Supergravity is considered to be a relatively new theory that can combine the different theories that have already been stated before. It combines the various principles that are being followed in supersymmetry and also general relativity.
Supergravity states that the different particles of the atom will be based on particle symmetry. With particle, symmetry comes gravity and all of the other potential forces that will have an effect on what people are going to experience. All of the other interactions of the particles that are found in atoms can be based on this. There are still some people who think that this theory is promising.

Super-gravity is a type of quantum theory. This theory includes consideration of gravity along with the other fundamental forces. These other three are the electromagnetic force, the weak nuclear force, and the strong nuclear force.. Super gravity is a field theory proposing that elementary subatomic particles and their interactions are based on the particle symmetry.
This is also known as supersymmetry and that includes the gravitational force along with the other fundamental interactions of matter. In essence, super-gravity combines the principles of supersymmetry and of general relativity into one field theory.
