      I very slowly zoomed in on the actual words in the post.

      Started off processing “molecule” as “mole”, “solar system” as “galaxy”, and thinking “ha, don’t know if that’s true but it sounds both plausible and neat”.

        There are definitely more hydrogen atoms in a mole of water than stars in the Milky Way.

        The Milky Way has somewhere between 100 and 400 billion stars according to Wikipedia (1*10^11 to 4*10^11). A mole of water has 6.022*10^23 molecules in it, each of which has two hydrogen atoms in it for a total of 1.2044*10^24 hydrogen atoms.

        10^24 / 10^11 = 10^13 which is ten trillion. So, a mole of water has roughly ten trillion times as many hydrogen atoms as the Milky Way has stars.

    • Number of hydrogen atoms in a single molecule of water (H2O): 2
    • Number of stars in our (ENTIRE) solar system: 1

    That’s the joke.

    There are fewer hydrogen atoms in a single molecule of water than there are fingers on my hand.

    Check and mate.

      We can’t make plasma dense enough to have significant convention over radiance, and the longest active run is only a minute or so. We’re a good way away from plasma stable enough to be called a star, although it’s getting closer. Hydrogen bombs are probably the closest we have so far.
