Scaled astrophysical experiments

Definition

Scaled astrophysical experiments are laboratory-based investigations designed to replicate and understand the physical processes that occur in astronomical phenomena, using smaller, controlled settings. These experiments allow researchers to study extreme conditions like high energy density and plasma behavior in a way that mirrors what happens in stars, supernovae, and other cosmic events, providing crucial insights into the universe's workings.
