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?
Ninety million miles away from us is the power that shapes our world - the sun. We see it shine in the sky above us, but beyond our sight something dramatic is happening - the sun is going into overdrive. It's more active now than it's been for a decade, sending eruptions of super-heated plasma and vast waves of radiation towards our planet, with the potential to disrupt our lives in dramatic ways. Using the latest satellite images, and the expertise of Britain's leading solar scientists, Kate Humble and Helen Czerski reveal the inner workings of our very own star, and the influence its mysterious cycles of activity have on our planet.
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.
The forces of nature have kept Earth on the move since it was formed billions of years ago, we follow its epic journey shaping our lives.
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.
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.
Professor Brian Cox experiences what a world without gravity would be like. Brian falls from 15km on board a special aircraft, nicknamed the 'vomit comet', to experience weightlessness.
Brian Cox explains why black holes are invisible. Black holes are the most destructive forces in the universe, able to devour whole stars. We cannot see them, but we can see the effect they have on the surrounding space.
Dr Joel Gilmore demonstrates how to make a caramelised carrot soup in a pressure cooker, a recipe developed by scientist Nathan Myhrvold, and Dr Andrew Stephenson explains how pressure cookers work. When liquids are heated, the molecules take on enough energy to separate into a gas. However, when the molecules can't escape, as occurs in a pressure cooker, they remain trapped inside the liquids, raising the thermal energy and therefore the boiling point.
Ben Milbourne uses conduction and convection to whip up an amatriciana pizza, and Dr Andrew Stephenson explains how these two processes work. Conduction is the transferral of heat through a medium, such as a pan, while convection describes the way fluids, such as oil or steam, create different temperature pockets and cause heat to rise and fall along convection currents.
From award winning producer David Grubin this biography presents a complex and revealing portrait of one of the most important American scientists of the twentieth century. Interweaving interviews with family members, scholars and colleagues with dramatic recreations featuring Academy Award nominated actor David Strathairn, Good Night, and Good Luck, and The Bourne Ultimatum, this program follows J. Robert Oppenheimer on a fascinating arc through the century, from the heady world of international physics to the top secret Manhattan Project, and finally to the dark days of the Red Scare and McCarthyism.
How do we hear music coming from a speaker? Join Yanick as he investigates how vibrations are made in a speaker and how sounds travels through different mediums to bring the sweet sounds of music to our ears.
Join Yanick in the Physics House to take a look at the physics behind everyday phenomena we encounter in our homes.
