Colliding Black Holes (Andromeda-Milky Way collision) and Red Giant expansion

[monmarfori]

Every a billion years. the black holes will be collided. that is our fate. This is called Andromeda-Milky Way collision. 2 galaxies collide. supermassive black holes will orbit and merge. This is called Milkomeda. a proposed merged galaxy. This collision occurs 2.5 billion years and merger is 5 billion years. 400,000,000 years before the red giant expansion of our sun is 5,400,000,000 years.

Just as I said at the other topic I forgot:

We can still see Milkomeda.

Proposed?

[monmarfori]

Collision happens 3 billion years. and sun is in 5,400,000,000 years. or 5.4 billion years.

[atomic7732]

It WAS proposed, now it is overall accepted.

[monmarfori]

Really true.
