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


"Hidden Matter of the Universe" --Signal May Be Buried in 20-Year-Old Spacecraft Data of the Cosmic Web (Weekend Feature)


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.”

“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.”
