How does Mjolnir flying through Atum prove that Thor was on a different plane of existence?
It was Atum that existed on a different plane. That's the reason why Mjolnir went through him and Thor had to adjust his method of attack:

Thor can survive in the hear of Stars:
Even a weakened Bill has survived in a Star that was about to go Nova. If it's feats of heat resistance that is needed, Thor has plenty that I can post.
Well above even the core of the Sun? Really?
Why would Atum be protecting Thor? That makes no sense.
What are you talking about? Thor flew right at the epicenter and was maybe a few feet away from the core. And no he was not knocked out. He was knocked off his feet but that's it.

To be fair though, the Kang Nuclear Weapon was aimed more at organic tissue or what have you.
Why? I think Thor can shrug off a Nuclear Weapon unharmed if the writer needs him to. Thor has feats that make withstanding a Nuclear Weapon seem pitiful in comparison. I didn't want to list them but I can if I have to.
There's also the off panel feat where he survives a Cobalt Bomb. I don't have the scan, but it happens in Journey Into Mystery #86.
i agree with zop that they weren't really in the sun. too weird. they certainly wouldn't just be standing there talking.... anyway, i've debated it at length a couple times in the past and have no desire to do so again since i already know you'll never change your mind.
core of sun=about 10-15 million degrees
large yield nuke explosion=about 100-150 million degrees...... that's a HUGE difference.
that kang scan is a good feat, but as you said, it's a different nuke altogether.
that 'nuclear wave' scan is..... silly. it didn't even blow up up the cavern. an actual nuke of course wipes out everything for miles around. if you're going by that narration from 40yrs ago, wellll.... you're welcome to your thoughts.
as far as thor surviving a direct hit from a nuke--it's possible, as i said. i could name loads of feats that might seem greater than a nuke attack as well, but there are plenty of times where a lot less has harmed him too. we're talking about heat unlike any thor has ever been exposed to far as i know--10x hotter than the core of the sun--in a very concentrated area. i'd wager in a book if we saw him in the heart of a nuke it wouldn't end well for him unless he absorbed it.
as for wonderman--it'd be far more shocking if thor didn't fair better than he did.
