ImagingGeek, why don't you just admit that your number of 10^27 joules is totally wrong.

Why don't you just admit it like a man and get on with life.

FIRST COMMENT:

YOU ARE OBVIOUSLY WRONG.

As has been pointed out to you before, a release of 10^24 kilojoules = 10^27 joules, for the proto-Earth-Theia collision is obviously wrong.

The amount of energy for each kilogram of Earth is;

= 10^27/(the mass of Earth)

= 10^27/(5.97369 x 10^24) = 167.4 joules.

So, how much will 167.4 joules of energy heat each kilogram?

Well, 1000 joules will heat one kilogram one degree centigrade (i.e., the specific heat for the Earth is 1000 Joules/kg°K)

So each kilogram is heated by the collision by 167.4/1000 = 0.1674 degrees.

So, ImagingGeek claims that the proto-Earth-Theia collision will raise the temperature of the entire Earth by ONLY 0.1674 of a degree. Which is obviously wrong.

ImagingGeek claims that a 0.1674 degree rise in temperature for the proto-Earth-Theia collision, is, in fact, correct.

Excuse me everyone, but surely this proves beyond a shadow of a doubt that ImagingGeek is stupid.
