nFA, have been wondering about this a bit.
at the other forum, a member replied to a question.
he quoted me piecemeal, and replied to each piece.
I am doing my best to present it clearly here.
if this is too confusing, (and I totally understand if so),
please just scroll to the bottom of my post here.
I will write my question again.
thank you.
me: "how does and how will the expansion of the Universe affect this?"
other forum dude: "depends on what you are referring to by "this". Your question is very poorly stated."
me: "the ones that overlap and intersect with each other now, will continue to do so."
other forum dude: "no. Their centers are receding from each other way faster than their radii are increasing (*)"
me: "and the ones that do not overlap and intersect, will continue to stay separate from each other."
other forum dude: "yes"
*EDIT: my statement is not valid if the two observable universes are within a galactic cluster, since things the size of clusters and smaller do not recede from each other
ok, here is what I'm wondering about:
the other forum member said that the centers of the observable universes are receding from each other,
way faster than their radii are increasing.
is he right, or does it depend on what Dark Energy does?
