Why gravity is incompatible with quantum theory?

Answer 1

It is not, only seems that way because the explanation created to descibe gravity is incorrect, even Einstein was not satisfied with his theories regarding gravity, he totally ignored the one unifying force that makes all 4 forces fit together, EM (electromagnetic)-electricity!

Answer 2

Combining wide-unfold Relativity and quantum mechanics is an lively container in theoretical physics observed as "quantum gravity". there is no very final concept of quantum gravity, yet a large style of artwork has been achieved and there's a few fulfillment---working example, that is possible to predict that Black Holes explode, and how and why and while that occurs. i think of the "deep" reason that quantum gravity is a concern is that as a rule Relativity, the form of area itself is dynamic---to describe the form of area demands a awareness of gravity, particularly a awareness of the area of all the mass and power. Quantum mechanics, even relativistic quantum mechanics, starts off out with a fastened background geometry, and the a lot and energies flow around in this fastened background. the two procedures are basically distinctive, from the 1st actual web site of the textbook.

Answer 3

That's the Holy Grail of physics now, to unite all four forces together. Problem is, how can you bring together three forces which need barely any matter at all to work together with the fourth force which only happens when huge [by comparison] amounts of matter coalesce?
It is not that it is all incompatible, it's just no one has come up with the right equations to completely describe it yet. We need more technology and more time that's all. Write your congressman and get them to fund the SSC project. Only with higher energies can we understand how the forces interact on a bigger scale.
