What Is Beyond The Universe?

The though of what might be outside of our Universe has been on my mind a lot lately. I'd like to know what you all think is outside the "borders" of our Universe.

1) Where is our Universe in relation to anything else? (i.e. if the Universe was a dot on a piece of paper... what could be outside of that dot)

2) How did the Universe form? (where did everything originate from, what set everything into motion)

3) Some scientists say that beyond the Universe is "nothing" (black and 0 degree temp), but isn't "nothing" still something?...

4) If there is nothing beyond the Universe, then "nothing" is occupying space. The concept of space is in fact something, isn't it?

5) What force would possibly define the borders of whatever is beyond the Universe?

I'm sure these questions might sound a bit odd, but I'd appreciate some input.

These are the questions that Stephen Hawking himself really couldn't give you an answer to. I like to try to think that if the Universe is finite, there are either more of them or something larger outside, or alternatively there is no outside of the universe, and perhaps existence itself is finite. But that might also be my trying to reconcile the idea of infinity which is truly incomprehensible, you can spend hours just pondering this question and only end up with more questions.

My (uneducated) answers:

1) Is a meaningless question since the Universe is homogenous. There is no special vantage point, by definition, the Universe is all there is, so it simply doesn't exist in relation to anything else. (unless you espouse the many-worlds interpretation perhaps).

2) An infinitesmally, small, hot, dense, singularity. Beyond that, I have no idea - after a bottle of whisky, I might have a better answer.

3) Yes.

4) No, nothing is "occupying" space - the fabric of space is stretching - hence why the galaxies are moving away from us at millions and millions of miles an hour. The galaxies are not rushing off into "nothing" since it is the space *itself* that is being stretched. Pretty much like you would stretch a piece of rubber.

5) I don't think there are any "borders" - based on what we currently know, there are three possible shapes for the Universe (i) positive curvature (i.e. spherical) (ii) negative curvature (i.e. saddle shaped) and (iii) flat. A 3-d version of these possible shapes that do not have borders is called, I think, a 3-d torus; that is, when you reach the "edge" you simply emerge on the other side. So space wraps around pretty much like when you're playing pacman and when he goes off the screen he re-emerges on the opposite side of the screen.

Well, that's not very enlightening is it - I recommend the bottle of whisky if you're going to spend time contemplating the origins and nature of the Universe.

Oooh - zen !

Apparently beyond our universe, seperated by the thinnest of all possible barriers, is an alternative universe. This explains gravity. Or explains it to SOME people anyway. I watched a very interesting documentary about it on the BBC, about 98.7% of which went straight over my head.

Yes my take on these questions: (and purely that since all I posses is the information provided to me via the information system we revel in and hence I am already biased to the degree of the information provided to me)

Quoting TUNisia (Thread starter):
1) Where is our Universe in relation to anything else? (i.e. if the Universe was a dot on a piece of paper... what could be outside of that dot)

Why does it have to be a piece of paper? Here is my meaning - if the universe is finite (and it is my belief that it is even though its expansion may be infinite) then why limit it to a piece of paper (i.e. a map) when really it may be a very complex or highly simple 'ball' if you will. If you are to take the big bang theory, you may draw the conclusion that as the forces of the bang are equal and opposite in all directions then the three-dimensional 'bubble' created will be equal the whole entire way around, yet even the smallest inconsistency may vary this on a magnificent scale to great to be measured.

Quoting TUNisia (Thread starter):
2) How did the Universe form? (where did everything originate from, what set everything into motion)

If someone were to know the truth to this, they most certainly would not be an a.net member, yet my belief is that in the pre-universal era, there were simple concentrations of elements within "space" which collided, and generated tremendous energy in turn leading to what is known as the big bang theory. Everything that we know to exist is formed from this, including life itself. Evolution took that very basic single cell life and over a vast time scale (what is thought to be a bit over 4 billion years) evolved into the complex multi-cell organisms of today.

