What is outside the Universe?

Some astrophysicists believe in the 'Big Bang.' Others believe in 'Condensation.' But whatever happened in the beginning, it proceeded according to two things that must have existed before the Big Bang or Condensation. These are:\n1. Time\n2. Gravity\nEven though our little human minds can not conceive of it, the Universe might actually be 'infinite.' Consider this little fact... light from the farthest galaxies that we can detect as been traveling toward us for billions of years. That means that light has been going in the other direction as well for billions of years. \n\nHumans always want to put themselves in the center, as if all the distant galaxies were somehow in a sphere with Earth, or at least the Milky Way, at the center. Just because we can not see anything farther away than those distant galaxies, we tend to say that there is nothing beyond them. \n\nBut, billions of light years beyond them some fools are saying that since they can't see us, billions of light years beyond those galaxies on THIS side, that those galaxies are at the edge of the Universe, and there is nothing beyond them. And when they look in the OTHER direction, they see galaxies billions of light years away. And on the other side of THOSE galaxies, there are some fools saying...

I don't know.  But it would seem to be something not of this Earth.  I'd be interested to find out someday though.

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?

Before 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 “\n\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/U... 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. \n\nThis 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\nWhich is the end of expanding universe? That may be determined in 300 billion years, when it stops expanding (like a balloon). If any end exists, what will be behind this end? A multiverse void containing other expanding and contracting balloons, referred to as universes, may exist beyond our own.

Recently, scientists are creating theories that saying there are more universes beyond our own. Until we learn to harnass the power of warpholes, black holes, etc. or send things traveling at the speed of light without damaging it, we may never know where space ends.

you mean extra-terrestrial?

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

In an extention of the big bang theory, the size of the spots in the microwave background radiation can indicate the geometry of the universe. Recent (2001) measurements confirm that the universe is "flat" (for an explanation of shapes, see source link). There is a 2% margin of error in this measurement.\n\nAs for what is beyond space, I would say the question isn't possible to answer, as most people define "space" to mean "Everything there is". What is outside of "everything"? Nothing, it would seem.

Within this universe, no.  There is nothing outside our universe.  To get somewhere else you have to leave our dimension, that’s where the other possible universes lie.  Is God bigger than our universe?  He created it, and has complete power over it.  However, He is in no created dimension, which is how He can affect any dimension.  He is bigger than any universe, if they exist, He created them.  So is there any created place bigger than the universe?  I don’t know, maybe.

The last response made a good point.  Science only seeks to answer certain questions.  What exists "outside" the universe? What existed before the Big Bang?  These are questions that scientists currently are not seeking.  That question is left up to the philosophers for now.  \n\nThe questions really point to a better understand of the universe and whether that question is important, relevant or even consistent with our present knowledge of the universe.  \n\nAstronomers and physicists find the surface of an expanding balloon a good analogy for the nature of our universe.  The surface, just surface mind you, of that balloon has no center or edge to it.  Just like how we understand the universe.  The surface material of the balloon would be what we call space-time.  \n\nWhat is outside the surface of the balloon?  Well there is no balloon material outside so it is not space as we know it but one perspective says it is a future balloon surface.  Just like inside the balloon was once a past balloon surface.  \n\nThe universe could have a similar analogy.

Outer space is not nothing. Even without the presence of matter, it is teeming with quantum foam, particle-antiparticle pairs, space, and time. For all we know, spacetime may not exist outside our universe."\nAlso, the universe may not be bounded. The only way to "exit" may be to find a "fourth direction". Ie., think of a point in an unbounded plane. The only way for the point to exit its universe is to somehow find the "third direction".

Our solar system is not the only solar system in the universe.  There are hundreds and thousands and millions of other planets in the universe, and many are just like ours, but we don't know about them because we have never been able to get anything further than pluto to get a good specific picture of stuff.  In a general picture, though, we do know there are other galaxies in the universe

Surely you know the proponants do not have an answer. On the same note, neither can anyone answer (yet) what was there before Big Bang?

This sort of question generates the highest percentage of false and meaningless responses of any other I know of in A&S forum. Here's the real poop. According to the BB model of the universe, the universe is expanding, but there is no boundary beyond which there is only empty space into which stars and galaxies are expanding into. This is a common misinterpretation due to a widespread inability to grasp the concept of curved space. On a large scale, every can consistently be presumed to be pretty much the same as it is in our neighborhood, although any conclusions about what lies beyond the observable universe are impossible. However, the volume of the universe may be either finite or infinite. This is simply not known. In General Relativity, finite *and* unbounded is not a contradiction.
