Lots of atoms together. So called 'reality'

Gah, I am really going to write that diary about quantum mechanics and ontology.

Re: Les Olivières (none / 0)

And I presume that 'cosmic rays' or particles will not pass through great swathes of density (like Planet Earth) because the statistical chances of hitting one of those 'knobs' ("I saw that it was impossible to get anything of that order of magnitude unless you took a system in which the greater part of the mass of the atom was concentrated in a minute nucleus. It was then that I had the idea of an atom with a minute massive centre, carrying a charge".), increase with distance through a 'solid'.

Re: Les Olivières (none / 0)

Cosmit rays are not able to pass through the atmosphere - you don't need a "solid" to stop them because they are charged particles.

Cosmic ray - Wikipedia, the free encyclopedia

When cosmic ray particles enter the Earth's atmosphere they collide with molecules, mainly oxygen and nitrogen, to produce a cascade of lighter particles, a so-called air shower. The general idea is shown in the figure which shows a cosmic ray shower produced by a high energy proton of cosmic ray origin striking an atmospheric molecule.

And ultra-high-energy cosmic rays are even stopped by the low-energy photons in the microwave background radiation (so you don't need "matter" to stop them).
