Oh, and incidentally, Theia was named after the Greek Titan, believed to 
be the earth goddess of sight and the light of the sky, who gave birth to 
the moon goddess, Selene. So there’s a bit of trivia for you that I 
personally find very fitting. Whether you think it’s clever or not, you 
should be thankful. Certainly, the name Theia is more suggestive and 
memorable than the series of digits and letters that are sometimes used 
to name outer-space objects.

So, anyway, back to what I was describing. And, you know what? Let me 
just get this picture up now, because it’ll make more sense. I was going 
to wait until we started talking about the math involved in the model, but 
you might as well see what I’m describing.

Now, why does the iron core matter? Well, it turns out that without this 
extra massive iron core the Earth would not have the strong magnetic 
field that it does.

And the iron core matters for other reasons…but I’m getting more off 
topic than usual here.
Another piece of evidence is the computer model of the Giant Impact 
itself.
