Would a Unified theory like string theory or quantum gravity be intrinsically tied to empiricism?
It would depend if the theory were experimentally or obsversationally validated; in the case of String Theory (which is a theory of quantum gravity), more accurately called M-Theory (M-Theory unifies all five variants of String Theory into one with 11 dimensions), experimental validation is out of the question. Experimental validation would require an enormous particle accelerator; the scale of this accelerator simply cannot be imagined. Observational validation is unlikely as well: M-Theory predicts that we should observe magnetic monopoles (magnets that we have are dipole, meaning that they have a North and South end); however these have not been observed and are unlikely to be observed: they are not expected to have a very high density, meaning that the universe is too large and monopoles too few in number. Although it would be great if validated, it is highly unlikely to ever happen.
What else can I help you with?
Is string theory the closest theory to a unified field theory?
Yes, so far it is- string theory explains many of the unresolved fundamental problems of our century, such as the opposition between Quantum Mechanics and Einstein's theory of general relativity.
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.
What are some words in science that start with the letter q?
Quantum theory, Quantity, Quanta of light.
What is quantum free electron theory of metal?
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.

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.

When did Stephen hawking come up with Quantum gravity?
Stephen Hawking worked on quantum gravity throughout his career, but one of his notable contributions was made in the 1970s, when he investigated the quantum effects near black holes and proposed theories to explain the relationship between quantum mechanics and gravity.
What is loop quantum gravity?
It is an attempt to merge quantum mechanics and the General Theory of Relativity.For more details, I suggest you read at least the overview in the Wikipedia, article "Loop quantum gravity".

Why is string theory so attractive to those seeking a unified field theory?
String theory attempts to unify the general theory of relativity and quantum mechanics, two prominent and proven theories that are the most incompatible. If gravity and the electro-weak/strong interactions could be combined, that would create the unified field theory or theory of everything.

What is Quantum Gravity?
In a word. No. Grand unification is also commonly called the Theory of everything. Which in a sense, there would exist an equation of a set of equations that every other physics equation can be derived from. A quantum theory of gravity would only help to better blend quantum mechanics and classical mechanics, not necessarily leading to a theory of everything, though it would be another step toward it.
What are the alternatives to string theory?
Some alternatives to string theory include loop quantum gravity, quantum field theory, and causal dynamical triangulation.
