Why Stephen Hawking believed the next 200 years are crucial for humanity
Stephen Hawking died early Wednesday, March 14 at his home in Cambridge, England.
The dates of Hawking’s birth and death are shared by two other intellectual giants who also dedicated their lives to studying the cosmos. Hawking was born on Jan. 8, 1942—300 years to the day after the death of Galileo, as he liked to point out. He passed away on Albert Einstein’s birthday, March 14.
Hawking’s work, as he put it, dealt with “the big question: Where did the universe come from?” He provided some answers in his 1988 book A Brief History of Time: From the Big Bang to Black Holes, which has sold more than 25 million copies to date.
Hawking will be remembered for numerous scientific papers and important discoveries in cosmology and astrophysics, including his work on the nature of black holes, the origin of the universe, and attempts to unite quantum theory and Einstein’s relativity.

But Hawking’s reach wasn’t limited to academic circles. Despite suffering from amyotrophic lateral sclerosis (ALS), a disease that left him paralyzed in his twenties, the astrophysicist traveled the world, spoke at conferences, and served as a chief representative for science in popular culture, appearing in shows like The Simpsons, Star Trek: The Next Generationand Futurama, not to mention having his life story dramatized in the 2014 film The Theory of Everything.
“Not since Albert Einstein has a scientist so captured the public imagination and endeared himself to tens of millions of people around the world,” Michio Kaku, a professor of theoretical physics at the City University of New York, said in an interview.
Hawking spoke with Big Think years ago about some of the greatest threats facing humanity.
“There have been a number of times in the past when [humanity’s] survival has been a question of touch and go,” he said. “The Cuban missile crisis in 1963 was one of these. The frequency of such occasions is likely to increase in the future.”
The one great hope for humanity, according to Hawking, is to spread into space. But as the population grows and the world becomes more chaotic, it’s crucial that mankind avoids destroying itself before developing the technology to reach into the stars.
Hawking believed that would take about 200 years.

“I’m an optimist. If we can avoid disaster for the next two centuries, our species should be safe, as we spread into space.”
This requires not falling prey to our worst tendencies.
“Our genetic code still carries the selfish and aggressive instincts that were of survival advantage in the past. It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million. Our only chance of long-term survival, is not to remain inward-looking on planet Earth, but to spread out into space. We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.”

In a statement released after his death, Hawking’s children, Lucy, Robert and Tim, said: “He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humor inspired people across the world.”
“He once said, ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him forever.”
Here’s how others have paid tribute to the visionary physicist:
He lived more than half a century past his doctors’ projection for ALS & humanity is the better for it. Great scientist, humanist, public intellectual, & inspiration to billions. Honored to have met him at Caltech. Stephen Hawking 1942-2018. Now he belongs to the ages. RIP pic.twitter.com/yRemQSGcvw

Remembering Stephen Hawking, a renowned physicist and ambassador of science. His theories unlocked a universe of possibilities that we & the world are exploring. May you keep flying like superman in microgravity, as you said to astronauts on @Space_Station in 2014 pic.twitter.com/FeR4fd2zZ5

"One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn't exist ... Without imperfection, neither you nor I would exist."

I recall when we has giving lectures and it was a huge effort for him to speak (before the tracheotomy and the computer voice) he still made the effort to throw jokes in. That says something.

RIP Stephen Hawking. The world just dropped a lot of IQ points. And, he was a fun person. Very sad news.

Stephen Hawking was a brilliant man, but he was also an incredibly funny man. It was a huge privilege to waste some of his time, and I'll never forget the twinkle in his eye here ...https://t.co/xUmm2qIAiN
