Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

Dark matter remains one of the biggest mysteries in fundamental physics. Many theoretical proposals (axions, WIMPs) and 40 ...

Superheavy charged gravitinos may be the long-sought answer to dark matter. Dark Matter remains one of the biggest mysteries ...

Only a small part of the universe consists of visible matter. By far the largest part is invisible and consists of dark matter and dark energy. Very little is known about dark energy, but there are ...

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a ...

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the ...

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...

The Milky Way center, as seen by the Spitzer Space Telescope. Image: NASA, JPL-Caltech, Susan Stolovy (SSC/Caltech) et al. Stars very close to the center of our galaxy could be fueled by dark matter ...

There was an excellent live podcast with Rajendra Gupta, Brian Keating and several others a couple days ago discussing current data and findings. Its interesting as Gupta proposed a new paradigm that ...

An astronomical "conspiracy" about how stars and dark matter interact has been disproved by scientists. This debunked theory was originally suggested to explain why matter appears to decrease in ...

Ah, I see I should have phrased my question a bit more tightly. Anyone taking Milgrom's MOND and trying to apply it on a cosmological scale is on an absolute hding to nothing from the outset, so I ...
