Explanation: Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31's stars relative to background galaxies on recent Hubble Space Telescope images indicate that the center of M31 could be on a direct collision course with the center of our home galaxy. Still, the errors in sideways velocity appear sufficiently large to admit a good chance that the central parts of the two galaxies will miss, slightly, but will become close enough for their outer halos to become gravitationally entangled. Once that happens, the two galaxies will become bound, dance around, and eventually merge to become one large elliptical galaxy -- over the next few billion years. Pictured here is a combination of images depicting the sky of a world (Earth?) in the distant future when the outer parts of each galaxy begin to collide. The exact future of our Milky Way and the entire surrounding Local Group of Galaxies is likely to remain an active topic of research for years to come.

It’s Trump’s fault. And the Russian invasion of Ukraine. And the Covid pandemic.
No prob. The sun will envelop the earth long before then.
Old news...
All preparations would have to have been taken a couple of decades ago...
Women & children will be most effected...
Migrant invasions will look a lot different...
It will take at least billion of years to see anything!
Anyway, galaxies collide all the time and nothing happens.
The stars in galaxies are in general separated by few light years (Our closest star in more that 4 light years away!).
That means a lot of stars can fit in between.
So the galaxies just pass through themselves with minimal effects.
Our Milky way is currently colliding with few small galaxies!
.
Quick, hurry out and put solar panels on your Van.
That’s always the Ticket.
Let me guess, we have less than 10 years to act, and it’s going to require annihilating the middle class?
Women and minorities, hardest hit!!
I set up the lawn chairs already. Will be sitting out back for the next few billion years waiting for the sky show.
Sweeeeet!
We’re doomed. Let’s spend our way out of this.
No worries. It’ll buff right out.
50 billion years from now.
It will be millions of years before we even start to experience any gravitational pulls from it.
I’ve read theory that these two galaxies could pass through each other with not collisions of any kind, of course no one will be able kind to confirm that😀
So, maybe we don’t need to worry about global warming after all ? ? ?
“Good, we’ll get a fresh sun to replace ours.”
Well, it needs to run on wind or solar energy.
Damn. Looks like I bought extra cans of green beans for nothing.
Actual collisions of stellar masses are extremely unlikely given the very low densities of both galaxies. With high relative velocities, probably even more unlikely a passing pair of stellar masses would be pulled into a degrading binary orbit that might lead to a collision.
What’s extremely likely to happen is existing binary and greater multiple systems being pulled apart, and many stellar masses (as in, billions) being slingshotted into different galactic orbits, or with enough velocity into intergalactic space.
The telescopic views will be outta this world!!
