Dark Matter May Be Ordinary Matter in Parallel Spacetime Continuums – Here's Why

by Alex Vikoulov

"[O]ne new theory says that Dark Matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain Dark Matter."  –Michio Kaku

The first stars illuminated the cold and dark early cosmos, then collapsed into the black holes that along with Dark Matter formed galaxies and superclusters visible today. How do we know that Dark Matter exists? We know it exists because we can see its gravitational effect on the visible stars and galaxies. Our own Milky Way galaxy could not have dragged in enough matter to make its stars in the 13.8 billion years since the Big Bang without the presence of some invisible stuff whose extra gravity kept things together as a glue. The European Space Agency calculated that Dark Matter accounts for 26.8% of the mass-energy of the Universe compared with the 4.5% of normal ‘fermionic’ matter. It means that Dark Matter outweighs ordinary matter by a factor of about six.
