Are Black Holes Real

   2018    Science    HD
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?

Virgilio Martinez

   2017    Art
Virgilio Martínez is the chef/owner of Central, a restaurant in Lima, Peru that currently sits at number four on the World’s 50 Best Restaurants list. After a decade spent cooking in kitchens around the world, Martínez only found his true identity as a chef when he began exploring the different regions of his native Peru, from the ocean to the Andes. While some chefs are obsessed with a 'sense of place,' Martínez strives to offer his guests a sense of many places — entire ecosystems over the course of a tasting menu.
Martínez always had an adventurous spirit, but growing up in Peru during the 70s and ‘80s meant that many parts of the country were closed off to him. As a teenager, he learned that pursuing a career in the kitchen would allow him the freedom to travel all over the world. The chef ended in charge of a restaurant in Madrid. This is really where Virgilio started to develop his experimental style. Martínez decided to leave Spain to go and work on opening his own restaurant in Peru. He decided to explore the idea of cooking dishes based on altitudes and ecosystems. Martínez runs Central’s kitchen with his wife, Pia León. They developed the altitude-based menu concept together. Martínez’s sister, Malena, has a science background, so he brought her on as part of the team to explore different terrains in search of ingredients that they could use at the restaurant. Virgilio remarks: 'We use 180 ingredients, and 50 percent of them are unknown.' The altitude-themed tasting menu was introduced in 2012, and the following year, Central landed at the bottom of the World’s 50 Best Restaurants list. Two years later, it soared to number four.

The Invisible Universe

   2018    Science
It is one of the most unnerving discoveries in space science - that most of the universe is missing. We live in a material world, so instinctively we know what normal matter is - the world around us, the planets, stars and interstellar dust. But scientists currently estimate that 95 per cent of everything in the universe is actually - one way or another - invisible.
Some of this is ordinary matter that we just can't easily see. But there's also stuff that's much more weird. For instance, there's a new kind of matter we think is out there, but whose very existence is still largely hypothetical - dark matter. And most mysteriously of all, scientists think there is an unknown form of energy pervading the universe that we know so little about, all it has so far is a name - dark energy. Embark on a tour of this invisible universe, and shows how its existence - or lack of it - will define the fate of the entire universe.

Can We Build a Brain

   2018    Technology    HD
Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches... the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence?
The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. The documentary looks at how far we’ve come and where machines are headed as their software becomes ever more... cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?
