Thanks!
Let’s assume the asteroid was moving at 25000m/s (the average speed of asteroids).
ENERGY
The energy to stop the shadow moon
E1 =1/2 MV^2 = 1/2 (7.35e22kg)(7.614e9m/s)^2 =2.1e42 J
The energy to stop the Asteroid
E2 = 1/2 (3 x 5.972e24kg) (25000m/s)^2 = 5.6e33 J
Therefore E1 is 380 million times greater than E2
FORCE
Let’s assume that both characters stopped the objects at the same time after impact.
The force to stop the shadow moon
F1 = M V/t = 7.35e22kg x 7.614e9m/s /t =5.6e32 /t
F2 = 3 x5.972e24kg x 25000m/s /t = 4.5e29 /t
Therefore F1 is more than 1200 times greater than F2.
Note: This assumes that the jet boots supplied no power and that all the pieces were completely stopped and not diverted.

This wasn't just "shadow" which would dissipate in the sun. Otherwise it wouldn't even exist. It was solid mass which was evaporated in the collision.
What's your point? That a small part of the shadow moon survived the collision? Or the entire moon did?
This makes alot of sense. The shadow moon wasn't alive, there was no conscience that was preventing it from fading away before superman destroyed it. So it should have just faded away on its own.
Since that didn't happen it had to be the force of the impact.

Yep. Seem desperate at this point.
The feat doesn’t need disintegration to prove more impressive.

Originally posted by One Big MobWhich autist are you referring to? And yeah, his calc for the shadow moon seems really inflated compared to what I've seen.
Why does h1 have wildly different numbers than that super autist in the link?
Let me do the quick math myself.
1/2 x (7.342×10^22) x 2115000^2
So first you multiply the velocity by itself. I can already tell h1's calc is wrong because he seems to be have just multiplied the listed kilometers per hour by 1,000 to get the meters per hour, when the velocity in calculating kinetic energy should be in meters per second. He'd have to divide it by sixty twice afterwards.
1/2 x (7.342×10^22) x 4473225000000
Next halve the mass.
3.671e+22 x 4473225000000
Multiply the halved mass and squared meters per second velocity together:
1.6421208975e+35 = KE
So still well beyond what is required to destroy the planet Earth, which is 2.487 x 1032 J.
h1's numbers are indeed far too high, because he was using meters per hour, rather than per second.

Pixel scaling is standard for calcs across the net.
Not only that, but there's no point of reference for where the Earth went or where it needed to go in that inconsistent art where a flash of light from the heroes was country sized even though they weren't glowing. What exactly were they scaling off of?
I also found Endless Mike's Mageddon calculations too... it's a doozy. Holy shit is it ever.
It just seems too much for comics.
