Researchers have proposed a new model that suggests dark matter originated during the infinitesimally short span before the Big Bang.

According to Freese and Winkler, however, a Dark Big Bang is consistent with the evidence for dark matter – as long as it happened promptly, within about a month of the first Big Bang.

A team of researchers from the University of Texas at Austin (UT Austin) in the US has proposed a new model, indicating that dark matter may have originated in the short time before the Big Bang. The theory builds on physicist Alan Guth's 1981 idea of cosmic inflation,

As physicists continue their struggle to find and explain the origin of dark matter, the approximately 80% of the matter in the universe that we can't see and so far haven't been able to detect, researchers have now proposed a model where it is produced before the Big Bang.
