Antimatter and Repulsive Gravity
The existence of antimatter was first predicted by Paul Dirac in papers published from 1928 onwards. Classical physics only allowed systems to have positive energy. But Dirac’s new theory of relativistic quantum mechanics allowed for a particle with negative energy solution, as a counterpart to the familiar positive-energy electron. After ruling out the possibility that this particle was simply the proton – which has a hugely greater mass – Dirac predicted the existence of a new particle with the same mass of the electron but with a charge that was positive rather than negative. That particle was found experimentally on 2 August 1930. Carl Anderson was observing the trails produced in the particle shower that was created in his cloud chamber when cosmic rays passed through it. His observations included a particle with the same mass as the electron but the opposite charge – its track bent in the “wrong” direction in a magnetic field. Anderson coined the name “positron” for his new discovery. In 1933 Dirac went on to predict the existence of the antiproton, the counterpart to the proton. It was discovered in 1955 by Emilio Segrè and Owen Chamberlain at the University of California, Berkeley. It’s now understood that all particles have an equivalent antimatter particle with opposite charge and quantum spin – although some are their own antiparticle. However hardly any antimatter is seen in the observable universe, and why there should be vastly much more normal matter is one of the great unsolved problems in physics.

ANTIMATTER AND REPULSIVE GRAVITY
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.Can gravity be a repulsive force? The fact that objects move a lot in the universe and that the universe is expanding,can imply that gravity is a repulsive force that increases with distance.. so the farthest objects repel us more. The mutual repulsion of the particles may cause similar motion as if due to gravitational attraction.The leading theory to explain the accelerating expansion is the existence of a hypothetical repulsive force called dark energy. "We are replacing an unknown force caused by an unknown element with the repulsive gravity of the well-known antimatter.
