"Space, itself, is falling inside the black hole. It's rather like a river falling over a waterfall. It's like that, except it's space, itself, that's falling over the cliff. There's a place where the space starts moving faster than light, so, the light is just trying to get out. It's rather like a kayaker, trying to make their way upstream, on a river that's going too fast. They get dragged down
Like the plot of a sci-fi B movie, something weird is happening deep underground where the constant spin of Earth's liquid metallic core generates an invisible magnetic force field that shields our planet from harmful radiation in space. Gradually, the field is growing weaker. Could we be heading for a demagnetized doomsday that will leave us defenseless against the lethal effects of solar wind an
In June 2000, astronomers made an extraordinary discovery. One that promises to solve one of the biggest problems in cosmology - how and why galaxies are created. Incredibly, the answer involves the most weird, destructive and terrifying objects in the Universe - supermassive black holes. Scientists are beginning to believe that these forces of pure destruction actually help trigger the birth of g
After 40 years, man is preparing to return to the Moon. But this time the astronauts won't just land on the Moon - they plan to stay.From his office in Nevada, Dennis Hope has spawned a multi-million dollar business selling lunar real estate. But scientists believe the real prize is trapped in the Moon's rocks. It contains large deposits of an extremely rare gas called Helium-3. Could Helium-3
This documentary was aired on September 7th of 2008 to coincide with the switching-on of the LHC, the world's largest particle accelerator complex, Professor Jim Al Khalili delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang.The remarkable idea that our universe simply began from nothing has
What would life on earth be like without the moon? Well, chances are, there wouldn't be any life on earth without the moon. Life – if it had started at all – would still be in the earliest stages of evolution.Scientists use the latest computer simulations to show how an ancient rogue planet – Orpheus – collided with the earth millions of years ago, producing a sizable chunk of debris that even
A fascinating documentary by the BBC looking at the human race's relationship with the Moon, starting with elaborate rock formations to map its movements - through to the Apollo missions which explored it.The documentary also looks at other planet's moons, such as Jupiter's Titan and ice covered Europa, which is the best bet for life out side of Earth in the Solor System. It ends with the futu
We cannot compare anything on earth to the largest things known in space. The Lymann Alpha blob is a bubble-like structure containing countless galaxies, perhaps the biggest object in the entire universe.In this documentary we discover which is the largest planet, star, star cluster, constellation, black hole, void, volcano, galaxy, explosion, moon, storm and impact crater in space.
With its famous rings, Saturn is the most distant planet clearly visible to the naked eye. But how did the rings get there and when were they formed? To study the planet in detail, scientists needed to get closer. So on 15 October 1997, the Cassini-Huygens spacecraft was launched.The Cassini-Huygens is one of the most ambitious spacecraft ever launched, taking seven years to reach Saturn. The mi
