Horizon: How Big is the Universe

00:00:02 The most ambitious map in history

00:02:43 and you get a full, almost a full night in.

00:05:44 As we zoom in here to the centre of the galaxy

00:08:39 There may well be a lot more universe outside

00:11:00 If we went to another galaxy, we'd see exactly the same thing.

00:12:46 you wouldn't draw a new map.

00:15:19 "Well, you're going to be busy tomorrow!"

00:17:44 If you were a futurist you'd say

00:20:09 and it's... I have a hard time wrapping my head around

00:22:41 because it's never been detected on Earth.

00:25:17 so we can't look for its silhouette to map out where it is.

00:27:45 stretching eight billion light years from Earth.

00:30:03 Dark Matter puts a very heavy foot on the brakes.

00:32:57 If you want to measure distances across the universe

00:35:18 If you could work with anything else in the world

00:37:38 The points were not showing up where you would expect.

00:39:52 Welcome to a very new picture of the universe.

00:41:46 It's kind of just a uniform colouration to our map.

00:43:31 We go out, we make this map, we discover this land

00:45:55 and stretch to infinity in all directions.

00:48:05 like the light left over from the Big Bang.

00:50:55 if the angles inside the triangle added up to greater

00:53:16 Sometimes when I'm headed down the highway and I'm driving

00:55:35 may sound far-fetched.
