Reply to comment by Busterwasmycat in Does the metal in the solid core of a rocky planet have any special properties? by VillagerNo4

I found this article which sounds quite interesting: https://www.universetoday.com/153356/theres-so-much-pressure-at-the-earths-core-it-makes-iron-behave-in-a-strange-way/
Sounds like it does have special properties after all.

Basically all matter acts differently in different pressures. Water freezes on Mars at 31.5 degrees and boils near 33 IIRC. Stars literally cause atoms to fuse and make new heavier atoms and all the energy we rely on that comes to earth from the sun.

So yes it's certainly special compared to the properties we know at 1 atmosphere of pressure. I would say it's still the properties of these elements and just a special environment that brings out their rare for our environments traits.

That is interesting and pretty much supports the "we don't know a lot" idea. Not something easily studied.
