Stephen Hawking was one of the most renowned theoretical physicists and cosmologists of all time. Born in Oxford, England, in 1942, he studied at the University of Cambridge, where he developed groundbreaking theories on black holes and the origins of the universe. Despite being diagnosed with amyotrophic lateral sclerosis (ALS) at the age of 21, which left him almost entirely paralyzed, Hawking continued his scientific work with unwavering determination. His book "A Brief History of Time" became an international bestseller, making complex scientific concepts accessible to the general public. Hawking's contributions to science include the idea that black holes emit radiation, now known as Hawking Radiation. He also played a key role in advancing our understanding of the Big Bang theory. Beyond his academic achievements, Hawking was a strong advocate for space exploration and artificial intelligence, warning about its potential dangers while promoting its benefits. His legacy continues to inspire scientists and the world at large.
