## Resource

A new study in Nature Astronomy suggests that the spin of modern galaxies is a direct legacy of the early universe. Scientists found evidence supporting tidal torque theory, showing how ancient gravitational forces gave galaxies their angular momentum billions of years ago. The discovery could also offer a new way to investigate elusive cosmic particles such as neutrinos by studying their influence on the primordial universe.
