What exactly is beyond the known Universe?

I apologize if this is in the wrong place, I wasn't quite sure if this belongs in General Chit-Chat or here. But I don't think its been done before...

Anyway, what do you think is beyond the known Universe? I'd imagine that we know only a very small fraction of, well, everything. I've got a program called Deep Space Explorer (anyone else got that?) and if you zoom out enough, to billions and billions and billions of light years away, you will see the 'outer casing' of the Universe, which probably doesn't exsist; then theres nothing. But I doubt its nothing.

So, do you think the known Universe; everything that exsists, ever ends? And what is there then? Nothing? But surely nothing is something?

Post your thoughts.

I don't think it will end, because there actually no beginning either. How did the universe exist? what is the cause of the existence of the universe?How did the cause exist? it's so infinite. So I think there is no beginning or an end.

But I don't believe in 'nothing', theres always something. There must be a beggining and an end, maybe there was nothing at the start, but that makes that 'nothingness' the beggining, so if its the beggining - then its something. If you get what I mean.

So there must be a beggining and an end.

'Nothing'. No empty space to occupy matter, energy, or anything.

The human mind can't easily comprehend the idea of infinity or absolute nothing.

If the big bang theory is correct, then there will be a point that no matter has reached yet, but then there may have been another big bang somewhere else... well, why not?

If there was no big bang I dunno, it's strange, because 'space' can't have an end... but, I don't think there could be things going for ever.

Also, whenever I start thinking about the big bang, I also think about what would 'be' if it hadn't of happened.

I know that everything has a beginning and an end. But if the universe starts from somewhere, or if everything has started from somewhere, how did the start of all things started?

From the Big Bang, that is what's believed. So the 'Big Bang' is the start. So before the Big Bang, there was nothing, but thats something because its nothing, and thats something.

Which means, its infite, comkpletely infite and endless, it has no start. But with my theory that there can be a nothing. That would be impossible. Its all very confusing. As if nothing can't exsist. Which it just can't, can it? Atleat it would never be nothing, only if time stopped. If nothing is when time and space stops, and there is no energy or anything, there is something or it wouldn't exsist.

Sure it would be easy to explain if there was 'nothing', but there just can't be a nothing... its probably the hardest thing to understand to man. Well, its impossible to understand.

According to many scientists, the Big Bang was an expansion of space, not the creation of it. Before the Big Bang was a single point of singularity.

But it's sure interesting to discuss it. Well I understand your point about the whole "nothing" theory. It's very hard to understand if everything has started with nothing, then how can a nothing exist if it's nothing?But my point is that it's very hard to understand that nothing is actually something.

Well its not really, if something has a name, a location or just an exsistance it becomes something. So if this 'nothing' has an exsistance, wouldn't it be something?

As soon as nothing 'appeared' from well, nothing, which would be something if its come from nothing, hich is already something as it would've already exsisted in time and space. If its infinite, there could never be a nothing, as soon as it enters time (which could never stop, its not as liquid, solid or gas, or a partical, you could say its magic) it would become something.

And yes, it is a very, very interesting topic to discuss, but its mind numbingly confusing. It can never be understood, by any organism. And only organisms have a mild understanding of the world/universe/'nothingness' around us.

The Big Bang is just a theory, not actual fact . Much like the theory of evolution, it has many gaps and inconsistencies, that´s why I don´t thrust this type of theories, because they are incomplete. As for the universe, I think it´s never ending. It expands to distances only our imagination can visit. jejejejjeje I´ll put it to you this way: If we don´t know the beginning of something, what makes believe we´ll ever know the end of it.

Well that's a great pity I must say, I really like to know how things are, how things have been made in the universe, how things exist. Maybe we never know or maybe we will in our second life?

How could we? If all organisms could never know. No human or animal would live long enough to witness the end of the Universe, plus the fact that the known Universe is infinite.

And forever expanding! I think thats a fact...

yes I know, but have you ever thought of "if you die then your spirit still lives, but you body doesn't?" But if you think good enough this dying thing comes to your theory afterall.
Because if you die than your nothing, but in you theory does prove that if there is nothing but it exist than it's something. Now I know that if you're something, than you die, than you're nothing. But nothing is also something. So you can proof that after you die that you're still alive in a other way than you lived before.

the fact that the known Universe is infinite.

Nope, It's not a fact. We have no idea how large/small the universe is, if it's infinite or if it's still expanding.

As soon as nothing 'appeared' from well, nothing, which would be something if its come from nothing, hich is already something as it would've already exsisted in time and space. If its infinite,

Like I said, it's commony accepted that before the big bang, everything (meaning energy), was stored in a single point of singularity. Not nothing. (Single-negative)

Nothing is fact. The laws of physics are only a theory, it's only a theory that you exist, everything that has not been proven wrong is a theory. Many people claim to have scientific theories, a theory has to be proven correct. That means that not only can you give evidence of it, that evidence cannot be proven wrong. As such, every accepted theory can be relied upon to be accurate.

Much like the theory of evolution, it has many gaps and inconsistencies, that´s why I don´t thrust this type of theories, because they are incomplete.

What gaps does Evolution have? It essentially says that after life was created (it doesn't say how life was created) animals changed and adapted to fit their role better. Sharks, over time, developed better organs for hunting in water, birds developed better ways to fly etc. What hole is there in that? As for the big bang, it's simple. It says that since the universe is expanding (This is proven) if you simply 'roll back' the clock far enough the universe occupies a point smaller then the head of a pin, from which it expands. Where is the hole in that?

I'd say you're partially right. I don't know enough to say if space is curved or not, but if we assume that it's flat, then yes, the universe is infinite, but the part of it with matter in it is finite. If light started moving away from the centre of the universe as soon as the big bang happened (13.7 billion years ago), then the part of the universe with light in it is 13.7 billion lightyears across. 1 lightyear = 9.4605284 × 10^12 kilometres, so the part of the universe with light in it has a radius of 64 804 619 540 000 000 000 000km, or (40,267,723,690,676,291,680,000 miles). Beyond that is nothing, no light, no matter, no energy, nothing.

So you are partially right, the universe probably is endless, and expanding, but we do know how it started, and so we can figure out how much of it has 'stuff' in it.

How was that proven? I know that there is evidence (i.e. everything in space moving 'outwards'), but when was it proven as fact?
If it was proven that the universe is expanding than why are so many people asking if the universe is infinite?

How can the universe end? The very word means "everything." Anything that exists beyond the universe would have to be somewhere else, and every thing that is somewhere is part of everything. That's a mouthful.

Ack, damn. >.<

The 'Universe' mean's 'everything in existance', so it depends on how you define 'nothing', seeing as there's 'nothing' outside the universe. But what confuses me is how a multiverse (a theory that there is more than one universe) is possible, because wouldn't they all just be within the universe? In that case what's the definition of universe?

Well, it's not fact, nothing is.

Anyways, I'm afraid I'm not an expert on the big bang, but just looking at it logically, if the universe is expanding, then at some point it must have been smaller then it is now, one second ago it was 1 light-second smaller then it is now, one year ago it was one light-year smaller etc. So, if you carry that back 13.7 billion years you get it being 13.7 billion lightyears smaller then it is now, or, smaller then the head of a pin.

Also, the universe can be infinite, it's only the matter in it that is expanding.
