‘Scientists have turned water into ice in nanoseconds, which means really, really fast. That’s not the most interesting part, though. The ice is hotter than boiling water.
The experiment was done at the Sandia National Laboratories’ huge Z machine, which generates temperatures hotter than the sun (setting a record here on Earth) and where researchers test what we know about those plain vanilla “phases” in textbooks: solid, liquid and gas. [..]
Apparently it’s virtually impossible to keep water from freezing at pressures beyond 70,000 atmospheres,” Dolan said.’
