What dimension do we think in?

Our thought are information and dependent on the physical reality of brain. You can not project your thoughts beyond the confines of your brain, unless they are piggy-backed on a transfer wave, such as the intelligence of radio waves is piggy-backed on carrier waves; all physical. You are confused, because instead of getting a proper education in these matters, you wish to believe some form of " alternative " explanation to reality.

space as we see it has the three dimensions of space and one of it .But if u want to explain everything that is happening around us we have to assume that space is multi-dimensional.I know it is quite hard to imagine and think about a space having dimensions greater than 3 (also caled hyperspace)but there is no way out.A mathematics devised by reinmann is used to study hyperspace .It is easier to write down the equations of hyperspace than to imagine it.Gravity is also defined as the bending of this hyperspace.Many scientist's also believe that hyperspace can give us the answer for an unified field theory.

Classical physics theories describe three physical dimensions: from a particular point in space, the basic directions in which we can move are up/down, left/right, and forward/backward. Movement in any other direction can be expressed in terms of just these three.\n\nTime is often referred to as the "fourth dimension". It is, in essence, one way to measure physical change. It is perceived differently from the three spatial dimensions in that there is only one of it, and that movement seems to occur at a fixed rate and in one direction. The equations used by physics to model reality often do not treat time in the same way that humans perceive it.\n\nTheories 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.

If there are higher dimensions, we're definitely in them, but we're still confined to our 3 dimensions (lenght, width, and height), note that you cannot control time.

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.\n\nSerious enough?\nThe reference is a general article on the mathematical notion of dimensions, that contains links.

Actually, the first two answers are right; but, disregarding time, if we were 4-dimensional beings we would still only cast 2-dimensional shadows.\n\nEven 2-dimensional objects also only cast 2-dimensional shadows.  Anyway, what would your 4th dimension be?\n\nShadows are merely the result of an object being between the shadow and the light source; shadow is merely absence of light.  Shadows are always 2-dimensional.\n\nAnd as far as considering time to be a dimension goes, we are IN the dimension of time, but we are not IN the dimensions of width-height-length.  They are attributes used to describe us; they are part of us, we are not part of them.

There are heavenly many dimensions.\n\nYours sincerely,\nThe Immortal God.

The 4th dimension is time. It is essentially equivalent to "flat land" falling through the 3rd dimension.

Dimensions are not the same thing as a parellel universe.  It's one popular misconceptions carried on by mystics but created by turn-of-the-20th-century scientists when spirits were thought to exist in higher dimensions.\n\nDimensions are concepts of sides of objects and time, no more, no less.  We exist in what is visually a four dimensional universe, height, width, depth, and time.  We can't visualize objects in higher dimensional space because there is no evolutionary advantage to such a thing; tigers don't leap out at you from the fifth dimension.  String theory suggests there are 11 dimensions (or more); at the Big Bang all the dimensions existed at once then split apart.  Our 4-dimensional universe expanded in the however many other dimensions (the number depends on the theory) shrunk down to the Planck length (10^-35 meters).\n\nA parallel universe is usually what people and mystics mean when they say dimensions.  Even though a parallel universe is technically just another universe existing just out of reach of our own (possible even nanometers away).  This theory seems to be common to multiverse theory, string theory, m-theory, and a few others.\n\nOnward, if we shrink to smaller than an atom, down to the Planck length for example, we'd not lose our four-dimensionalism.  We'd just be really, really small.  We wouldn't be visible to the naked eye nor the most powerful of electron microscopes.  Nothing that exists today can probe down to that desperately small scale; there are plans to eventually do so, however.  We wouldn't slip into another world or into a 3-dimensional space (length, width, and time).\n\nThis isn't an insane question, nor is it stupid.  It's actually asking something very simple.  Remember Einstein asked himself a simple question when considering light.  "What would happen if you were to race alongside a beam of light?"  Einstein was a master of looking at things at their simplest level; from that question above came one of the most remarkable and elegant theories ever to exist: Relativity.

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.

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.

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?

