There are at least three possible ways the universe will "end" (subjective since ending relies on the human concept of time).

1. Big Crunch.  This theory says gravity will eventually slow the expansion of the universe and cause it to collapse on itself, eventually having all matter pressed into one singularity and probably causing another big bang.  Repeat forever.

2. Big Freeze.  The theory says gravity will not stop the expansion of the universe.  Since it keeps expanding forever, eventually all fuel will be used up leading to the heat death of the universe.

3. Big Rip.  This theory uses the "newly" discovered dark matter, which has so much energy the expansion of the universe keeps accelerating.  Eventually even the atoms in your body will rip apart as they accelerate away from each other.  Think of an expanding balloon with an infinite number of dots on it - each dot expands away from all others.

Which theory do you believe in?  

Yeah, it doesn't matter... Drunkness?

lol - half the topics on this board don't matter.   ;)

I think the universe expands and collapses, repeating this cycle forever. I've heard a theory where time follows a sort of cycle as well, essentially moving in a forward direction and then reversing.

I like Stephen Hawking's theory that the universe we observe is like a bubble on a soap covered pool of water.  A bubble suddenly appears, then over time stretches out (Big Rip) and "pops".   An infinite number of bubbles are created and popped all the time.  

So, true!

From a philosophical point of view, heat death seams real, from a subjective point of view, doesn't matter!

Jesus will return in view of everyone. The dead will rise. Jesus will judge everyone according to the deeds they did in their lifetime. Those who believed in Jesus will go to Heaven - the new heavens and new earth - other reality/other mega-universe. THIS universe will become the lake of fire spoken about in the Revelation, destroying everything, so that God can get His power that He put into it back.

:)

Yes, I know it "doesn't matter", but at the end of each day, these are the things I think about while trying to drift to sleep, instead of who is going to win whatever game.  (Something else that doesn't matter) :)

Space is expanding at an accelerating rate. You've heard of the Hubble telescope? Hubble proved this expansion. Evidence of expansion lead to inflation theory, the big bang. The force driving the expansion, the so called dark matter, is stronger than the gravitational force of all known matter leading to the idea of the big freeze.

Expansion is quantified, it is no longer conjecture. Why though...

So I take it you are a big RIP fan, like me?   :)

Eventually your kind will be extinct and the world will truly be a better off.

Spagettification to quote Dr Tyson.

LOL ! Thank you. I am honored.   :D

does a circle really have an end

True that - their numbers are shrinking every year.  You can't stop education!   :)

So I take it you are a fan of the BIG CRUNCH? 

Just curious. Since we have known for some time that space is expanding, could it be that material is ALL expanding correspondingly. What I am thinking about is that the earth is expanding in size at some basic more-or-less constant rate. And I am not talking about the Neal Adams theory.

The question I have in mind is, could it be this expansion that causes the gravity effect? Perhaps gravity is simply inertia on an expanding planet, making it feel like gravity.

:)

Please go away.  This is not a cult discussion.   :-\

(You are probably too brainwashed to understand, so I just urge everyone else to ignore your nonsense too.)

Isn't it Dark Energy, instead of Dark Matter. Those are different things.

And here are a few more endings:

Big Bounce
Multiverse: no complete end
False vacuum
Cosmic uncertainty

when you said it I thought I might be,
Big Crunch.  This theory says gravity will eventually slow the expansion of the universe and cause it to collapse on itself, eventually having all matter pressed into one singularity and probably causing another big bang.  Repeat forever.
upon further consideration I can't get behind the theory fully, though the oscillatory nature of thus does call for my support. I just have to wonder, what more could there be?

I like playing with the idea that maybe this universe will make love with say, another one and create offspring universi :p
some food for thought

That would be the big "rip" then, or like Stephen Hawking's idea that each universe is like a bubble on a pond.  It's possible two bubbles can intersect and become one larger bubble.  We just need to think of a word larger than "universe" to describe what the pond is.

"Megaverse"?

super- is a Latin prefix meaning over, superverse could work

mega- means a million



yep, I think that's the one. thank you :)

No, I think it already has a name: multiverse.

I think multiverse refers to a number of universes that occupy the same physical space, that are separated by frequency or something like that. 

It's a moot discussion I guess, because I'm sure the physicists have thought of a name for it already.  Stephen Hawking is pretty well respected.  :)

I think this term refers to the perception of one universe within the context of multiple universes. I don't think you would call all the different multiverses out there -the- multiverse.

edit: I stand corrected: http://en.wikipedia.org/wiki/Multiverse
"The multiverse (or meta-universe) is the hypothetical set of infinite or finite possible universes... ."

