Stephen Hawking Says Humans Won't Last Another 1,000 Years On Earth



Celebrated physicist Stephen Hawking recently spoke, via hologram, to a very excited audience in Sydney, Australia.

He reveals that he doesn't believe humans will make it through another millennium on Earth.

Hawking says our long-term survival relies greatly on finding another planet to live on, because Earth is too fragile to support us for much longer.

In its 87th year, acting front runners for the Academy Awards are Redmayne, for his portrayal of the ALS-afflicted Hawking in 'The Theory of Everything,'€ and Julianne Moore, a five-time nominee who is long overdue for a golden statuette, for her depiction of a woman suffering from early onset Alzheimer's in 'Still Alice.' The Oscars are presented on Sunday, Feb. 22, 2015, in Los Angeles. (Photo by Joel Ryan/Invision/AP, File)
LONDON, ENGLAND - FEBRUARY 18: The world's best know scientist Professor Stephen Hawking takes VisitLondon.com's Official Guest of Honour Adaeze Uyanwah on a personal guided tour of his favourite places in the city's famous Science Museum on February 18, 2015 in London, England. On the tour Professor Hawking said he was pleased to lend his synthesised 'voice' to actor Eddie Redmayne for his Oscar-nominated performance in The Theory of Everything but added ' unfortunatley Eddie did not inherit my good looks.'

In this April 5, 2010 file photo, Astrophysicist Stephen Hawking, of England, presents a lecture titled, "Out of a Black Hole" at Texas A&M University in College Station, Texas. Hawking says it is too risky to try to talk to space aliens. Oops. Too late. NASA and others have already beamed several messages into deep space, trying to phone ET. NASA _ which two years ago, broadcast the Beatles song "Across the Universe" across the galaxy _on Wednesday discussed its latest search strategy for life outside of Earth. It is more aimed at looking for simple life like bacteria in our solar system than fretting about potential alien overlords coming here. (AP Photo/Dave Einsel, File)

In this handout photo provided by Zero Gravity Corp., astrophysicist Stephen Hawking floats on a zero-gravity jet, in this April 26, 2007, file photo. The modified jet carrying Hawking, a handful of his physicians and nurses, and dozens of others first flew up to 24,000 feet over the Atlantic Ocean off Florida. Nurses lifted Hawking and carried him to the front of the jet, where they placed him on his back atop a special foam pillow. The plane made a total of eight parabolic dips, including two during which Hawking made two weightless flips like "a gold-medal gymnast," said Peter Diamandis, chairman of Zero Gravity Corp., the company that owns the jet.

Hawking has expressed this belief in the past, and largely attributes the inevitable demise of the planet to the destructive ways of humans. He specifically mentioned war, resource depletion and overpopulation.

In 2010, Hawking warned, "Our only chance of long-term survival is not to remain inward looking on planet Earth but to spread out into space."

However, based on his response to a question from the Sydney crowd, there's another source of hope for mankind – alternate planes of existence.

When asked how he felt about Zayn Malik leaving One Direction, he replied, "It would not be beyond the realms of possibility that somewhere outside of our own universe lies another, different universe. And, in that universe, Zayn is still in One Direction."
