Robertson (Howard P. Robertson)

Howard P. Robertson was a mathematician and physicist known for his contributions to cosmology and general relativity. He developed the Robertson-Walker metric, a mathematical description of the universe's large-scale structure, which shows that the universe is expanding over time. This metric forms a key part of modern cosmological models, describing how space itself stretches and evolves. His work helps scientists understand the universe's origin, development, and overall shape, providing a foundational tool for studying the cosmos within Einstein’s theory of gravity.
