Various eminent scientists explain the current knowledge of Black Holes and try to answer the question, do they really exist? 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. The two great theories of Einstein's General Relativity and Quantum Mechanics don't work together to explain Black Holes which is a big problem. Other theoretical constructs such as Gravastars and Planck stars have been postulated but proving their existence is just as difficult as that of Black Holes. So where next?
When a mysterious cigar-shaped object is spotted tumbling through our solar system, experts race to uncover it's true nature. The object, nicknamed Oumuamua, meaning 'a messenger that reaches out from the distant past' in Hawaiian, was discovered by the Pan-STARRS 1 telescope in Hawaii. Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid before finally deeming it the first of its kind: a new class of 'interstellar objects.' A recent paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and travelling at speeds of 196,000 mph, might have an 'artificial origin.' The theory is based on the object's 'excess acceleration,' or its unexpected boost in speed as it travelled through and ultimately out of our solar system.
We are living in a new golden age of exploration. Planet hunters are searching far beyond our solar system and they are actually finding new worlds orbiting other suns. Thousands of these alien worlds have already been found, but this is the story of perhaps the greatest discovery yet, a star 40 light-years away with seven Earth-sized planets: Trappist-1. This new discovery of seven alien Earth-like planets in a faraway solar system is a major milestone in our hunt for extraterrestrial life, and experts investigate the secrets of Trappist -1's mysterious worlds to reveal if we're truly alone in the universe.
Jaw-dropping exploration of our obsessions with high places and how they have come to capture our imagination. Only three centuries ago, climbing a mountain would have been considered close to lunacy. The idea scarcely existed that wild landscapes might hold any sort of attraction. Peaks were places of peril, not beauty. Why, then, are we now drawn to mountains? Filmed by the world's leading high-altitude cinematographers, narrated by William Dafoe and set to a specially curated musical performance by the Australian Chamber Orchestra, Mountain captures the fierce beauty of some of the world's most treacherous landscapes and the awe they inspire.
The film offers an in-depth and intimate portrait of the band's spectacular rise from the backrooms of Camden pubs to selling out stadiums across the planet. At the heart of the story is the band's unshakeable brotherhood which has endured through many highs and lows. Using extensive unseen archive, behind-the-scenes and live footage, 'A Head Full of Dreams' sees the band reflect upon their two decades together. It was filmed during Coldplay's record-breaking A Head Full Of Dreams Tour, which was certified as the third biggest tour of all time, playing to more than 5.5 million fans across the world. The film is directed by Mat Whitecross - director of Supersonic, the acclaimed 2016 Oasis documentary - who met the four friends at college in London, before they'd even formed the band. From the very first rehearsal in a cramped student bedroom, Whitecross has been there to capture the music and the relationships on tape.
Earth's surface is covered in weird and wonderful patterns. The Australian outback is covered in pale spots, the work of wombats; a clearing in the endless green canopy of the Congo rainforest has been created by an incredible elephant gathering; and the twists and turns of the Amazon make a home for rehabilitated manatees. This is our home, as we've never seen it before.
