This is for everyone to see. This is what I posted on page 9 (not page 8).

He made several errors
1. He claims a neutron star is 1/4 as luminous as the Sun (he writes this on the screen with 0.25Lo) then says that means that a neutron star emits 1/4 the power that the sun does.
But this contradicts the equation
Power = 4pi*r^2*sigma*T^4.
Plugging in r=10^4m and T=600,000k (not 10^6 k) for neutron star in the power equation and
R=6.957x10^8m and T=5778k for Sun in the power equation gives
The power of a neutron star is 0.024 times that (not 1/4 of) of the Sun.2. The ratio of the amount of power that Thor was getting hit with and the total power output of a neutron star should be the same ratio as the cross sectional area of Thor and the total surface area of a neutron star. This ratio is
R=1.4/[4pi(10^4)^2]= 1.11e-9 (assuming Thor is 2m x 0.7m rectangle)
So Thor experienced 0.024 x 1.11e-9 = 2.67e-11 times the power of the Sun.
Thor had it opened for less than 60s (from the timestamp).
So Thor tanked less than 2.67e-11 x 3.828e26 x 60s = 6.14e17 J of heat energy.
Very impressive.
I initially plugged in 600,000k and 10km to show that his result was wrong. I used 600,000k instead of 10^6k because that was the amount from the source I found (from many years old neutron star). His source also gives 600,000k as well.
I initial thought he plugged in the wrong value (10^6k) to get his result.
In other words, I thought his error was a conceptual one, and not a math error. Later I plugged in the value he provided (10^6) and found that this gives 0.186 and still not his result. Therefore I concluded that he made a math error. Either way, he made a math error or a conceptual one.
The second error, which Silent and Nibedicus are not addressing, is that Thor blocked a portion of the total energy that came through. Science guy takes the entire cross sectional area of the opened hatch to calculate how much energy was used to melt the metal. That result is faulty due to Thor blocking a portion of it. It's also faulty for any member here to assume Thor tanked all that energy when a good portion wasn't blocked at all (went to heat the metal).
