A research paper that was issued last year offers an exciting, simple and most prominently traditional answer to the secret of dark matter. The duo of theoretical physicists Professor Robert Scherrer and post-doc fellow Chiu Man Ho, working at the Vanderbilt University of Nashville, Tennessee, US, issued a detailed study on the subject of anapoles on the Physics Letters B online journal. The article mainly concentrates on the elusive Majorana fermion, a common atom that holds an exceptional electromagnetic field form, defined as an ‘anapole’. As shown in the image below, a Majorana fermion has magnetic field lines in a torus (donut) form, as opposite to the normal north-south dipole of common atoms.
Due of this exceptional EM field, the Majorna fermion would not act like a normal atom experienced in normal life. As an alternative, the Majorana fermion would not interact electromagnetically except stirring at very high speeds, meaning it would be unobservable using all EM radiation recognition equipment (like telescopes, the human eye, camera, etc). This ‘unobservability’ is precisely what the present problem is in concerns to finding out the physical nature of dark matter, which we cannot detect directly; we can do nothing other than only predicting it. Therefore, the Majorana fermion with its exceptional anapole, could be the key. The most exciting feature about the theory is that it does not depend on some new, unidentified, unusual physical phenomena. In the past, researcher has detected atoms of CS-133 and Yb-174 exhibit magnetic anapoles.
For myself, I catch the appeal of this theory lies in its straightforwardness and foundation in conventional physics. It is much more straightforward and accurate, and calls for far less resourcefulness in contrast to other theories on dark matter. An analogy could be prepared with this theory to loop quantum gravity, where the far more unusual, imaginary and absolute unscientific theories on gravity would be string theory.
