What is the full description of the dimensions existing in the Universe?

Well it depends on what you mean by dimensions. Some of the "dimensions" you list are parameters or variables. \n\nHowever, according to the standard definition of dimensions, we know about 4 dimensions (3 space and one time). There have been many attempts to unify the 4 fundamental forces of matter ("unified field theory") that have postulated the existence of more dimensions. This possibly started with the Kaluza-Klein theory, creating a 5th dimension. \n\nModern string theories and other theories require more dimensions. Many different types of string theory exist, and many different suggestions for the number of dimenions exist as well in string theory. However, no one really knows which if any of these theories are correct. The current leading string theory, M-brane theory, requires 11 dimensions.

Universe theories talk about a finite and unlimited Universe. The Universe is unlimited because it has no boundaries. There is no edge, no end where a spaceship would have to stop. See it as a tiny bug walking on the surface of a big balloon. The ballon has a finite dimension, but the bug will never find the end, so it is unlimited from the bug's point of view.\nSo, the Universe can be expanding or contracting or staying the same size. This is a very important question to answer in modern astronomy. Latest studies say that it is expanding, but it has not been totally proved.\nAnd where it is expanding? The Universe is creating more space and time where there is nothing.

The universe is basically everything.  The visible universe is the part of the universe that is known to us, it is the farthest we can see and, hence, the farthest we can study.  There may be more beyond this but it is kind of silly for us to worry much about it at this point because it is beyond our reach.\n\nVacuum (I'm assuming that's what you were typing), is supposed to be the complete lack of matter.  If you say that there is a vacuum inside a box then there should be no atoms inside the box.  We say that space is a vacuum but this is really a generalization.  Space is not completely empty but things thin-out the further you get away from the Earth, our sun, our galaxy...\n\nI'm not sure how one creates a real vacuum.  No one really knows how our universe came into existence but we have a very good guess that it started with the Big Bang.  There is some evidence to support this.\n\nHere are two websites that describe it better than I could if you are interested.\n\nhttp://en.wikipedia.org/wiki/Big_Bang\n\nhttp://liftoff.msfc.nasa.gov/academy/universe/b_bang.html

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.

Our universe consists of four dimensions: three of space and one of time.  This leads many people to think that the "fourth dimension" refers to time, and higher dimensions must be associated with something else.  That isn't true.\n\nTheoretically, there is no limit to the number of possible dimensions, whether spatial or otherwise.  Another universe might have six dimensional space and two dimensional time, for instance.  We can't imagine such a place, but using math, it's pretty easy to describe its properties.

Sorry, as Braxton points out, the size to the edge of the observable universe is 78 billion light years due to the expansion of the universe (same source as the other guy used, Wikipedia) There is much debate as to whether or not the universe is infinite, but many scientists believe that the universe is indeed finite in size.\n\nBY THE WAY: I find it comically amusing how two people can cite the same source, yet somehow I'm the wrong one.  Oh well ;)

Okay I'm sure that there is more than a four dimensions out of this well known reality (real life).\n\nabout that string theory I have read a little from wikipedia and it says something, that maybe, the Universe was caused or founded pherhaps by a big Crunch.\n\nTo simplifies it for myself, I think that every Dimension is a continuing line. String is a very small thing that exist only in that dimension and not just one string but millions of it, but only that type or kind of string, for example a flashlight in a dark room you can see those particles of dust BUT refering the -strings- are actually those specific Lumens or Lux that are producing light and interacting in a very small subatomic scale, and refering -dimension- are that beam coming out from that flashlight all the way long to the wall.\n\nYou see only those lumens are interacting in the beam which is the well known Dimension, (we live in it) The Universe.\n\nBut there is fourth Dimensions apart that Can not even touch the beam of light wich represent the dimension or universe we are talking about, because the other Dimensions acording to this theory are beams (lines) but not of light for example another dimention could be as a water fall that comes out of spout (sink dishwasher). curiously that flow of wather is very similar to the beam of light.\n\nOkay I'm sure that this a very deep thing to think about it but friendly I advice you to not get more further because we are just humans and those are very Interesting themes or topics that we can not reach or complete understud \n\nI always have thought that the universe is spheric very similar like that crystal spheric snow ball present or souvenir they give you on birthdays maybe like a Marble.\n\nBut serious talking againg about Dimensions. you know, The Book talk about it, a dimension of living creatures and you know the other dimension of people that is not here anymore We can Not interact each other. \n\nLUX OR LUMENS (a Small Portion from Wiki)\nAchieving an illuminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12000 lumens. Lighting a larger area with the same number of lux requires a larger number of lumens.

we can measure 4, height, width, length, and time, but there are theories, (super string, and the like) that are suggesting upwards of 11. So, it's a hard question. But the defining part of the answer is, "we live in," and one would then have to answer, just the 4. Peace!

