BBC Horizon: Is Everything We Know About The Universe Wrong?
2010 · 60 MIN · IMDB 7.4 · 52 VOTES · DIR. Rob Liddell
Overview
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? .

00:00:02 14 billion years ago there was nothing.
00:02:29 Gripping not just galaxies but whole clusters of galaxies spanning billions of light years of space.
00:04:39 maybe it's not like that.
00:07:30 The power of relating physical phenomena
00:09:32 that's why people really want to sign up to it.
00:11:58 The standard model runs into its first problem when the universe is less than a second old.
00:14:54 The problem is that all explosions produce a chaotic pattern.
00:17:42 This cosmic microwave background
00:20:25 In a way, it's too crude to be the real thing that happened in the early universe.
00:22:52 In a fraction of a section, inflation expands the universe a quadrillion quadrillion times.
00:25:42 When we look at the way things move in the cosmos, we soon reach a very profound conclusion.
00:27:58 Because ordinary matter either emits light or reflects it.
00:30:12 If there was another set of 24 particles, identical to these ones
00:32:37 are passing by here every second, and they're doing absolutely nothing
00:34:49 It's cheating in a sense that
00:37:43 for the last seven billion years or so, there's been an acceleration in that expansion.
00:40:13 We don't know what it is so we might as well say it's this.
00:42:05 But the more expanded the universe becomes, the more dark energy is created to fill the gaps.
00:44:18 Like dark matter, dark energy isn't a solution
00:46:37 and understand the story of creation.
00:48:50 about the cosmic microwave background.
00:51:30 we should be looking outside of our universe very far beyond what is
00:54:02 I've been involved with varying speed of light theory.
00:56:17 A lot of these results are tentative.
