How many dimensions are there in universe and name them?

Dimension of a mathematical space or an object can be defined as the minimum number o f coordinates needed to specify any point within it. We live in a three-dimensional world, and sometimes scientists consider that time as a fourth dimension. But some theories in physics such as string theory, predict that there are many, many more dimensions may be 10 or 11.

Dimensions are simply the different facets of what we perceive to be reality. We are immediately aware of the three dimensions that surround us on a daily basis – those that define the length, width, and depth of all objects in our universes (the x, y, and z axes, respectively). Before we consider the dimensions, we need to consider the basic unit of all things in the universe: a point. the concept of a singular finite point.  We start from that point. Here’s the quick description of each dimension.

Dimension No. 1: A line. Any line. A line that stretches from one point to another, without any width to speak of. Basically this entity does not really exist in the way we perceive the world, as everything in our practical view has tangible length and width. No matter how it is small.  It’s just an abstract concept.

Dimension No. 2: A plane. Length and the width of line. Imagine a plane it is easier to imagine it rather than an impossibly thin line. But it still can’t quite exist in real world. Even a sheet of paper, must has some degree of depth or thickness.  But you can image a flat surface viewed straight on: a floor, wall, tabletop, photos, even the TV with the images.

Dimension No. 3: Space. That’s where we live. Just as a line becomes a plane when you tack onto it from the side, a plane becomes an object in our world when you “inflate” it from another angle. We see everything with length, width, and depth — but that’s it. The third dimension involves depth (the z-axis), and gives all objects a sense of area and a cross-section. The perfect example of this is a cube, which exists in three dimensions and has a length, width, depth.

Well, that’s all we know yet. But according to scientists, beyond these three lie the seven dimensions which are not immediately apparent to us, but which can be still be perceived as having a direct effect on the universe and reality as we know it.

Dimension No. 4: The Time. Scientists believe that the fourth dimension governs the properties of all known matter at any given point. Along with the three other dimensions, knowing an objects position in time is essential to plotting its position in the universe. For example picture yourself at this very moment. Now, imagine yourself five minutes ago — or five days, or five years, To grasp a world observed from the Fourth Dimension (as ours is from the Third), picture each of these variations of yourself as physically connected along the line of time.

Dimensions No. 5: According to Superstring Theory – which is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny super-symmetric strings – the fifth and sixth dimensions are where the notion of possible worlds arises. If we could see on through to the fifth dimension, we would see a world slightly different from our own that would give us a means of measuring the similarity and differences between our world and other possible worlds.

Dimension No. 6: In the sixth, we would see a plane of possible worlds, where we could compare and position all the possible universes that start with the same initial conditions as this one (i.e. the Big Bang). In theory, if you could master the fifth and sixth dimension, you could travel back in time or go to different futures.

Dimension No. 7:  In the seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time.

Dimension No. 8: The eighth dimension again gives us a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).

Dimension No. 9:  In the ninth dimension, we can compare all the possible universe histories, starting with all the different possible laws of physics and initial conditions. In the tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.

Dimension No. 10:  At this level, everything that is imaginable and possible exists!  (The third eye! Ultimate!)

According to string theory, the universe has a total of 26 dimensions as opposed to the four dimensions it possesses under the special and general relativity theories.

Apparently, the existence of these additional dimensions which we cannot perceive is necessary for the String Theory  –  in order for their to be consistency in nature. The fact that we can perceive only four dimensions of space can be explained by one of two mechanisms: either the extra dimensions are compacted on a very small scale, or else our world may live on a 3-dimensional sub-manifold corresponding to a brane, on which all known particles besides gravity would be restricted (The Official String Theory Web Site).  In theoretical physics, a brane – (membrane) is an object which can have any number of allowed dimensions. Branes are most popular for their presence in string theory, where it is a fundamental object, along with the string. Branes were hypothesized as part of string theory in the late 1980s.

Scientists believe that peering back through time, using telescopes to observe light from the early universe (i.e. billions of years ago), they might be able to see how the existence of these additional dimensions could have influenced the evolution of the cosmos.  In short, it is an attempt to explain how all known forces within our universe interact, and how other possible universes themselves might work.

Only, these dimensions (from 4th) are not accessible to us. We do not see them. Maybe these dimensions are subatomic, tiny, and smaller than particles inside of an atom. And if someone could somehow travel along these other dimension, it would take somewhere else entirely. Maybe it is possible that the other dimensions are exists which we are not predicted.The other dimensions are where the deeper possibilities come into play, and explaining their interaction with the others is where things get particularly tricky.
