(Phys.org)—A collaborative of researchers from several U.S. universities has published a new paper that explains the major contradictions presented by the prevailing cold dark matter (CDM) cosmological model, and proposes ...
(Phys.org)—A pair of researchers affiliated with Institut d'Astrophysique de Paris has suggested that dark matter may impact light in a way not thought of before. In their paper published in the journal Physical Review ...
Researchers at Kavli IPMU and their collaborators have revealed that considering environmental effects such as a gravitational tidal force spread over a scale much larger than a galaxy cluster is indispensable to explain ...
