Hace 2 días · In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen.
Hace 1 día · "If the entire dark matter in the Milky Way was composed of black holes of 10 solar masses, we should have detected 258 microlensing events," says Dr. Mr.óz.
Hace 1 día · The second article, published in Nature, discusses the astrophysical consequences of the findings. “If the entire dark matter in the Milky Way was composed of black holes of 10 solar masses, we ...
Hace 2 días · This new fundamental cosmological invariance is a direct consequence of the matter field non-linear dynamics: as the universe evolves, the non-linear fluctuations of the cosmic field increase, driving the halos towards sphericity. The deviation from sphericity, measured by the prolaticity, triaxiality, and ellipticity of the dark matter halos ...
Hace 5 días · Since dark matter particles have not yet been found in laboratory experiments, the strength of their interaction with ordinary matter and the rate at which they annihilate each other are not known.
Hace 5 días · CERN’s NA64 experiment used a high-energy muon beam technique to advance the elusive search for dark matter, offering new hope for solving one of astronomy’s greatest mysteries. NA64 vacuum ...
Hace 3 días · Where is dark matter, the invisible masses which must exist to bind galaxies together? Stephen Hawking postulated they could be hiding in "primordial" black holes formed during the big bang, writes CNN. "Now, a new study by researchers with the Massachusetts Institute of Technology has brought the theory back into the spotlight, revealing what these primordial black holes were made of and ...
