- Hi, I'm Josh Clark
and this is Brain Stuff,
and I'm here to answer a
very pressing question.
Have you ever been standing
at the edge of water,
say, like an ocean, and
looked down on the horizon
and said, "I wonder exactly
how far away that horizon is,"
you know, where the sky meets
the sea, that's the horizon.
Well, it turns out because
the Earth is curved
that it depends on where you're standing
and how far above water you're standing.
Let's say that you are in the
water and you're up to, say,
your eyes are about eight inches
above the water's surface.
Well again, remember, the Earth is curved,
and despite the ocean seeming flat,
they actually curve themselves,
which if you've ever really
looked at the horizon,
it kinda goes like this a little
bit, which is pretty cool.
But it also goes like this, right?
So, if your eyes are eight
inches above the water,
right then you're about a mile
away from that horizon point
where the sky meets the
ocean, as far as you can tell.
If you're standing up above
water and you're like I am,
about six feet tall, that means your eyes
are about five-and-a-half
feet above the water's edge,
which means that you're about
three miles away from the horizon.
Isn't that amazing?
Going from eight inches above water,
five-and-a-half feet above water
is the distance between two miles
between you and the horizon.
Mind-blowing, if you ask me.
And if you liked this video,
there's plenty more where it came from.