I was thinking that multiverse referred to all the separate universes, while Vod was looking for a term that encompassed them all as one. Then again maybe it's all the same thing. Perhaps you'd prefer to call it the omniverse or ultraverse?

This was really messing with my head the past couple minutes, the 'maybe it's all the same thing' thing.

and ya, I was thinking of "omniverse" too.

I have read somewhere that universe will end by fire from sky. It makes sense when we look at global warming.

That sounds like the way the world could end.  There are hundreds of trillions of worlds in the one universe that we can observe.   :-\

I don't know if you can say there is something outside the universes, to say they occupy the same physical space. Just as this universe didn't expand into anything, even though it is expanding. So, there probably is no physical space outside that which exists inside each universe for us to use that as reference. But I could be wrong.


I'm not sure there is a difference there. At least, I can't see it.

edit: I forgot. My favorite ending is someone turning off the switch on this virtual reality. And the laws of physics of reality might be different than in this simulation, so we can't very well speculate how that universe will end.

If the calculation of the particle is proved, then about a dozen years from now the universe will disappear at the speed of light. In the future, the universe will be replaced by alternative dimensions.

In the past year, a number of scientists had announced if they have managed to find a subatomic particle that has long been sought. This shows how particles get their mass material. Researchers continue to conduct an analysis of the Higgs Boson particle with a view to ensuring the character of these particles to arrive at the derived particles. So researchers can make sure if they have actually found particles that were once only limited to pure theory.

Actually we exist on a multiverse. Space is infinite and the size of things is infinite. It is possible that in one atom there is many small universe like system on it. And this universe is part of an atom like system. There will be always bigger things and there will be always smaller things it is never ending.

We cannot destroy energy so there will be energy forever,  When a universe expands so much that will absorbed by other verse or some matter will be formed and created a universe again. It is a never ending cycle.

Universe never ends. Only planets/worlds inside it get created and destroyed.

thank you for the sentiments and considerations, friends :)

The Last Question by Isaac Asimov © 1956

http://www.thrivenotes.com/the-last-answer/

You forgot the option of singularity.

Earth will ascend through a positive feedback loop of synchronized conscious energy.  A mass of humans will quickly discover everything is happening at once and evolution will exponentially accelerate until the point of singularity, where the one will defy the energy of gravity by harnessing the infinite power of the feedback loop.

The power of the ascension will be strong enough to lift every human on earth.


Ouroboros.

I was playing around with this idea earlier too. Kind of like how we're getting closer and closer to a consciousness singularity here (I see it, dank does, do you?), I could hypothesize that in the future our universes in the multiverse might merge into a singularity, too, and that might be . /fractalz

---perhaps singularity-realization might represent one of the higher (highest?) rungs of the Sephirot?

Nuke + Chemical Pollution

there's no doubt about that, except sun is getting closer to the earth

Humans will exterminate themselves before universe ends so we will never see it

None of us will be here to see that moment, what a pity!

no one can know what the show will be at worlds end

The end of the universe will not be televised.  ;D

I too believe it is quite possible that we exist within some form of The Matrix. It may be that some highly advanced beings created an exact copy of the omniverse to serve as an archive, allowing them to experience it virtually. I could also simply be a program of an artificial brain running a simulation. Whatever the case may be, contemplating our existence seems to be a part of my programming which I enjoy exercising.  :)

It will not end  ;D

The universe has no beginning or end.

the earth will end with possible bigger asteroids.

Most people enjoy doing it. And fortunately so. What I meant by the last part of my answer was that reality might be so different that we can't easily extrapolate from what we know about this universe to find out how reality will end. But we should definitely keep trying anyway.

Justin Beiber will sing a good song
I think time is on our hands

Don't worry about it. You'll be dead before you notice.   :D

On the contrary, whether it comes from science or religion, I find most people choose to accept the status quo and actually find it a chore to use their brain. Fortunately, we are blessed by extraordinary individuals now and then and this is the only reason why we have managed to make actual progress every once in a while. Einstein said it best, "Great spirits have always encountered violent opposition from mediocre minds." I am in no way suggesting that I am one of these extraordinary individuals, just pointing out that people who think outside the box are not as common as you think.

I completely agree with what you say about the likelihood of our perceptions of the universe turning out to be different from reality. (In fact, all too often this has been proven to be the case.) The scenario I gave of the artificial brain running a simulation also supports this, implying that the laws of physics within its universe could be completely fictitious.

