Born: 30 December 1935, Oslo, Norway.
Overview
Sjur Refsdal is a Norwegian astrophysicist recognized for foundational work in gravitational lensing. He is best known for proposing in the 1960s that time delays between multiple images of lensed sources could be used to measure the Hubble constant, a key parameter in cosmology. His ideas helped establish a method to connect geometric distances with observable time delays in lensing systems.
