$\begingroup$ Gravity compresses space which is what draws things into its path of concentric rings of space-time, this is seen in the multiple rings of an accretion disk, it wouldn't create expansion with gravitationally bound objects but all galaxies that are not bound are moving away even if they are still flowing to a cluster.. anyways like you say its hard without more evidence to prove it. thanks for taking the time to answer. $\endgroup$
