what is everything, and what is nothing? Professor Jim Al-Khalili explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness. EVERYTHING: what the universe might actually look like and the remarkable stories of the men and women who discovered the truth about the cosmos. NOTHING: science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim Al-Khalili can prove it.

La matière noire, inconnue indétectable dans nos modèles physiques, peuplerait massivement le cosmos. Pour la première fois, un film montre la folle quête scientifique dont elle est l'objet. Un vrai thriller. Dans nos modèles physiques, le poids de toute la matière observable (étoiles, galaxies…) ne représente que 4 % de l’univers, alors qu'une matière inconnue, invisible, qu'aucun outil n’a jamais permis de détecter, peuplerait massivement le cosmos. Aujourd'hui, astrophysiciens et cosmologistes, chercheurs dans les champs de l'infiniment grand et de l'infiniment petit, unissent leurs forces pour résoudre cette grande énigme : quelle est la nature de cette fameuse « matière noire » ?

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow’ not only has implications for the destinies of large numbers of galaxies – it also means that large numbers of scientists might have to find a new way of understanding the universe. Dark flow is the latest in a long line of phenomena that have threatened to re-write the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong? .

Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing? 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.
