If the universe is expanding. And the space between galaxies

Because universe is actually just one big moba

which lane is andromeda and the milky way on??

>>8727195
i walk the road of vengeance

>>8727216
the milky way has been farming dwarf galaxies in the jungle and andromeda is coming to gank it

I think it's this:
The [actual] space between the Milky Way and Andromeda is expanding at a slower rate than Andromeda is travelling [through space] towards the Milky Way.

But I'm no astronomy pro, so perhaps I misused some of the terms...

>>8727149
In general galaxies are spreading away from the center of the universe but the gravity of our two galaxies has them heading for a collision course while our galaxies are travelling away from the center of the universe in tandem.

>>8727149
Because we are in a "neighborhood" with Andromeda and gravity pulls them together while the rest of the universe continues expanding.

You're thinking in three dimensions, which is a fundamental flaw

>>8727477
There is no spatial center of the universe

I don't understand what they mean by "space is expanding."

Do they essentially mean more "vacuum" is opening up between particles/quanta, but all actual quanta remains the same size/amount?

When I imagine stretching a tapestry or whatever, I imagine the dots on the tapestry getting larger. They're part OF the tapestry. Like, if space is uniformly expanding, why isn't the space between stars expanding within one galaxy? Why isn't the space between individual molecules in a lump of matter expanding? Is it?

>>8727580
Whatever force is causing the "tapestry" to expand is overpowered by shit like electromagnetism and sufficient gravitational forces

>>8727593
Ohh okay, that's kind of what I figured - the "force" that is "multiplying" the volume of space IS universal, it's affecting the whole thing, but at local levels the normal forces just negate it as it's happening.

So, like, everything's wiggling apart, but galaxies and ordinary objects tighten back together and remain globbed up, and retain their inertia, so you only really notice the extra space on the macro scale.

That's pretty cool. Probably butchering it, but hey.

>>8727598
Yeah you kind of are, but you're getting the gist of it

>>8727149
Dark matter is in equilibrium with gravity. amirite /sci/?

>>8727619
yes, otherwise niggers would fly apart

This makes sense I guess.

This too.
