I think in universe can exist everything what we think,dream,there can be many other time zones,dimensions,there can be other lifes in other dimensions we dont know,but its all possible? are we people big players in all of this? without us universe can exist?

I agree. Every single emotion; every single scenario imaginable; both sides of the extreme and what lies in between will occur in this universe. In my opinion, anything is possible in this universe…ANYTHING! And I don’t think this universe has meaning without human ‘observation / awareness’ (consult ‘the observer effect’ in quantum physics + my question about the sound of tree falling in the forest).

Anything is possible "if" another impossible thing is found to be possible; so long as the original thing is made possible by the formerly impossible thing.\n\nIn other words, of course time travel is possible so long as other impossible things become possible that would make it possible, such as your catalyst which would open a space and time rift.\n\nTherefore, the real question is not whether time travel is possible, but whether any catalyst does exist that would make it possible.\n\nThanks for the post!

Yes, I think it is possible.  We live in such a great universe and there is probably another life form out there.

Is our universe in another universe?  \n\nBefore we can address that question, we must first define universe.  \n\nThe word universe denotes all space and everything (matter, energy) contained within it.  The prefix uni means one.  The root verse means word, carnate message, meaningful substance, matter.  Questions regarding our universe persist today.  Does it have a beginning and end, or does it go on forever and ever?  Is it linear or curved?  If it has limits of length or curvature, then what lies beyond the Universe?  If something lies beyond the Universe, then can’t we accurately call that the Universe?\n\nSome lay people and some scientists conceive of the universe as infinite space.  Others define the universe as finite, or limited (perhaps curved), space.  Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.\n\nGiven these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”  \n\nAs to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “\nAndromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”\n\nIn accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another.  Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.\n\nSome string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe.  Our zone, a “braneworld” could periodically bounce into another parallel braneworld.  This may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective.  Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.\n\nIs our universe inside another universe?  Well, apparently the Men in Black had it right.  Our universe seems to be inside of something else, another universe, called the multiverse.\n\nSteve\n:-D

The current theories have predicted how large spacetime is, and many Astrophysicists are now working on finding who is beyond our universe. \n\nSo no, space is not infinite in the sense that most people think of. Outside of our universe is still a mystery, but keep in mind that there is not three demensional space outside of our universe, and no time, either.

A very thoughtful question.\n  I think that in the normal sense of a parallel universe it can not be.\n  I do agree that every entity in the universe is isolated in time  as a zero time point and in effect could be deemed to be in a parallel universe.\n  I guess it may be a matter of definition.

There have to be some where, with such a large universe and completely undiscovered yet the probability is very very high of life somewhere else in the universe. It just diminishes when we think about intelligent life forms.

First there was me, then I spake and there was the word, the word was light, and behold there was light.... Things got a lil complicated after that (won't bore you with the details), took me quite sometime to get it all right, in fact I'm still having trouble with those pesky humans, they were a mistake you know!... Well no one's infallible!\n\nWell to answer the other part of your question, there was only 'nothing' in the way that you understand it, there are dimensions upon dimensions, which make up the whole, the 'nothing' that is in one dimension is energy in another, time in another.  What you do is you focus your id onto the 'nothing' that is elsewhere and form the thought, the thought then becomes a word, and the word becomes every thing... Oops I think I might have just said too much.... Please don't tell anyone else.\n\nPS. All laws of nature that exist are only relevant in this universe/dimension, and only to those who are not aware of the other dimensions.

Watch NOVA on public television or science channel. There was an episode about string theory.\n\nIt's scientifically possible to explain other dimentions. Therefore, perhaps, we leave this world and go to another when we die! perhaps ghosts are just people trapped between dimensions.

i don't think in terms of the universe being massive compared to the size of galaxies,but minuscule compared to that which is outside the universe, that way there is an endless supply of material on hand.here at the"center of the universe"it's all relative to our thinking everything is so large but since all we can do is theorize about whats out there,why cant we theorize outside the box,way outside the box. where did science get this idea ? i believe that a chaotic set of galaxies brings about an ordered universe that is a single organism of a larger set of chaotic universes,which in turn forms ordered groups of galactic multiverses which is a small component of a megaverse ,and so on

beleive all is possible! The mind is very powerful! It can be good or bad! It's all what u make of it! It is a form of religion(believing in what is seen and felt)they cant be judged,as noone should!\nBut yes i believe they exist,they are spiritual people,they just chose odd ways to do so,that other's dont understand! Most fear it, cause they dont understand it,or they chose not too!\n I practice their beliefs, we are not worshipers of satan(but there are some who do,but we can tell who they are!)\n Live life your way,and how you see fit,cause no matter what you believe in, someday we will all sit at the judgement table together!!

it's a hard question to answer, cuz same as you can't be certain they don't exist, you really can't know for sure if they do !! Although I can't say they exist ... i don't really see it impossible ... they "might" exist ;)

In spite of what some yo-yo answered, the universe IS expanding, but whether or not it's expanding inside something else is absolutely and totally unknown. In the far distant future our science might have progressed to a point where we'll have the means to answer that question. Instead of driving yourself goofy over wondering what our universe is inside of, best to just try and imagine an absolute and infinite void totally without space, time, energy, mass, or anything else.

There are _trillions_ of stars in the Universe.  Our galaxy, the Milky Way, is composed of 300 - 400 billion stars.  There are _billions_ of galaxies in the Universe, many dwarfing the size of ours.\n\nThe chance of other life _not_ being out there is so close to zero that it can't even be calculated.  There are infinite possibilities in this Universe, and we haven't begun to study more than a tiny bit of them.\n\nTo anybody that has the audacity to say "no" there isn't, then get an ego check.  We aren't the only intelligent life in a Universe of infinite possibilities.

of course it is theoretical. It is like my answer to another question, what contains the Multiverse? "What's after that?" I had said. It is theoretical and we like to think that the universe has a finite space and something holds our universe with another finite space. We like to think this way because that's the extent of our view and understanding. We live in the 3rd dimension and we can only understand physical things in the third-dimension. We can only have so much understanding on our universe that everything about it has to be based on theories. Even the fact that the 4th dimension is time is not really a fact, but still a theory because we can't think in that dimension. We haven't been through the 4th dimension (i know the theory is that we're going through it in one direction but it still is a theory). Our understanding of our own universe is very limited because we live in a finite world.\n\nAnd it doesn't answer your question, i know. But I like to think of the multiple universes that you're talking about as the Alternate Universe theory where something doesn't happen in this Universe, it happens in another and if it is this case, there is almost infinite number of them. And the wormhole thing works with Einstein's theory of Relativity as a Super Massive Black Hole is strong enough that it bends the space-time continuum so much that it will make an advanced dimensional hole in another (if not all) universe. I devised an un supported theory that that hole created by the black hole is actually a 6th dimension because it disappears as matter from the universe then exist in another. A total violation of the law conservation of matter unless it actually goes through a wormhole, which would go with the theory of relativity AND conserves matter. But it still is a theory that I accept.\n\nPS Penguins!!!

I believe there's other dimensions but I have no proof of this myself. \n\nIf having dreams that sometimes come true is a paranormal ability, then I have one and I've also witnessed other paranormal phenomena first hand, so I believe in that sort of thing.

The above answers are interesting but, modern physicists speak extensively about 'multiverses'.  So, does one universe end at the edge of another? or, do they 'co-exist' in space and time? OR??????
