From the award-winning team that brought you The Secret Life of Chaos comes a unique television event on the physics of gravity, featuring unexpected historical insights, cutting-edge science and exciting new experiments.
With the brilliant Professor Jim Al-Khalili as our host, we visit the LIGO lab in the USA where gravity waves were discovered and uncover the latest theories about our cosmos that have come from studying the most intense sources of gravity imaginable – black holes.
Elsewhere, Jim even uses Albert Einstein’s theories of special and general relativity to work out how the rate at which you age is affected by gravity and the speed at which you move about.

For the last 12 years, Carter Emmart has been coordinating the efforts of scientists, artists and programmers to build a complete 3D visualization of our known universe. He demos this stunning tour and explains how its being shared with facilities around the world.
This video is about Bells Theorem, one of the most fascinating results in 20th century physics. Even though Albert Einstein (together with collaborators in the EPR Paradox paper) wanted to show that quantum mechanics must be incomplete because it was nonlocal (he didnt like «spooky action at a distance»), John Bell managed to prove that any local real hidden variable theory would have to satisfy certain simple statistical properties that quantum mechanical experiments (and the theory that describes them) violate. Since then, GHZ and others have managed to extend the theoretical work, and Alain Aspect performed the first Bell test experiment in the late 1980s.

This video is about a multistable perceptual illusion, similar to the hollow face illusion, whereby maps or aerial or satellite photos look upside down/inside out, ie, concave (valley) parts look convex and convex (mountainous) parts look concave. Just flip the images around and things will make a lot more sense! Its just because our eyes gauge depth based on the location of shadows, and the sun always casts shadows on the bottoms of things.
