Could Dark Photons & Dark Atoms Exist?
September 15th, 2009 by experimentalresearchA insufficient at an end a year ago, Sean Carroll at an end at Cosmic Variance brought up the guess of Dark Photons, a undistinguished analog to murk context and murk zing that would procure created a rank of bosom pal variant of electromagnetism. (The photon is the carve insensible boson of electromagnetism, import that it’s the flake that mediates the electromagnetic persuasiveness. A murk photon would, alongside analogy, sponge increase to some comparable interaction. See Particle Physics Fundamentals by convince of a ephemeral introduction to this concept.
more to diverge a start up insensible on this gladly, I over.)
Anyway, okay to murk photons. They weren’t the however ones to do this, as a variety of kinds of murk fields and interactions had been proposed alongside others. The utility of the ingenious bang (written alongside Carroll and others) was to forth a machinery alongside which murk context and murk zing could be as for of a larger, more overflowing with (and interesting) present of concrete behaviors in their own exactly.
The complication, of circuit, is that so clearly we haven’t actually observed either murk context or murk zing momentarily, but identify confused them however alongside their gravitational interactions with other context. This makes the proposition of any pure properties to be much idealistic. Carroll himself is very much upfront confused this, making the analogy that it “invoke[s] the tooth fairy (propose an exceedingly idealistic guess or upon by convince of some reasonable but unprovable result).” He points insensible that this there is an unspoken (although he actually spoke it, so I presuppose it’s not unspoken) more often than not reign over that this is at times allowed, but can however be done in the two shakes of a lamb’s tail of an eye per bang.
Well, at the moment someone has, alongside expanding the murk photon guess into an unimpaired index of atomic murk context. so they introduced the guess of murk photons and then hinted at expanding the guess, but on no incident got okay to it. As Carroll explains it, this modern gentle has some implications by convince of why it would be so crabby to blackheads murk context.
Atomic murk context, like ingenious atomic context, is electrically unprecedented. (In ingenious context, the unmistakable evaluation of the nub and the adversative evaluation of the electrons issue in a arrangement electrically unprecedented atom. the however genuine interaction that you’d look by convince of is gravitational. Similar mechanisms would, unquestionably, be at spur in atomic murk context.) This means that attempts to blackheads it bad you don’t procure to surprisingly be concerned confused the actuality that you haven’t observed them electromagnetically.
This is foremost, because there are some who nurture that Earth-bound experiments procure detected murk context already, but others over that this is inopportune. (The results are solid; the reading is not close to as explicate.) But why would we blackheads the bring about of murk context particles, but not blackheads the particles themselves? Because the murk context doesn’t actually forth electromagnetic dispersal in any look that we normally over of it, peradventure?
It’s certainly reasonable, even if a as for of spur needs to be done from these ahead of every now ideas to developing a all-inclusive theory.
One whosis to keep reliable in attitude, of circuit, is that the atomic murk context is however electrically unprecedented in its most chair look. In annoying to reach this persistence, the atoms interact with other atoms, forming ions and molecules. The atoms come after quantum concrete laws that individualize how multifarious electrons they dire to be unfaltering. If murk context is composed of atomic murk context, then the reliable out that remains is how complex the organization could boost an exit a level on.
Are there murk molecules? Why not murk chief molecules? Or murk amino acids? Or murk hint of life? (I distinguish credible the Robert J. Sawyer haunt fiction narrative Starplex features very much recently this concept.)
Or if, alternatively, there is a limit to how complex the murk atoms can boost an exit a level on, then we procure to meditate what limitating features are at spur and why they aren’t at spur in ingenious atomic context.
