Well, it’s Tuesday, and for reasons (or, rather, causes) that are unclear to me, I had a particularly poor sleep last night.  I just didn’t feel sleepy.  Even this morning, when I told myself I needed to buckle down and get some shut-eye at least, I was only “out” for a few moments.  I even felt, or worried, that I had overslept somehow, if that’s believable.  But when my eyes snapped inevitably open, I saw that maybe 15 minutes had passed.

Eventually, even someone as stubborn as I must give way to the brute facts of reality, so I gave up and got up.  Of course, even if one doesn’t decide to “give way”, it doesn’t change anything.  Reality doesn’t depend upon the approval or acquiescence of conscious beings, however they might like to flatter themselves that it does.  It simply is whatever it is.  That’s what makes it reality.

This is a good thing, of course.  If reality could simply be changed by the power of a mind‒for instance, my mind‒there would be many, many people who failed to signal or otherwise drove badly who would simply disappear, never again to be heard from by their friends and loved ones*.

In reality, though, if one wants to disintegrate someone, it’s a somewhat laborious and messy process.  As far as I can tell, there is no way to make something like a phaser from Star Trek that can just scatter someone into particles, or whatever it is that phasers do.  Trust me, I’ve thought about potential designs on and off over the course of decades.

You can’t shoot a beam of gluons because they self-interact and are not found outside the nucleus (or a quark-gluon plasma), which is why the strong force has such relatively short range despite having a massless force-carrying boson (i.e., the gluon).

One also cannot shoot W or Z particles, perhaps hoping to initiate some form of decay.  Those bosons interact with the Higgs field, and so they have mass‒quite a sizeable mass for force-carrying particles.  And the W bosons even have electric charges.  So they don’t have a range much longer than the size of a nucleon, if that.

One could accelerate neutrons; or rather, one could accelerate parallel and matched electrons and protons and set them to collide with each other and continue in their initial trajectory as newly formed neutrons (plus some neutrinos).  Depending on their speed, they might just break apart some larger nuclei (or raise the atomic numbers of some others, à la the S process and R process nucleogenesis such as occurs in supernovae and neutron star collisions).

This could do some damage, I guess.  One might even be able to make it lethal if it were strong enough; and it might be a delayed death, which could be useful for assassins of one kind or another, I guess.  But if you wanted to disintegrate someone, you’d have to cause a very large explosion, which would not treat you kindly if you were anywhere near.

If you could generate a beam of antimatter‒positrons or, worse, antiprotons or antineutrons‒you could certainly obliterate someone if you had enough.  But it would be an even worse explosion than the neutrons would give.  A person’s mass, annihilating with an equivalent amount of antimatter, would yield far greater explosive force than any nuclear weapon ever detonated (even the Tsar Bomba, which only involved the conversion of about 5 pounds of matter into energy, much smaller than any adult human).

So, yeah, instant disintegration by a ray gun (or a beam from the eyes like in comic books) using anything we currently understand is unworkable for various reasons.  Whether dark matter particles (if they exist) or even neutrinos (which do exist and do have quite peculiar properties) could be made to disintegrate someone is far from clear or promising.  In any case, they would be likely to lead to some manner of explosion such as mentioned above.

You wouldn’t want to do that in traffic.  The whole point is to delete people who needlessly make driving less safe for those around them!  You would cause more harm than good, by quite some margin, if you obliterated them, however satisfying it might be to turn an inattentive driver (and their car if they are alone**) into a small but very powerful explosive.

Wow.  I guess this is the sort of stuff that goes through my mind when I sleep very poorly, huh?  It makes me feel a bit like writing some on HELIOS.  I could explain why but that would give potential spoilers for the book, in case I ever write it.

Oh, well.  I hope you all have a very good day.  But do use your signals when you drive, for goodness’s sake.

*I know, I’m being unreasonably generous.  Of course, people who don’t signal properly when they drive don’t have friends, and it’s all but certain that no one loves them.  Whether they are, themselves, capable of love is open to debate.

**If they are not alone in their car, or on the road, it would be too dangerous to obliterate them in situ, in terms of collateral damage.  Perhaps the neutron beam that is only lethal after a delay would be useful for that after all, doing damage that only has its full effect over time.  One could similarly use X-rays or even gamma rays for that, but their penetrating power makes it much harder to avoid hitting innocent people.
