    Gravity/density equation? Giant ball of water

    Can you help me find the equation for determining density when also taking the object's own center of gravity into account? For example, say I have an Earth-sized volume of water (or pick any simple spherical object). You have to account for the increase of density as you go closer to the center...

    How abundant is each elementary particle in nature?

    ...and what form may they found normally? Somebody asked me just how many of the particles we know are possible (say, delta baryons) can be found in nature and what is their usual state - are there many particles to be found outside of atoms? Although there are enough "abundance of elements"...

    Is Erythrocruorin red? (aka earthworm blood color)

    Some grade shool books claim that earthworm blood is red because it has hemoglobin, like ours. Now right away you need to clarify what "hemoglobin" can mean. I'll start off by saying that IMO it is incorrect to use the word for every oxygen-transporting protein. Moreover it is false to assert...

    Couldn't you unify gravity & the cosmological constant?

    Great! thank you so much for humoring me and sacrificing some of your time to give a proper answer :D Yes, I agree, my problem seems to boil down to trying to interpret the expansion and the cosmological at least partially as something else (ie. an illusionary difference between forces) and the...

    Couldn't you unify gravity & the cosmological constant?

    For example, here is an example of the kind of disproof that I am looking for. Fundamental forces can propagate at the speed of light, which the expansion of the universe is not bound by. Since we have clear proof that gravitational waves exist and they also propagate at the speed of light, as...

    Couldn't you unify gravity & the cosmological constant?

    Right. This is exactly my understanding. No, I did not start out with an idea about "motion". (In fact, I feel a little insulted becaue I said no such thing. :D ) That would have been a very basic mistake. We can skip the rubber sheet stuff. But when you say "growth of distances between objects...

    Couldn't you unify gravity & the cosmological constant?

    This observation could use some elaboration. :) I appreciate the response, but you realize you are not helping me understand anything if you do not say why this is true? :) (Clearly my goal here is not to demonstrate how I have overthrown Einstein with grade school logic, but to better...

    Couldn't you unify gravity & the cosmological constant?

    ...through inertial mass, namely to explain away the sameness of inertial and gravitational mass? If you assume that only inertial mass is a "real" effect, then gravity would simply become a fictious force arising from inertial mass holding matter back from expanding alongside spacetime during...
