I don't believe you.

I don't believe that Robin Canup would say anything that stupid.

You just make this stuff up,... don't you?

I read the Canup paper about a year ago and I would have remembered any totally crazy result like your claim of a "collision of 10^24 J," for the proto-Earth-Theia impact.

Why don't you try stating that you meant another paper?

You never know, some sucker might believe you.

ImagingGeek:

It seems that last time we talked about the proto-Earth-Theia impact you insisted that the collision released 10^27 Joules.

Did you make up the 10^27 Joules number as well?
