please tell me something about the word Universe?

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

you should read more into string theroy and the M theory.  they are both very interesting.  it is hard to wrap your mind around but  this is just one universe that goes along a membrane of universes that goes on infinetely.  the science channel often has show that explin all this much better and they make it pretty easy to understand.

its actualy String-theory that proposes the existance of many other universes. the theory proposes a so called "Landscape of probabilities" with probabilities of as many as 10 to power of 500 universes, and with that many probabilities it is very likely that some of them will be similar to or just like our own universe.\n\nif you would like to know more about this facsinating subject, i would suggest this book http://www.amazon.com/gp/product/0316155799/104-3626905-5554311?v=glance&n=283155\nits a great and easy to understand book.

I read in Time a few years back that in an article, scientists explained a theory that universes connect as a chain, and our Universe- is among many. The idea was quite something to read and of course the diagrams and images they used to portray this thing out was all very fascinating to say the least. It was a rational idea even to me and considering what we found with a pin tip portion of the night sky magnified 1,300 times....hundreds of thousands of Galaxy's all clustered in an array that almost seemed like you are looking at it all through a cylinder. \nSo there is no real way to know for certain, but there could be millions of them...and a chain of universes makes rational sense.

Well, if you want to break it down even more, the universe only consists of minscule, vibrating strings.  At least, that's the most widely accepted theory in fundamental physics right now.\n\nThe beauty of it all is how much complexity can arise from such simple fundamentals.

When talking about the universe, asking "why" something is the way it is usually has no absolute, 100% answer.\nThe best answer to your question is that the universe somehow began over 13.7-billion years ago and immediately began expanding. The expansion has gone on, steadily increasing the size of the cosmos until we observe its vastness today.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

OK, this is the Physics section, but your question is more a philosophical one, so let me try to answer in a philosophical way. Every time we speak about "the universe" we are easily engulfed into paradoxes, because the subject itself is ill-defined. You can't apply to the whole universe concepts and procedures that are defined and thus applicable only *inside* it. Like "measure", "big" and "small".\nAs the great Argentinian author Jorge Luis Borges once wrote, "There is no classification of the universe not being arbitrary and conjectural. The reason is that we do not know what the universe is".

Nothingness.\n\nOr maybe it's encroaching on another Universe?  Hmmmm......

physically the universe has no limits . but still it is expanding with enormous speed . you can go to this link : http://en.wikipedia.org/wiki/Space and find out whatever you need about space . good luck

There is an end to this universe.  But, it is constantly expanding and contracting.  Empty space is what lies outside of it.  The universe is encroaching into empty space.

God created the universe. Notice how the word universe is Latin for "single spoken sentence", which is how he created it. God spoke everything into existance e/accept man, who he created with his own hand. If you dissagree, my username is my e-mail.

Big Bang theory \n\nIn astronomy, a theory according to which the universe began billions of years ago in a single event, similar to an explosion. There is evidence for the Big Bang theory in the observed red shift of distant galaxies, which indicates that they are moving away from the Earth, in the existence of cosmic microwave background, and from other data. The Big Bang theory of the origin of the universe is accepted by most astronomers today. \n\n\nScientists have recently found that the expansion of the universe is actually speeding up. This effect is attributed to the presence of dark energy.

I like physics. thats how the universe is formed. it is god languge. Most physicist got to know god and his wonders through physics.Physics is the language of the universe. Aliens if there is any can understand physics. Maths is the mother of physics.

There is no proof that our universe is, was or will be the only universe.  The nature of reality is that we can only study and observe what is in our universe, so we will never know because there is no way to find out.

I think the Big Bang is actually another universe budding off. There were mulitple Universes (Parralel Universe Theory) before the big Bang. Yet, what do u define as a universe? If it is a "world" of intelligent being maybe not (who knows). So the answer is yes and no depending on ur definiton of a universe.

A parallel universe is one of an infinite number of universes that is defined by the set of every decision ever made within it, which means everytime anything is presented with multiple courses of action, a new universe is created for every possibility. These universes will never intersect (thus, "parallel")\n\nEvery universe (in theory) has nine different dimensions (I believe there are four of space and five of time). Four of them (three of space, one of time) are tangible to us. The rest are seemingly intangible to us, but they still affect us. Kind of like how a harp string is realyy thin and hard to see, but you can hear its vibrations. I'm not really an expert on quantum string theory, though, so this is a really simple explanation (believe it or not). You may want to look more into that. \n\nOr, you might not care.
