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.
A particle and anti-particle are two types of subatomic particles that have the same mass but opposite charge. They are also known as matter and antimatter, respectively.
Particle and anti-particle are created through a process called pair production, where a high energy photon or other particle interacts with matter and produces an equal amount of matter and antimatter particles.
When a particle and anti-particle meet, they annihilate each other, converting their mass into pure energy in the form of photons. This process is called annihilation.
The study of particle and anti-particle is important in physics because it helps us understand the fundamental forces and interactions between particles at the subatomic level. It also has potential applications in fields such as energy production and medical imaging.
Yes, the annihilation of particle and anti-particle can be harnessed to create energy. However, it is currently not a practical or efficient method of energy production due to the high energy requirements and difficulties in containing antimatter.
