Gravity and Me: The Force that Shapes Our Lives
BBC documentary hosted by Jim Al-Khalili. Gravity is a fundamental force of nature, shaping our entire universe. The force pulls all things in the universe toward one another, including planets, stars and galaxies, and other physical objects. Gravity also directly affects all of us very personally - making a difference to our weight, height, posture and even the rate at which we age.
Physics professor Jim Al-Khalili tells the story of gravity, recreating Galileo's Leaning Tower of Pisa experiment, looking back at Newton's law of universal gravitation, and investigating Einstein's view of gravity as a geometric property of space and time. He also finds out from astronauts what it's like to live without gravity.
Visiting LIGO Livingston Observatory, Jim Al-Khalili investigates the latest breakthrough - 'gravity waves' - ripples in the vast emptiness of space. And He discovers that despite incredible progress, gravity has many secrets.
