What is the full description of the dimensions existing in the Universe?
108313
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.

This is actually really interesting thesis. If we somehow managed to prove the fractal structure of the universe i guess we would resolve so many physical and astronomical questions...\n\nBut the mathematic functions for the fractals create structures on the two dimensional field which have an infinite property, therefore their dimension is somewhere between 2 and 3. \n\nBut if you're talking about space and atoms, you need to add the dimension of depth (third), dimension of time (4th) and probably some more dimensions that haven't even been discovered yet. \n\nBesides that, fractals are static and the universe is always shifting and changing and expanding. \n\nTherefore I think that with the knowledge and sources and technology we posses nowadays, it is impossible for us to figure out the fractal equation that determines the atoms in the same way as the galaxies.

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.

I believe that the universe is expanding within higher dimensional space. As humans we can only understand this universe in three dimensions because that is all our primitive tools of perception will allow. We are "trapped" in three dimensions. However, the existence of higher dimensions has been proven mathematically time and time again. I'm no expert on the subject but I have done a little reading. I would reccomend reading something by Stephen Hawking such as "Stephen Hawking's Universe" or "A Brief History of Time." Also, "Hyperspace" by Michio Kaku gets a little more in depth with higher dimensional theories. The only way we can understand an expanding universe is through expanding our minds along with it.

You might as well have asked what are the dimensions of the universe.\n\nYou need to narrow down to state, prison or jail etc.  Every state does prison time differently and every county does jail time slightly different as well.

According to classical physics 3: length, wideth and depth.\nModern physics add to that a fourth dimension - time.\nThose we now for certain exist. But there could be more (as much as 10 or 11 according to superstring theory).

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.

Isn't the universe infinite? How can it have a definite radius or circumference if it's infinite?

As far as you’re concerned there are three. That's what you are able to sense, measure and perceive; height, width and depth. Einstein theorized that time was a forth dimension but since you can’t change your position relative to time like you can height, width or depth, it’s doesn’t exactly work the same way. \n\nThe space you exist in has but three dimensions. Perhaps there are more dimensions but since you can’t experience them, they don’t have direct effect on you, if any effect at all, if in fact they even exist. \n\nSome Metaphysical theories postulate infinite dimensions but since no one has visited those other dimensions, they remain in realm of theory only.

the universe is expanding into "nothing", is that so hard to understand? yes it is. according to the latest version of string theory, our universee is just one little speck in a whole giant "Landscape of probabilities", with as many probabilities as 10 to the power of 500, and more then 500 dimensions, so can you imagine living in a world with 500 dimensions? no! its impossible to imagine. \ntry to imagine our univers being a giant balloon constantly expanding, outside of this balloon there is nothing, void, by expanding, our universe is creating Space-time as it expands. i know some of those concepts are simply impossible to visualize, but mathematically it make perfect sense.

There are in fact quite a lot of secrets of the world, I'll list a few:\n1. The world might be stranger than anyone could imagine.\n2. There could be 11 dimension in the world, 3 dimensions of lenght, width, and height, one dimension of time, and 7 curled up dimensions to small to be seen.\n\nImagine if you're holding a long stick real far, it would look like a 1 dimensional object, but if you get closer, you notice that it has 3 dimensions.  That's what they think about the 7 curled up dimensions, they're billions of billions of times smaller than an atom!\n\n3. There are at least 7*10^22 stars in the universe, that's 7 with 22 stars.\n\n4. There might be several parallel universes, some other universes could be 1mm beside you!\n\n5. Scientists now think that gravity may not be so weak after all, but a lot of gravity escapes into higher dimensions. \n\nThis intrigues an amazing possibility.  Since humans cannot see, hear, feel, smell, or taste the other universes, they think that they can communicate with other worlds using gravity.  For example, gravity phones might be developed in the future.\n\n6. Everything in the universes(all matter, forces, etc.) might be made up of tiny strands of vabrating energy called strings.  Strings are nearly 10^-34m small, that's 0.0000000000000000000000000000000001 metres small!\n\nThere are lots of other secrets, but these come to my mind first.

Scientist belive there are several dimesions.  Remember dimensions are based on measurement.  Length width height, 3 dimesions so we are in the third dimension.  A showdow for example only has length and width so it is the 2nd dimseion.  We cannot comprehend other demensions because we live in a 3d world where only LWH exist.  It is like asking your shadow what is tall, he would know because he lives in the 2nd demsiond.  So there are other dimensions yes and we can dicipher them though the wonders of mathmatics and physics.\n\nGravity works likes a bowling ball on a bed.  Think of the bed as the fabric of space.  If you put a tennis ball on the bed it would "gravitate" towards the bowling ball.  This is the theory of realtivity.  A worm hole forms when a really heavy mass punches through that space fabric.  If you had a million pound bowling ball it would go right though the bed.  The same things happens in space that heavy mass punches right though to the other side forming a worm hole.

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.

"...What are the dimensions (length, width, and height or thickness) of the physical universe (in light years)?..."\nThe universe can't be measured in terms of length, width, and height. Such parameters require some reference point from which measurements can be made, along with some distant boundary where the measurement would end. You simply can't do that with the universe because the universe is isotropic, meaning it's the same in all directions from any observing point. From Earth we can look outward in any direction and 'see' about 13.7-billion light years. From Earth that represents a boundary. Here comes the tricky part: if some alien in a galaxy 13.7-billion light years away from Earth looked outward in all directions (including back towards Earth) they'd 'see' a universe that appeared to be 13.7-billion light years in scope. In other words, the universe has no boundary. To have one it would have to be inside some "thing" else, and there's absolutely no evidence that such is the case.\n\nTo confuse the issue even more, if we had the ultimate telescope with limitless viewing power we still will never be able to see into the universe beyond a certain range. That's because at almost the same instant of the Big Bang the universe briefly expanded faster than light (this doesn't violate relativity because it was the space of the universe that did the expanding). In our 'normal' universe the speed of light is the speed limit which prevents us from ever seeing any of that inflation because it's moving away faster than the speed of light.\n-----------------------------------------------------------\n"...I've read that the universe is thought to be "saddle shaped..."\nMore recent observations point more towards the universe being geometrically "flat." This simply means that the universe appears to be infinite, that its space will expand forever while cooling more and more over the eons.\n------------------------------------------------------------\n"...What does it mean for example, to say that the universe is expanding at a rate of 70 kilometers per second per (x number of light years)?..."\nYou've described the so-called Hubble Constant. (70 km/sec/Mpc) It means if galaxy 'A' is 1 Mpc (1-million ly) away from us it's recessional velocity will be 70 km/sec. If galaxy 'B' is 2 Mpc away then it's velocity will be 140 km/sec It's important to keep in mind though that it's space that's expanding like that, not the galaxies moving THROUGH space; they just get carried along.\n------------------------------------------------------------\n"...I was not able to find a rate of acceleration of expansion..."\nI've been looking for a figure too. So far the only thing I've come up with is -3.15^36 /sec/sec  Darned if I know what the units of measurement are though. Maybe someone else on Yahoo can help us out with that.

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
