Rise of the Rockets

   2019    Technology
New technologies are making rockets cheaper and more powerful than ever before. As companies like SpaceX and Virgin Galactic make space more accessible, and NASA returns to crewed spaceflight, a new era of space exploration may be on the horizon.

Direct From An Asteroid

   2019    Technology    HD
The Hayabusa2 spacecraft has just completed one of the most intricate procedures in space exploration. The first mission to deliver rovers onto an asteroid has now descended to its surface for a sample, before returning back to Earth in 2020.

The Satanic Verses 30 Years On

   2019    Culture
The publication of Salman Rushdie's novel The Satanic Verses in 1988 sparked a culture war in Britain between those in the Muslim community, who considered the book blasphemous and called for the book to be banned, and those defending it as an expression of freedom of speech. Protests, which began in the north of England, soon spread across the UK and to the rest of the Islamic world, culminating in February 1989 with Iran's Ayatollah Khomeini issuing a fatwa - a death sentence on the writer.
Now, 30 years on, broadcaster and journalist Mobeen Azhar embarks on a journey, starting in his native Yorkshire where the protest first began, to examine the lasting effect the book has had on the Muslim community and how the events of 1989 continue to have an impact today.

Climate Change The Facts

   2019    Nature    HD
David Attenborough takes a stark look at the facts surrounding Climate Change in today's world, detailing the dangers we are already having to deal with and future threats, but also the possibilities for potential solutions to this global threat and the radical political, social and cultural changes needed.
Interviews with some of the world’s leading climate scientists explore recent extreme weather conditions such as unprecedented storms and catastrophic wildfires. They also reveal what dangerous levels of climate change could mean for both human populations and the natural world in the future.

Is the Universe a Hologram

   2019    Science    HD
Shocking new evidence has convinced some of the world's greatest physicists that the universe is a hologram. Using cutting-edge technology, they investigate the secrets of black holes and space-time to build the case for this game-changing discovery.
The holographic principle is a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region like a gravitational horizon. First proposed by Gerard 't Hooft, it was given a precise string-theory interpretation by Leonard Susskind.
The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon.

International Space Station

   2019    Technology    HD
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.