Quoting TUNisia (Thread starter):
3) Some scientists say that beyond the Universe is "nothing" (black and 0 degree temp), but isn't "nothing" still something?...

Nothing could be simple a "vaccum" of spacial atmosphere. (i.e. an area with no mass and not possesing any trace of elemental material or matter at all. This is what we know true space to exist of, yet it begs the question as to what is on the outer bounds of this big expanding 'bubble'. That may be the same (a matterless vaccum) or just a void beyond our current comprehension.

Quoting TUNisia (Thread starter):
4) If there is nothing beyond the Universe, then "nothing" is occupying space. The concept of space is in fact something, isn't it?

As I just addressed, what we know to be on the outer bounds (or outside the layer) of our expanding universe is something which may yet be beyond our comprehension. It may be something like anti-matter (although most scientists regard this not to be the case) or it may be as simple as the spacial voids we know to exist already.

Quoting TUNisia (Thread starter):
5) What force would possibly define the borders of whatever is beyond the Universe?

Are these borders defined as you suggest, or are they forever expanding in the frictionless atmosphere of space? Many people will believe now that universal expansion is coming to a halt, and in grand time scales will collapse back in on itself. If this belief is true then is it not possible that elsewhere within that void the same thing may be occuring on an infinite level? I believe that to be true yet how will we ever prove that to be the case?

You have me thinking tonight!

Cheers.

Actually that has been relatively disproven due to the expansion measurements with the big bang theory so I understand. You'd need someone with a greater knowledge than me to tell you the actual reason, its just what I read in an interview transcript.

I thought the prevailing theory is that there are indeed other universes. The term cosmos is the one used to capture the idea of everything that exists anywhere.

As for the notion of parallel universes, is there any chance that somewhere there's a universe in which beer, wine, cheese, chocolate, whipped cream, iced cream, and all those things that I'd actually like to consume with every meal are indeed health foods?

It's a popular line of thought (David Deutch's 'Fabric of Reality' goes into some detail about the many-worlds hypothesis), but it has the consequence of unecessarily bloating ones ontology. The price of explaining certain phenomena is to make the theory infinitely more complicated.

If by other Universes we're talking about the idea that there may be as many as 11 (quantum) dimensions hidden from view which is what String Theory says, then that view has some currency.

Another idea is that if we trace the Big Bang right back to the beginning, then another 'inside-out' Universe will be on the other side of the singularity.

The so-called underdetermination of evidence, since there are a number of theories that are to some extent, compatible with observable data.

I don't favour the many-worlds interpretation for the reason stated - it has the consequence of complicating things enormously.

But what is our Universe expanding/stretching into when it expands? Is the Universe subject to gravity from an outside source (like the Earth is subject to the gravity of the Sun)? This is totally the wrong place to ask these questions, but they are drivng me almost crazy.

Thanks for all the responses thus far!

Please please *PLEASE* stop using the term "expanding" when talking about the universe!!!

Here's why: The universe is infinite, right? So, how can something be "expanding" in infinitiy? Where is the center of infinity? Where is the edge of infinity? I agree the universe is moving and shifting. But, for something to expand, it must have a center.

To expand further on the original topic, many decades ago, we belived the atom was the smallest thing out there. Then, we discoverd there is stuff inside an atom. Hence, there could be a billion universes passing in front of our eyes as you read this post. There could be trillions upon trillions of life forms that we will never be able to comprehend passing right by us at this very second pondering these same questions. Are we the largest entity here? I believe we are not. Are we the smallest? I believe we are not. Our concept of time is relevant to only us on this planet. It means nothing to those worlds being created and destroyed every time we blink. We could simply be a drop of water in a petri dish in some laboratory and will never know.

Having an alternative universes pass through me would certainly explain why I get these odd itching sensations and twitches periodically....

How does one define 'universe?' I'd guess one would include anything of mass or energy, but might one also include the space in which it exists? Or could potentially exist? While we might be able to define the current borders of mass and energy, it seems to me that this space could be infinite.