This is a very difficult concept and you probably won't get a great answer for it.  First off, this is only speculation - there is not a shred of evidence that there are 11 physical dimensions.  We can only claim 3 (time is considered the 4th dimension, because you need all 4 to describe to fully describe an event - for example, if you throw a rock in the air, if you want to know everything about where it lands you have to know the longitude, latitude, altitude and time with regards to a reference point).\n\n11 physical dimensions spring from string theory, which postulates that everything including time and space and matter and force are made up of vibrating "strings", either open ended or looped like rubber bands.  These strings are inconceivably tiny - if an electron were the size of the solar system out to Jupiter's orbit, filling in the volume, the string would be about the size of a granny apple.  It's thought that physical dimension 4-11 curled in on themselves at the Big Bang, and are only relevant on the same scales as the strings themselves - the other 3 expanded to fill the universe that we know today.\n\nOne way to image it is to imagine the Earth as a perfect sphere, without mountains or valleys, no hills, no riverbanks, no sidewalks, just a perfect, absolutely perfect sphere.  Now imagine an ant walking on the sphere.  The Earth is so fricken huge compared to the ant that the ant will only think there are two dimensions, x and y (assume that the ant has no self-awareness, and didn't realize he himself is above the x-y plane).  In reality, the Earth is a sphere, with a z component, but the ant will never know that.  The same, in reverse, could be true for the other 7 dimensions - they are so small we can never comprehend them.\n\nUnfortunately, with today's physics, that also means we can never confirm or deny their existence.  Without empirical proof, string theory is just beautiful mathematics, without a shred of proof.

According to string theory, the strings are the universe's \nelemental material. They vibrate in different ways and can\njoin and break apart to form different elemental particles\nthat make up the universe. The strings exist in 11\ndimensions: time, which physicists consider a dimension, and\n10 spatial dimensions. Four of those dimensions are the ones\nwe are familiar with, three spatial dimensions plus time.\nThe other dimensions may be so small they're invisible to\ncurrent detection equipment and are only known to exist because they leave a "footprint" of where they have been.

Ok...we don't know how big the entire universe is. It may well be infinite, which, assuming it is homogeneous, would mean that it has infinite mass. At any rate, physicists currently think it is "much larger" than the observable universe. How much larger? I don't think that they have any evidence. But let's assume that we can see 1% of all visible space. This would make the mass of the universe = 100 * 3 * 10^52 kg, or 3 * 10^55 kg.

sorry i must really correct the first answer before i continue;living in a 10 dimensional world is just a theory,known as string theory,and that is all it is,there is no proof\n\n(and the theory ACTULLY states that there are 11 dimensions)\n\na 2d object could not even physically exist because even if you had the smallest possible object that could exist indepdantly(an atom) it still has dimensions of length width and height,however small it may be it is not 2d\n\nIn writing the answer im kinda curious as to Could you theoretically stack and infinate number of 2d objects on top of each other and it still remain 2d?? anyone know?

1 dimensions is a line    width, but no height or depth\n\nif you lived in one dimension you might know the person or thing on each side of you, but you could never pass them, there is no way to go around or over them because there is just the one dimension, back and fourth\n\n2 dimensions is a plane    width and depth but no height\n\neverything in a two dimensional world is flat, you could go over or under something you met but not around because there is no around, you are flat and so is everything else\n\n3 dimensions   is like our spatial universe width, depth and height\n\nthings have volume\n\nsome constructs use time as a 4th dimesion but that is really a different deal, there are only 3 spatial dimensions that we can percieve.  it is hard to imagine what another spatial dimension might be like

Well there are 3 spatial dimensions and one temporal dimension, so there's 4 to begin with. On a macroscopic scale the universe behaves like a minkowski space. However on a microscopic scale even 4 dimensions isn't enough, the maths suggests possibly 11 or more dimensions.\n\nHowever I have a feeling you're not talking in the strictly mathematical sense. If you meant "are there other universes 'beyond' ours", then I have no idea. There are theories that suggest there are, but as far as I know there are no known observations that could answer that yet. We'll just have to wait and see what is discovered.

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).

The smallest anything can be is called Plank length and it is approximately 1.6 × 10 (to the -35th power) meters.  \nAssuming "we" is the earth, we are very small compared to the size of the universe.  The "volume" of the observable universe is about  1.9 × 10 (to the 33rd power) light years, and the earth has a volume of approximately 8.2 x 10 (to the 12th power) miles, or 4 x 10 (to the -26 power) of a light year.  The universe, then, is about 4.7 x 10 (to the 58th power) times bigger than the earth.

We observe four dimensions everyday, three spatial and time.\n\nBut...theories such as string theory predict that the space we live in has in fact many more dimensions (frequently 10, 11 or 26), but that the universe measured along these additional dimensions is subatomic in size. As a result, we perceive only the three spatial dimensions that have macroscopic size.\n\nThis is not so strange as it sounds, which I'll show with an example. Imagine you are in an airplane, flying over sea. Seen from a height, the sea looks flat, two-dimensional. But when the plane looses height we start to perceive the waves, that move in a third direction we could see before.\n\nThe universe could be the same. Four macroscopic dimensions and a few more, hidden ones. We can only perceive them for instance, by the small effects their existence might have on subatomic particles.
