00:15So, dogmat
00:20is this
00:21invisible
00:21architect
00:22of the universe
00:23and
00:25even if it's invisible
00:26we can observe it indirectly
00:28through the effect it has
00:30on the stars in the background
00:32and in particular
00:33its gravity
00:35and that gravity
00:37will subtly
00:38bend
00:39the light from
00:40very distant galaxies

00:50As the light
00:53travels towards us
00:54from those
00:54dim
00:55distant galaxies
00:56at the other side
00:57of the universe
00:58it has to navigate its way
00:59through all the dark matter
01:00and light
01:00it turns out
01:01doesn't travel in straight lines
01:02it gets slightly bent
01:03all the time
01:04and what happens
01:04is
01:05is that
01:05those distant galaxies
01:06appear
01:07slightly
01:08distorted
01:08they appear
01:09war
01:10warped into unusual shapes
01:11and by looking at
01:12across the galaxies
01:13we sort of see
01:14oh there's one
01:15that looks like the milky way
01:15there's a fuzzy blob
01:16oh hang on
01:17there's a really unusual
01:18looking galaxy
01:18that's because
01:20it's got some dark matter
01:21in front of it
01:21so that's how
01:22James Webb's based house
01:24comes
01:25can see dark matter
01:25even though it's invisible
