To eleborate on the previous answer there are at least 10 spacial dimensions and 1 dimension of time. There appears to be some truth behind string theory with respect to the quantum world, explanation and visualization follows. Take a box, the box represents the 3 spacial dimensions that we know; width, heigth and depth. Now take any top corner of the box and go to any other corner. You will see you can do this 7 times. Now rather that imagining a straight line between each of those corners, imagine them folded onto themselves. This appears impossible because we are big and can only see 3 dimensions and we can perceive time. But the quantum particles see 7 dimensions of space clearly and our 3 dimensions less clearly. To illustrate this, you are a quantum particle stopped at the road in outter space. You see 7 major highways, and you can barely see 3 trails (our 3D space). You will take one of the highways, but whilest you are on one of the 7 spacial dimensions, you will still be within 3D space (as if you saw and took a shortcut) which the macro i.e., atoms cannot see or do. Technically within 4D space (3D + Time). So a quantum particle is at all times in 5 dimensions whereas we are in 4 dimensions. This is why quantum appears random from 3D analysis because they are always moving on 5 planes.

Does fourth dimension really exist?
Yes. The 4th dimension is time. According to String Theory (which is unverified), there may be as many as 11 dimensions, but dimensions above the fourth are hypothetical.
How many dimensions in a cone?
A cone needs a three dimensional space in which to exist but it's not a solid, it's a two dimensional surface.
How many dimensions there are?
Depends what you mean by "dimension", since there are several definitions of the word. In mathematics, there are an infinite number of dimensions, since (for the most part, except in geometry) dimension simply refers to an array of numbers or co-ordinates. It is therefore possible to construct a graph (or build a co-ordinate system) with any number of "dimensions". Many branches of mathematics deal with these higher co-ordinate structures. In geometry, dimension has a similar definition to the physical sense, but again an infinite number of dimensions are available, since these do not necessarily refer to "real world" applications. Euclidean geometry deals with 2-dimensional spaces, while non-Euclidean geometries deal with 3, 4 or more "dimensions" of object.In physics (the sense I think you mean) the question is still somewhat open. Originally we believed there were only three, but Einstein demonstrated that time was another dimension, and thus established that there were four (three spatial and one time). Recently, certain problems in physics have suggested that even "higher" dimensions exist. These dimensions are purely (as far as we know) spatial, but are "wrapped up" tightly around themselves, and are thus invisible and undetectable in most situations.Depending on which theory you go for, there could be five, eight, or even eleven dimensions out there. The current strongest candidate (but far from proven yet) is M-Theory, which holds that there are 11 spatial dimensions, wrapped up into what are called Calabi-Yau manifolds, like little knots at every point in space-time.These dimensions will never be "viewed" by human eyes, even if proven or otherwise detected, since our entire sensory system is built around 3 perceivable spatial dimensions, and thus we would have no frame of reference to understand what we would be seeing.We operate in three dimensions, plus time. That's four. But there can be more. In mathematics, any number of dimensions can be managed (or attempted, at least). Theoretical physicists are currently working with a dozen or so in what are called manifolds in an attempt to understand reality as we know it. The number of dimensions will vary as the individual who is manipulating them or working in them. Usually the x, y, z axes and time are sufficient for most of us.This is an interesting question in contemporary physics. Albert Einstein described the universe as existing in 4 dimensional space-time, but M-theory (an extension of string theory) postulates that there are 11 space-time dimensions.(P.S. How many dimensions are there?)One. Unless in the future humans create a device which can create others.
How many dimensions does a solid body have?
It has three dimensions.
How many dimensions are there in a box that has a area of 88 cm?
The area of the box is immaterial. If this is just a normal math question then the answer is 3 dimensions. Length Width and Depth. If is a question ref mathematical theory, then Space and Time bring the answer upto 5, but for this you would have to be doing a degree.
Does fourth dimension really exist?
Yes. The 4th dimension is time. According to String Theory (which is unverified), there may be as many as 11 dimensions, but dimensions above the fourth are hypothetical.
How many temporal dimensions are possible within String Theory?
String Theory (as its predecessors Relativity and Quantum Mechanics) has only one dimension of time. However it has many more dimensions of space than its predecessors (both had 3 dimensions), as the simplest version of String Theory must have 10 dimensions of space, while more complex versions require more (with no defined upper limit known). The big question is "Why can't we detect those additional 7+ dimensions of space that must be present if String Theory is true?".
How many dimensions do atoms have?
[At least] Three. There could be more if string theory or the theory of branes proves to be true.
How many dimensions are there outside of earth?
At the moment we know of 4, the 3 dimensional you know of and space as the 4th. However it is theorized to be 11 dimensions through the string theory. Although the string theory is still under heavy development.
How many dimensions are respectably embraced by science in 2012?
Depends what you mean by "respectably." M Theory, a type of string theory, requires the existence of eleven dimensions in which the strings can vibrate. If you consider M Theory to be "respectable," then the answer is eleven. If your view of M Theory is that, "It's so bad a theory that it's not even wrong," then you might say that eleven dimensions is not respectable.
What is the status of string theory?
No. not necessarily. Not one scientist has proved the string theory to be true so you can't say that its true or fake. Although I don't believe in the string theory anyway. There are also many versions of the string theory. I don't think that quantum particles like quarks are infinitesimal one-dimensional "string-like" objects. So in conclusion the string theory is not real nor is it fake. We don't have enough information about these particles and so we don't know whether the string theory is true or not. But remember there are many versions of the theory.
How many realms of reality are there?
If you're christian, one. If you're naturalist, I've heard from one, ours, to a multiverse with infinite. One particularly strange theory is that there are infinite 'brane worlds' in a string. That theory came from string theory, to m theory, which also states there are eleven dimensions. Many of the worlds greatest minds can't explain it properly.
Does 4D exist OR is 3D the limit of Dimensions?
Mathematically, you can have as many dimensions as you want. Our "real world" seems to have only 3 dimensions. While there are speculations that other universes - or parts of our Universe - may have more or less dimensions, for now, these are just speculations. According to string theory, our Universe actually has 10 or 11 dimensions, but only 3 of those appear on a large scale - the others will only have an effect on very, very tiny scales.
How many directions are there when one is in Space?
Conventional knowledge has three spatial dimensions (and on of time) . String theory has about six more spatial dimensions curled up so tiny we have not been able to unravel them.
How many dimensions are there know to man?
Geometrically speaking, man knows of three dimensions; height, width, and depth. As far as dimensions with reference to different universes or plains of existence goes, they only currently exist in theory.
Are there 14 dimensions?
That depends upon the context of your question. Mathematically speaking you can have as many dimensions as you want, and work with them; so a 14-dimensional vector space is possible in mathematics and can be worked with. But mathematics is also used to model the world: Zero dimensions is a point One dimension is a line Two dimensions are a plane Three dimensions forming length, width and depth form the space we live in. Einstein extended the three dimensional space in Relativity by considering time as a fourth dimension creating a space-time model to explain things like gravity. More recently there have been attempts to unify the different theories about how gravity, quantum effects, nuclear forces, etc work. As a result the three dimensions has been expanded by String Theory to many more dimensions. For example Super string theory has 10 dimensions and Bosonic string theory has 26. Supergravity theory has an upper limit of (and preference for) 11 dimensions, whilst general gravity theory allows any number of dimensions (including 14).
How many diminsions are there?
There are three visible spatial dimensions. Time is often also considered a dimension. Some forms of string theory postulate an 11 dimensional space.
