Physics, light, gravity, space, time and dark matter
In this second of two interviews, John explains how light is "bent" by the effect of gravity. But what exaclty is gravity? and is it similar to electromagnetism? He then goes on to explain how matter is affected by gravity. John also explains time and illustrates that time is not quite like many people think it is.
Is the Hadron Collider safe? and what on Earth is this stuff calling itself "Dark Matter".
