The universe will die. The sun and other stars like it will throw out heat until they have no more energy to burn. The big bang threw everything outwards at a massive rate. As it gets bigger, so the gaps between matter get bigger and are filled with "dark energy". Instead of gravity pulling everything back down to a "big crunch" the dark energy accelerates the expansion process, pushing everything further apart faster and faster. In the end everything will be a cold, sad, blackness as the stars all go out, or are too far apart for us to see anything - but "us" will be long gone.

A strange subatomic particle produced in an atom-smashing experiment here on earth could, theoretically, tumble to the centre of the planet and start eating the planet from the inside out - death by industrial accident. Or a random quantum fluctuation in distant space could switch off the machinery that makes matter big, and this would send a bubble of destruction moving at the speed of light and shutting down all creation in its path. All of the ideas explored in this series suggest that the future is not rosy - that the universe is going to end and that we will end along with it...or can we escape?

A series exploring how our ideas about the end of the universe have been shaped by religion, belief, and the contemporary state of scientific thinking and observation. The series is presented by Vatican Astronomer, Brother Guy Consolmagno. He is a Jesuit astro-physicist who came to religion via science and his wonder at the universe. At the Vatican Observatory in Castel Gandolfo, Italy, he compares cutting edge cosmology with Chinese, Ancient Greek, Buddhist, Medieval and Victorian ideas about the end of everything.

It will die. Like a ball thrown into the air, no matter how fast the acceleration to begin with, gravity always wins. The universe will reach a critical mass, then start to fall back in on itself. This is the big crunch theory. The power of gravity wins out over the accelerating power throwing everything outwards. Microseconds from the end, black holes begin to merge with each other, little different from the collapsing state of the surrounding universe. The implosion becomes increasingly powerful, crushing all matter and every physical thing out of existence. Space and time end - there is eternal nothingness beyond this point, unless...

Yes the universe will end, but at the crunch the process starts all over again, and could go on forever (cf. Hindu and Buddhist ideas of re-birth). Another possibility is "multiverses" - there are lots of different universes, all in different states of existence, some at moment of big bang, but will never become a universe as we know it, so grow to the size of a grape and shrink back, or expand outwards and never turn into frothy, lumpy matter - just a thin soup with no life in them. Our universe is perfect…not too fast to become a soup and not too slow so it falls back in on itself to destruct - just lumpy enough for galaxies to form and the whole thing hold together - a balancing act between gravity and acceleration, for the time being.

For one night only, Professor Brian Cox goes unplugged in a specially recorded programme from the lecture theatre of the Royal Institution of Great Britain. In his own inimitable style, Brian takes an audience of famous faces, scientists and members of the public on a journey through some of the most challenging concepts in physics.

In the first of a three-part series, Professor Dame Jocelyn Bell Burnell describes how she discovered pulsars, the by-products of supernova explosions which make all life in the universe possible. She describes the moments of despair and jubilation as the discovery unfolded and her excitement as pulsars took the scientific world by storm.

Physicist Professor Andre Geim\'s constant search for new ideas has led to some extraordinary discoveries, from levitating frogs to a tape that sticks to surfaces like a gecko\'s foot. He reveals how his playful approach to his research helped him uncover the properties of graphene, the world\'s thinnest material, and won him a Nobel Prize.

Professor Richard Dawkins reveals how he came to write his explosive first book The Selfish Gene, a work that was to divide the scientific community and make him the most influential evolutionary biologist of his generation. He also explores how this set him on the path to becoming an outspoken spokesman for atheism.
