This class of particles corresponds to the negative energy solutions of Dirac-type equations, and the Feynman interpretation of them states that they can be viewed as their counterparts moving backwards in time. Big Bang theory states that these were dominated by their counterparts after the Grand Unification Epoch, and a normal particle is known as "self-adjoint" if it is equivalent to one of these. For ten points, name the type of matter that annihilates normal matter and may be best typified
