Renowned physicist Stephen Hawking has died at the age of 76. Diagnosed with a rare form of motor neuron disease, ALS, when he was just 22 years old, he was told that he would only live for another two years but went on to defy the odds to live a long and incredible life.

Hawking became the scientific world’s most unlikely celebrity. Despite being wheelchair-bound for the majority of his life and only able to speak through a voice synthesizer, he authored some of the most important scientific works in recent history, including A Brief History of Time. 

His intellect was so great that he was compared to Albert Einstein and Sir Isaac Newton, and, as a result, people have taken what Hawking had to say about the world very seriously. Now, following his death, the warning he gave to President Trump has gained even more momentum.

Throughout his life, Hawking issued a number of stark warnings to humanity. He believed that the human race was facing a number of imminent threats which could wipe out life on Earth entirely – such as AI, overpopulation, aliens, and, most recently, Donald Trump.

Even though Hawking found fame through his intellect, he won a special place in people’s hearts thanks to his brilliant sense of humor too. He embraced all aspects of popular culture and even had a cameo in The Simpsons.

Hawking’s incredible life and rise to fame were dramatized in the 2014 movie, The Theory Of Everything.

Although Hawking made a number of impressive discoveries throughout his life, it is believed that he will be best remembered for his groundbreaking work on black holes – the mysterious structures where the normal laws of physics do not apply.

His theory about black holes, known as Hawking Radiation, was never proven in his lifetime, but if it had been, he would have likely been awarded a Nobel Prize. He theorized that black holes can emit energy, despite science claiming nothing can escape their gravity.

Hawking’s warning about President Trump, however, is not only a lot easier to understand but a lot easier to prove.
