I made a simple 2-dimensional simulator of a spaceship flying near a black hole and I thought I'd share it
EDIT: I made a new version, more detailed description can be found on page 2 of this thread.
You can see the [ame="http://en.wikipedia.org/wiki/Apsidal_precession"]apsidal precession[/ame] in the picture
Forgive the poor graphics (if we can even call it graphics ), but it was just an attempt to simulate black hole physics. I'm going to improve it a bit in the near future.
You can download it here: http://dl.dropbox.com/u/7065759/Black Hole/Black_hole_old.exe
You have a spaceship orbiting a black hole at about 5 Schwarzschild radii from the center. Controls:
W/S/A/D - single press increases forward/backward/left/right thrust.
Q - thrust cutoff.
There are a few fun things to try:
1. Dropping into the black hole. You can see how the board time slows down. Also, there is one quite surprising effect, see if you can spot it and explain it
2. Lowering the orbit. This is damn hard, I still can't succeed - mostly it's poor controls, but this is the only way I could get it to work; I'll need to modify the program to make it better.
3. "Slingshot" around the black hole - now this is funny, because if you aim right, you can make a full circle and get launched again in the same direction (actual circle is very hard, I had managed to get a trajectory that intersected itself though). This is quite different to Newtonian mechanics, where you always get a hyperbola.
Hope you like it
