When you think of scientific genius, it’s hard not to picture Stephen Hawking. You probably first heard his name in a classroom, on a documentary, or even through a casual pop culture reference. Whichever way, Hawking’s impact is almost impossible to miss. From his theories about black holes to his unexpected cameos on The Simpsons and The Big Bang Theory, Hawking wasn’t just a world-renowned physicist—he became a symbol of intellectual curiosity, resilience, and humor.
What makes Hawking’s story even more compelling is that his journey wasn’t smooth. He was diagnosed with Amyotrophic Lateral Sclerosis (ALS) in his early 20s and given just a few years to live. Most people would have slowed down after receiving such devastating news, but that wasn’t Hawking’s style. Instead, he defied the odds, living with the disease for more than 50 years. And while ALS took his physical abilities, it never touched his mind. Hawking’s sharp wit, brilliant ideas, and passion for understanding the universe were just as strong decades after his diagnosis as when he first started studying physics.
But beyond the blackboards, equations, and his robotic voice, Hawking was a fascinating person with an extraordinary life. From making significant scientific breakthroughs to betting on black holes, here are 14 captivating facts about Stephen Hawking that show just how remarkable he truly was.
1. He Was Diagnosed with ALS at 21
Stephen Hawking was only 21 when he was diagnosed with ALS, a disease that typically gives its sufferers only a few years to live. Doctors told him he’d have no more than two years. Yet, Hawking lived for more than five decades, continuing to defy medical expectations and redefine what it meant to live with a disability.
Even as his physical condition deteriorated, he found ways to communicate and work. His legacy isn’t just his discoveries but his sheer determination to keep pushing boundaries.
2. His Early Academic Struggles
Believe it or not, Hawking wasn’t a stellar student from the start. In fact, he admitted freely during a public lecture that he didn’t really learn how to read properly until he was 8 years old. While his peers excelled in school, young Hawking was far from a top student. Hawking referred to his attitude as “lazy.”
It wasn’t until his teen years that his true passion for science and math began to emerge. It’s funny how the “lazy” student ended up reshaping our understanding of the universe.
3. His Ph.D. Thesis Crashed Cambridge’s Website
In 2017, Hawking’s 1966 Ph.D. thesis, Properties of Expanding Universes, was made available to the public online. The response? Absolutely overwhelming. So many people wanted to read it that the Cambridge University website crashed due to the sheer volume of traffic.
Hawking’s early thoughts on the universe and cosmology clearly still captivate the world, proving his work continues to inspire curiosity even decades after it was first written.
4. Zero Gravity? No Problem!
In 2007, despite his physical limitations, Hawking got to experience zero gravity aboard a specially modified Boeing 727. For the first time in decades, Hawking was able to float freely, experiencing the same sensation astronauts feel in space. He described it as freeing and exhilarating.
Hawking’s love for space never faded, and this experience only strengthened his belief that humanity should aim for the stars.
5. Hawking Revolutionized Black Hole Theory
If you believe one thing is synonymous with Stephen Hawking, it’s probably black holes. In 1974, Hawking made the groundbreaking discovery that black holes aren’t entirely black. Instead, they emit radiation (now famously called Hawking radiation), and eventually, they can even evaporate. This theory shook up the physics world and changed how we understand these mysterious cosmic giants.
His work on black holes was revolutionary, and it continues to influence research in theoretical physics.
6. He Communicated Using a Single Muscle
As his ALS progressed, Hawking lost almost all control of his body. However, he continued to communicate through a highly sophisticated computer system. Using just a single muscle in his cheek, he could spell out words and sentences, which the computer converted into his famous robotic voice.
This system allowed him to continue writing books, giving lectures, and engaging with the world long after his body had stopped cooperating.
7. His Book ‘A Brief History of Time’ Was an Unlikely Bestseller
Hawking’s A Brief History of Time was never expected to be a bestseller. After all, it’s a book about cosmology, black holes, and the nature of time. But it became an international sensation. The book was published in 1988 and spent 237 weeks on the Sunday Times bestseller list, selling more than 10 million copies worldwide.
Its success was astonishing for a book packed with complex scientific ideas. One of Hawking’s most impressive feats was his ability to make such difficult concepts digestible for the average reader.
8. He Lost a Bet Over Black Holes
Hawking once famously made a bet with fellow physicist Kip Thorne over whether information that enters a black hole is lost forever. Thorne argued that information could be retrieved, while Hawking originally believed it was lost. Years later, as Hawking’s own theories evolved, he admitted defeat and conceded the bet to Thorne.
This willingness to change his stance in light of new evidence is one of the many reasons Hawking was such a respected figure in the scientific community.
9. Pop Culture Star
Stephen Hawking wasn’t just a scientific genius. He was also a pop culture icon. He made cameo appearances on several popular TV shows, including The Simpsons, Star Trek, The Next Generation, and The Big Bang Theory. These cameos went beyond being amusing, though. They helped introduce Hawking’s work to people who might not otherwise have encountered it.
Through these various appearances, he showed that even the most brilliant minds can have a sense of humor and be relatable.
10. He Turned Down a Knighthood
Stephen Hawking was offered a knighthood in the late 1990s, but turned it down. While he never gave a public explanation, it’s believed that he refused the honor due to his frustrations with the British government’s funding for scientific research.
Despite this, Hawking received many other honors throughout his life, including the Presidential Medal of Freedom, one of the highest civilian honors in the United States.
11. A Complex Personal Life
Though known for his intellect, Hawking’s personal life was equally fascinating. He married twice, first to Jane Wilde, with whom he had three children, and later to Elaine Mason, one of his nurses. Both marriages ended in divorce, and Hawking’s relationships were often complex, especially given the pressures of his illness and global fame.
Despite these challenges, Hawking remained a loving father and maintained close ties with his children.
12. He Warned About the Dangers of Artificial Intelligence
Hawking was deeply concerned about the rise of artificial intelligence. He famously warned that AI could surpass human intelligence and potentially pose a threat to humanity if not developed responsibly. His cautionary words have sparked debates about the ethics and future of AI development.
While he acknowledged AI’s potential benefits, Hawking urged researchers to be cautious about how far we take this technology.
13. A Space Advocate
Hawking was passionate about space exploration. He believed that humanity’s future lay in the stars and often advocated for space colonization as a way to ensure the survival of the human race. According to Hawking, Earth is vulnerable to too many risks, from climate change to asteroid impacts, for us to rely on this planet alone.
His enthusiasm for space travel continues to inspire many to look beyond our own world.
14. Time Traveler’s Party
In 2009, Hawking held a party for time travelers, but here’s the twist: He didn’t send out the invitations until after the event had passed. The idea was that if time travel were possible, people from the future would show up. No one came, of course, but Hawking used this playful experiment to engage people’s curiosity about time travel and its possibilities.
His sense of humor and his ability to make complex ideas fun were part of what made him so beloved.
