Stephen Hawking, who brought the cosmos to millions, dies at 76

Stephen Hawking, the celebrated British theoretical physicist whose work transformed our understanding of black holes and the origins of the universe, and who defied a devastating illness to become one of the most recognisable scientists of his age, has died at the age of 76, prompting tributes from around the world.

Hawking's scientific contributions were profound. His work on black holes, including the revolutionary insight that they are not entirely black but emit radiation, now known by his name, reshaped theoretical physics and helped bridge the gap between the physics of the very large and the very small.

Diagnosed with a motor neurone disease in his early twenties and given only a few years to live, Hawking defied the prognosis for decades, continuing his research and communicating through a computerised voice system after he lost the ability to speak. His resilience made him an inspiration far beyond science.

He became a global cultural figure, in large part through his best-selling popular book on cosmology, which brought complex ideas about time, space and the universe to millions of readers and made him a household name. He appeared in popular television shows and was celebrated as a symbol of the power of the human mind.

Hawking combined scientific brilliance with a wry wit and a gift for communication that made abstract physics feel thrilling and accessible. He spoke out on issues from the future of humanity to artificial intelligence and the exploration of space.

Tributes poured in from scientists, public figures and admirers who celebrated both his intellectual achievements and his extraordinary personal courage. Stephen Hawking's death marked the loss of one of the most brilliant and beloved scientists of the modern era, but his ideas, and his example of the triumph of mind over adversity, endure as a lasting legacy.
