For what it's worth, andromeda/milky way collision simulation

[DrPizza]

I was looking for this for an OT thread...
I thought the people in HT might appreciate some of the work done at
this site.

Some awesome animations done on super-computers of the collision between our and neighboring galaxy (although, of course, some assumptions, estimates, etc. were made) - 4 days of number crunching on a super computer for the animation results in quite wonderful art.

Several of the other videos/simulations are quite impressive to watch.

30mb 640x480 I have seen other kinds of these before, so Id like to compare. I remember watching TV and seeing that our solar system (if it stays intact) flys out of the Milkyway's orbit and drifts into nothingness.

Edit: Oh wow, the Klemperer one is 61mb.

that was pretty nuts. it makes ya wonder what would happen to the planets and stuff. all i could think of watching that was utter distruction lol.

wonder if something would come of the mixing of materials and what not. im guessing the collisions would happen at reletively high speeds.

Actually during most galaxy collisions the stars themselves dont collide. Theres still a ton of vast open space.

The huge majority of "space" is in fact empty space, most stars would never touch another star. It's also interesting to think that these "collisions" would happen over the course of (insert large number here) years.
It's interesting though, to see the gravity interactions. I wonder what would happen to planetary orbits. Would other stars come close enough to influence our solar system? If we did get flung off during the process, would that have any effect on our solar system?

On one of the sites I was reading about it, it implied that a lot of the black holes would be "fed" at a higher rate than they are now.

very cool

thanks for link!

Aside from our solar system being a little screwed up, planets would more than likely change their orbit because of multiple other large gravity wells, not much would happen. I suppose our solar system would speed up/slow down, which probably wouldnt make much of a difference in anything significant. I suppose we would have to put more/less energy into reaching light speed (objects larger than atoms), however small the incrament is.

what codec is required to play those? i get sound but no video.

ffdshow sp(?) i just got the k-lite codec pack

 

[MrDudeMan]

i never install any codecs and i am able to play it. the only thing actually installed on my computer is WM9 and quicktime.

Get Divx it's free, no hassle.

Thanks for the link, great videos.

Definitly cool stuff. Assuming our solar system didn't get flung out into space (unlikely) I'm really not sure it'd be impacted THAT greatly unless it came somewhere near the core of the other galaxy. Chances are the biggest impact would be in the travel of the solar system itself rather than a direct effect on the bodies within (earth and the other planets). Just my guess though. Although I imagine we'd see a LOT more debris within the solar system... possibly the disruption of the Ort Cloud which could mean the various planet of our solar system getting bombarded by meteors and asteroids. okay... so maybe that's not so minor.

 

[Agent11]

Ya there is no way to know until it's closer, could have little effect.
Course if the sun became a binary I think that would effect us a great deal.

repost. really.

The Milky-Andromeda...I like it.

I bet people in Andromeda are watching this.

awsome Dr.Pizza :beer: much appreciated

neato, thanks for the link.
