Different Dimensions?

Question

What are the 5th, 6th, 7th, 8th, 9th, and 10th dimensions? I know that the 4th is time.

Answer 1

theres the 4 we know and live in - space-time. The M-theory mathematics are basically a unification of the 5 different String Theory equations...that 11th dimension that was added by M-theory basically makes the strings look like rippling surfaces (membranes) instead of just a string. The extra 7 dimensions around us are compactified, ie miniscule to the point where we cant percieve them, but do have an effect on the quantum world. Theres no point in naming them, since we dont percieve them, and they are simply variables in the p-brane equations, ie the value of p can range from 0 to 9, equating to 10 different space dimensions + time. This was long and rambling i'm sorry...they dont have names is the answer. And actually i forget it was on my icon but the picture on it is of a 3 dimensional Calabi-Yau space. Now imagine that picture but in 7 dimensions and those are the extra ones :) have fun and good luck with that :)

Answer 2

The first 3 are spatial (length, width, depth) and the fourth is time. The others don't have true spot-on definitions.

The other 6 are called 'internal degrees of freedom' and are related to the number of fundamental symmetries present in the physical world at the quantum scale. The equations that physicists work with require these additional dimensions so that new symmetries can be defined that allow physicists to understand physical relationships between the various particle families. They think these are actual, real dimensions to the physical world, only that they are now 'compact' and have finite sizes unlike our 4 dimensions of space and time which seem almost to be infinite in size. Each point in 4 dimensional space-time has another 6 dimensions attached to it which 'particles and forces' can use as extra degrees of freedom to define themselves and how they will interact with each other. Do not confuse them with 'hyperspace' because the particles do not actually 'move' along these other dimensions. They are not 'spatial' dimensions, but are as unlike space and time as time is unlike space!

Hope this was what you were looking for...Blessings

Answer 3

In general, whenever n-dimensional space is described, all but one of the dimensions is a spatial dimension & the last is time.

The trouble is that there isn't any real way to test the dimensionality of the space we occupy - we perceive it as 4 dimensional space, but this does not guarantee that this is the case. If our perceptions are constructed on motion in 3 spatial dimensions, it may just be physically impossible for us to perceive or even imagine movement in other spatial dimensions. A lot of string theories rely on mathematical tricks involving greater dimensional space, and a substantial portion of the physics community frowns on them because they can't be subjected to experiment.

Answer 4

That's a lot like asking "what color is up?"
Modern physics makes more sense if additional dimensions are assumed, but to the best of my knowledge, there is no actual proof of them, or indication of how to interact in those dimensions.
One thing though... if we do assume more than 3 spatial dimensions (multiple temporal dimensions gets wacky fast), it seems we also have to have something 'holding' our reality, much like objects on a table are held there on a 2D plane. Otherwise the conservation laws would not apply.

Answer 5

The 6th dimension is where my socks disappear to.

Answer 6

check a documentary called the -elegant universe-in three parts ,about string theory and M theory the last one is called .welcome to the 11th dimension
