Jim Al-Khalili | The Secrets of Quantum Physics and Gravity

Featuring unexpected historical insights, cutting-edge science and exciting new experiments, Jim explores some of the most extraordinary phenomena in our universe.

00:00:00 - Gravity: The Force That Shapes Our Lives

Gravity directly affects all people personally, making a difference to our weight, height, posture and the rate at which we age. With the help of volunteers and scientists, Jim sets out to find out where gravity is weakest and where we weigh the least.

00:44:39 - Einstein's Theories

Using Einstein's elaborate theories, Jim Al-Khalili looks at whether the rate humans age is affected by gravity and the speed at which the Earth moves.

01:29:20 - Einstein's Nightmare

Albert Einstein hated the idea that nature, at its most fundamental level, is governed by chance. Professor Jim Al-Khalili reveals how, in the 1930s, Einstein thought he'd found a fatal flaw in quantum physics because it implies that subatomic particles can communicate faster than light in defiance of the theory of relativity.

02:28:29 - Let There Be Life

Physicist Jim Al-Khalili routinely deals with the strangest subject in all of science - quantum physics, the astonishing and perplexing theory of sub-atomic particles. But now he's turning his attention to the world of nature. Can quantum mechanics explain the greatest mysteries in biology?
