Stephen Hawking (1942–2018) was a renowned British theoretical physicist, cosmologist, and author known for his groundbreaking work on black holes, cosmology, and the nature of the universe. Despite being diagnosed with amyotrophic lateral sclerosis (ALS) at the age of 21, which gradually paralyzed him, Hawking made significant contributions to theoretical physics, particularly in the study of black holes and the origin of the universe. His book “A Brief History of Time” (1988) brought complex scientific concepts to a broader audience and became an international bestseller. Hawking’s research on black holes and the theoretical prediction of Hawking radiation revolutionized our understanding of these celestial objects. He remains one of the most influential scientists of the 20th and 21st centuries, inspiring generations with his intellect, perseverance, and scientific insights.
