Sorry, same music Arrow keys to move the blue planet Space to mark the movement of the planets Cool thing: If you collide the planets with one another perfectly, they'll go infinitely fast (the distance between the 2 objects is 0, and anything divided by 0 is infinity). This is why we have to pray there is no such thing as a singularity.
This is a simulation of 2 equally massive planets orbiting one another. My code couldn't work with clones, so I just made 2 planets and called it a day xd. If you don't move the planets at all you'll see something interesting. The planets will gradually go further apart from one another but come closer to a certain point. When they are practically intersecting the point, they fling each other out from orbit. You could say this is an accurate representation of 2 black holes if they didn't murder everything in their path.
