We Know Simple Fluids Can Flow. Turns Out, Some Can Fracture.

Context

That sharp crack, described in this piece from 10 July 2026, upends a long-held rule of physics: the idea that simple fluids only flow and never fracture. While scientists previously thought only elastic materials like rubber could break this way, these findings suggest that under enough stress, even common liquids can behave like shattered glass. The discovery reveals the hidden molecular bonds that keep the physical world together, suggesting that the line between a flowing liquid and a brittle solid is much thinner than anyone realized.
