New phase of matter that acts as solid & liquid at the same time
I'm sorry that just annoys me. The solid-liquid-gas thing is a very old idea and like most very old ideas, it's a gross oversimplification. There are lots of materials that combine the properties of solids and liquids, starting with a bucket of fine dry sand, which would behave as a liquid despite being made up of solid particles.
Professionally, I spend a lot of time measuring the damping of rubber compounds, which is a measure of the ratio between them acting like a liquid and acting like a solid.
