00:00tides going in and out that is literally just the moon's pull pulling water on july 9th

00:07the moon was at such an angle um in which relative to earth's equator it was pretty

00:13distant only fractionally but it was obviously enough to affect the amount of water on the side

00:18of the planet therefore the spin of the earth and this culminated in ultimately yeah the the day

00:25being a millisecond shorter which is pretty remarkable in the in the grand scheme of things

00:30um there's always anomalies in any kind of like data set it'll require more like following and

00:34tracking but uh it's certainly yeah the earth's not spinning out of control

00:41now we also asked geophysicist duncan agnew what's behind the shorter date in addition to the moon's

00:47pull he sees some other factors take a look climate change has definitely played a role it's it is

00:54actually slows the earth down as ice melts and spreads out over the ocean and that slows the

01:01earth down and we have no way of predicting it but apparently the core has been slowing down

01:06for the last 50 years and as a result the earth has been speeding up i think it's of interest because

01:13the whole idea that the earth the entire earth is spinning at different rates is kind of amazing for

01:22everyday life i'd say it doesn't really matter at all unless you somehow are a magic human being

01:28who can detect a millisecond of difference you're not going to notice geophysicists astronomers and

01:36even nasa are expecting shorter days so mark your calendars this is going to be for july 22nd

01:41and on august 5th so get ready
