British physicist Stephen Hawking died on this day, March 14, in the year 2018. His death at the age of 76 sent his admirers, as well as people in the scientific community, into deep shock.
Hawking, who has battled amyotrophic lateral sclerosis (ALS) for more than five decades, was told he had less than three years to live when he was first diagnosed. However, he didn’t let the disease stop him from becoming an icon in the scientific community.
The physicist connected quantum mechanics (which focuses on how electrons and positrons work) with relativity, according to The Verge. This remains one of his greatest successes.
Hawking’s book A Brief History of Time was an international bestseller and continues to be influential since it was first published in the 1980s. The book was much loved by readers for simplifying complex theories regarding the origin of the universe, black holes, and other topics.
Aside from huge contributions to physics, Hawking was also a pop culture icon, appearing in several shows including The Big Bang Theory and The Simpsons.
Stephen Hawking’s contribution to the scientific community will always remain valuable. On the anniversary of his death, here are some of his groundbreaking theories:
In the 1960s, Hawking, along with Roger Penrose, applied Albert Einstein’s theory of relativity to the origin of the cosmos. The theory held that space and time started with the Big Bang and would end with black holes. According to Hawking, questions about what came before the Big Bang were useless if the universe started from a singularity or just one infinitesimal point. He also gave more solid mathematical support to the idea of black holes, first theorized by Albert Einstein in 1916. Hawking also showed that black holes actually emit radiation. The phenomenon was later named the Hawking radiation in his honor. The physicist also discovered that black holes can explode and die. His ideas also led to the discovery that black holes were not actually black, but “white-hot”. Hawking theorized that black hole event horizons, “the limit beyond which nothing can ever escape,” could never shrink. This was later called Hawking’s area position. In 2021, physicists at the Massachusetts Institute of Technology confirmed the theory.
Hawking also suggested that when a star dies, its mass collapses into a singularity, which then leads to the formation of a black hole.
His work has made black holes more comprehensible to both the scientific community and the general public.
