Professor of physics Jim Al-Khalili investigates the most accurate and yet perplexing scientific theory ever - quantum physics.
A documentary that explores how humanity came to understand the universe and its origins in the Big Bang.
Scientists have been fascinated with the idea of controlling gravity for over 200 years. In the mid-1990s, British aerospace manufacturer BAE Systems began a ground-breaking project code-named 'Green glow', which set about turning science fiction into reality. NASA was simultaneously running its own Breakthrough Propulsion Physics Project. Looking at these past projects and into the future, BBC's Horizon explores science's obsession with the idea of gravity control. Are flying cars and journeys to the stars still the stuff of dreams?
Brian Cox explains how we can discover what stars are made of by analysing the light that arrives on earth from the stars. Elements are shown to emit certain colours when they are burnt.
Professor Brian Cox explains how stars die. Stars are only able to survive as long as they have a supply of hydrogen to burn. But all stars will eventually run out and then die.
Professor Brian Cox demonstrates how the chemical elements are made in the death throes of a dying star. All 92 elements on Earth, including those that make up our bodies, were formed at the heart of a star.
Professor Stephen Hawking is going to help you think like a genius, reveal your true potential and answer some big questions about the world around us.
Head into the heart of the universe's biggest storms and discover cataclysmic space weather that could cripple all life on Earth.
'Space Gandalf' Greg Quicke shows us how to find the iconic Zodiac constellations in the night sky. He also reveals how we can use them as guideposts, to mark the path of our planet through space and our everyday lives.
Astronomer Greg Quicke shows us how to identify some of the night sky's unusual sights, from spotting the International Space Station with the naked eye to meteor showers, and how to tell weather balloons from UFOs.
Greg Quicke shares how he discovered the huge influence the moon had on his life as a pearl diver. He shows us how to experience it for ourselves, by connecting the visible phases of the moon to the tides on Earth.
The time has come to explore the last great frontier of our solar system - the sun. On a ground breaking mission, the fastest manmade object ever will fly into its atmosphere in humanity's first attempt to touch our star.
Greg Quicke reveals how seeing the planet Saturn through a telescope for the first time led him to a revelation about the size of our solar system.
Astronomer Greg Quicke reveals how a quirk of our planet's orientation in space plays a fundamental role in creating the seasonal cycle on Earth.
In the south of France, scientists from 37 countries are building the most complex machine ever attempted: an artificial sun. If they get it right, it will illuminate the way to produce clean, cheap, abundant energy for millions of years. If they fail, it will be one of the biggest scientific failures of all time. Nuclear fusion has been the holy grail of energy for many decades now. It’s the process that drives stars, the ultimate source of energy in the universe. The possibility that fusion might be achievable on Earth as an energy source has driven scientists to the edge of reason for almost a century. Original title: Let There Be Light.
Outback astronomer Greg Quicke demonstrates a simple stargazing technique, by which we can accurately follow the orbit of our planet through the night sky as it makes its vast 470 million km journey around the sun.
Greg Quicke shares how he came to realise that the solar system was just as predictable as his beloved Harley Davidson. Using basic stargazing skills, he shows how to locate a key navigation point: the South Celestial Pole.
'Space Gandalf' Greg Quicke shares the stargazing discovery that inspired him to become an astronomer: How to observe the rotation of the Earth in space, by watching a handful of easily observable stars.
Professor Brian Cox is able to witness the oldest light in the Universe, by listening to its stretched wavelengths through a radio.
Professor Brian Cox explains the concept of entropy and the arrow of time. Entropy is the measure of how many ways in which something can be rearranged.
Professor Brian Cox simulates the strength of gravity on other planets using a centrifuge in Holland. Gravity is the force that keeps our feet on the ground.
