Through the Wormhole episode 2 -The Riddles of Black Holes

Through the Wormhole episode 2 The Riddles of Black Holes - they are the most powerful objects in the universe. Nothing, not even light, can escape the gravitational pull of a black hole. Astronomers now think there are billions of them out in the cosmos, swallowing up planets, even entire stars in violent feeding frenzies. New theoretical research into the twisted reality of black holes suggests that three-dimensional space could be an illusion. That reality actually takes place on a two-dimensional hologram at the edge of the universe. Academy Award-winning actor and space enthusiast Morgan Freeman executive produces hosts and narrates this exploration of the greatest mysteries of the universe. This new series, produced by Freeman's Revelations Entertainment, seeks the answers to the big questions: Are we alone? Where did we come from? Is there life on other planets? From the latest work at NASA and private enterprise facilities to the latest theories from academics and researche

How the Universe Works - Are Black Holes Real ep.1 2018

New discoveries are challenging everything we know about black holes -- astronomers are beginning to question if they even exist. The latest science tries to explain how they work & what they look like, despite the fact we've never actually seen one. [video width="1278" height="720" mp4="https://video-clump.com/wp-content/uploads/2018/02/Are-Black-Holes-Real.mp4"][/video] What Is a Black Hole? A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. How Big Are Black Holes? Black holes can be big or small. Scientists think the smallest black holes are

The Sky at Night - Stephen Hawking on Black Holes

Stephen Hawking on Black Holes: The programme looks at the latest understanding of black holes, featuring an interview with Stephen Hawking. Black holes are one of the greatest mysteries in the universe. They behave in a way that is contrary to laws of physics and one has never actually been seen. However, the recent detection of gravitational waves, as predicted by Einstein, proves that black holes exist and provides a way to investigate their remarkable behaviour and properties. Stephen Hawking made headlines back in January 2016 when he told the world he'd found a possible solution to his black hole information paradox. Or in other words, he'd come up with a potential explanation for how black holes can simultaneously erase information and retain it. Our original understanding of black holes, according to Einstein's generally theory of relativity, is that everything that crosses the event horizon - the boundary of a black hole - is lost forever. Even light can't esca
