Or do right-handed neutrinos and left-handed antineutrinos exist as separate particles?

It did not have to blind or obscure if a person simply realized that it was made up of separate particles.

The fundamental assumption of the method is that the material consists of separate, discrete particles.

How did the overall general properties they'd been dealing with somehow emerge from the action of a whole lot of separate particles?

And having neither beginning, middle, nor end, each separate particle yet appears to have a limit in relation to itself and other.

Between finger and thumb, each separate particle seemed to crawl, like a tiny maggot.

Then one learns that these atoms are themselves made up of tiny, separate particles, and full of empty space themselves.

It is unreasonably difficult to get 3 separate particles to collide simultaneously, so the exact reverse of this never happens to a significant extent.

A father claiming to be a physicist claims that I cannot model the neutrons and protons as separate particles.

Well, the air is thin enough to behave like separate particles at that distance.
