administrator Posted April 28, 2003 Report Posted April 28, 2003 Is there anything beyond our universe? Exactly what is our universe housed in? - more space? AmanShah 1
administrator Posted May 2, 2003 Author Report Posted May 2, 2003 i know isnt it just the most annoying question!!!!!
administrator Posted May 4, 2003 Author Report Posted May 4, 2003 I believe it is possible that there is nothing beyond our universe and the expansion of our universe is simply the creation of more space, space that will simply be a part of this universe. But yet, this concept is mind bending. Does the universe need more space? Possibly its all the same space, but unoccupied and nothing is outside the universe, simply a figment of more space which we have concocked in our minds to explain what we are expanding into.
Tormod Posted May 5, 2003 Report Posted May 5, 2003 This really depends on what you define as the "universe". If you are talking about the Observable Universe, then it simply expands into more of the same (more stars, more galaxies) - because it is defined by the distance of the most remote light we can see (imagine a sphere with a radius of some 13,7 billion years). If you define the "universe" as everything that can possibly be, then there is nothing into which the Universe can expand. This would make the Universe infinite (but not necessarily occupying an infinite space - simply all the space that is available!). Another way to view our Universe is to consider that it might be a part of a larger universe in which ours is only a small part (like an island in the ocean). This is actually just a modification of the first point above. However, depending on how each of the universes came into being, their physical laws and properties may be different. According to the Anthropic principle, we live in the most likely of all universes. This principle in fact requires there to be an endless amount of possible universes, some of which must exist "out there". Anyway, we have covered this before in our forums so try to look back through the posts and you might find some interesting points. Tormod
cern Posted May 8, 2003 Report Posted May 8, 2003 The answer is that there is no outside matter or space, we are contained within a small bubble that is expanding spacially for us but not actually taking the space away from anywhere else.letucre slides on the bigbang theory. large file about 2.1mb
Tormod Posted May 8, 2003 Report Posted May 8, 2003 cern, that is only one theory among many - and it is becoming rather outdated now. To view the Universe as a bubble is in fact a very simplified way to see it. It is easy to argue that the _observable_ Universe has the shape of a sphere (because we find ourselves in the middle of it, and can see equally far in each direction in spatial 3D) - but you cannot from that simply conclude that the entire Universe has a spherical shape. Here's a simple MIT Cosmology Faq which addresses the very question which started this thread. Tormod
Oracle Posted May 20, 2003 Report Posted May 20, 2003 Why big Bang there's a bang after bang ....explosion after explosion but what my "incredible, ubelievable" SPONTANEOUS brain has come up is this: Imagine a bubble gum, you blow the bubble there's all the galaxies in it everything its the universe, it pops up (BANG) and galaxies and everything spread even more and create a new bubble gum bars which will expand more and more at the end there won't be any gum left so it has to be "chewed" all over and blown up again.Tormod, I think I'm getting into a concept of the theory you mentioned in the General Discussion about the " universe recreating itself" .. just maybe going back in time sounds too unbelieveable for such an enormous energy.
Tormod Posted May 20, 2003 Report Posted May 20, 2003 Did you drink too much bubbly last night? ;) If we accept a theory of a never-ending series of Big Bangs, I think it follows that the Universe must be infinite. It would be difficult to find out which bubble was the "first" or "original" bubble, so for all practical purposes the Universe would be like an infinite onion... The concept about the Universe creating itself comes from J. Richard Gott III's book "Time Travel in Einstein's Universe" - a highly speculative book. It's not my idea. B) And frankly, I wouldn't give it good odds. Tormod
Oracle Posted May 20, 2003 Report Posted May 20, 2003 Ha you're right I just hate the chicken and the egg question though imagine if we knew for certain what came first-alot of things would get clear :-P
necron Posted October 12, 2003 Report Posted October 12, 2003 It is very simple. the egg came first. Chickens evolved from reptiles, right? So something that was almost a chicken must have laid a chicken egg. Understand? I know this can mean different things when used in different contexts, but what is there outside of our universe? Is the universe infinite? Or is there an infinite amount of universes? Or is there an infinite amount of infinite universes? I'm going to shut up now because i'm starting to confuse myself
Anomaly Posted October 29, 2003 Report Posted October 29, 2003 if there's one universe, why not more?
Tormod Posted October 29, 2003 Report Posted October 29, 2003 Welcome, Anomaly! Yes, why not, indeed. The theory of the multiverse is very much alive in cosmology. Britain's Astronomer Royal Martin Rees has written about this in his book "Before the Beginning - Our Universe and Others". It's a great idea (but hardly provable). Tormod
deamonstar Posted October 31, 2003 Report Posted October 31, 2003 or perhaps more importantly... cannot be UNproven!
the transient Posted October 31, 2003 Report Posted October 31, 2003 The multiverse idea, chaos fractals, and the holographic hypothesis are all attempts at explaining that there can be "no-thing" outside our universe, and that the term universe is as outdated as thinking that Heaven lay outside our solar system, it is merely a convenient term used to describe our localized perception of phenomena. Linear into non-linear.
Dent Posted November 5, 2003 Report Posted November 5, 2003 Beyond the event horizon could lay naked singularities which collapse when the possibility that light will reach that point , in potential space time , and those that remain and dont collapse are there for potential dimensional improvements to our allready traversed universe ...... this potential for more space could be infinate or untill all naked singularitys outside the event horizon are consumed.
Terminus Posted November 6, 2003 Report Posted November 6, 2003 I don't think that anyone here can answer your question. Even if the universe is "infinite", it would still have to be contained by something or expand into something. I don't think our feeble little human brains can comprehend anything like this.
jizum3434 Posted December 23, 2004 Report Posted December 23, 2004 haha havent u ever seen men in black! were in a big marble! hah no i dont think its possible to know something like that. maybe its full of jello or something
