Available on iPlayer for a limited time:
Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing?
In two epic, surreal and mind-expanding films, Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.
The second part, Nothing, explores science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. Jim sets out to answer one very simple question - what is nothing? His journey ends with perhaps the most profound insight about reality that humanity has ever made. Everything came from nothing. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim can prove it.
For those beyond the reach of iPlayer, both programmes are available on YouTube (but expect them to be pulled soon):

In the words of Sir Arthur Eddington, "Not only is the universe stranger than we imagine, it is stranger than we can imagine."
