    No, they would turn into a normal bird. The extra mass is shunted into z-space where afterwards it can be called back to return the shifter to their previous form. Just don’t stay a bird for more than two hours.

    That is a weird way of saying “Humans are bigger than birds,” even then though, I think on average the ostrich will win.

    Edit: I missed the flying part, but still.

      And you missed the part about conserving mass. A bird that can fly, with the mass of a human, would be much bigger than a human (cause birds have very thin, hollow bones).

        You seem to be describing density (d = m/v). Preserving mass doesn’t really mean anything in this context without a discussion of volume.

          why would you assume density would be conserved? all I said was mass so the density would absolutely be variable.

            I didn’t. I pointed out that the person I replied was not describing mass.

    Preserving a mass while maintaining the ability to fly would require you to significantly increase in size, which comes with all sorts of drawbacks.

    Humans can’t fly precisely because we’re too dense. Birds and other flying creatures have plenty of adaptations meant to reduce mass (or, rather, density) by all means possible.

    Just because mass is conserved doesn’t mean size/shape is conserved. If you’re always human-sized, you’re a pretty shitty shapeshifter. No offense.

      thats… the whole point of the post. a bird with a humans mass would be huge. maybe you should have left your shitty assumptions in your ass. no offence.

    When I was a kid I had a book called The Science of the X-Men (which that site lists for $11 but eBay lists for anywhere from $100-1500) that attempted to use real world physics to explain how the powers of the X-Men might work.

    Mostly the explanations came down to “I dunno, maybe black holes?” For example, it speculated that Jean Grey might have a microscopic black hole in her brain and had subconsciously learned to use it to open the other end in other brains and somehow vibrate the brain matter in a way to communicate telepathically.

    Anyway, I don’t recall whether it covered any shapeshifters, but if so, it probably handled it the same way Animorphs did (as others have mentioned in this thread), but with black holes instead of z-space.

    you would need to turn into something like a Pterosaur given the hollow bones and everything. Those could be anywhere half the mass of a person to like twice the mass or something.

    Are you also preserving the ratios of materials that the body is made of? We’d have very heavy bones for a bird (or a lot of bones at bird density) and probably not enough muscle to lift 2m long wings. Also all the keratin in our hair and nails wouldn’t make many feathers. We’d be a mostly plucked bird
