The first though is that gravity is the result the deformation of space.time due to a mass. But this does not answer why a mass can deform it. This must imply some particle that causes it (graviton?). This is what they are investigating and whether an anti-particle also exists. But this has not yet left the blackboard and the laboratory.
Until now all the atoms and particles that were previously scientifically predicted have been found.
Because of this i post it with an ?, but there are several hypothesis about it (no theories in science about something not independent repeatable, no confuse the meaning of theory in science, a theory in science is eg, the one of Einstein about relativity).
Nobody knows what gravity is yet.

In some theories like conformal gravitation the graviton doesn’t exist.
