Stephen Hawking: Humans have only about 1,000 years left
Stephen Hawking thinks our days are numbered – unless we find new planet to live on.
During a talk at the Oxford Union debating society this week he said humanity probably had only about – 1,000 years left before going extinct.
Hawking, 74, has spoken several times of what he sees as our doomed fate, with risk of things like nuclear war increasing as well as – threat of global climate change also he warned that developing of artificial intelligence could end mankind.
Our only hope to escape these dangers, Hawking says is to find another planet to live .
“We must also continue to go into space for future of humanity,” he said. “I don’t think we will survive another 1,000 years without escaping beyond our fragile planet.”
NASA launched its Kepler spacecraft in 2009 with mission to do just that. It was designed to search nearby region of our galaxy for Earth-size planets orbiting in habitable zone of stars similar to our sun. zone called the “Goldilocks zone” because it is — range in which pressure and temperature – “just right” for liquid water to exist on a planet’s surface.
