As you know, a very important problem in modern psysics, which arouses a great interest is the unification of all four interactions which exists in our Universe.
The four interactions are the next:
- gravity
- electromagnetism
- strong interaction(strong nuclear force)
- weak interaction(weak nuclear force)
Theese four interactions have to be unified, as possible as in a single consistent model, which will describe all known observable interactions existing in the Universe, at subatomic and cosmological scales.
Also as you know, we have a well defined field in modern psysics which is searching a such model and the name of this psysics field is Quantum Gravity (QG).
As we also know, we have a lot of concernings in elaboration of a Gravitational Quantum Theory, which will unify the General Relativity Theory with the Quantum Mechanics Theory.
In our days, we still don't know about the existence of a such theory, or could be a secret theory or unpublished one and this unknowing will exist till to the publication of a such unifying theory, or till to the proving that a such unifying theory can't exist.
But, what is the meaning of the unification of The General Relativity Theory with The Quantum Mechanics Theory ?
Thinking better, we could say that it's consisting in establishing of the logical and mathematical conexions between the General Relativity Theory and The Quantum Mechanics Theory.
So, it would consist of establishing of logical links and of mathematical equations which will describe the behaviour of elementary particles(explained by Quantum Mechanics) in the large frame of General Relativity Theory.
Is it possible to generate a such unifying theory ?
My answer is "Yes".
But, what is the base of my belief ?
It is based on the belief and it's a proved statement that the whole nature has an Internal Logic and we can put it on a logical base and in most cases on a mathematical base.
Could need this new thory of new concepts ?
It's possible.
But it's a positive fact that we can generate a Gravitational Quantum Theory.
