And what the heck are these 'positive' and 'negative' magnetic fields Magneto and Polaris are talking about? By Maxwell's Second Equation, magnetic field has zero divergence: there are no positive nor negative sources of it (IOW, there are no magnetic monopoles).

Also want to point out that Doomsday was amped.
So which is it? Is Superman killing Doomsday with nothing left in the tank? Then why can't anyone else replicate it - Dead Martha Wayne, Uncle Ben's corpse, Aunt May etc etc?
Carver, hello!

In fact, just last Monday I applied a 20-microseconds long, 500 MHz radio-frequency (RF) pulse on a cooled water sample sitting in an 11.7 tesla magnetic field using a Fourier-transform (FT) NMR spectrometer. I set the RF pulse power so that the pulse generated exactly a 180° nutation (i.e. inversion) of the nuclear magnetization of the hydrogen-1 nuclei (i.e. protons) in my H2O sample. This had the effect of inverting the populations of the two proton Zeeman energy levels (proton is a spin-½ particle, so it has two Zeeman levels, referred to as the "spin-up" and "spin-down" levels). This population inversion is equivalent to inverting the absolute temperature of the proton spin system.
The resulting absolute temperature of the 1H spin system of my cooled water system, persisting of the order of 1 second, was:
T = -275 K.

alway impressed with your post
you are the premium version of astner
so below absolute zero is actually possible IRL?

The experiment I did is well-known in science, and very easy and fast to perform -- assuming you have access to a modern $1million NMR spectrometer or an MRI apparatus, of course. In fact, achieving negative absolute temperatures in nuclear spin systems is one of the "basic" examples given at Wikipedia, see:
https://en.wikipedia.org/wiki/Negative_temperature#Nuclear_spins
There's nothing particularly impressive in the resulting water sample: for most intents and purposes it'd feel like water at +275 K (since most degrees of freedom of its water molecules would remain at that temperature). Theoretically it'd feel ever-so-slightly hotter than that, but in practice the difference is unobservable.
IT'S ALL CANON.

Human Porcupine was from 1962
Human Octopus was 1959
Human Flamethrower, Elasti-man, TurtleMan - they're all PreCrisis.
Also, WW is not the mightiest hero. Lol@DC going out of their way to emphasise that.
Edit: Also, Zha-Vam is PreCrisis as well.
