conciousness/soul through media perverse trends and the nearing said new world order an existance without source in a universe of peace and prosperity without it is literally suicide your just throwing fancy words at saying youll prosper without the creator/source a selfish manifestation of lust greed ect ect echoing throughout

When u push the creator or god away its loveless existence define such an existance without things u love.. this, enabling limitles destruction of existence you are now fully aware of being in support of this decieving humankind and all walks of life by stating what is posted at your fingertips explain why if im not mistaking your arrogance has blinded u from such a truth that is of so much devestation throught this solar system if not universe.

a universal collapse.

a universal collapse
a universal conspiracy
the ultimate singularity
But the singularity might be evil, how do you know which is which? Ray Kurzweil might not be able to help us. The robots might merge with us too violently. How can you know man? How can you know? AGGGGHH

WHAT DO WE DO NOW
Let's ask EK :DDDDD

Heat death won't happen because as the universe is accelerating its expansion, there will always be more volume/space created and therefore no upper limit on the entropy, entropy can increase forever

in fact, when everything is homogenous enough throughout the insanely expanded space, you could argue that there'll be 0 entropy at that point in time

> We don't know. There are many theories, none have much evidence.

Bullshit. We know full well from a LOT of evidence that the universe is expanding, and that the universe is very likely to continue expanding. So a "heat death" of some sort is very likely to be the end result of our universe.

[Anonymous No.5727896]

>>5727863
Is it really speeding up in its expansion?

[Anonymous No.5727897]

>>5726769
> Is there anything we can do?

No. This has to do with physical law, You are subject to physical law. Entropy wins eventually, meaning everything will wind down to a state where no differences in heat can be exploited in order to do work. Radiation will just echo in lower order throughout the otherwise empty universe, forever.

Unless there's a Big Rip, which will happen much faster (100 billion to 100 trillion years), in which case each particle will be effectively isolated in a universe of its own.

[Anonymous No.5727902]

>>5727896

The speeding up is inferred from the proposed nature of dark energy. It seems anti-intuitive, but when space is 'created' by the expansion of the universe, it also creates dark energy, which adds to the 'force' of the expansion. It's like a bomb whose explosion produces more fuel and oxidizer for the explosion, etc.

The Big Rip theory desperately needs more evidence. And we're not likely to get any until we isolate what dark energy is.

[Anonymous No.5727905]

>>5726853

No. The clumping effect due to motion and gravitation will be overcome by the universe's expansion. Literally, if all the matter in the universe were clumped in one place today, the rest of space would continue to expand. Matter and space are different. Please understand this. The expansion of space is NOT the expansion of matter.
