I'd suggest Big Rip too, or at least, some option to simulate the expansion/contraction of space itself.
That should be awesome too.
Add Big Rip into simulation files. It will make sun explodes, even planets explodes.
Big Rip is a ripping everything that is in the center of the universe, or everywhere. It's explode effect.
First of all, thanks a lot for appraising my little idea, wubbzy301
I'd like to say that the subtle effects of an expanding or contracting space may be interesting to simulate, and probably far easier to program than the catastrophic effects. By simulating a subtle contraction of space it would be very interesting to see how orbits get smaller and eventually lead to collision (May be a must have option for those who like to "force" collisions
). The same would be true for an expanding space, to see how the bodies of a planetary system slowly lose their gravitational bond.
The catastrophic point of view of this idea is also very interesting, but from a programmer's point of view, i think the "dissolution" of stars and planets by an uniform outwards force is a difficult task (same for compression).
Those are my two cents...
