The bad news is The Andromeda Galaxy and The Milky Way Galaxy are on a collision course. Andromeda is heading for us at about 400,000 miles an hour.
But it’ll be sometime before it gets here.
I don’t have any worry about a collision with the Andromeda Galaxy. The key word is, “SPACE.” Our two galaxies should be able to “collide,” with not one celestial body hitting another. Now, the two galaxies could join, which might make it more likely for a collision of bodies, but SPACE will still be a great factor.
