Now, it looks like you are trying to change the definition of “atom”. Which I spoze, IBM did when it manipulated atoms one at a time on a crsystal matrix. But this is just one of many examples of recent experimental results challenging the conventional view, ever since the Greeks, of what passes for reality.
Space was always considered infinitely divisible, and infinitely large. But not any more.
They can create a chain of atoms, and run a charge from one end to the other of that chain, and they will all line up in an absolutely perfect straght line. It kinda fuzzes up the boundary issue. There is no doubt where the line is, and it is not infintessimally small. It has all the characteristics of the perfect boundary, but you can run a charge thru it, so it has a physical presence.
Free will is on the same slippery slope, We know a single nerve impulse can avalanche into a torrent which in turn triggers entire images in the mind. And we also know that such an impulse can be triggered by a cosmic ray hitting an atom on the surface of the dendrite. Seems that ideas really do hit people.
It dont make sense to damn people to hell cause they were hit in the wrong way.
