Galaxy Physics in your Hands!
Galaxy Collider simulates the universe in your hands. So brace yourself for the collision of the Milky Way with the Andromeda Galaxy!
Galaxy Collider simulates the physics of interacting galaxies by computing the gravitational forces between the stars and the heavy galaxy centers.
Galaxy collider features a high performance particle engine that can interactively visualize spectacular galaxy interactions. It uses OpenGL point sprites for rendering thousands of high-quality stars at high frame rates.
The parameters of the simulation, such as the number of galaxies and stars, masses, etc. can be changed interactively to explore the infinite number of possible interactions between the galaxies.
Galaxy collider uses the build-in accelerometer of the iPad to change viewpoints and add real external forces to the simulation.

Does not work see update
I got it to run once. I have no idea what triggered that one time since repeating the action did nothing. I think it may be so slow starting because I am in a recent operating system and get a warning about that when I call it up. I really enjoyed the light (free) version and found it both mesmerizing and fascinating. I am hoping an update will get it working. UPDATE IT NOW WORKS GREAT.
I enjoyed the free version, but the upgrade was definitely worth it. The additional controls allow me to design two spiral galaxies that are distant enough that they can take a whole day to slowly strip the stars from each other's core - this is exactly what I've been looking for in a fun, visually spectacular, yet also intriguing particle toy - slash - screensaver.
The upgraded controls also allow me to try different configurations in real time - a nice change.
I think this has also given me a little better understanding of some of the more peculiar shapes we see in nebula and some of the more bizarre globular galaxies. If you set the star size to zero and the count to maximum, you can really start to see some interesting structures start to appear.
Really fun to what-if with, and an awesome way to daydream away an afternoon.
The only change I would hope for in the future would be an option to enter numerical values rather than using sliders, for trying out more precise collisions.
But it is sufficiently awesome as-is.
This is a great educational tool!
I'm a planetarium director, and my staff and I have concluded that this app alone would be a good reason to get an iPad and use it as a teaching tool. As a way to explain to people about what a galaxy is made of and how spiral galaxies can gravitationally interact and sometimes end up as elliptical galaxies, this little app is outstanding.
The 3-D feature (ala red-blue glasses) is a lot of fun and gives extra "oomph" to the educational utility of this app.
A tiny quibble - it'd be nice to be able to save interacting galaxy scenarios - sort of a "preferences" function - rather than have to start from scratch every time the app loads.
Overall, my staff and I are deeply impressed with this app. If galaxies interest you, then this is $2 very well spent.
