Stephen Hawking's IQ Was 160

Renowned for his contributions to physics and cosmology, Stephen Hawking was a brilliant mind known worldwide. With an estimated IQ of 160, he made major scientific discoveries. He explored black holes and the universe, making key contributions to relativity and quantum physics. His idea that black holes can emit radiation, called "Hawking radiation", was initially ridiculed but is now widely accepted, connecting ideas from relativity, quantum theory, and thermodynamics. Hawking's final theory suggested the universe might be a hologram. He proposed that time could be encoded holographically, a bold idea that challenged traditional notions of the Big Bang and time's origin.

In addition to his scientific achievements, Hawking became a household name through his best-selling book, "A Brief History of Time". The book made complex scientific theories easier to understand, earning him global acclaim.

Hawking also looked to the future and warned about the potential dangers of artificial intelligence (AI). He cautioned that the development of full AI could spell the end of the human race, as AI could redesign itself at an ever-increasing rate, surpassing human intelligence and posing an existential threat as he cautioned in his predictions.

Despite his success, Hawking remained humble about his intelligence, famously stating that "People who boast about their IQ are losers".

Hawking's personal life was marked by resilience. Diagnosed with ALS at the age of 21 and given only a few years to live, he defied these odds and lived a long, full life. He continued his research and inspired millions despite his condition, becoming a celebrated physicist and public intellectual.

5 Times Stephen Hawking Revealed Impressive Brain Power

  • Groundbreaking Black Hole Theory: Stephen Hawking proposed that black holes emit radiation, which was unprecedented in theoretical physics. This phenomenon, now known as Hawking radiation, significantly advanced our understanding of quantum mechanics and black holes.
  • Best-Selling Author: Hawking authored 'A Brief History of Time', an accessible book on cosmology that sold more than 10 million copies worldwide. His book brought complex scientific concepts into the public eye.
  • Lucasian Professor of Mathematics: At age 32, Hawking became one of the youngest scientists to be appointed as Lucasian Professor of Mathematics at the University of Cambridge. This position was once held by Isaac Newton.
  • Synthetic Voice Communication: Hawking was told he only had months to live at age 21. Despite his motor neuron disease and prognosis, Hawking embraced technology to communicate. He used a single cheek muscle to operate a speech-generating device, which became an iconic aspect of his public appearances.
  • Presidential Medal of Freedom: In 2009, Stephen Hawking was awarded the Presidential Medal of Freedom, the United States' highest civilian honor, recognizing his contributions to science and his role as a symbol of triumph over adversity.

How Does Stephen Hawking's IQ Compare to the Rest of the World?

Stephen Hawking's IQ of 160 places him in an elite bracket, reached by just 0.003% of people. This remarkable score surpasses the entry requirements for many high-IQ societies, including Mensa, Intertel, and the Triple Nine Society. It qualifies him for the exclusive Epimetheus Society as well. Obviously he doesn't really need any other proof of his brilliance.
