Do you believe in dimensions?

i think there are parrallel dimensions that acctually collieded to create this universe, i saw it on the discovery channel.  Then again Dan brown's "Angels and Demons" sets off the idea that there is another parrelel demension exactly the same as our except everything is created of anti matter, the alternate of matter, therefore once antimatter and matter collide, boom both disapate.  They have been able to create anti matter.  (can you mark this as best answer)

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?

Time And Relative Dimension (or Dimensions) In Space

We observe four dimensions everyday, three spatial and time.\nTime is called a dimension because it makes mathematical sense to do so. \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.

this is sort of trival, dimensions can be thought of as derivatives, and you can take a formula and make any number of derivatives of the original derivatives and still end up with a line that bends, indicating no limit to the number of dimensions we can really conceive..   \nModern string theory is a bunch of hoo haa,   such a sub-atomic idea makes no sense, the reality we know could not have order if there were "strings".  "strings" have no way of organizing themselves into different sub-atomic particles, the universe would just be a bunch of "strings"

The problem with detecting the fifth dimension (or the sixth, seventh, and so on, it is believed there are 11) is that our bodies are built to measure only the three old-fashioned spatial dimensions, plus time as a fourth dimension.\n\nScientists have been hoping that at least one of the extra dimensions might be rolled up in such a way that its influence could be seen by measuring gravity's pull on a scale of, say, a millimeter or less. So far, no anomalies have been officially reported, although there have been occasional blips that are likely due to tiny experimental errors rather than the fifth dimension.

Alot of people pinned down 4 dimensions pretty good, but nobody has explained the dimensions beyond 4 very well, except to say that they exist. Let me take a shot:\n\nOPE did the best job of explaining the first 4 dimensions, I'll summarize and then move into the other ones.\n\n0D: Imagine a point, the smallest little dot with no length. There is only one point in this dimension, 0.\n1D: Imagine a line that can have any length in 1 direction but no length in any other direction. We can describe a point on this line with one coordinate, x.\n2D: Imagine a sheet of paper that is infinitely thin (you hold it sideways you see nothing). We can locate a point on this plane by (x,y).\n3D: This one's easy. You find a point in 3D space by (x,y,z)\n4D: Harder. In 3D, your point cannot change. You cannot move around because in order to change position you need one more dimension, time. For a point to move from one place to another (dx,dy,dz) it requires a change in time (dt). To locate this point now you need to define its position as (x,y,z,t) or else you won't find it. If you imagine your point is a person you want to meet, you would have to be told where in space (x,y,z) they will be and when (t) they will be there, or else you are not guaranteed to find them (unless you both have cell phones).\n5D: The hardest. Go back to 0D (a single point). If we were able to shrink down to the size of this point, instead of seeing a point, we would see a tiny circle. So if you were trying to locate a point in 5D, you could not locate it exactly unless you placed it in (x,y,z,t) and w, it's location on that circle. So you now have (w,x,y,z,t). The radius of this 5th dimension is so small that we can't see it, but we should be able to perceive its effects when our technology improves. It makes a lot of sense mathematically because it explains why we can't explain gravity at tiny (quantum) levels. The math doesn't work unless we add dimensions and wrap strings around them. Note that dimensions 5 and up have a property called compactification. That means that anything operating on the compactified radii of these dimensions moves in a complete circle, always returning to its original position. The radii are so small that we cannot percieve a change in position at all; a particle changing position along one of these dimensions seems to not move to us.\n6D and up: Very hard to imagine. Your point can now be found on two circles. The easier way to think of this is a point on the surface of a sphere, which will give it two coordinates on a tiny round surface (like longitude and latitude on the Earth's surface). Now you can add as many compactified dimensions as mathematics permits given whatever theories you are trying to incorporate. Your compactified radii can be given upper and lower limits to allow them to be plausible.\n\nI saw some people say infinite dimensions and another say 27. The reigning theory has 11 dimensions. 27 dimensions comes from a part of string theory that claims that matter does not exist and that there exists a fantasy particle with very strange properties, called a tachyon. This theory ties in to the most prominent theory, M-theory, which says only 11 dimensions is needed to explain everything.

It all dependend where you are filling time. In an insane intitution there are people who experience 4 ,5 of more dimentions . so far I have heard of 26 dimensions being filled including many dimentions of time.\nSpace and time have the same thing in common they can be filled both at the same instance!

at the present time we define the universe by four dimensions, length, width, height, and time.\n\nhttp://en.wikipedia.org/wiki/Spacetime

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.

space might have more than three dimensions; we don't know.  edwin abbott wrote a very famous book called "flatland" about people who were confined to life in a two-dimemsional world, and what it was like to live there.  it was part geometry, part philosophy about the nature of the universe, and part statement about the social behavior of humans.  it's excellent and you can read the whole thing online at the link below.

I am not sure about life more than 4 dimensions. Why? Is this funny for you?

it is the theoretical dimension often refered to as Hyperspace and of Subspace.\n\nbasically if you fold the universal plane til the oopsite sides touch. and then drill a hole (wormhole)\nthrough to the other side the space inbetween is theoretically the 5th dimension.\n\nalso theorized is similar but that the 5th dimension is at the bottom of a black hole.  or on the other side.  \n\nONLY GOD THE CREATOR OF ALL THINGS knows for sure.

Mathematically n dimensions can be described but our experience is only 3 dimensions So the properties of fourth dimensonal shapes can be mathematically described and a fourth dimensional quantity that is in units^4 can also be calculated\n\nThis is an argument that the 4th dimension is time. That cannot be the case when one considers the properties in 3d are L, L, and L One would immediately envisage that the 4th, 5th .... nth dimensions would also all be L\n\nA tesseract, the 4 dimensional equivalent to the 2 dimensional square and 3 dimensional cube, is not a time related object at all. Its 3D projection can be build and the objects equivalent of a 2D shadow seen easily. In 4-space it occupies L^4 units^4. Wikepedia has some interesting information and projections of a tesseract

There seems to be a lot of confusion on this site as to what a dimension is.  A dimension is not an alternate reality or a parallel universe, or anything like that. A dimension is simply a direction. For instance, the first four dimensions are Length, Heighth, Depth, and Time. Diminsions(directions) beyond these four have been mathmatically postulated, but we cannot perceive them with our senses. We can only percieve time in one direction(Past), so while we "see" only three & 1/2 dimensions, there could, and probably are, others. But they are just other directions, not other worlds. So, if you sent a camera into a black hole, could you see other dimensions-no.  First, nothing we are capable of building could withstand the tidal forces of a black hole's gravitation-it would be destroyed in nano-seconds.  Secondly, no energy can escape a black hole, so we would be unable to receive any signal back-and that includes energy through a cable, folks. Lastly, even if those two obstacles could be overcome(not likely), the effects of relativistic time dialation would be so extreme that we wouldn't get a signal back until the universe ended, at which point the data would be meaningless. So we can realistically count on seeing nothing through a black hole. Be neat if we could though-who knows what we might discover?

I fear i had even thought about the ∞ dimension once. Nearly anything could be described as rotations there. It has took a long time to get a foot on earth again.\n\nTime is not the real 4th dimension. Perhaps c*t. Look at this 'Minkowski space' thingy:\n\nhttp://en.wikipedia.org/wiki/Minkowski_space\n\nIf you measure across space AND time, there are negative distances. What shoud a negative distance mean in reality?\nIf you consider time as the 4th dimension, it is just a convenient way to write down long terms shortly or to visualize complex relations concisely. It isn't more than just mathematics.\n\n\n"As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality." \n\nAlbert Einstein (personally himself)
