Bitcoin, the beautiful anonymity of cash, but cash that wasn't printed by governments. Instead, it was made by a bit of code, powered by citizens of the internet, and you could trust it. Today, anyone can buy cryptocurrency. A few signups, type in your credit card number, and trade in your money for digital cash. And with a few more steps, you can use Bitcoin to buy what the majority of Bitcoin is spent on: Illegal services. Virtual currencies can pose challenges for law enforcement, given the appeal they have among those seeking to conceal. Is digital cash the next revolution? Learn about this anonymous currency and why it's so coveted.
After years of anticipation, autonomous vehicles are now being tested on public roads around the world. As ambitious innovators race to develop what they see as the next high-tech pot of gold, some experts warn there are still daunting challenges ahead, including how to train artificial intelligence to be better than humans at making life-and-death decisions. How do self-driving cars work? How close are we to large-scale deployment of them? And will we ever be able to trust AI with our lives?
Gaby Roslin and Amir Khan present a program in which they apply the latest science to some of the worst sleepers. They include an extreme snorer, a man who suffers from night terrors, a woman who has restless leg syndrome, and a man with chronic insomnia for 20 years. The film also shows a sleep deprivation experiment to test for risky behaviour, pain resistance and emotional control. When the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether.
The International Space Station is the ultimate extreme home. Costing $150 billion, it is the most expensive structure humans have ever built, in the most inhospitable environment known to man, with no air food or water. Assembled at 250 miles above the earth, it's an epic engineering challenge. We're going to take it apart and uncover what's going on inside the ISS. Its superstructure secrets will help our species reach other planets and beyond. Using photo-real computer graphics, we take it apart to uncover the extraordinary innovations that enable it to support life in the deadly vacuum of space.
The most innovative area of human motion lies not on Earth, but with the exploration of space. Space is the most hostile environment we know. Navigating it involves crossing unprecedented distances. It's the greatest engineering challenge humanity has ever undertaken. Meet the pioneers who've dreamed of reaching other worlds, pushing the boundaries of space exploration, and the private space entrepreneurs jostling to offer the tantalizing prospect of cheap, frequent travel beyond the atmosphere into Earth orbit.
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?
