Will the milky way collide with Andromeda and create a super massive black whole?

Question

Will it create a super massive blackwhole?

Answer 1

A galaxy collision is barely a real collision. Although the distance makes a galaxy look like a densely packed structure, that is relative. The stars are so far apart in relation to their size that a 'collision' between galaxies would result in very few actual collisions of physical objects. There's enough space that the galaxies will pass right through each other. The mutual gravitation of the various stars will pull things around and probably result in the formation of a large elliptical galaxy, but the two galaxies won't collide in the catastrophic destructive sense that, say, an asteroid and a planet might.

Answer 2

Both the Milky Way and Andromeda already have supermassive black holes at their centres. It is believed that when galaxies collide, the respective SMBHs from each galaxy merge with one another, forming an even more massive SMBH!

Answer 3

It is theorised at at the centre of galaxies there alread exist a super massive black hole (or maybe more).

If 2 galaxies collide, possibly the holes will combine. But the stars floating around will continue to float around.

Answer 4

No because the milky way and andromeda are speeding AWAY from each other this is because the space between them is expanding as it cools from the big bang.

Answer 5

When to galaxies are "colliding" they are just simple brushing and combing each other. Excepting maybe that case, when they are matter and antimatter.
