This is what I was looking for, thank you.

But our galaxy (and we) are moving 550km/s through space, relative to the CMBR. I understand the centre is everywhere, but our centre is moving with the same speed relative to the CMBR. Are there places that don't move relative to the CMBR?

I'm not talking about size. I'm talking about the motion of galaxies relative to the CMBR.

I guess another way to frame my question is: are there galaxies that experience no redshift of the CMBR at all? (Motion of the individual stars not taken into account)

Reply to Astronomers discovered something strange about 'potentially hazardous' asteroid Phaethon by Tough_Gadfly
It's speeding up in it's rotation gradually, by 4ms a year.
Isn't it save to assume the asteroid either loses mass, or it's mass is somehow pulled towards the center? And if it's pulled towards the center, isn't a possible explanation that it has a liquid core, since rotating liquids pull mass towards the center?

But we would be able to anticipate it. It's not like it supernovae happen at random.
