Tom,
Your responses seem a bit distracted.
For instance, something within the earth's field is going to be attracted more to it, than say Venus.
I think there is an interesting point someone, not necessarily you, might find interesting to consider; That of the consequences of expansion versus contraction at an essential level.
For instance, contraction necessarily coalesces to a unit. Be it an atom, or a planet, a distinct entity is formed and surface tension makes it as efficiently formed as possible. I would even posit that light as a photon is a form of contraction, as opposed to a wave.
On the other hand, expansion radiates outward. Even possibly to the point of all material from the original source being shed, such that it no longer exists. In a sense then, it is like the proverbial wave. Like one washing through rocks on the beach, or out from a stone in the water, it spreads out and fills in the gaps between all the more solid and discrete forms.
So as gravity and mass contract and coalesce, there are not going to be particles drawn from outside the primary fields of influence, so mass is very much a global and globalizing effect, light travels everywhere it can, even washing past intervening galaxies, for billions of lightyears.
We could examine this relationship in any number of ways, such as even human affairs. for instance, liberalism tends to be like light, expanding out over and illuminating everything, but without much gravitas, while conservatism is like mass, quite solid, but loath to extend much beyond its range. One could say the Ebola virus is quite liberal in its reach, but also very conservative in the consequences it could have on humanity.
While I realize you will offer up the usual so what, I just wanted to show these discussions cause my brain to exercise itself and for that I am grateful.
Regards,
John M
