Reply to comment by Kimorin in New Form of Ice Discovered – May Shake Up Our Understanding of Water by landlord2213

It’s different from regular ice. It doesn’t have crystalline structure like you can find in all other ice forms on Earth.

In space, it could flash freeze under a low pressure and at a faster rate possible than normally achievable in a lab.

Normally water has to crystallize as it becomes solid. The liquid gets cold enough and you have crystals nucleate out and then all the rest of the molecules will fall in line over time. It’s pretty common to see online people mess with this thermodynamic process and make “flash freezing” water where basically the first crystal just hasn’t nucleated yet, since it needs a little kinetic push. So it stays a liquid until suddenly boom one crystal nucleates out it immediately freezes.

This ice is like there is no crystal that nucleates, and the water just… freezes anyway. Which is not a stable state thermodynamically speaking.

It’s like forcing all these molecules in a horribly close and weird arrangement and just keeping them there.

Crushed ice is just crushed ice. Idk where you’re getting that from.

>The method is called ball milling and is a way of breaking up molecules using mechanical forces. The principle is simple: As the balls crash against the ice, the latter is pulverized. As a result, MDA looks like white powder

it's this ^

but thanks for the explanation

It is regular ice. We just have the gravity/heat assisted version

At this point, this is a silly semantic debate over what counts at “regular”.

I'd argue that the definition of regular is by total amount in the universe, you'd argue that there's no people out there to give a reference for regular, then we'd get coffee. Speed run
