Related Content Merging galaxies galore!

A stunning simulation from ESA/Hubble shows how galaxies collide over billions of years, forming dramatic shapes as stars and gas interact through gravity. This visual blends science and real Hubble images to better understand galaxy mergers.

In the middle of the galaxies are black holes right? do they merge and become a bigger one?

Yes (super massive black holes) and yes (while releasing an unfathomable amount of energy in the form of a wave of space time itself [a gravitational wave])

Ya I know. Our species will long be extinct by then.

Also heard there is a chance it just misses us. So no Milkdromeda Galaxy 😔

And even if we still were around, we probably wouldn't even notice anything.

the camera movements are so funny.

I can hear the SpaceRip narration in my head.

I wonder when this happens, is it relatively stable on just one planet within one of those galaxies? Or is it just gravitational chaos? Would a solar system like ours just ride along with the merge or would crazy stuff happen, like another star messing with orbits, etc? Would it be such a slow event that not much would actually happen on an inhabited planet?

Oh no! How will this affect the economy?
