Re: A Violent Splash of Magma That May Have Made the Moon
#2A question I’ve been wondering about: To what extent is the contemporary Earth’s crustal composition a mix of Theia and the proto-Earth? If Theia was roughly one tenth of Earth by volume, where did all that matter end up?

#4I wonder how much bigger the Earth would have been if it hadn't been smashed by a planetesimal? (Assuming the theory is true).

Without tides we may not even exist in that scenario.

Also, if you play the animation slowly, you can see a brighter circle forming at the point of impact, before the impact. Is that part of the simulation or an artifact of the animation, I wonder?

From the article:
> During Earth’s earliest days, it was covered by a sheet of molten silicate rock. Dr. Hosono’s team wondered what would have happened if Theia had crashed into Earth at that time, rather than during a later, cooler, more solid phase.
This is the simulation of how a moon could have been formed, this is not supposed to represent the formation of the actual Moon.

I'm guessing it's the low energy light from the rendered sphere.

#9They should also account for the possibility that the moon rocks are actually from earth. Just in case the moon landing was faked

My interpretation is that the surface magma, cooled down hence the dull orange, is blown away by the bow shock in the atmosphere from the other body entering the atmosphere. This exposes the hotter, brighter, underlying magma.
Could of course be entirely wrong.
