If the Universe in infinite?
963962
I've started to wonder if it's possible it's rotating around a center point possibly, maybe from our point of view we assume it's expanding.

the question is, what is there to block the universe from expanding?  The theory of going out one end and coming out on the other would break any and all laws of physics and space that we hold today, which, is a possibility, but not a likely one.  Also, the concept of infinity doesnt need to follow regular laws of mathematics, because infinity is not a number as some poeple have been treating it here.  Infinity is a concept, where infinity means increasing by an infinite amount, as in, ongoing and never ending...it is a concept, not a number.  So, how can the universe go on forever? it may not be able to, but with our current laws of physics, unless there is soemthing with an equal or greater power to stop the space matter and such that is expanding in light years, then the universe will never stop expanding.  Before the "big bang THEORY", (again, theory, not law as someone was using it to make their point) thee must have been some type of area occupying what our current universe is eating up, since again, by our current laws, you cannot make something out of nothing, so, my thought would be that the universe will expand as far as the previous area which it is expanding into, because it cannot expand to make something our of nothing at all, or so our current laws say...

You get into Quantum Theory with your intrigue and there is no evidence to support that the universe is not infinate.\n\nHOWEVER, according to the Big Bang theory there was nothing and then there was something in a centralized location millions (billions) of years ago. At the speed that the universe is spreading outwards there has to be an end to it and scientists are trying to get telescopes powerful enough to see to the beginning of time.\n\nWhat lays on the other side? Nobody knows.

There is disagreement over whether the universe is indeed finite or infinite in spatial extent and volume.\n\nHowever, the observable universe, consisting of all locations that could have affected us since the Big Bang given the finite speed of light, is certainly finite. The edge of the cosmic light horizon is 13.7 billion light years (4.19 Gpc) distant. The present distance (comoving distance) to the edge of the observable universe is larger, due to the ever increasing rate at which the universe has been expanding; it is estimated to be about 78 billion light years (7.8 × 1010 light years, or 7.4 × 1026 m). This would make the comoving volume, of the known universe, equal to 1.9 × 1033 cubic light years (assuming this region is perfectly spherical). The observable universe contains about 7 × 1022 stars, organized in about 100 billion galaxies, which themselves form clusters and superclusters. The number of galaxies may be even larger, based on the Hubble Deep Field observed with the Hubble Space Telescope. The Hubble Space Telescope discovered galaxies such as Abell 1835 IR1916, which are over 13 billion light years from Earth.\n\nBoth popular and professional research articles in cosmology often use the term "universe" when they really mean "observable universe". This is because unobservable physical phenomena are scientifically irrelevant; that is, they cannot affect any events that we can perceive. See also Causality (physics).

There is no end, it is infinite.

First off you have a real good question.  As a matter of fact I used to think like this during my high school years.  \n\nInfinity in cosmology\nAn intriguing question is whether actual infinity exists in our physical universe: Are there infinitely many stars? Does the universe have infinite volume? Does space "go on forever"? This is an important open question of cosmology. Note that the question of being infinite is logically separate from the question of having boundaries. The two-dimensional surface of the Earth, for example, is finite, yet has no edge. By walking/sailing/driving straight long enough, you'll return to the exact spot you started from. The universe, at least in principle, might have a similar topology; if you fly your space ship straight ahead long enough, perhaps you would eventually revisit your starting point.\n\nIf the universe is indeed ever expanding as science suggests then you could never get back to your starting point even on an infinite time scale.

By "is outer space infinite?" I assume you mean "is the universe infinite?" The answer to this question is NO. The universe and outer space is NOT infinite.\n\nOur current understanding on the origin of the universe tells us that the universe was created in a Big Bang, and that the universe has been expanding ever since (for about 15 billion years). Since light travels 186,000 miles per second, a light-year is about 6 trillion miles or 6 x 10^12.  So 15 billion light years is about 9 x 10^22 miles. This makes the universe very large indeed, but still NOT inifinite.\n\nBTW, this is just the size of our universe. There maybe other universes as other people have indicated, but there is no point talking about them, because we don't know for sure they exist but we are VERY sure that our universe exists.

The universe is infinite and is expanding; there is no middle.

In the infinite universe it is very very likely that the number of Gods is infinite, too. Each God must have a God superior than herself. That is all to it. Either the Gods are limitless or there is no God at all. This is logic . The rest is nothing more than rubbish thinking or "feeling" as they might call it.....

This "nothing" is what we perceive without the laws of physics. Our universe is limited by the knowledge we have about it. Recent theories (the "M" theory) suggest that endless universes exist, and sometimes they even collide one into other. Probably, out there, beyond the boundaries of 12 billions light years, others dimensions, other plan of existence exist.

Once you leave the Milky Way you are not outside the universe. The Milky Way Galaxy is one of many known galaxies in the universe. There are probably billions we don't know about. "Goodness knows where" is inter-galactic space.\n\nInfinity means "forever". It is not necessarily a measurable distance or time. We're not sure if the whole universe is infinite. We can't even see most of what is out there. The estimated size of the observable universe is 7.4x10^26m (that's really, really, really, really big). Beyond that we're not sure yet.

Evolution is infinite.

does the universe end?  no one knows yet.  the beginning of the universe is much better understood.\n\nhttp://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

Imagine a situation where you would come back to your starting place no matter which direction you go as long as you kept going far enough. This is true, for example, on the surface of a sphere. But it turns out that there are analogs of this for going any direction in three dimensions. In this case, the universe would be finite (like the surface of a sphere), but would have no boundary (again like the surface itself). This is actually a simplified version of the models used by physicists for describing a finite universe. In reality, the evidence suggests that the universe is infinite.

Universe in not infinite. It is finite and constantly expanding. Yes there are more galaxies than no. of grains of sands in all beaches of the world. This universe is unimaginably huge!

There is disagreement over whether the universe is indeed finite or infinite in spatial extent and volume. Many astronomers and cosmologists believe the universe is infinite due to recent findings in NASA's WMAP project supporting a flat (therefore infinite) universe\n\nHowever, the observable universe, consisting of all locations that could have affected us since the Big Bang given the finite speed of light, is certainly finite. The edge of the cosmic light horizon is 13.7 billion light years (4.19 Gpc) distant.

yes, there are infinte, the universe is infinite and besides that, there are infinite spacial-temporal or just temporal realities, not just one, not ten, not a million but infinite. Just imagine ! You should read The Fabric of Reality by David Deutsch. a great scientist in physics and , he is English, proffesor at Oxford I think.
