theoretically (galaxies colliding)

[slipknotpsycho]

what would happen if two galaxies collided....

if space is infinite (which and alot of others believe) then technically, the galaxies may not be stationary and moving themselves... so what would (could, or what do you think) happen if two of them collided?

They would explode and create another galaxy or a black hole.

And all of our animals would have 7 heads and eat only cabbage.
And tiny e would finally be able to lift the HUUUUUUUGE salt shaker.

it would become a super galaxy...

The milky-way and Andromeda galaxy are going to collide in about 7 billion years. Most of the stars in the galaxy will fly right past each other(a galaxy is mostly empty space). Lots of them will be thrown out into deep space. The super massive black hole in each galaxy will spiral inward towards each other creating a even larger super massive black hole. here are some videos about the impending collision

maybe they merge into each other.

excellant post, i saw the whole show.
its an hour long. most amazing thing in the universe. a cosmic train wreck. Thats what it will look like.

that would be crazy i wonder if everyone would die. hitting another planet would suck

Earth was hit by another planet the size of mars. they say we got the moon out of the deal and a new Earth.
the original Earth Earth mark 1 was wiped out along with any trace of life it may have had.
after the collision earth mark 2 formed along with our moon and the rest they say is history.
Will it happen again? Absolutely.
When? thats any ones guess.

There's nothing theoretical about it. Galaxies collide all the time.

Well, it's very unlikely something of that size would hit the Earth in the few billion years our planet has left to live. All the larger objects in our solar system with unstable orbits have already crashed into other things or fallen into the sun. The only things left in our neighborhood that are as big as a planet are the planets themselves and their moons, which have survived this long because they have achieved orbits that prevent them from smashing into things.