I've read that the universe lacks sufficient mass and subsequent attractive forces to counter expansion and cause contraction. Thus, any theory of an oscillating universe would require additional forces which are currently unknown to man.

There is also a theory that states that expansion is actually accelerating.

I think it is remarkable that we can even conceive of infinity, though I know that I can fully grasp the concept.

No. There isn't any "special" location in the Universe - it is homogenous wherever you are. I know it's the natural, intuitive picture we have in our heads of a tiny singularity rapidly inflating to create the Universe we currently observe, but there is no "center", no point you will arrive at by hitting the "rewind" button.

Time is also relevant everywhere - we can be pretty sure a clock in a galaxy 10 billion light years away would tick away at the same rate due to very, very probable physical laws. The symmetry of the Universe pretty much proves this.

I don't claim to be able to wrap my head around it - the Universe is a pretty strange place  Smile

Yup. And the furthest galaxies could be accelerating faster than the speed of light; the reason this doesn't violate Einstein's special relativity is the acceleration is the expansion of space *itself.* I'm too tired to type out the details, but I understand this to be the gist of it - surely somebody around here can explain it more coherently.

I find it a little depressing .... it will probably expand and expand, the cool down even more; it'll be dark, depressing and empty with nobody left around to observe anything. Pretty optimistic view eh.

I took an Astronomy class in college and the very first video we watched in class contained one of the most fascinating things I have seen. This is going to be really hard to explain without you seeing the video Im talking about, but here's a try. Beginning with the atom, the opening sequence zooms out, and out, and out...basically from the smallest thing we know out to the universe. So it went from inside the atom, to the atom, to the molecule, to matter, to an object, to a house, to a city, to our planet, to our solar system, to our glaxy and so on. I cut come corners there but yeah, you get the idea. But what it really showed was how from the atom to the universe, the general appearance is the same along with various stages along the way. It was a cycle through similar repeating stages that had similar characterisitcs.

I have never liked the idea that everything in the universe has to have a beginning somewhere. That there HAS to be an explanation of how it became what it is. Why can't it, just be. Does the fact that because we, as living beings, have a begninng and and end automatically mean the same for the universe? We ask questions about the origin of our solar system. How was it created? We ask about our moon. Where the heck did it come from? Who says it had to come from somewhere? Who said our solar system had to be created in a step by step logical sence, if created at all?? Why can't it just be what it is, possibly since the beginning of time...oh wait...i said beginning of time. Why does there have to be a beginning of time?? This can lead to personal and religious beliefs and can get messy. I have my own beliefs as well. But sometimes you have to exit certain contexts and just think...outside the box, starting with, there has to be an explanation for everything.

These are the things I like to think about. If there's one thing I learned about taking an astronomy class, even though I am absolutely fascinated with the subject, I am frustrated and annoyed that all learning about this stuff does is create more questions. Questions that we will never know.

One thing I think would be really cool is, when you die, all questions you have that will never be answered in this lifetime, will be answered.

No, just because there are no finite bounds for measurement it does not mean we are unable to tell that the universe is expanding. For instance, the current way they deduced the expansion theory is by measuring the echo left by the explosion of the big bang. Although far from being a certainty, scientists are able to deduce from the frequency of the sound waves that the universe is increasing size in all directions from the echo of that sound. Now universally, there is a centroid, but a clearly defined centre would not exist because of the universe's imperfect shape.

Stephen Hawking suggest that the Universe is actually slowing down and will eventually collapse on itself. As for the moment, it seems as though it is expanding, but I concur with several of you when you say that objects can't be expanding in an infinite space. At times I often question that the Universe is actually relative to human thought. What we think as the end, is the end of the universe. It's a way of making the universe relative to human thought. However, as the human mind allows for greater boundaries, the universe becomes exponentially expansive. Boundaries are only determined by human boundaries. When we can think outside our own paradigms, the universe opens up even more. The universe is as large as our human mental capabilities.

Seems far out, but humans seem to only be able to define what they see as reality. Things out of reality are often pushed aside as "faith." Which I think is part of the development of religion.
