Galaxy Collision HD

This is a simulation of two colliding galaxies. It took about twelve hours of computing time to simulate the three parts.

Each part is simulated differently:

The first part is computed in steps of three hundred years. One real second in the video equals three million years in the simulation (and is calculated in ten thousand steps).

The second part is computed in steps of ten thousand years, and for each second in the video nine million years have passed in the simulation.

The last part is the least accurate of the three, and is calculated in steps of one hundred thousand years. One real second here equals ninety million years in the simulation.

The program used for the simulation is "Universe Sandbox", see UniverseSandbox.com for a free download.

How did you get the galaxies to look so realistic in the beginning? And how did you render it? did you use the screenshot tool?

[TheBetaBoyz]

@TheXRealXBrapp The particle multiplier was set very high in the beginning. That's why it looks more realistic (the galaxies are much denser).

The rendering was done with the movie button (capture - movie). Behind the movie button is a box where you can choose how many time steps should be between each frame. If you turn this up, you can make the time steps smaller and your simulation more accurate.

I used version 2 of Universe Sandbox btw.

if you look closley at 0:32 you can see the iron giant

This would be fucking amazing in 3D

basicly.. they split into even tinier versions of them self and float away?

@amartinez97 cool story bro

[amartinez97]

@Yobidefy Yeah thing is you dont sound sarcastic at all in text, i actauly got the feeling you were 12 from your last comment.

[Yobidefy]

@amartinez97 yeah dont be such a smartass asshole, i was just being sarcastic about this video...

[amartinez97]

@Yobidefy Duh, exactly what did your teachers teach YOU in school?

Fly away, stars! Be FREE!

who the hell dislike that video!?

[TheStoryWeLive]

1:11 to 1:22 = 11sec, 11*90,000,000= 990,000,000,000 years!!!!!!!!!!!!!!!!! i dont even wanna add up the other years.
