I think I'm wasting my time. You clearly have no idea what either of the two of us are talking about.
I do, but I am informing you that your complaint about the math that they used... absolutely doesn't matter because no matter what calculations you use for that feat and no matter how slow you make it... it puts Superman out of Goku's range.
Just being able to push against the gravitational accelleration the sun puts on the earth. As well as the earth's natural ability to rotate itself... is immense.
Remember Goku, with the exagerated measurements they created for him, was only able to lift a continent effectively (And the Goku in the anime couldn't do that even then, the exact multiplication to his abilities wasn't exactly the measures they give. Hense why Goku never crossed the light barrier).
That Cartoon they shown with the alien and the piston is the confirmation but I don't know why you didn't notice that.
Superman routinely demonstrates inertialess contact telekinesis in a variety of his media
That was an explanation that came later. Earlier it was called his Aura of Invulnerbility where he was able to extend his own invulnerbility to objects he was in contact with, which is a better way of understanding it.
He has a limitation however. Hense why he has often had to slow objects down instead of simply lifting them wholesale. Moving the entire earth while cool, is far outside Superman's ability to make it ignore its own structural integrity.
In fact the fact that he NEEDS a harness proves your statement about "Him negating the intertia of the earth" false as otherwise he could have done it by hand.
As for his punching strength
The Infinite mass punch is the key to that. Do you confirm Lord Bucket that he can INDEED pull off the Infinite Mass punch? and that he can move at 6 times the speed of light?
Because it is around now that Ill start to do the math and show you that Superman can indeed punch that hard.
Afterall SURE you say that is only his lifting strength. I will without even touching how much he can lift, prove he can punch that hard.
Though before then this is the specific explanation for the Infinite mass punch
"Infinite mass punch - Introduced in Grant Morrison's JLA title. Flash (Wally West), traveling near the speed of light acquired the relativistic mass of such speed to impart blows which could hit with the force of "a white dwarf star,""By the by Superman cannot fake this.
(I keep doing the math but I get the math wrong everytime)
