Big Bang’s hot secret: Here’s how first microseconds of early universe behaved

Scientists have advanced understanding of quark-gluon plasma, the superhot matter present shortly after the Big Bang. Using lattice QCD and Monte Carlo simulations, they created an equation of state for this early universe plasma at high temperatures. Unexpectedly, they found that quarks and gluons weren't behaving like free particles even at extreme temperatures, with the strong force still dominant. This insight refines models of the universe's earliest moments and matter formation, showcasing the impact of advanced computational techniques in cosmology.
