why is it wrong or right?

you tell me

I understand what do u mean. ya I agree with u its such a chaos.

I understand where you're coming from on this. String theory does have its problems, but so do our other theories. Granted String theory is probably more problematic than most, from what I understand. I don't know enough about competing theories to comment fully however.
The requirement for 11 dimensions bothers me. I mean, just because we only experience 4 on a day-to-day basis doesn't mean that the other 7 don't exist. But it does bother me that the theory forces us to assume their existance without any previous evidence for it.

Now, I am curious, Farrokh... What is it about String theory that bothers you? What theories do you think we should be chasing up and working on instead?

this is easy, because string theory bases its existence on the theory of 1 dimensional strings, or are they strings in 1 dimension?

When the string vibrates transversally, well...it automatically becomes 2-dimensional.

Also, if the energy required to put tension in the string is so great, then where does this energy come from?
thus the theory inherently adds an extra force from the start, when the original goal was to unite the existing 4 fundamental forces.

lastly, it cannot even explain how magnetism or the magnetic force acts at a distance. (in fact none of the theories do a good job of this..., although QED gets a pat on the back for trying, but then on that theory, what exactly is a virtual photon but a mathematical construct?)

[Farrokh]

Many new theories developed and physicists are still working on new theories to complete their work. However, there are many theories which describe same phenomena and they don’t know which theory is the correct one or more accurate one. They can’t tell which one it the best because the definition of reality is not clear. For example, one of the mean objectives of these theories is to simulate the beginning of the world and they base their reasoning on creation of a clever creature like humans, which is not so well defined. Why isn’t it possible to have life in two dimensions? Is it just because our brains are adapted to three dimensions and it seems to us that life is impossible in two dimensions.
