How would you explain an individual particle with string theory?
An individual point particle in the standard model is described in string theory as a mode of vibration of a string. If for some reason the mode of vibration of the string changed, the particle would change to a different one.
What is the difference between a model and a theory?
a model is different than a theory a model is an actually picture or structure of something a theory is what people might think about something
What does the alleged discovery of the higgs boson particle mean when applied to string theory?
It doesn't mean much. The Higgs Boson is only necessary for the Standard Model to be correct; the Standard Model excludes gravity, and String Theory is a theory of quantum gravity. The two are separate from one another.
What is the leading Grand Unified Theory?
It depends on what you mean by leading. A few good candidates are string theory, the standard model and loop quantum gravity.
Is the string theory correct?
Yes, no, maybe, who knows. String theory may be correct, or it may not. We really don't know enough to know for sure yet. It doesn't really explain anything we can actually observe any better than the Standard Model does, so a fair number of physicists regard it as a not-particularly-useful form of mathematical ... erm, "exercise."
What question did the string theory answer?
String theory answered the question of a T.O.E - Theory of Everything. It explained many unresolved problems like the opposition of Quantum Mechanics and Einstein's theory of general relativity. It also includes gravity in the Standard Model and unifies the 4 fundamental forces- gravity, electromagnetic, strong nuclear and weak nuclear

Three theories on the evolution of the universe?
Steady State (Hubble) Big Bang (Standard Model) Brane Collision (String Theory)
Is it true that when scientists discovered that the speed of light changes they realized there could be 26 or more different dimensions?
No. The speed of light does not change. In fact recently the definition of the meter has been changed so the speed of light is exactly 299792458 m/s, so if anything the meter would change. As for the 26 dimensions; this is a result from a certain model within String Theory called the Bosonic String. This model however has several shortcomings, but is still being taught today at Universities because it provides a nice introduction to String Theory. It was surpassed by the Fermionic String which demands 10 dimensions. Currently the best model is called M-theory and it requires 11 dimensions.
How does the theory of quantum mechanics apply with string theory?
String theory is one of the leading candidates for a theory of everything, that is, a theory that unifies all 4 basic forces of nature, viz, gravity, the electromagnetic force, the strong force and the weak force. The last 3 forces mentioned above are described by quantum mechanics. This is the link between quantum mechanics and string theory. ps- If you believe in watertight definitions, then quantum mechanics is all the quantum theory till Dirac's equation. I'm taking quantum mechanics as the theory of the small as such, that is, all of the phenomena of the small from Plank till the standard model and beyond.
Is string a solid or liquid or gas?
If the question is about everyday string we might use for example to tie something, it is a flexible solid. If the question refers to string theory, a state of matter in which it would be categorized would simply not be applicable. The reason is, material states such as solid, liquid, gas, describe manifestations of forces between entire atoms or molecules; since string theory relates to a model representing a particle, its state would not, in isolation, represent collective behaviors of larger structures of which it is only a component.
What will be the theory after the quantum theory of light?
There is unlikely to be a successor to a quantum theory of light, by the definition that the quantum theory of light is that "Light is made up of discernible particles", has very strong evidence to support it, and no alternative explanation has yet been found to explain such effects as the photoelectric effect.If you mean quantum electrodynamics, the section of the standard model of particle physics that explains light, electricity and magnetism, and therefore the standard model of particle interaction, then the only answer is that absolutely nobody knows. In fact, finding a successor to the standard model, which despite being one of the best theories ever developed is full of more holes than the titanic if taken as a theory of everything, is one of the biggest deals in all of science.One possible successor to the theory of quantum electrodynamics is the section of superstring theory that explains electromagnetism, but there are many who don't think string theory will be the answer to physics' problems, and certainly string theorists have yet to find any strong evidence supporting their theories.
