[QUOTE=showtek;25131504]You cant get something from nothing.
Space has not always* been there. Where the fuck did it come from? This is starting to piss me off now. Are we just an ingredient in gods chemistry set?
I wonder if any aliens out there know the answer? But how could they know?
Im done wrecking my brain for one day...[/QUOTE]
The best answer to this.... We don't know. You can CLAIM to know but you really don't. *shrugs*
[QUOTE=AidanCKY;25131898]It confuses me... I dont understand how infinity is possible. If its not infinite, how is it enclosed? and enclosed by what? if it IS infinite, how does that physically work?[/QUOTE]
It really isnt that hard.
Time needs space to exist (spacetime) Space and time need Mass to exist.
At the edges of the universe there is no mass so time and space doesnt exist there.
Flying there will "probably" slow down time until an infinite small number the farther away you get from the mass.
[QUOTE=windwakr;25131757]If the universe isn't infinite, what would happen if you went outside of it?[/QUOTE]
You'd cease existing.
[QUOTE=dooboo2;25131957]In reality, infinity cannot exist. If that is true then how can our universe be infinite? It can't. It will expand to the point of collapse and form another big bang, creating the next universe. This is how our universe was formed and how it will die.
or at least that's what i think[/QUOTE]
Then why is the expansion of the universe accelerating, well the galaxies are so the expansion of our universe could be accelerating from our observations.
Questions like this make me want to freeze myself, Fry style, so I can see if we have an answer to it in the future.. :frown:
the real answer is, who gives a shit? we're never gonna find out anyway, at least in our lifetime.
Here's something to think about: our intuition, our sense of how the world works, is limited to a very narrow set of conditions. We're not used to things moving very fast. It's not intuitive that a thirty-ton airplane could fly, but that's because the speeds and forces involved are beyond our familiarity. Even more so with near-lightspeed travel, time dilation, etc. It's hard to wrap the mind around.
Or look at the grand canyon. It's not intuitive that it could be carved out simply by the flow of water, but that's because we are used to thinking in much shorter timeframes, because that's how we live.
The forces that govern the universe are even farther from what we are used to. It shouldn't be surprising that they don't seem "right" or "natural" given that we are used to dealing with small, slow-moving objects over brief periods of time.
We haven't come far enough to realise this, and to be honest I don't see how it could possibly give us any advantage.

Exspansion is deccelerating.
Big bang.
Look up some quantum theories OP.
1. It is theorized that the universe is a closed system, i.e. once you get to the edge of it, you start back at the opposite edge, like with a circle.
2. Think of the everything in terms of energy, seeing as mass is basically energy. You cannot make or destroy energy, so you are probably asking how the universe can be so big and have so much mass and yet come from a single particle? Well, you have to think of gravity as negative energy. It is theorized that if you take the sum of all of the mass in the universe and subtract it by the sum of all of the gravitational force, that it would be 0.
Both of these are just theories, seeing as both of them cannot be tested, but I hope they have helped with your conundrum.
[QUOTE=MovingSalad;25131526]Stephen Hawking said that for the universe to be constantly expanding, which he believes it to be (through mathematical, and scientific physical evidence and speculation), it must be contained WITHIN something.
What that something is has not been established by humans.
Yet.[/QUOTE]
Since I was a kid I always imagined the infinite universe as a sphere, because if you are inside a sphere then there is no beggining or end. I also imagined said sphere to be connected by tunnels to more spheres like that, with infinite ramifications. It was an interesting idea :v:

it is contained within in the internet because isn't the internet constantly expanding :tinfoil:
wait that makes no sence what so ever...whatever

Quantum Fluctuations.
Lo and behold I just answered the age old question where the universe came from now can we shut the fuck up with all this retarded pseudo philosophical bullshit please.
The galaxy we reside in right now is 100K LY across, 12LY thick.
To think that we are an "ingredient" in gods chemistry set, is small thinking in a large universe.
To think that our chance of encountering extraterrestrial intelligence is minimal, that is also, very small thinking.

Simply our brains are not adapt to dealing with such large distances, time scales, and speeds.
[QUOTE=-xxsetshotxx-;25131570]Don't try to think about it; your brain will explode. The human mind doesn't have the concept of infinite/forever; we only know beginning and end. We only know cause and effect. Because our lives are based on beginnings and ends, we expect there to be a beginning and end to everything. So it's likely that there was always something here, with no beginning and no end.[/QUOTE]
No I like to think I understand the concept of infinity, thanks.

That was wrecking your brain? Get out of here, you over-religious silly-head.
Also; you very well fucking don't know that we can't get something from nothing, or that there was 'nothing' when the universe speared into existence. So please shut up.
All this is :psypop:
I think some people are asking absurd questions here.
Where does space "come from"? You're modelling the existence of the universe, even the existence of time itself on the idea of "something 'coming from' something else", a concept that's dependent on both space [i]and[/i] time, even though it's been established that neither of those exist, before they exist (ie, before the universe). I think most people think about these things absurdly, you cannot try to picture these things using systems we're used to in our universe, such as cause and effect (ie, where did space 'come from'). It's pointless to even talk about space "moving into" something or attempt to "visualise" it when we're probably not even talking about our regular three dimensions. For all you know, space is only "moving into" itself via some extra spacial dimension but to us it looks like expansion. Don't forget, to a goldfish, existence is a bowl. When it tries to look out, it only sees its own reflection.
Space is space, literally empty space. Space is literally nothing, not something. There just happens to be a lot of shit floating around. You can't create nothing out of nothing, so that nothing is space.

You do know that space isn't empty right?
Even perfectly "empty" space is comprised of the Quantum foam

That is only a theory and he is partly correct. Space is mostly nothing, with very rare occurrences of bodies of matter.

From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

And dark matter? I suppose that doesn't exist either, it's just 'spaecz'
Why does the universe have to collapse? Why can't everything spead enough that it escapes everything elses gravotaional pull, and so the universe either stops or floats apart until everything is very isolated. And if the universe does loop round then maybe this happens until everything loops round and meets back in to the middle, therefore ends up [i]accelerating[/i].
Everything is a theory, and the quantum foam is part of Quantum field theory, which to my understanding is a pretty sound theory.
And yes physically space is empty, but in terms of energy, it isn't.

The universe is accelerating, but everything is pushing away from each other, and the universe isn't some infinite loop because that would mean that if we looked far enough away into the universe then we could see the backs of our own heads.
We can't.
