Condensed Energy
Matter is condensed energy, just like liquid water is condensed steam.
If you start with an empty room and inject a bunch of steam, the steam will expand and cool, eventually forming water droplets. This is essentially the idea for what happened in the first few seconds after the big bang. All the universe was in a small area, so the energy density was extremely high. There simply was no matter, it was nothing but energy (photons?). As the universe expanded, the energy density was reduced, cooled in effect. When that density dropped below a certain threshold, some of that energy was converted into matter. First the most fundamental particles formed (quarks, as I understand things currently), then those fundamental particles combined to form more conventional particles, such as protons and neutrons. Much later, as the cooling continued, the atoms began to capture the free floating electrons, and space became transparent for the first time. (We can see the optical afterglow of this electron capture time as the cosmic background radiation.) |

Atoms are composed of electrons, protons, and usually neutrons. Protons and neutrons, in turn, are composed of quarks. (What was it, u-u-d for protons, d-d-u for neutrons?) Beyond that, any further speciaition of composition is speculative. |

Don't forget about gluons and hadrons. It could be easier to become a christian What do we agnostics say about proof?

And don't forget the charmed particle (last quark to be discovered), MACHO's, WHIMPS, muons, and nutrinos, tho you're free to forget how they're spelled, as I have. -- Albert the Traditional Catholic

Well, all those exist, but they aren't parts of the atom. That's what I was listing.

I know that the popes were wrong, and had erred--and were fallible. I'm not a Catholic. I can say that without contorting and misrepresenting reality. |

What is the point then of even having it? This is to say that the Pope IS fallible. If this pope is, then so must all the others--you cannot logically say that this is not so. And at this point, you can disregard EVERY papal decree ever. After all, he could very well be mistaken. |

Gluons stick quarks together to form hadrons which are the basic particles making an atom.