Universe? I dont think it will end. I cant imagine it ending. Earth, earth might end in a nuclear war.

technically when the last organism dies.  which is like a long time away.  and by that time, jesus.   who knows.  2.1 trillion years??  :)

It will just keep expanding at  a slower rate, entropy will keep building up and eventually stars will have used up all the fuel and all the lights will be out.

Very bleak future, but its billions of years away so unless we get a time machine to check it out its just going to remain academic.

I say we will die by heat eventually weather changes so much we cannot go outside.

if the universe compresses into one singularity and creates a new big bang

was it really destroyed?

there wasn't an end

it's a continuum

It's not the universe that will be destroyed, it is evil that will.

what's evil in Uranus?

God and only God will end the existence of this earth, then a new one shall be made, and it will be perfect.

No idiots allowed.  This is a serious poll.   :-\

You're the idiot for making a poll like that.

Big crunch, big freeze? I can't tell if you are trolling or not, legit.

Try a little education. It might do you some good. http://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe
Big Crunch and Big Freeze are explained in detail, but I didn't see any mention of any gods anywhere.

Not going to bother reading through more Wikipedia bullshit, I've learned enough lessons not to try and believe the garbage they put up there.

Way to defend ignorance. I'm certain you haven't read the bible either, yet you have faith in it.  ::)

That's true but it's not.  I used to think the same way, and it's correct that nothing true matters unless you make it.  But you are all that exists.  The universe truly does revolve around each and every one of us, your consciousness is the center of the universe as we project the image of reality from with our mind.

Humans can understand infinity if they reduce the ego's rational mind and improve the function of their creative spiritual mind.

Man may acknowledge no knowledge, but the god inside of you is all understanding and all knowing.

You are more than you could imagine.

i don't think it will ever end, as long as there is human consciousness, so no more need to worry about those Big asteroids

So, just because someone is religious means they can't have an opinion on the matter? Was that comment directed solely at BADecker? Or were you generalizing all religious people as "brainwashed"? You do know that some of us "creationists" also acknowledge science as equally important. As someone who has a real interest in the universe and the physics at play, I personally buy in to the big rip theory as the most plausible end to the universe.

All religious people ARE brainwashed. 

Nice try, but your quote can be applied to any system of learning, including the education system. You know, that place where all of the scientists were systematically indoctrinated based on repetition and confusion. You can apply it to yourself as well.

You're comparing universities where proven science is taught to a cult centre where you promote lies and say "Amen" one hundred times per hour?   ::)

I understand you are full of piss and vinegar from seeing all your brainwashed cult members earlier today, but that is a lame argument.

Let's continue this in more suitable "Scientific proof my god exists" joke thread.  

I was just thinking in my philosophy class today...wrote this down:

"universe sharing information with/awareness of another conceived (possible) universe is the creation of a new universe (in the multiverse) (at least, in our minds)"

(glad you unlocked this thread)



edit: perhaps indeed so long as there is consciousness, we can know the universe exists, as far as we could certainly know, at least. and even then, what isn't perceived as consciousness to us humans could indeed be conscious (say, possibly some conscious system reflected by the movement of celestial bodies together, possible playing with the idea of fractalization).

Since all religious people are brainwashed, when you want to determine which of them are brainwashed more than all the others, you need to examine and compare the evidence. Once you do that, you will see that members of the religon called Atheism (commonly denoted as "atheism") are more brainwashed than any of the more popular religions.

:)

Science is a religion.

God alone has the power to end this world,

Which god are we talking about here? Shiva? Thor? Allah? Or any of the other, likely non-existent, ones?

You forget the part where theory is independently verified through experiment. If experiment shows theory is wrong it is replaced. Please show me which religious dogma is falsifiable and peer reviewed?

Says the scientifically illiterate, homeless, child molester.  ::)

2. Big Freeze seems the most logical. 3 sounds somewhat logical too, except for every atom being ripped apart.

Militant atheists will violently explode as they try and argue with religious people.

I found the answer guys.  
The moment of 'The Big Bang' is when god multiplied the universe by zero. 'The Big Crunch' will be activated when he divides by zero. - will say someone (never)  8)

Then they will feel guilty once they figure out that they were wrong!  :)

"The Method of Science, the Aim of Religion"

the big crunch, I guess.

Not.

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.

I don't think that universe will ever end.
If God, as creator of universe, is eternal, universe is also eternal.

This depends on what God has in mind.

God is tremendously great, beyond imagination. Making a universe like this one is something simple for Him.

Among the reasons that He does things is His own enjoyment. He enjoys when people freely interact with each other and with Him.

