Certain galaxy patterns might encode whether the Universe’s primordial density fluctuations were quantum or classical in nature.
The distribution of galaxies in the Universe might trace its roots to tiny primordial density fluctuations that were magnified when the cosmos ballooned roughly 10−35 s after the big bang. Many argue that these fluctuations were quantum in nature, while others think that they could have had a classical origin. And, cosmological observations are—so far—consistent with both stories. Now, researchers propose a new test that could settle this debate.
