Comment on Every particle that made up your body is older than you, some of them are older than the universe

  Yes, some of the elemental particles in our body (electrons, quarks, …) were actually popped into existence along with the universe during the first fraction of time of the Big Bang, and remained still until today. So whatever or wherever these particles came from (assuming they do), they carried with them information that is older than the universe itself.

    at best, that means they’re as old as the universe, not older than it. also, didn’t most of those particles constantly annihilate each other?

    If I am not mistaken, accordingly to the Big Bang theory, all particules were created at the same time. Not before or after, or few of them but all of them at the same time.
    No new electrons/quarks/… were created since then.

      Photons are an exception (at least, in as much as that they are a particle), and you can make new particls from energy, but definitely there’s a limit to how old a particle can be. No particle is older than the universe (as far as the big bang is concerned).

        The universe in the Big Bang theory does have an age (approximately 13.7 billion years), so in a way, the Big Bang theory does not explain the origin of the universe, but rather the state of the universe 13.7 billion years ago. With that said, it is the limit of the universe, not the particles. The age of a particle could be infinity.

    I don’t think you know what either elements or particles are…

    Ah, good point. The universe hadn’t expanded yet.
