“Is the Dark Matter Signal of the Universe Buried in 20 Year-Old Space-Telescope Data?”

One new theory, says physicist Michio Kaku, is that the as yet undetected dark matter of the universe may be ordinary matter that makes up stars, planets and galaxies in a parallel universe. “If a galaxy is hovering above in another dimension,’ says Kaku, “we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain dark matter.”


“Pac-Man Black Hole Mergers” –Could Explain Origins of the Cosmic Web of Galaxies

“This could be a unique way of probing the physics around these supermassive black holes in a way that could not be probed in any other way,” said theoretical gravitational wave astrophysicist, Rochester Institute of Technology’s Assistant Professor Richard O’Shaughnessy, about simulations that could explain the origins of back hole mergers. “It offers unique insight into how the centers of galaxies grow, which is of course essential to understanding how galaxies as a whole grow, which explains most of the structure in the universe.”


Ancient Galaxy Clusters –“Dark Skeletons at Dawn of the Universe”

The discovery of a ancient cluster of galaxies at the dawn of the cosmos, the most distant ever found at 13.0 billion light years away, suggests that a large structure already existed at a time when the universe was only about 800 million years old or 6 percent of its present age. Finding a cluster this far away makes finding the needle in the haystack seem an easy task, but more importantly, it reveals “the dark skeleton of the universe.”
