Moon Fall Down? 

The new movie Moonfall imagines what would happen if the moon got knocked off its axis and sent towards earth. So is this actually possible? And could we survive? Let's find out in this Science is Hard: What if the Moon Fell Down to Earth?

Rare Earth

Belize! I went on vacation to an island paradise with some friends, but of course couldn't help but make an episode.

It's another video without Francesco, but luckily this time I had the help of some high school students: Preston Smith and Aldair Rosato. Thanks, guys! I appreciate you joining me on this mini-adventure.

How Long To Fall Through The Earth?

stare up at a bright, full moon, and think to yourself,

seems to be playing right into my biggest fears

where the whole damn moon gets knocked off its orbit

and literally starts falling towards Earth.

Along the way, it causes a grab-bag of damage:

deaths, tidal waves, gravitational shifts, and the like.

Now, I'm not here to spoil the movie for you,

because that would be what scientists call,

that the moon could ever be thrown off its axis

like a bowling ball thrown by a drunk and vengeful God?

Science is Hard: Is real-life Moonfall possible?

To begin with, let's get some basic moon facts straight.

The moon is in an elliptical orbit around the Earth.

It's distance from Earth ranges from 362,600

to 405,400 kilometers at any given point.

this could cause the moon's orbit to stretch out

as the force of the object slows it down.

it's actually because of cold hard science:

of the moon and Earth's respective orbits,

speed, and rotation, plus the gravitational pull

And if the moon gets knocked off its orbit,

the difference between the minimum and maximum distances

between the moon and Earth would increase,

Along the way, it would also increase the difference

and create way bigger and scarier tidal waves.

Good for surfers, bad for the rest of us.

its orbit would get more and more elliptical,

The friction created would slow it down even further,

and the moon would eventually crash into our planet

The Roche Limit holds true for any satellite,

i.e. an object orbiting something like a planet.

where the gravity holding a satellite together

is weaker than the tidal forces trying to pull it apart.

Now, the moon was formed around 4 1/2 billion years ago

When this happened, they melted into each other

which is kinda romantic when you think about it.

And the moon was a piece that spun off from this new mass,

thus furthering this intergalactic fairy tale.

And when a satellite has the same make-up as a primary body,

i.e. when the moon baby is descended from its parent planet,

the Roche Limit is about 2 1/2 times the radius

This means that if the moon's orbit reached 11,470 miles

tidal forces would tear that little rascal apart,

But in this case, not all the pieces of our blasted-up moon

as some pieces will be pulled in by Earth's gravity.

If they then survive the fall through our atmosphere,

they'll absolutely wreck a few major cities in the process.
