String theory is a current candidate for the theory of everything, which is a way to describe natural forces and matter in a mathematical equation.

String theory is also an attempt to unify Relativity and Quantum Mechanics. These are now very different, relativity describing the world on galactic scale and quantum mechanics on atomic scale. unifying the two would give us increased knowledge of the Universe.

Could String theory mean that other realities do exist.??

I'm not sure what you mean by this question. If by other realities you mean parallel universes that mirror our own except for minor variations, I don't think String Theory is meant to answer that. String Theory endeavors to answer questions about our own universe: how it's made and how it works. There are multiple dimensions associated with String Theory, but these are not to be taken in the entertainment sense of the word dimension. Whether we talk about 4-dimensional space time or 10-dimensional space time we're still just talking about the universe we live in. The extra dimensions may simply be too small for us to even measure, or maybe too large. A fly floating in the middle of a blimp might suppose that the blimp's space is infinite, but a person standing on the ground looking up can clearly see it's borders.

My opinion is that the only reality that exists is reality.

This a very simplistic question, but for example your example of say the 4th dimension would seem require a different kind of math scale to render understandable the physical rules of this "dimensision.
Base ten is what we work with in our reality/dimension, plus it's highly likely our gravity and electrical theories would be shattered within a "new" base system.

Notlike I'm an expert in these higher functioning equasions, but it seems to me the closer partical physics moves forward,the more possible Metaphysical mechanics becomes explainable as a "norm" of unknown/ previously unmesurable dimentions WITHIN our own reality come to light.

Not so much as parellel realities but undiscovered complinentarily portions of our own dimension we're just now figuring out are there and will be able to utilize in the near future.

But like I said....I'm just an amature with too much time on her hands! Grin....

There are infinite deminsions.

I agree that there are infinite dimensions but not in the sense of the word that you are using. there are ,according to the quantum theory, other universes apart from our own. these universes are referred to as quantum universes. what quantum theory states is that every time something that involves chance happens in a universe another universe is created from our own in which the other chance happened. for example if you flip a coin in our universe and it lands on heads then there is another universe that has split off from ours that the coin lands on tails. everything else in the quantum universe remains the same except for the outcome of the coin toss. and every time that something happens that involves chance then another quantum universe is created. the quantum universes are infinte because you can divide time down an infinte amount of units and in every unit of the superdivided time something that involves chance is going to happen.

of course this whole quantum universe thing disagrees with another theory which has proven to be correct called chaos theory. it states that everything that seems to happen because of chance actually happens because of something else. such as the coin flip, it is seemingly complete fifty fity chance but the outcome (heads or tails) is actually affected by things in the environment around it such as wind speed or place on your thumb that the coin was launched off from.

so for the quantum universe theory we either have to eliminate it or somehow reconcile it with chaos theory.

2 dementions one antimatter and the other matter. the matter demention is so dense it shrinks, leaving voids like swisscheese. when this occured time and gravity began in the matter demention. Now the dementions have a coplaner side. The voids in the matter demention are free floating under great pressure. when a void makes contact to the coplaner side the antimatter is exspelled into the antimatter demention. When this happens the antimatter dementions gains. But if a free floating piece of matter were in the void it would be exspelled into the antimatter demention. This tiny piece exploded violently, and since time and gravity at that instant did not exsist, matter travel through out the antimatter demention instantly. This event created our universe and time and gravity that related to the absolute co-ordinate of the event.

crazy maybe ! a point in space can not exsist without a absolute cordinate. a point has no dementions just location. If you attach a radian to the point with a power of say 3 the radian has length but no measureable width.If you dublicate this radian infinately about the point, it will become a solid sphere with a diameter of the 6th power. Now allow the radians to be elastic, the point is held by the absolute co-ordiante. As the sphere moves or vibrates about the point its center slides within its diameter. The radians length vary acording to point location and the spheres shell. if the point moves out side its shell diameter it is no longer held by the absolute co-ordinate. it can snap instantly any where in the time space continuim. appearing out of nowhere lightyears away, because it lost its relation to time and space. When it reapears its center is back within it diameter. It is instantly given a co-ordinate by the absolute and starts aquiring time in space. Remember it can't return until it reenters its diameter.

Now we have a electron, protron and a nucleus. The radians on the electron point inward, the radians on the protron point outward. The nucleus has no charge but holds its protrons. The electron held in orbit by the protron ,the nucleuse acts like the absolute co-ordinate. If a electron escapes its orbit it becomes a free electron, does it relate to time and space. Or could it reappear anywhere in the continuim. We know electrons move about ,but is it the same electron moving down say a condutor. Or can this charge be from anywhere out of time

Liked rcoons depiction...as good as any other and better than pointmasses or fights between more positive and negative matter after tunneling(hawkins the why of those processes never properly explained)and a slow start with sudden inexplicable acceleration.

another track in the trousers of time...that come together again. so everything that happens stays happened and could more or less be attributed to a same cause.
A fractal has a finite surface but an infinite circumference. and a very simple formula to start with

but frankly imo i think the maths is confused with the reality or some would say that properties in real are confused with dimensions.

the original question.
it was never intended to be the answer to unification it just tries to explain such questions as infinite space, the edge that is not there and what properties the smallest, so most fundamental and earliest wavicles should have. could they have been in the beginning etc.

higgs and god particles however seem to be inextricably linked to unification.

Go to Absolute Astronomy and in topics look into Quantum Relativity and see in there 16 dimensions effecting a mass traversing a space in a specified period of time.
