| Apr 4, 2018 at 6:04 | comment | added | Alpha | Thankyou very much Ben Crowell. The linked 1998 paper concludes "it is reasonable to assume that the expansion of the universe affects all scales ... but is essentially negligible for local systems." I would still like to know whether the rate of expansion of space at a point that is say, 100 million ly from any galaxy is faster than the rate of expansion of space between the earth and the sun. | |

| Apr 4, 2018 at 5:33 | comment | added | user4552 | The second part of the question is addressed by physics.stackexchange.com/q/70047 | |

| Apr 4, 2018 at 4:52 | comment | added | Yuzuriha Inori | If I am not wrong, then you have 2 specific questions down here : 1. How mass affects expansion and 2. Are small scale structures like solar systems or galaxies expanding just like space. The answer of the second one is pretty clearly given in the answer linked by @Qmechanic. For the first part, you need to study the Friedman equations and see the dependence kn the three parameters that define our universe. | |

| Apr 4, 2018 at 3:56 | comment | added | Qmechanic♦ | This sounds like this question. | |
| Apr 4, 2018 at 3:52 | comment | added | Alpha | It's not hard to tell what I 'm asking. Here are the questions again. Is it possible that space between say, planet Earth and the Sun is actually expanding but is currently unobservable. If not, how far from our local group of galaxies do we have to look before we encounter some space that is actually expanding. | |
| Apr 4, 2018 at 3:52 | comment | added | Alpha | Which mass? Is that a serious question? I guess you don't know anything about the expansion of space. | |
