Some considerable time ago, I proposed a Particle to fill the space available in the early versions of Dark Matter hunting. The Petrino had various qualities that didn't get any bites from the scientific sea, but still, it seems to sit comfortably enough with its potential ingredients. So I'd like to bring it back to the surface and re-dress it a bit, to see if there are any interested fishing parties who might want to take it seriously.
My problem with the standard approach to the Dark Matter problem, then as now, is the fierce dependency on constants. Dark Matter isn't likely to be found in the list of usual suspects - it's been around a long time, escaping detection until very recently. So to catch a glimpse of it, parameters have to be set outside the familiar box.
Scientists strongly suspect that neutrinos can 'skip' dimensions as they travel - they are not at all sure how they do this, but they do know that Neutrinos oscillate (change from one form to another) as they fly along at something around the speed of light. There was a lot of debate in 2011 as to whether they travelled faster than light, which caused some flurries in scientific underpants, since a host of evidence seemed to point to the possibility that they do. Then the doors slammed in 2012 with 'debunking' claims that the humble Neutrino meekly obeyed the Constant, after all. From that day to this, nothing further on the subject has been mentioned.
Dark Matter has to be composed of something other than known particles, something which interacts in a completely different way. The particle in question doesn't have to have any measurable relationship with any other particles, as it won't be interacting with them. I suggest the concept is connected to thought, to consciousness, and that once the nature of Dark Materials is cracked, scientists can start to piece together the fundamental operations of life itself, in the highest realms of spacial places.
I'm not the first to think along these lines. But when you find the Dark Matter particle to tick all the boxes I proposed in 2013, please be sure to call it the Petrino, and credit me, because I thought of it first. Thanks.
