X-rays From Other Galaxies Could Emanate From Particles of Dark Matter

Posted by Soulskill on from the either-that-or-alien-xray-machines dept.

sciencehabit writes "X-rays of a specific wavelength emanating from the hearts of nearby galaxies and galaxy clusters could be signs of particles of dark matter decaying in space, two independent teams of astronomers report (first study, second study). If that interpretation is correct, then dark matter could consist of strange particles called sterile neutrinos that weigh about 1/100 as much as an electron."

    Most science fiction sounds plausible, that is why we enjoy it. We have no proof dark matter or dark energy exists, so claiming side effects is pretty stupid. Sure, it is possible but it is equally not possie. A whole segment of theoretical physicists has been working on equations that don't require dark matter or energy with promising results so far.
