When was the modern electromagnetic force first unified with the weak force?

PhysicsFundamental forces

Quick Answer

In 1967–1968, the electroweak theory was developed independently by Sheldon Glashow, Steven Weinberg, and Abdus Salam. It unifies electromagnetism and the weak force.

The Full Story

The electromagnetic force was unified with the weak force in the electroweak theory developed in the late 1960s. Sheldon Glashow proposed an early unified model in 1961, while Steven Weinberg and Abdus Salam published the more complete theory in 1967 and 1968. Their work showed that two seemingly different forces are aspects of one underlying interaction at high energy. The theory later became one of the central pillars of the Standard Model.
