Black Holes: Heart of Darkness

   2021    Science
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.

Chasing Coral

   2017    Nature
Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called 'coral bleaching' -a sign of mass coral death- has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.
Chasing Coral taps into the collective will and wisdom of an ad man, a self-proclaimed coral nerd, top-notch camera designers, and renowned marine biologists as they invent the first time-lapse camera to record bleaching events as they happen. Unfortunately, the effort is anything but simple, and the team doggedly battles technical malfunctions and the force of nature in pursuit of their golden fleece: documenting the indisputable and tragic transformation below the waves. With its breathtaking photography, nail-biting suspense, and startling emotion, Chasing Coral is a dramatic revelation that won't have audiences sitting idle for long.

Clinton Cash

   2016    History
In 2000, Bill and Hillary Clinton owed millions of dollars in legal debt. Since then, they’ve earned over $130 million. Where did the money come from? Most people assume that the Clintons amassed their wealth through lucrative book deals and high-six figure fees for speaking gigs. Now, Peter Schweizer shows who is really behind those enormous payments. He detailed patterns of official corruption in Washington that led to congressional resignations and new ethics laws. He follows the Clinton money trail, revealing the connection between their personal fortune, their “close personal friends,” the Clinton Foundation, foreign nations, and some of the highest ranks of government.
