Scientists Recreate the Universe's First Molecule, Shedding Light on Cosmic Origins

TL;DR
Scientists have recreated the first chemical reactions of the universe, focusing on helium hydride ion (HeH+), to better understand how the earliest molecules formed and contributed to star formation. Their experiments suggest HeH+ played a more significant role in the universe's chemistry than previously thought, especially in cooling the early universe to enable star formation.
