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.

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."
