Just stuff.

Not sure if we are supposed to do a blog post today or not, so I'm just gonna talk about a lot of things.

multimedia swag ;)

First off, Camp Nanowrimo.  Lets just say I'm wayyyyyyy behind. No word count api for this, so you guys cant see just how far behind I am.  And I don't see myself catching up anytime soon, thanks too a variety of time consuming projects coming due. Which brings me to my next point.

Feature story.  Nothing better than stressful stuff, I can tell you that.  I've got my interviews done, but 8 pages is freaking me out, seeing as we haven't talked about feature stories in like a month.  Freaking out about this is a severe understatement.

Cap Court. Togas.  It's gonna be fun.

Wichita St v. Louisville That game.  I just can't.  I wanted Wichita to win so bad. They were up by 11 and then they just lost.  I can't even tell you how nerve racking that game was for me.  Also can we talk about how their mascot appears to be a bale of wheat?

Hi saturn!

Space I feel like I should mention something about space, but like my other interests, my life has been hijacked by school.  So space. It exists.  Please enjoy NASA's astronomy picture of the day, Saturn photobombing a picture of the moon.

How Our Moon Came to Be

^ And who says science isn't cool ^

When our lovely solar system was just beginning to form, the Sun was sorrounded by a bunch of asteroids, dust, and protoplanets.  Protoplanets are baby planets, who develop some sort of core after creation and usually collide with eachother to form the wonderful planets we know today.  Unless its a gas giant which is just a whole bunch of weird that I am not going to get into today.
So when our Earth was young, but was just about fully formed after swallowing a healthy diet of protoplanets, a new protoplanet about the size of Mars named Theia essentially barreled into it.  Theia, like Earth, had a molten iron core. When they collided, most of the planets became molten, and Theia's core became part of Earth's core.  A large chuck of Earth and Theia's mantles were ejected out into space, where they eventually formed an orbit of debris around the Earth. These chunks of debris eventually collided together to form the lovely Moon we know today.

Now of course the moon did not just hit earth head on, because well, when a planet the size of Mars hits a planet of a simular size, neither survive after the explosion of molten chaos.   The moon hit the Earth at an angle around 45°, not too much so that Earth was destroyed, but just enough so that we do not have a lopsided planet named Theia orbiting around the sun still.

The one problem with this theory is that a collison of this magnitude would have to have caused Earth to essentially liquify, meaning that the entire crust was a post apocalypitic sea of magma.   However, scientists have yet to find evidence of a sea of magma like this existing. 

Fun Fact: Theia is named after a Greek Titan who gave birth to the Moon goddess, Selene.  Which is awesome because the protoplanet did become the Moon.  lol astronomers, you so clever.

Here's the Moon, looking all smug. It knows it could have destroyed Earth...I don't trust it. -.-
