ICE 11 is most likely the ultra dense water that Mark LeClair discovered when he used lasers to generate super powerful cavitation bubble collapse. LeClair called that stuff "the water crystal" Here is the ice 11 state diagram: https://qph.fs.quoracdn.net/main-qimg-9f0f50f59a4c1e9d374a004a21565188.webp Scientists have confirmed the existence of “superionic ice,” a new phase of water that is black and hot first theoretically predicted more than 30 years ago. Although it has never been seen until now, scientists think the new state of matter, it might be among the most common forms of water in the universe. “It’s not quite a new phase of water. It’s really a new state of matter,” said physicist Livia Bove Physicists have been unlocking the secrets of superionic ice for years. In 1988, chemist Pierfranco Demontis at the University of Sassari predicted water would take on this strange, almost metal-like form if pushed beyond the map of known ice phases. This stuff is similar to the dense hydrogen that Holmlid produces in that there is a multi particle positive core and a negative particle surrounding cloud. I bet it is also superconducting at very high temperatures.
