What happened at the end of infinite crisis?

I just finished reading Infinite Crisis, I liked it a lot but I have a question. what the heck happened?

Pre Crisis supes and the current Supes take superboy prime through a red sun. ok.. why the heck did they all seem quite "normal" about this? red sun should affect superman, not just take away his powers but also damage him in someway.

Anyways, this is the superboy who just owned the green lanter corps, martian manhunter, black adam, superboy etc.

then he kills pre crisis supes and superman just goes out and kicks his ass! how the hell did this happen? whats the explanation, is it because at that point neither of the 3 supes had superpowers?

Yeah, it was a fit 15 year old vs. a fit 30 year old.

Ah ok, thought so, that makes a bit more sense, cos as much as I love superman and he is my favorite character ever, he shouldnt have been able to do that "power wise" if superboy was full powered.

That was the point of flying through Rao and all the kryptonite. Together the Supermen couldnt beat him when they all had powers but when none of them have powers it's just a man vs a boy...

red sun radiation robs superman of his powers while its hitting him, nothing more...
