In the lab, they want to recreate the birth of the universe in a cloud of supercooled gas—and for the first time see how quantum ripples at the Planck scale dampen some waves and amplify others. This trick will help peek behind the scenes of the Big Bang without telescopes or rockets.
🎯 The gas is cooled to a few billionths of a degree above absolute zero—so cold that even the cosmic microwave background, cooled after the Big Bang, feels hot.
