Most of Our Universe is Missing

Synopsis: We can only account for a tiny percentage of our universe - around 4% - so what is the remaining 96% made of? The current favoured thinking relies on the existence of dark matter: a substance you can’t see, made of particles that so far exist only on paper, shaped and formed by a theoretical force that has never been measured. Yet billions of dollars is being spent in trying to find it. And the stakes are high; whoever finds the elusive dark stuff is virtually guaranteed a Nobel Prize, and could well have paved the way for the biggest prize of all - the elusive ‘theory of everything’. But not everyone agrees. Horizon meets the warring factions, from Princeton Professors to a ‘punk cosmologist’, and gets the story first-hand
