:23:02
It's made up of...
electricity and magnetism,
:23:05
so it's called...
creatively enough...
:23:06
the electromagnetic field.
:23:08
It's where we get our magnetic
North Pole and South Pole,
:23:11
and it protects us
from cosmic radiation.
:23:13
So this EM field is our friend.
:23:15
But now...?
:23:17
But now,
:23:18
that field is falling apart.
:23:20
Why?
:23:21
Why?
:23:24
This here.
:23:28
Does somebody have a can
of air freshener?
:23:34
Quick and dirty.
:23:37
The thin skin,
that's the Earth's crust.
:23:39
That's what we live on.
:23:41
It's 30 miles thick.
:23:42
The meat here,
call it the mantle.
:23:46
And forgetting
all the-the funky transitions,
:23:49
it's 2,000 miles thick.
:23:50
The core,
:23:53
the peach pit in the center...
that's a tricky one.
:23:55
There's two parts...
:23:56
the inner core
and the outer core.
:23:58
Are you following me?
:23:59
The inner core
:24:00
is, uh...
:24:02
well, it's a big, solid chunk
of iron,
:24:04
we think.
:24:05
And that's surrounded
:24:06
by the outer core,
and that is liquid.
:24:08
Yes, but,
:24:10
most importantly, this liquid
is constantly spinning
:24:12
in one direction.
:24:14
So a trillion trillion tons
of hot metal
:24:17
spinning at
a thousand miles an hour, so...
:24:20
Right, so Physics 101...
:24:21
hot metal moving fast
makes an electromagnetic field.
:24:24
This spinning liquid outer core
is the engine
:24:26
that drives the EM Field.
:24:28
And that's where
we have our problem.
:24:31
This engine has stalled.
:24:33
The core of the Earth
has stopped spinning.
:24:38
How could this have happened?
:24:42
We don't know.
:24:46
What's the timeline here?
:24:47
As the EM Field
becomes more and more unstable,
:24:50
we'll start seeing
isolated incidents.
:24:52
One plane
will fall from the sky,
:24:53
and then two, and then...
:24:55
in a few months, anything...
:24:56
everything electronic
will be fried.
:24:58
Static discharges
in the atmosphere
:24:59
will create "super-storms"
with hundreds
