The holographic model of the universe: The universe consists of information which is projected in it's manifestation.\n\nComputers are a good example of this. All of the information on your computer...or most of it, is stored as 0's and 1's in the form of magnetic clusters on magnetic plates.\n\nBut, YOU see this message and websites and pictures of Angelina and Brad's baby. You experience 3D games with music and walk your character through hallways where nothing really does exist on the other side of that wall because it is just a projection of information stored elsehwere...and maybe the information for something on the other side of that wall doesn't exist.

No.\nThe Universe is a physical object.  It has a definite size and shape.  The Universe is so big that we do not know its limits.  Our ability to comprehend is not the problem, our technology is.  If we had the right equipment, we could see to the end of the Universe and mesure its size and shape.

The universe is an indefinite entity.It is bounded by 'nothing' even in the strict sense of modern physics.

The size of the universe in terms of length, width, height, time is in a state of flux. At any instant it may be expanding or contracting. The universe is generally accepted to be currently expanding. \n\nM Theory (the conglomeration of the 5 superstring theories) tells us that the universe is the result of, so called, “membranes” colliding in such a way that create a pocket of space which we call the universe. If M Theory is accurate, it is probable that there are many universes just as there are many planets, solar systems, and galaxies. \n\nFor more information:\nhttp://en.wikipedia.org/wiki/M_theory

The universe is everything that exists.  The opposite would be everything that doens't exist.  So, the opposite is nothing.

The Universe is thought to be 'finite but bounded'. That is, it does not come to an end anywhere but somehow loops around again far, far away. Another example of a finite but bounded shape is the surface of a bubble, a sphere. It has definite area and size but there are no edges to its surface, no place to call a "beginning" or "end" that is not arbitrary.

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.

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

1.Steady State Theory-According to this theory,as old galaxies move apart new galaxies are being formed in their space.\n2.Pulsating Universe-According to this,universe contracts and expands alternately.A great explosion occurred in the universe and it has been expanding since then.After some time gravitation would halt further expansion.After that all matter will begin to collapse upon itself and the process will be repeated. \n\n   However the most probable theory is the Big Bang.

Would you like to see a real picture that was recently made of the beginning of the Universe?\n\nhttp://www.princeton.edu/pr/pwb/03/0217/

That's a tough one.\n\nI like this approach: \n\n"This question is based on the ever popular misconception that the\nUniverse is some curved object embedded in a higher dimensional space,\nand that the Universe is expanding into this space.  This\nmisconception is probably fostered by the balloon analogy that shows a\n2-D spherical model of the Universe expanding in a 3-D space.\n\nWhile it is possible to think of the Universe this way, it is not\nnecessary, and---more importantly---there is nothing whatsoever that\nwe have measured or can measure that will show us anything about the\nlarger space.  Everything that we measure is within the Universe, and\nwe see no edge or boundary or center of expansion.  Thus the Universe\nis not expanding into anything that we can see, and this is not a\nprofitable thing to think about.  Just as Dali's Crucifixion is just a\n2-D picture of a 3-D object that represents the surface of a 4-D cube,\nremember that the balloon analogy is just a 2-D picture of a 3-D\nsituation that is supposed to help you think about a curved 3-D space,\nbut it does not mean that there is really a 4-D space that the\nUniverse is expanding into."\n\nAlso, read the wikipedia article!

the boundaries of the universe are a snow-globe. we exist in the snow globe of something much larger then ourselves. the stars are just the pieces of glitter that float when you shake it and then fall. the billions of years in our universe is just a few seconds in the life of someone who shook it up and now watches the snow fall.

this is actually a common misconception about the big bang.  the universe may be something like the two dimensional surface of a sphere.  it is finite yet has no boundary and no center.  nothing exists "outside" the universe.  to quote a dead writer, "there is no there, there".\n\nread this:\nhttp://www.sciam.com/print_version.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147

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

How do you define what a universe is?  I define the universe as everything there is.  Obviously the set containing everything does not allow the existence of something outside of it.  In other words, if you were to show me evidence of another universe I would say that what you have shown me is part of this universe.\n\nBy my definition there can only be one universe.  Do you have a different definition of what a universe is?

In materialist philosophical terms, the total universe is the summation of all matter that exists and the space in which all events occur. In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist. It has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse. It is a period of space, including not only the 3 dimensions we know, but up to ....... TRILLIONS we don't know. TIME EXISTS EVERYWHERE??? Or no... Answer: 88% NOT EVERYWHERE
