    That would be awesome. And im sure it exists. But of course there is limits on function in those animals.

    What do you have to say to this?

    A few atoms thick? Since a few atoms do not make an "animal" I guess you mean it's built of smaller stuff, grapples atoms and takes bites out of them...?

    Reminded me of this simple machine.

    As long as there's smaller stuff then I guess you'll find animals down there. Not atomic scale though.

    Maybe they would be made not of atoms but of evolutions of smaller bites of energy, the atom could actually be the head and the evolution of the energy around it would be the functional bits. Razor sharp quantum claws that can snap off a high energy electron and "metabolize" the drop in energy as it elevates a store of energy deeper in to the super structure, than booting that electron like the worlds smallest deuce. Finally it pulls that energy back and uses it for mobility. It would probably not mate but replicate through some sort of splitting. Its niche location would be somewhere that there was an abundance of energy but no way for more macro life forms to serve in the redistribution of said energy. somewhere like ??

    Unlikely. But what about life on a neutron star? Maybe the cheela approximate your notion closely enough:

    Are there physical size limitations for small living things? What are the factors that determine just how small an animal can get? If atomic scale life needed water to exist then it should be larger than the size of a water molecule, no?

    Got to be bigger than that, cell membrane is thicker than that- so is protein, so is DNA, RNA, even virus. So no known or remotely plausible Earth life meets this description.

    So bigger than a molecule, makes sense to me.

    Methinks, possibly since this is in the philosophy forum that the OP is intimating that matter is alive or possesses some kind of life force or component..

    All that matters for something to be considered alive is:

    A. Capable of reproduction
    B. Capable of response to environment, ie not falling prey to entropy
    C. Capable of evolution

    A cell is not required for life, nor is a membrane, nor is DNA... see ribozymes

    Yes, but in practice, there is a lower limit in size beyond which structures capable of this cannot exist.

    Unless we find something which meets A, B, and C composed of subatomic particles, which is essentially what the cheela are.

    I liked it. Forward had a gift for describing exotic settings and an excellent background scientifically. The human characters are sort of reminiscent of the old "pulps", plucky, cheerful explorers out of the same mold, i.e. NOTHING like most people I have ever met.

    In a way, that is refreshing too.
