The model that Dr Freese and her co-author Martin Winkler explored would explain why dark matter might be completely decoupled from traditional matter and it also naturally produces SIDM candidates. If there was such a Dark Big Bang, it would have left a clear signature\u2014a pattern in the frequencies of the gravitational waves that hum across the universe\u2014that could be picked up by future gravitational-wave detectors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr Freese has also made the case for a Dark Big Bang that could have given rise to dark matter independently of normal matter in the days after the Big Bang.
