👤 whose
Whose work predicted the existence of the positron before it was seen?
Quick Answer
Paul Dirac predicted antimatter in 1928. The positron was discovered a few years later in 1932.
The Full Story
Paul Dirac’s relativistic equation for the electron, published in 1928, produced solutions that implied the existence of antimatter. The first antimatter particle confirmed was the positron, discovered by Carl Anderson in 1932. Dirac’s prediction was a major triumph for theoretical physics and helped shape modern particle theory. His work showed that equations could reveal new particles before experiments did.
