If I understand the article correctly, they found a phase transition reaction, a chemical reaction that occurs in liquid water below 0 C that splits the body of liquid water into one continuous region of high density and one of low, so its no longer a uniform liquid.
This would also release heat, like the freezing reaction (and unlike random rearrangements of molecules in the liquid).
Okay thats wrong they didnt find that. Looks like just did some ml and it suggested that such a reaction exists and what the two species are.
Also its unclear whether during the phase transition there really is two seperate macroscopic regions as opposed to a mixture (maybe like a suspension)
But what if we find the exact same face in different rocks or pixels? I also think the researchers were aware of this issue as the article mentions they were careful not bias their model.
