Scientists Uncover Hidden Force Driving the Universe's Hottest Fluid

New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, the hottest fluid in the universe created when atomic nuclei collide at near light speed. This acceleration, previously overlooked, helps drive the plasma's explosive expansion and may influence its temperature-like behavior, particle spins, and how matter transitions between fundamental states. This finding, published in Nuclear Science and Techniques, offers new insights into the conditions that existed shortly after the Big Bang.
