Superionic Ice, or Water Simultaneously Solid and Liquid, Exists
A theoretical discovery dating back to 1935 by Percy W Bridgman, superionic ice—a state of water that’s both liquid and solid under extremely high pressure and temperatures—couldn’t be proven by scientists. That is, until now. Through a process involving diamond anvils and intense bursts of laser, a super-dense form of ice transforms into superionic ice. Here H2O severs, causing crystalline oxygen to harden with hydrogen ions flowing through it as a liquid. Why is this important? It’s possible that the water on Neptune and Uranus exists in this form.
