Hi friends,
What is the need for the existence of an antiparticle for a particle?

jhmar said:Dirac predicted the existence of the positron before it was confirmed by experiment.
First Dirac constructed a theory based on a number of unexplained experimental observations, the theory predicted the existence of positrons. Experiments precede prediction theory see-

But there was a conundrum. The equation had two solutions, one representing the electron, the other representing its opposite, a particle with negative energy and positive charge, that had never been seen or suspected before.
jhmar said:This is very odd. I don't know what "experiment" you are claiming that preceded the prediction of antimatter
The article begins with-
'Experiments had shown that classical physicists could not explain the behaviour of atoms'.
Dirac devise a mathematical theory to match these experiments and that theory predicted (numerically) anti-matter.
