While particle theories are currently the most favored explanations for dark mater, physicists have still been unable to detect dark matter particles in ways that would confirm or contradict these theories. Some theorists ...
(PhysOrg.com) -- "In many ways, the standard model of cosmology works very well," Jose Cembranos tells PhysOrg. "However, there are very basic features that we just do not know. We have dark energy and dark matter. They dictate ...
Could one of the biggest puzzles in astrophysics be solved by reworking Albert Einstein's theory of gravity? A new study co-authored by NASA scientists says not yet.

A team of researchers from the U.S., New Zealand, Australia and Germany has found evidence suggesting that a type of star formation near the center of the Milky Way is responsible for large gamma ray emissions, not dark matter. ...
(ScienceX)—It was another good week for physics as an international team of researchers discovered strange forces acting on nanoparticles, which were related to looking at the Casimir Effect using quantum field theory. ...
Standard cosmology—that is, the Big Bang Theory with its early period of exponential growth known as inflation—is the prevailing scientific model for our universe, in which the entirety of space and time ballooned out ...
