“Dark Matter Particles as Big as a Galaxy”

“At first, we thought it was absurd,” said theoretical physicist Asimina Arvanitaki, at the Perimeter Institute for Theoretical Physics, who proposes that black holes can be thought of as nature’s particle accelerators, and how we may be able to discover new particles through detection of the gravitational waves black holes create. “I’m not surprised. How else could you respond to the idea that black holes generate swirling clouds of planet-sized particles that could be the dark matter thought to hold galaxies together? We tend to think about particles as being tiny but, theoretically, there is no reason they can’t be as big as a galaxy.”

Strange Lightness of Dark Matter –“It May Be Older Than the Big Bang”

“We do not know what dark matter is, but if it has anything to do with any scalar particles, it may be older than the Big Bang,” says astrophysicist Tommi Tenkanen at the Johns Hopkins University, who was not part of a new University of Tokyo study that proposes the axion as a candidate for dark matter.

Dark Matter –“May Be Particles From Eon Before the Big Bang”

“If dark matter were truly a remnant of the Big Bang, then in many cases researchers should have seen a direct signal of dark matter in different particle physics experiments already,” says astrophysicist Tommi Tenkanen at the Johns Hopkins University.

“The Last Holdout” –LHC Scientists Seek Portal to the ‘Dark-World’ Unveiled By the Higgs

“One particularly interesting possibility is that these long-lived dark particles are coupled to the Higgs boson in some fashion—that the Higgs is actually a portal to the dark world,” said LianTao Wang, a University of Chicago physicist, referring to the last holdout particle in physicists’ grand theory of how the universe works, discovered at the LHC in 2012. “We know for sure there’s a dark world, and there’s more energy in it than there is in ours. It’s possible that the Higgs could actually decay into these long-lived particles.”
