Yet most people persist in assuming that their perspective and their conviction of our importance are in keeping with the external world. W hen first studying partially interacting dark matter, I was astonished to find that practically no one had considered the potential fallacy—and hubris—of assuming that only ordinary matter exhibits a diversity of particle types and interactions.
But exemplars such as this one were rather specific and exotic. Their implications were difficult to reconcile with everything we know. A small community of physicists had studied more general models of interacting dark matter. But even they assumed that all the dark matter was the same and therefore experienced identical forces.
One potential reason might be apparent. Most people would expect a new type of dark matter to be irrelevant to most measurable phenomena if the extra component constitutes only a small fraction of the dark matter inventory. Having not even observed the dominant component of dark matter, concerning oneself with a smaller constituent might seem premature. Matter interacting via stronger nongravitational forces can be more interesting and more influential even than a larger amount of feebly interacting matter.
Ordinary matter is unduly influential given its meager abundance because it collapses into a dense matter disk where stars, planets, the Earth, and even life could form.
A charged dark matter component—though not necessarily quite as bountiful—can collapse to form disks like the visible one in the Milky Way too. It might even fragment into starlike objects. This new disklike structure can in principle be observed, and might even prove to be more accessible than the conventional dominant cold dark matter component that is spread more diffusely in an enormous spherical halo. Once you start thinking along these lines, the possibilities quickly multiply.
After all, electromagnetism is only one of several nongravitational forces experienced by Standard Model particles. In addition to the force that binds electrons to nuclei, the Standard Model particles of our world interact via the weak and strong nuclear forces. Still more forces might be present in the world of ordinary matter, but they would have to be extremely weak at accessible energies since so far, no one has observed any sign of them.
But even the presence of three nongravitational forces suggests that the interacting dark sector too might experience nongravitational forces other than just dark electromagnetism.
Perhaps nuclear-type forces act on dark particles in addition to the electromagnetic-type one. In this even richer scenario, dark stars could form that undergo nuclear burning to create structures that behave even more similarly to ordinary matter than the dark matter I have so far described. In that case, the dark disk could be populated by dark stars surrounded by dark planets made up of dark atoms.
Double-disk dark matter might then have all of the same complexity of ordinary matter. Partially interacting dark matter certainly makes for fertile ground for speculation and encourages us to consider possibilities we otherwise might not have. Writers and moviegoers especially would find a scenario with such additional forces and consequences in the dark sector very enticing. They would probably even suggest dark life coexisting with our own.
