I've heard people tell me that there are professional pool players who can pocket a full triangle of 15 tightly packed billiard balls on a single break. But based on what I read in this article, it sounds unlikely that anyone can pocket more than 7 balls on the break. However, if the cue ball was struck with superhuman speed, then perhaps it might be possible to pocket all the balls, because the balls would move greater distances, thereby covering more territory (I think this would be an interesting experiment for Myth Busters to test). In order to test this theory, I simulated many different breaks, by launching the cue ball at various speeds and angles. The slowest scenario I found that could pocket all the balls had a cue ball initial speed of 34 mph (real life players can strike the cue ball up to about 27 mph). The fractal image on the left summarizes the results. You may notice from this image that your best bet is to aim off-center if you want to pocket as many balls as possible.
