Research On Dark Matter Finds No Proof Of Axions


MIT physicists have conducted the first run of a new test to identify axions—hypothetical particles that are assumed to be amongst the universe’s light-weight particles. If they are present, axions might be invisible virtually, yet unavoidable. They can make up almost 85% of the universe’s mass, in the shape of dark matter.

Axions are specifically strange in that they are anticipated to change the rules of magnetism and electricity at a small level. In a paper posted in Physical Review Letters, the MIT-spearheaded group claims that in the initial month of study the test identified no indication of axions within 0.31–8.3 nano electronvolts of mass range. This indicates that axions inside this mass range, which is equal to almost one-quintillionth a proton’s mass, either have an even smaller impact on magnetism and electricity than earlier thought or do not exist at all.

“This is the first time anybody has squarely seen at this axion section,” claims chief investigator of the research and Assistant Professor at the Jerrold R. Zacharias Career Development at MIT for Physics, Lindley Winslow, to the media in an interview. “We are eager that we can now state, ‘We have a method to see here, and we know how to perform better!'”

On a related note, scientists in Mumbai at the Tata Institute of Fundamental Research have presented a theory that assumes how dark matter might be annihilating much more quickly in our galaxy, than in the early Universe or larger or smaller galaxies.

Along with advisor Dr. Basudeb Dasgupta, Anirban Das pursued this chance since almost all studies made so far hint no signs of annihilation by dark matter anywhere—except the tantalizing hints from the galaxy seen by the Fermi gamma-ray telescope and the AMS02 and PAMELA detector. If the origin of dark matter from these signals remains, their theory might clarify why the galaxy seems to be extraordinary.