Since people in their freedom have resigned themselves to wickedness and destruction (at least some people have), and in such a way that it is in our genes (so we all have, slightly), God will destroy the universe at some time, simply to get rid of every taint of wickedness and destruction that is in it.

There will be a new heavens and a new earth, a new universe that has no wickedness or destruction in it. Some of us will be there, with God, forever.

:)

Hmmmm.. Maybe a big freeze is kinda realistic compared to the 2.

Alien invasion, they ran out of place to stay...

It will end badly, no matter in what way....

end is good

You really think so?

Even Solomon of the Bible said that the end of a thing is better than its beginning.    ;D

2. Big Freeze-  The theory says gravity will not stop the expansion of the universe.  Since it keeps expanding forever, eventually all fuel will be used up leading to the heat death of the universe.

It won't end, it will last forever well at least fix it when it is going to break..

I've read up on number 2--the big freeze but can't really wrap my head around the physics of this. Would anyone care to explain like I'm 5 the theory behind the big freeze aka, heat death of the universe?

1. Scientists will soon prove that blackholes cannot exist. This theory is partially correct regarding the fact that it doesn't end.

2. Wrong. It does not expand forever. Something will most likely happen after the galaxies slows spinning and gets under a particular limit.

3. Stupid theory. the expansion is slowing down at this stage. it is not accelerating.
Dark matter supports the existance of matter. It is not anti-matter.



My theory: I will publish it after very much research.


Don't worrry, before all that our Earth will end. :(

Yeah, this is the most popular theory at the moment I think, I'm no astrophysicist but I'll explain what I know.

Historically, the "Big Crunch" was what most scientists believed. This involved a "Big Bang", an expansion of the universe, then after a while the force of gravity would slow the expansion down. Eventually the force of gravity would overcome the initial force of expansion, causing the universe to begin contracting. This contraction would accelerate, ending in a spectacular "Big Crunch", with all the matter in the universe trying to occupy a single point. Some then speculated that another "Big Bang" would occur, and the cycle would continue.

However, in 1998 the Hubble Telescope observed some distant supernovae which showed that, a few billion years ago, the universe was actually expanding more slowly than it is today. Many more experiments have shown this to be true - The universe seems to not only be still expanding, the expansion is actually accelerating. Now this threw the "Big Crunch" theory out of the window, and caused scientists to make new theories involving something called "dark energy". Although no-one really knows what dark energy is, most scientists believe it's a mysterious energy which repels matter, overcoming the force of gravity (which attracts matter to other matter), and causing the accelerating expansion of the universe.

With these discoveries, it seems that the "Big Freeze" or heat-death of the universe is a likely scenario. In this theory, all matter keeps getting further and further apart, and eventually reaches maximum entropy, where all the energy is spread evenly throughout the whole universe. In such a state, there would be no heat or light, as there wouldn't be enough concentrated energy to sustain the processes. It would be very dark and cold.

However there is the "Big Rip" theory, which I admittedly know very little about, which predicts that the accelerating expansion of the universe will cause it to tear itself apart as a result of dark energy becoming stronger over time. The idea (I think) is that as dark energy gets stronger, it begins to tear apart smaller and smaller objects, until it is strong enough to tear apart subatomic particles, in essence destroying all matter in the universe.

Thank you for the detailed explanation. I feel like I have a better grasp of the concept now.

Will this happen in our lifetime?

My guess is that it will "end" with both a big bang and a big freeze, as they are essentially the same thing in the absence of mass. Mass which would no longer exist in the very distant future in a cold empty universe and didnt exist at the time of the big bang.

Dont take my word for it though:

https://www.youtube.com/watch?v=oBkOYQ02chs

What would happen to said mass? Degrades (expands?) to pure energy? Sorry didn't watch the video

That would be interesting since maybe each atom is a big bang in and of itself

Converted in to energy (photons) by black holes that attract the mass and then evaporate hawking radiation.


ahm. no :). We have a pretty good idea of what an atom is nowadays

:) so it is, since we seem so sure. can you say it definitely isn't?
it just seems that we hypothesize/theorize/find a new particle or subparticle every other year or so

We can never be 100% certain of anything, but all the knowledge we accumulated makes it about as likely as that every shit I take is really a black hole in a parallel universe.

Heat is caused by collisions.  Eventually everything is spaced so far apart there are no more collisions.

Weather will completely change and people would live shorter. There would be scenario like from Waterworld movie...That's my opinion...

Universe is actually a multiverse, once universe will die a new one will be created. The cycle goes one. The universe is basically like an atom.
