Rayleigh-Taylor instability is a phenomenon in which, when 2 fluids of different densities meet at an interface, a force acts from the denser fluid toward the less dense fluid, and disturbances grow from small irregularities at the interface, destabilizing fluid motion. It was identified by Rayleigh in 1883 and G. I. Taylor in 1950. For example, if water and less-dense oil are separated with water above and oil below, the boundary is in unstable equilibrium, and a small disturbance instantly reverses their positions. This phenomenon, caused when a denser fluid pushes a less-dense one through gravity or similar effects, is Rayleigh-Taylor instability. Rayleigh–Taylor instability is the greatest factor impeding spherically symmetric implosion in central-ignition laser fusion. It is also actively studied in material-mixing processes inside stars, such as supernova explosions. https://scrapbox.io/files/65a5e735036a120024c85605.png
