Water Is WAY Weirder Than We Thought

Water, a common yet complex compound, exhibits unique behaviors that intrigue scientists. It has two liquid phases under extreme conditions, potentially explaining ice's buoyancy. Water's glass phase, abundant in the universe, lacks a clear transition temperature, complicating its study. Quantum mechanics play a role in water's behavior in biological systems, affecting viscosity. Understanding these phenomena could advance scientific research.
