Why do some scientists say there are 11 dimentions?

They can't be explained. That's why the aforementioned string theory hasn't met a wide acceptance. There are other difficulties with string theory, but they would take a while to explain.

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.

Haven't you heard, its not the size, its what you do with it that counts.\nDimensions are a physical issue, spiritual entities are not bound to time and space.  Your soul is your why.  You body is more about how.

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.

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.

Unknown. We don't even know for certain how many there are now. There's at least three, but some scientific research indicates there may be as many as 11.

I might be missing something, but the cubic space something occupies is also referred to as it volume, where:\n\nfor a six sides regular box shape volume = heightxbreadthx depth\n\n( make sure all your measurements are in feet eg 1 foot 5 inches is 1 and 5/12 feet. \n\nHowever this formula is not true for a sphere or a trapezoidal box or a pyramid.  For whcih I'd recommend wikipedia or the old maths textbook as its hmmm, err 18 years since I last did all that stuff.

In theory 11 - one for each dimension.\n\nIn practice 3 - One to hold, one to turn, and one to rebuttal the whole time.  :-)

Our universe has 4 dimensions: up/down, back/forth, left/right, and time. According to well established theoretical physics, it is likely that our universe has more than 4 dimensions and could have as many as 11 (according to String Theory). As to why we can't see them, the leading explanation is that, at the beginning of the universe, all dimensions were curled up, but that at the time of the "big bang", 3 of the spacial dimensions and time unfurled, creating the universe we know to day.  The other 7 dimensions currently remain curled up in space where we cannot see them.

M Theory attempts to go beyond superstring theory and purport that the multiverse is made up of 11 dimensions. \n\nM Theory is based on mathematical calculations and not empirical data. However, M Theory does successfully account for every issue of all superstring theories (classical, quantum physics, etc) and mathematically postulates the number to be at 11. \n\nFor more information:\nhttp://en.wikipedia.org/wiki/M_theory

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

Yes. But, it's just a personal assumption, although it is an assumption held by the majority of people.\nThe most well known 4 dimensions are best described as width, length, depth and time. The order you list them does not matter, and there could be more - but humans have difficulty relating to more than these 4 (apart from imagining what they are like). The easist way to explain what a dimension is, is to say that you need all 4 to describe where an object is located.... eg, as a real world example I could tell you that I am located in a building at a certain cross-street (=length+width), a certain floor (=height) and at a certain time. You need all 4 dimensional descriptions to find me.\nTime is definitely the hardest of the 4 to properly comprehend. It's hard to think of time as being similar to length or width or height. It is special for sure to us humans, but that is only because our brain operates as a function of time... which means we are fooled into the perception that time 'moves'. Time does not move, no more than 'length' moves. You mind changes with time, just like the slope of a hill changes with height, but there is nothing to suggest that there is a certain special moment called 'now' that is somehow different to 'the future' or 'the past'. Read any scientific article on the topic if you really want to find out more about this 'special' dimension (see source link for an excellent read).

We live in a universe of observable/measurable quantities. For example, length, width, height, time, mass, etc.  If different quantities cannot be expressed in terms of the other quantities, they are "orthogonal" to each other - you can think of them as being separate dimensions. For example, on an X-Y graph, the x-dimension is independent of the y-dimension because you cannot express a "y" quantity as a combination of "x" quantities. \n\nSpace has 3 dimensions (length, width, height); time is a fourth dimension that cannot be expressed in terms of the other three.\n\nAn n-dimensional space is just a space that is characterized by "n" orthogonal quantities - quantities that cannot be expressed in terms of each other. To completely define the space/universe, you only need to specify "n" values - any more than that would be superfluous because the other values would be some combination of the other orthogonal quantities.\n\nExample: if we lived in a 4-dimensional space characterized by length, width, height, and time, all you need to do is specify those 4 quantities to uniquely determine any point in that space.  If we add another quantity (such as temperature) that cannot be expressed in terms of the other 4, we now have a 5-dimensional space that requires 5 quantities to be specified.

Actually, we ARE living in a multi-demensional world. We just PERCEIVE 4 demensions (including time). Most people think that another demension is 'another place' where you have to 'go to' when in fact, all demensions are interposed and coexisting in the same space; you just dont SEE / perceive them. Very much like the Jinn...they are THERE although you don't SEE them cuz they're vibration is way too high for your eyes to perceive. For example, if you can see THROUGH a coffee mug for example or through people, you are PERCEIVING more demensions. In other words, the more demensions you can 'perceive' the MORE you can SEE...either way, they're all THERE. \nHope that helps.

Well it depends on what you mean by dimensions. Some of the "dimensions" you list are parameters or variables. \n\nHowever, according to the standard definition of dimensions, we know about 4 dimensions (3 space and one time). There have been many attempts to unify the 4 fundamental forces of matter ("unified field theory") that have postulated the existence of more dimensions. This possibly started with the Kaluza-Klein theory, creating a 5th dimension. \n\nModern string theories and other theories require more dimensions. Many different types of string theory exist, and many different suggestions for the number of dimenions exist as well in string theory. However, no one really knows which if any of these theories are correct. The current leading string theory, M-brane theory, requires 11 dimensions.

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

there is no "forth" dimention, unless you mean back and forth, then it would just be forward :p\n\nanyway, the "fourth" dimention just refers to time.  There are 3 spacial dementions, and the 4th is time
