Saying it’s “crushed ice” makes these scientists sound like bartenders.

Yes, It is literally “crushed ice,” the same way playing video games is just electrons moving around. Using reductionist language detracts from the true meaning.

It’s solid ice with liquid structure. That’s a big deal. This is extremely rare on Earth, so being able to create & study it in a lab can give us more insight into how matter works off planet.

Not only water, but other transformations of matter in the universe. It’s another step toward understanding the cosmos and y’all are thinking they want funding for Mojitos. Idiocracy continues.

“To find the loosely structured, Goldilocks-density ice, the team shook ordinary water ice in a jar crammed with steel balls, cooled to about -376 degrees Fahrenheit (-200 Celsius.) 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; though it is a solid, it has the molecular composition of liquid water.”

“MDA had a final quirk: When the material recrystallized into ordinary water ice, it released a large amount of heat. The researchers believe the discovery could have geophysical implications for ice on the surfaces of frozen moons like Europa, to which NASA is scheduled to launch an orbiter in 2024.”
