I hear Andromeda's black hole is 50 times larger than the Milky Way's

Andromeda does have satellite galaxies, but we are not one of them. Andromeda is roughly twice the size of our galaxy, so the black hole at the center may be much larger - I don't know for sure. We are on a collision course with Andromeda, however, so we may someday find out more (if we survive that long).

Andromeda is about 2.5 million light years away, and while it is the largest galaxy in our Local Group we are not revolving around it or its central black hole. All the galaxies in the Local Group are revolving around a centre of gravity about halfway between the Milky Way and Andromeda.

And even though many sources claim we are on a collision course with Andromeda, recent studies from measurements taken with the Hubble space telescope and the Keck I and Keck II observatories have suggested that it only appears we are moving towards each other.
The illusion is caused by the rotation of the Milky Way - our sun (and therefore the earth) are rotating towards Andromeda in our million-year journey orbiting the galactic nucleus, but our galaxy is actually revolving, along with the other galaxies around that centre of gravity for the Local Group.
We are closer to the black hole at the centre of our own galaxy.

I believe Andromeda has two satellite galaxies. Milky Way is the next largest galaxy in the local group, it is too big and too far away to be orbiting Andromeda. Also, scientists now believe Milky Way is more massive since it contains much more dark matter.

No we are not revolving around Adromeda's black hole, and yes the black hole at the center of Androme is in fact 50 times larger than the Milky Way's.

because of the fact that no one knows how great the "Universe" is i think of it relatively is totally available that we could be interior the outer bands of a great great mega galaxy or a sparkling sort of shape that we call our universe. there could be different universes available that we are able to' see. i've got considered this until now and if this mega shape replaced into 50 billion easy years huge the easy from the middle might'nt have even reached earth yet. Why do scientists no longer communicate approximately this or does the mathematics no longer upload up for something to be that great? Fianally, 4 hundred years in the past we concept the universe revolved around the earth and until now that, in a snow globe; we've been incorrect until now. perchance we revolve around something extra desirable that we cant see because of the fact the easy hasn't reached us yet. i think of that would clarify why it style of sounds like area is increasing. good? great question btw.
