Astronomers Witness Whopper Galaxy Collision

Raver32 writes "A major cosmic pileup involving four large galaxies could give rise to one of the largest galaxies the universe has ever known, scientists say. Each of the four galaxies is at least the size of the Milky Way, and each is home to billions of stars. The galaxies will eventually merge into a single, colossal galaxy up to 10 times as massive as our own Milky Way. "When this merger is complete, this will be one of the biggest galaxies in the universe," said study team member Kenneth Rines of the Harvard-Smithsonian Center for Astrophysics. The finding, to be detailed in an upcoming issue of Astrophysical Journal Letters, gives scientists their first real glimpse into a galaxy merger involving multiple big galaxies. "Most of the galaxy mergers we already knew about are like compact cars crashing together," Rines said. "What we have here is like four sand trucks smashing together, flinging sand everywhere.""

4 way stop?

So, how long is this going to take? What happens when the black holes at the center of each one collide? And, if as we say yesterday, they are really worm holes, what will that imply? Will the wormholes be the 4-way stop of the galaxy?

We already have that bullshit in Orlando. ugh.

Expanding Universe?

[slapout]

I thought that galaxys where all moving away from each other. How did these manage to colide?

Now, when someone can show me some live footage of two stars crashing into each other and a really big explosion, then I'll be impressed. That's exactly what some gamma ray bursts are thought to be: colliding stars. However, since they're colliding neutron stars, we can't really see them before the explosion, so all you see is a great big flash at the end. You don't see two stars zooming toward each other before they collide.
