ImagingGeek:

I found a copy of the paper on the author's web-site.

Man, did google.com hide this paper away from the public.

Robin Canup has a few papers listed here:

"Simulations of a late lunar-forming impact" is here:

I have read the paper thoroughly.

As I suspected, the paper you quoted does NOT claim that the proto-Earth-Theia collision released 10^24 Joules.

Also, nowhere in it, is your earlier claim that the proto-Earth-Theia collision released 10^27 Joules.

You made your earlier claim of 10^27 Joules, here:

It appears that ImagingGeek just makes up his "facts" from thin air.
