Jim Al-Khalili shows how investigation into the atom unravelled the mystery of creation.
How studying the atom forced us to rethink the nature of reality itself.
Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible!
