In two mind-blowing hours, Hawking reveals the wonders of the cosmos to a new generation.
The promise of time travel has long been one of the world's favorite scientific "what-ifs?" Hawking explores all the possibilities, warping the very fabric of time and space as he goes.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way...

Join scientists as they grab light from across the universe to prove quantum entanglement is real. Einstein called it "spooky action at a distance", but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon two subatomic particles that mirror changes in each other instantaneously over any distance is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions.
Albert Einstein and Stephen Hawking were revolutionary thinkers who changed everything we know about our universe, and using the latest discoveries, experts explore the connections between these two great minds.

There is something very strange happens in space – something that should not be possible. It’s as if large parts of the world are being ravaged by a huge and invisible celestial vacuum. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: “We left very upset and nervous,” he says, “because this is not something we planned to find.”
Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.
