Multiple-Galaxy Collision Simulation

This animation studies the effects of multiple galaxies colliding over time. Astronomers use such simulations to develop theories about the origin of today's galaxies.

i totally agree about the collision issue, but what i had in mind was the increasing chances of being exposed to γ-rays or other exotic phenomena that occur to "over-populated" spots in the universe, which are lethal indeed, for life as we know it at least :)

Yes, but your wrong:

In a galaxy the distance between planets is so vast that it is extremely unlikely that our or indeed our whole solar system will go anywhere near another

Its deliver hope from halo reach btw. The blue spartan is called kat

I would imagine when we would be less than a couple of centuries from our milky way(galaxy) and Andromeda collision.... The song of deliver hope, live action trailer for ODST and the music from avatar where the blue guy falls of the human ship during the collision :(

AHH THEY'RE CRASHING INTO EACH OTHE-no wait...that's Captain Falcon and his team training, CARRY ON!!

WOW

galaxies are dancing!

Not necessarily. A supermassive black hole might disrupt the process, but they accumulate over millions of years. No single star becoming a black hole would disrupt it in the slightest. Galaxies are riddled with black holes.

Black holes are only as massive as the part of the star that made them, plus other matter they pick up. The black hole at the centre of our galaxy probably took an incredibly long time to reach its current size.

there has got to be (proboly) hunreds of star collisions some might go to supernova and one of them might make a black hole. then that will affect the WHOLE process

[WorldWalker128]

How come we never see a simulation for a DIRECT collision? Given the 'law of averages' it's bound to have happened at least once.

1 of 3 effects: 1. They bounce off each other over and over and eventually come to a stop on one another. The stars and planets would likely still scatter regardless.

2. 1 or both would shatter on impact creating hundreds of black holes sucking up all.

3. Upon impact, all the gases collected would ignite and create a Gi-normous nova that'd blow everything up.

Somewhere in space....this is all happening right now.
