Can Superman punch through the crust of a neutron star?
Two issues need to be considered: Is there no limit to the proportional augmentation of power relative to the closeness of the sun? Light’s intensity does not diminish with distance, it’s just that the wave spreads away and the amount of radiated energy becomes less dense. That is to say, once in outer space and close enough to the sun, his body will be receiving as much radiation as it could get even if he was in the very surface. In other words, I do not believe superman’s power become nigh-infinite if he reaches the core of the star. He’d reach his limit much, much before. The second issue is that we’ve seen supes taking damage before, providing a strong enough source. There’s no way his body would resist the ridiculous heat and brightness in the proximity of the sun, let alone inside of it.