Imagine you put a yardstick on the floor facing exactly north and south. That would be the first dimension. Moreover, north and south anywhere in the room would also be the  first dimension. Now, put a second yardstick down on top of the first but facing east and west so they look like a big plus sign. That would be the second dimension. Notice, and this is very important, the two yardsticks are at right angles to each other - 90 degrees. All dimensions must be at right angles to each other. Now, put a third yardstick with the other two but remember, it must be at right angles to BOTH of them. There is only one way it can be oriented - in the center of the plus sign standing straight up and down. This is the third dimension. Take time either to try it or to actually build what I have just described using rulers or pencils and satisfy yourself that all three dimensions are actually 90 degrees to each other. Now go one step further. Can you add another yardstick (or pencil) which is at right angles to ALL THREE of the others? Before you exprience brain burnout I'll answer that for you. No - although you might like to try. You can't do it because we live in three dimensional space. However, many scientists feel that there is a fourth dimension although it can't be drawn or built - just imagined. Remember, it would have to be at right angles to each of the three spatial dimensions. Many scientists think the fourth dimension is time. No matter how we turn or in what direction we face, time is always like a yardstick facing behind us into the past and forward into the future. Remember, this is just a theory, an idea supported by many facts and observations but one which has not yet been proven. Are there more than four dimensions? Possibly. In math we can have as many dimensions as we want but math is strictly a mental exercise. The fact that math so nearly predicts what the actual universe is like is a tribute to the perfection of the universe.

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.

Basically, the space that you and I experiences daily is 3 dimensions: up/down, left/right, forward/backwards. But space doesn't have to be 3 dimensions. It can be any number of dimensions. Of course, it is very difficult for us 3-dimensional beings to imagine what these dimensions are, or where they are. The problems is that we can NEVER see the fourth spatial dimension, never mind the 5th or the 6th, etc. etc. Let me explain why.\n\nImagine for a moment that we are 2-d beings, not 3-d. And we live on the surface of a sphere (like a ballon). This sphere is our universe. Everything we see, touch and experience happens on the surface of this sphere. We can go left/right and forward/backwards. But we can never go up or down. When we travel in one direction, we will eventually circumnavigate the sphere and make a complete circle, which brings us back to the initial starting point. If we ask the 2-d beings to imagine 3-dimensional space, all we can tell them is that the 3rd dimension (up/down) is orthogonal (a fancy way of saying perpendicular) to the surface of the sphere.\n\nThis is exactly our situation when we talk about the 4th, 5th, 6th, whatever nth dimension. They are defined as the dimension that is orthogonal to the n-1 th space. So the 4th dimension is orthogonal to our 3-dimensional space, and the 5th dimension is orthogonal to the 4-dimensional space, etc. etc.\n\nNow about Super String Theory and these higher dimensions: what the theory predicts is that our universe does indeed have more than 3 spatial dimensions. Some version sof the theory say there are 10, some say there are 11. Whatever the number (it doesn't really matter in our discussion here), these higher spatial dimensions are currently curled up into very very tiny spaces. So what does that mean?\n\nWe now go back to our 2-d being living on a sphere example. For the time being, let's say we are now on a flat 2-dimensional surface (like a sheet of paper). Super String Theory says that the higher dimensions are curled up. So let's consider in our case the 3rd dimension as the curled up dimension. This means that if we were to magnify any point on the 2-d surface all the way to about 10^-35 meters (Planck Length), we will see that there is a tiny loop (like a loose thread on a knitted sweater).\n\nNow imagine if our 2-d being were (1) small enough to see and fit inside the loop, and (2) able now to travel in the 3rd dimension, then for it to go in the up/down direction, the 2-d being will now be just going around in circles inside the loop. Remember in the previous case, our 2-d being can travel in one direction on the surface of the sphere and then return to the same point. Well, here our 2-d being is traversing through the 3rd dimension, except that there is no up and down because the 3rd dimension is "curled up" into a loop. So the 2-d being just goes around the loop in circles.\n\nIf you understood the above, then now we can answer the question, what and where are these higher dimensions in our universe. They are culred up in every point in our 3-dimensional space, and if we were small enough and we could move into these higher dimensions, then we would be moving through these very convoluted curled up loops, but not really able to go anywhere.\n\nBecause these higher dimensions are curled up into such tiny tiny loops (remember 10^-35 meters), only the most elementary structures like "strings" are affected by them. The size of these strings are of course on the order of 10^-35 meters long, and can traverse through the curl up dimensions. When the strings vibrate, the vibrations in the 3 large dimensions don't have any effect, but in the curled up higher dimensions, the vibrations can create resonance like playing a musical note.\n\nThese resonances are the stuff of reality, meaning these vibrational resonances of the strings inside the curled up dimensions is what creates matter and energy and thus everything that&#

Certainly. Would be a total waste not to use all the possibilities. How much of the dimensions you see is I guess dependent on your awareness level, which in time probably increases. Now this goes into spiritualism, which is mainly speculation, but I think after you die, if you have gathered enough experience, you raise in awareness level, and the next time you are born in a body, it will be one, that is capable of "seeing" more dimensions.

I might be able to answer more fully if you reword your question and put some thought into exactly what it is you're looking for.  For example, string theory predicts extra dimensions beyond the four we experience.  Is that it?  Or are you referring to the Branes explanation, where there are extra dimensions as well as additional universes removed from our own?  Get some additional details and I'll edit.
