Professor Brian Cox visits Geneva to take a look around Cern's Large Hadron Collider before this vast, 27km long machine is sealed-off and the experiment to create the simulation of a black hole begins. When it's up and running, it will be capable of creating the conditions that existed just a billionth of a second after the Big Bang. Brian joins the scientists who hope that the LHC will change our understanding of the early universe and solve some of its mysteries.

The second part, Nothing, explores science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. Professor Jim Al-Khalili 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.

Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour. Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.

The films begins at the Maine Correctional Center where Jacinta, 26, and her mother Rosemary, 46, are incarcerated together, both recovering from drug addiction. As a child, Jacinta became entangled in her mother's world of drugs and crime and has followed her in and out of the system since she was a teenager. This time, as Jacinta is released from prison, she hopes to maintain her sobriety and reconnect with her own daughter, Caylynn, 10. Despite her desire to rebuild her life for her daughter, Jacinta continually struggles against the forces that first led to her addiction.
With unparalleled access and a gripping vérité approach, director Jessica Earnshaw paints a deeply intimate portrait of mothers and daughters and the effects of trauma over generations.

Dash Snow rejected a life of privilege to make his own way as an artist on the streets of downtown New York City in the late 1990s. Developing from a notorious graffiti tagger into an international art star, he documented his drug- and alcohol-fueled nights with the surrogate family he formed with friends and fellow artists Ryan McGinley and Dan Colen before his death by heroin overdose in 2009.
Drawing from Snow's unforgettable body of work and involving archival footage, Cheryl Dunn's exceptional portrait captures his all-too-brief life of reckless excess and creativity.

When Homo sapiens, which means 'wise ones,' discovered and controlled fire hundreds of thousands of years ago, everything changed. Fire allowed us to cook food and heat dwellings, and it served as a focal point for storytelling and sharing cultural identity among community members. We don't yet have established parameters for what it means to be 'distinctly human,' It would seem the only thing that separates us from other animals, Neil deGrasse Tyson ponders, is our neurotic need to feel 'special'. Against the backdrop of the Halls of Extinction, Tyson insists that there must be a clear distinction between ourselves and animals that justifies our eating them, wearing them and even bringing an end to their species.
From the birth of the devil in ancient Persia to a searing story of saintliness among macaque monkeys, this episode is an exploration of human potential for change. It concludes with the story of how one of history's greatest monsters was transformed into one of its shining lights.
