If dark matter consists of new particles that were born before the Big Bang, they affect the way galaxies are distributed in the sky in a unique way. This connection may be used to reveal their identity and make conclusions about the times before the Big Bang too,\u201d says Tommi Tenkanen, a postdoctoral fellow in Physics and Astronomy at the Johns Hopkins University and the study\u2019s author.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dark matter, which researchers believe make up about 80% of the universe\u2019s mass, is one of the most elusive mysteries in modern physics.
