“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.”

The Higgs Boson –“Gateway” to the Dark Universe?

Higgs Field

 

The cosmos contains a Higgs field—similar to an electric field—generated by Higgs bosons in the vacuum. Particles interact with the field to gain energy and, through Albert Einstein’s iconic equation, E=mc2, mass.The Standard Model of particle physics, although successful at describing elementary particles and their interactions at low energies, does not include a viable and hotly debated dark-matter particle. The only possible candidates, neutrinos, do not have the right properties to explain the observed dark matter.

Cosmic Enigmas at South Pole –“Long-Sought ‘Dark Matter’ or Unknown Frontier of Astrophysics?”

 

Blazar

 

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…)

“A Darker, Deeper Cosmos” –Looking Beyond the Standard Model

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

ESA Black Hole Image

 

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.
