A Place Where Gravity and Dark Energy Equalize

[wolram]

There must i guess be places where neither gravity or dark energy dominate, places where the pull of gravity equalls the push of dark energy, if that is so, then would these places be a good place for dust to gather?

Hi Wolram,

My guess is that these would not be good places for dust to gather, because they are inherently unstable places. Move a tiny distance inward, and the dust will begin infalling due to the excess of gravity over expansion. Move a tiny distance outward, and the dust will begin to move away in the Hubble expansion flow.

If anything, I might expect lower dust density at the zero-gravity point than in adjacent regions.
