👤 whose
Whose discovery showed that the vacuum can create particle pairs?
Quick Answer
Julian Schwinger explained quantum electrodynamic effects in the 1940s and 1950s. His work helped show that empty space is physically active.
The Full Story
Julian Schwinger made major contributions to quantum electrodynamics in the 1940s and 1950s. One of the striking consequences of QED is that strong electric fields can produce electron-positron pairs from the vacuum. Schwinger’s calculations helped establish the precision and power of modern quantum field theory. He shared the 1965 Nobel Prize in Physics with Richard Feynman and Sin-Itiro Tomonaga.
