I’m fascinated by atoms, they’re the building blocks of everything and yet most of an atom is nearly all empty space, well it’s actually quantum fluctuations, more on that later. So everything you see is largely empty space and nothingness. And yet it has mass. If you took all the core and electrons of all the atoms of humanity, it would fit in a teaspoon, see we ate nearly all empty space. Apparently now they have worked out how much everything in our galaxies weigh, that’s the planets, the stars, everything.
Just to get an idea of how small an atom is, you could fit 500,000 atoms across the width of a human hair. But that’s not the end of it, there is even smaller things in an atom, quarks and electrons.
Anyone else fascinated with atoms ?

atoms are made of only three particles.
protons
neutrons
electrons
Each of which are made of smaller particles such as quarks.
Everything is held together by electromagnetism. Without this force we would all fly apart. |

Fly apart to where? Where does it all end? |

Fly apart to nothing.
It's dangerously close to string theory. None of which I can even begin to understand. |

I know nothing, I'm chemist not a physicist, but beyond any theory, what actually stops things? Where are the walls and why are we here, what is thought and consciousness, surely fab isn't the real meaning of life....? |

"I find it fascinating. I read how to teach quantum physics to your dog lol. My dog wasn’t impressed but my son is reading it now! "
I often think the boffins that work all this out have a good sense of humor.
Quarks (of which there are only 6 currently known) combine togethet to form particles called "hadrons". |

Electromagnetism stops things. It's the strongest force. |

If you haven't already, read "A Short History Of Nearly Everything" by Bill Bryson, stuffed full of facts like that but explained quite simply. |

Sign up to do the OU physics degree. You’ll love it. |
