Does any one think that there are parts of us poking out in the 4th,5th etc. dimensions?

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!

The three dimensions they are most likely talking about are the x,y, and z planes in space. Time is the fourth dimension, and there could be more after that. read stephen hawkings book A Brief History of Time. He explains how to conceptualize dimensions in your head very well.

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.

I find it to be quite fascinating.  Although mind-bending as well (11 dimensions - my brain hurts just thinking about it).  I don't know if it is correct or not (well, no one knows for sure), but it seems to have potential, particularly with resolving the Relativity/Quantum Physics battle.

Refering to the four dimensions, I assume you mean three spatial dimensions, and one of time.  This is correct.\n\nString Theory, which is a possible candidate for the Ultimate Theory of the Universe, demands that there actually be ten spatical dimensions!  Four spatial dimensions is impossible for our brains to comprehend and picture let alone ten.  \n\nYou might be wondering why we aren't aware of the extra seven dimensions if they do exist.  The reason: they are curled.  Let me explain what that means.\n\nImagine looking at a clothesline.  From afar, it looks like the clothesline only has two dimenions: you can either go left or right.  Now when you move closer, you are able to see the third dimension of the line, which would allow say an ant to crawl around (up and down) as well as left and right.  You couldn't see that dimension from afar because it is curled up and very small.\n\nThis is the same principle with the other seven dimensions.  They are curled up, and can only be seen if we were able to probe to a small enough distance.  This distance is actually a millionth of a billionth of a billionth of a billionth of a centimeter!  That is way too small for us to be able to see today, and probably for quite some time.\n\nThere are some tricks though for getting a feel for 4 dimensions.  You consider an example that relates 2-D to 3-D, and then apply that to relating 3-D to 4-D.\n\nFor example: imagine a table top is a 2-D Universe, and on that Universe lives a being shaped like a square.  If you were above this 2-D plane and were to talk to the square, he would hear you, but not see you.  If you decided to show him a sphere, would have to pass the sphere through his 2-D Universe.  The only problem is, he wouldn't see the 3-D sphere.  He would see at first a point, followed by a succession of circles that kept growing until you reached the mid-point of the sphere, which would be the biggest circle.  Then as you continued to move the sphere through the plane, he would see a succession of circles that got smaller until he saw a point, and then nothing.  The point is, he would only see cross sections of the sphere, which are circles.  \n\nNow apply that to our Universe.  If a being were in the fourth dimension and tried to pass a hypersphere (a 4-D sphere) through our Universe, we would only be able to see cross sections of that hypersphere.  What would we see?  We would see a succession of 3-D spheres that kept growing, reached the largest size, and then shrunk back down to nothing!  So, the cross section of a 4-D sphere is a 3-D sphere.\n\nHere is another really cool example.  Going back to the square being, let's say he had a safe.  His safe would have four walls, in which one of the walls would act as a door.  It would basically be a hollow square.  Since there are four walls, a 2-D being in that Universe would have no chance at getting any money out of the safe without opening the door.  However, you being in the third dimension above the 2-D plane, could simply reach in and grab the money coming from the top. It would be a complete magic trick to the square.\n\nSimilarily, a 4-D being could reach in our 3-D safe reaching in from the fourth dimension, and take our money without opening the door!\n\nHope that helps.

Yes I do. Think of how big we can honestly say we know that space is, then think a million times that size. There are probably millions of different universes out there.

Thank you! Very informative (and correct) information!\nWell, according to Physics, the same vast quantities, dimensions etc., we have to the large scale, we also have to the small scale, going from our size into smaller (cells, moles, atoms, electrons, nuclei, ....)\nFurther, according to my theory, the Universe we described above is the connection between other universes! As a matter of fact, each one of us is a Universe greater that the one we usually talk about! After all, people discover the dimensions, Greeks named 4 of them and we, somehow think we understand them! People understand only what has been named! That is why we can not comprehend the other dimensions, since we have not discover how the Greeks named them!

Look at your watch.  That is the 4th dimension.  TIME>

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&#

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.

The fact that we can observe only four dimensions seems obvious, but that doesn't mean that there are not more.\n\nAs an example: the sea as seen from an airplane looks pretty flat and seems to have two dimensions only. But as the airplane looses height, the waves can be distinguished and we see that the see surface in reality is three-dimensional.\n\nThe same might be true for the universe: it could be that more dimensions are present, but we don't see them as they are tiny, too small to observe from our human scale.\n\nTheories that suppose the existences of more dimensions have been proposed.\n \nThey were invented because we are not so happy about the models we use now. For instance, there are four forces in nature. Three of them -electromagnetism, the strong nuclear force and the weak nuclear force- have been combined into one force that has three manifestations at our energy scale.\n \nTo model the fourth force -gravity- Einstein invented general relativity.\n\nThe problem is that both theories are incompatible. Calculations done with them in the region where they overlap, notably when we go back in time to the Big Bang, give different results.\n\nThat is ...embarrassing.\n\nSome of the newer theories, like superstring and M-theory, try to overcome these problems. The price to pay is the assumption of extra dimensions.

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.

In our three dimensional universe, time is considered the fourth dimension.

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.

Our universe has 4 dimensions of space-time, and the domain of these domains is finite.  However, the expansion of that is in a larger dimensional space--meaning more than our four dimensions, with higher dimensions orthogonal to our four.\n\nThink of the 2-D surface of a balloon.  If you were a 2-D being on the surface on that balloon, you'd have no concept of the 3-D space inside and outside the balloon--your entire existence wouldbe contained on that 2-D surface.  But if the balloon inflated, you 2-D reality would grow in the context of the larger 3-D reality which was beyond 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.

No one is exactly sure how many dimensions there are.  There are theorys that suggest a certain number, such as the String Theory.  Though, I think that it is possible that there are an infinate amount of dimensions, but I don't think anybody will ever know.  If they do eventually figure it out I'm sure we will all be long dead by then.
