Have you ever wondered how the legendary Stephen Hawking thinks about the universe? He has worked on some of the most mind-boggling physics and cosmology questions, like what’s at the center of a black hole. This video from The Guardian’s Made Simpleseries, animated by Scriberia, explains some of the main ideas of Hawking’s complex theories from his book A Brief History of Time, in just 150 seconds.

Here are some of the highlights from the video.

What actually is at the center of a black hole? A singularity – or tons of matter packed into a tiny space. That high concentration of matter basically creates infinite gravity – that’s why nothing can escape a black hole.

What happens when a black hole disappears? It explodes, and the explosion has a force equivalent to a million nuclear bombs.

Why is Stephen Hawking so well-known? His work suggests that at one point, everything in our universe was squeezed into one of those singularities. Then, it exploded into the universe as we know it now.

Stephen Hawking: Humanity Won’t Survive Another 1000 Years on Earth

 Theoretical physicist Stephen Hawking says that humanity won’t make it through the next 1,000 years unless we find a way to leave Earth.

 “We must continue to go into space for the future of humanity,” Mr. Hawking told an audience at the Sydney Opera House, where he appeared virtually, in holographic form. “I don’t think we will survive another 1,000 years without escaping beyond our fragile planet.”

Hawking was filmed in his office at the University of Cambridge, in the UK, and the footage was sent via San Jose for processing then on to Australia to create his image on stage.

“He’s worried about the future of the human race. You know, he thinks that human beings are, I suppose naturally aggressive,” said Professor John Webb, the director of the lecture series at the University of New South Wales that made Hawkings talk possible.

“That may have been useful at some point in the early history of humanity enabling us to find food and get a partner and things like that, but he thinks that aggression that remains with us today is now the thing that could well end up destroying us.”

“I think he’s put a time on it to make us realise we’ve got to take better control of what we’re doing.”
