Dark Matter –“May Be Older Than the Big Bang”

Dark Matter

 

“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 2019 University of Tokyo study that proposed the axion as a candidate for dark matter. The only fundamental scalar quantum field that has been observed in nature is the Higgs field-a field of energy that is thought to exist in every region of the universe.

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.”

In 2018 a team of physicists linked to the massive IceCube Observatory detector buried under the South Pole, and to a command center at Penn State University, advanced satellites, and several land-based observatories, pinpointed the first known cosmic source of a neutrino, a ghost-like particle that passes through virtually all matter on Earth. It’s estimated that each second there are about 100 billion neutrinos passing through your body. (more…)

Dark Matter Filaments

 

Could dark matter particles the size of galaxies exist, or a anti-gravitational force field we call “dark energy” that might be getting stronger and denser, leading to a future in which atoms are ripped apart and time ends?

“Unknown Dark Object” –Burst an Enormous Hole in the Milky Way

An enormous “something” more massive than a star, appears to have torn a hole in part of the Milky Way’s halo. The “dark substructure” was found in data from Gaia spacecraft observations—a mission producing the most detailed 3D map of our galaxy—with Harvard’s Ana Bonaca noticing a perturbation in a tidal stream. Bonaca is a leading authority on how the tidal field of the Milky Way galaxy disrupts globular clusters, and what the resulting debris can tell us about the underlying distribution of dark matter.
