The invisible substance called dark matter remains one of the biggest mysteries in cosmology. Perhaps, a new study suggests, this strange substance arises from a 'dark mirror universe' that's been linked to ours since the dawn of time.
What if the world of dark matter was a mirror of our own, just with a broken set of rules? That might explain why dark matter appears to be so abundant yet invisible, a new theory suggests.
Dark matter is the mysterious, unknown substance that seems to make up the bulk of all the mass in the universe; for every 2 pounds (1 kilogram) of regular matter, there's roughly 10 pounds (5 kg) of dark matter. It doesn't interact with light or normal matter. The only way scientists can detect it is through its subtle gravitational influence on normal matter, such as the motions of stars within galaxies and the growth of super-large structures in cosmic time.
