Brian Cox looks at our attempts to answer one of the most profound questions we can ask – are we alone in the universe? With scientists sending space probes to the furthest reaches of our solar system and beyond, the scientific search for alien life has begun. Inspired by a childhood love of science fiction, Brian still hopes to hear from ET. In this film, he explains why this search deserves to be taken seriously, and he explores the chances of it happening.

Brian takes a fresh look at the concept of gravity, revealing it to be far more than just the force that makes things fall to the ground.
In the last three years, we've made profound discoveries about the nature of gravity and the way it behaves, and how this relates to the origin of the universe and strange things like black holes. Our theory of gravity has become the attempt to understand the nature of space and time.

Time i s a concept which is so familiar, and yet recent discoveries have revealed it to be far stranger than we could have possibly imagined. In the final programme in the series, Brian explores the enigma of time - a phenomenon we take for granted but which is one of the biggest mysteries in the universe. He recalls highlights from his TV series that touch upon this conundrum.

The Obsidian Mirror is a mysterious artefact crafted from volcanic rock, and it's said to be a device used to communicate with supernatural beings; experts use cutting-edge tech to discover who made this strange relic and why.
A golden disc can answer the biggest mystery of all: Are we alone in the universe? The Voynich manuscript is one enormous puzzle. What secrets are hidden in this bizarre 600 year old book that nobody can read?

Inside the world-renowned physics laboratory Fermilab, a team of scientists are constructing an audacious experiment to hunt for a mysterious new ‘ghost’ neutrino. If they find it, this could transform our understanding of the nature and fabric of our universe. The problem is, these tiny particles are almost impossible to detect.
Elsewhere, physicists conduct experiments in some of the most extreme environments on the planet: from deep mine shafts in South Dakota to vast ice fields at the South Pole. In these unlikely places supersized neutrino detectors hope to unlock the universe’s deepest secrets. Could neutrinos overturn the most precise theory of particle physics that humans have ever written down? Could they even be a link to a hidden realm of new particles that permeate the cosmos – so called dark matter? Scientists at Fermilab are edging towards the truth.

We as humans often question the creation of the universe. How was the universe created? How does it work? This series uses global experts from organizations like NASA and CERN to help us understand how this works, and uses CGI to demonstrate the phenomena.
Episode 1 starts the new season as we dive deep into the black holes. The galaxy M87 is known for having at the core a super massive black hole. This black hole is the first ever photographed and we will witness the experts trying to find out the secrets of this famous black hole. In the meantime, they have overcome the scorching winds and death ray jets. And of all its hurdles, the event horizon will be the most difficult. This place is known for its uniqueness of time and space, where time stays still while the laws of physics fail.
