Will you agree to the theory of more than 3 dimensions?

Answer 1

The reality is what we are sitting on is three dimension. Then we have the world of mathematic where imaginary numbers and variable make up the equations. Thus we are able to obtain imaginary multiple spaces.
A good example is probability densities where we can have n variables. Hence we can perform multiple intergration of n space. that would give an imaginary volume that could be applied to the solution of a real problem.
Another application is General Relativity where space-time is an imaginary geometrical space used to Relate gravitational intensities.

Answer 2

goring and others: There's nothing imaginary about spacetime. It's real. We really live in a 4D space according to General Relativity. Experiments support this.

Also, physicists often find things in equations that we don't see in nature (at that time). These things usually lead to predictions and then, if the theory is correct, experimental evidence. Take the existance of antimatter as an example. Anti-matter was predicted to exist by Paul Dirac BEFORE it was discovered. So was the neutrino. In the case of antimatter, the solution to the Dirac Equation (the Relativistic Schrodinger Equation for Quantum Mechanics) consisted of two possible answers to describe the electron-proton system. In one case, the solution exhibited the properties of the electron. In the other, it exhibited properties of what we know today as the positron. Since the solution for the positron was possible, then he predicted that it should exist in nature. It was found accidentally a few years later. That's how physics works. Neutrinos were predicted because to reconcile the equations describing neutron decay, we needed to add another particle to make the energies on both sides of the equation add up to what was measured by experiment. The only way to do this was to add another particle in the products. Then we started looking for that particle, and sure enough, it was there.

So when physicists talk about 11 dimensions (or any number of dimensions), they consider those dimensions very real things. It's not just the number of degrees of freedom. Adding extra dimensions to our theories could help solve some of the questions we have about our universe. So one of the issues that we have to ask is: where are the extra dimensions if they exist? We obviously don't see them, and since they would have an effect on several Laws of Physics that we've measured for centuries (such as gravity and electromagnetism), then where are they? They basically have to be very small or warped so that only experiments on small distance scales can measure them.

So don't fall into the temptation of dismissing extra dimensions as "only math." They'd have to be real for the theory to be correct.

Answer 3

Even if I don't agree it exists. It's evident, as told by others, that the 4th dimension is time. Kaluza-Klein theory exists in 11 dimensions.

String theory also predicts many dimensions. Although we cannot perceive those dimensions. We need to go to the level of 10^(-33) cm to reach those dimensions.

Answer 4

Its proven there is, in fact Stephen Hawking and other leading scientists believe there could be as many as 11 dimensions. Only 4 really significant ones and the rest really small minute dimensions with minor impacts to us. By the way the 4th dimension is Time. Time alters depending on the the effect of gravitity and speed. For instance the faster I go to the speed of light the more time slows.

Answer 5

The latest theory claims 11 dimensions, but I'm fine with the dimensions I know.

Answer 6

Yes, mathematicians work in multiple dimensions all the time. Time is the 4th dimension, and string theory (the supposed theory of everything) requires 11.

Answer 7

I have experienced 6 dimensions that I'm sure about so yes.

Answer 8

String theory anyone?

Answer 9

Yes, definitely.

Answer 10

All I need is three. Time is just a state of mind.
