The centre of our galaxy is home to an invisible monster of unimaginable power – a supermassive black hole named Sagittarius A star, with four million times the mass of the Sun. Recent astronomical breakthroughs have confirmed not only that black holes like Sagittarius A star exist, but that these bizarre invisible objects may be the ultimate galactic protagonists. Stunning CGI takes us back to witness the fiery origins of our galaxy’s black hole 13.6 billion years ago, when the early universe was home to colossal blue stars, and when they ran out of fuel, they collapsed under their own enormous mass, crushing down into an object so small and so dense it punched a hole in the fabric of the universe. Over billions of years, Sagittarius A star feasted on nearby gas, stars, and through cataclysmic mergers with other black holes. A breakthrough discovery by Nasa’s Fermi gamma-ray telescope has shown that our black hole had the power to sculpt the entire galaxy, creating vast bubbles of gas above and below our galaxy and even protecting stars systems as ours. In a mind-bending conclusion, Brian Cox reveals how our modern understanding of black holes is challenging our concepts of reality to the breaking point. In trying to understand the fate of objects that fall into Sagittarius A star, scientists have come to a stunning conclusion: space and time, concepts so foundational to how we experience the world around us, are not as fundamental as we once thought.
The film explores the science of black holes and delves into the incredible techniques used to uncover their secrets. Researchers reveal the fundamental role of black holes in the evolution of our universe and galaxies, with new findings from James Webb Space Telescope (JWST), Laser Interferometer Gravitational-Wave Observatory (LIGO), and analogue experiments. The documentary also features experiments on Earth that mimic black hole physics, offering insights into their behaviors. Although we may never directly observe the inside of a black hole, these experiments allow us to test theoretical physics and gain a deeper understanding of these enigmatic cosmic phenomena.
The film documents the English heavy metal band Black Sabbath's final show of their farewell concert tour, The End Tour. The performance was held at the Genting Arena in Birmingham, England, hometown of the band's founding members: vocalist Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler, and drummer Bill Ward. Osbourne, Iommi, and Butler performed this final concert with session drummer Tommy Clufetos in place of Ward, as well as Adam Wakeman on keyboards and guitar. The concert opens with a performance of the song 'Black Sabbath'. The film goes on to show the band performing 'Fairies Wear Boots', 'Under the Sun/Every Day Comes and Goes', 'Into the Void', 'Snowblind', 'War Pigs', 'Hand of Doom', 'Iron Man', and 'Children of the Grave'; at the end of the setlist, the band performs the song 'Paranoid' as an encore. Interspersed with the final concert are interviews with Osbourne, Iommi, and Butler, in which they talk about their careers and past drug addictions. Additionally, Iommi's 2012 lymphoma diagnosis, which impacted the band's 2012–14 reunion tour and the recording of their 2013 album 13, is discussed. The film also features footage of 'The Angelic Sessions'—the band's final studio recordings, which took place in the days following the final show. Of these recordings, the film shows Osbourne, Iommi, and Butler performing 'The Wizard', 'Wicked World', and 'Changes'.
This episode looks at a group of black survivalists. British Buzzfeed correspondent Bim Adewunmi looks at an unusual group of doomsday preppers who don't fit the normal stereotype for that group. She interviews people of color who train themselves to prepare for disaster.
This illuminating ten-part series tells the story of World War ll through the ten most pivotal turning points in the conflict. Gripping story-telling illustrated with exquisitely restored and colourised archived films and supported by a global cast of stellar historians bring this crucially important era in history to life. In the first chapter, Britain and France declare war when Hitler invades Poland. In May 1940 the Germans attack Holland and Belgium as a decoy. As the Wehrmacht comes through the Ardennes and the Luftwaffe strikes in force, French leaders are caught like rabbits in headlights. The Germans are on a drug called Pervitin, which beats off fatigue, and reach the Atlantic coast. There is a danger that the Germans will encircle the Allies and cut them off from the sea. But Hitler issues his Halt Order and some 340,000 Allies are evacuated.
Rocky Braat went to India as a disillusioned tourist. When he met a group of children with AIDS, he decided to stay. He never could have imagined the obstacles he would face, or the love he would find.
