Big Bang, dark matter

Could dark matter have been forged in a 'Dark Big Bang?'
“The assumption that dark matter and regular matter originated in the same event, the Big Bang, is natural, given its simplicity. That is why it remained unchallenged for so long," Ilie said. "However, nature does not need to be parsimonious, abide by Occam’s razor, or by any of our aesthetic preferences."
Mysterious Dark Matter May Predate Big Bang
Dark matter, which makes up 80 percent of all matter in the universe, may have formed in the very short time before the big bang.
Just before the Big Bang, a ‘freeze-in’ event produced dark matter
Researchers have proposed a new model that suggests dark matter originated during the infinitesimally short span before the Big Bang.
Dark matter formation may have occurred before the Big Bang
A team of researchers has proposed an innovative model suggesting that dark matter might have originated before the Big Bang.
Dark Matter Could Be Linked to a ‘Dark Big Bang’, New Study Suggests
Detecting evidence of a Dark Big Bang could involve identifying gravitational waves, faint ripples in spacetime first predicted by Albert Einstein. According to Ilie, such waves might be observable through ongoing initiatives like the International Pulsar Timing Array and the Square Kilometre Array.
Mysterious 'Dark Big Bang' Could Explain The Origins of Dark Matter
Thanks to gravity, at least we're aware dark matter exists. We also know it's eerily abundant, accounting for about 85 percent of all matter in the Universe. Aside from that, though, we're pretty clueless.
New theory called "Dark Big Bang" attempts to explain dark matter
Dark matter has always been one of the biggest mysteries in astrophysics. The "Dark Big Bang" theory may have the answer.
Delayed Big Bang for dark matter could be detected in gravitational waves
Energy transition Dark matter may have been created after the Big Bang, something that could soon be tested by gravitational wave detectors. (Courtesy: Shutterstock/Tomertu) New constraints on a theory that says dark matter was created just after the Big Bang  – rather than at the Big Bang – have been determined by Richard Casey and  Cosmin Ilie at Colgate University in the US.
Dark matter may have originated before Big Bang, says study
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,
Possible origins of dark matter in 'Dark Big Bang' scenario
Recent research unlocks new clues that could radically change the world's understanding of the origin of dark matter.
Cosmological model proposes dark matter production during pre-Big Bang inflation
