All I've heard about is a single point. Not what is was made of. It would just stand to reason that in order for matter to win you would need more matter than anti-matter. for that to be guaranteed you would have to start out with a single particle of matter that either explodes under it's own pressure or collides with another particle of matter. I'm not a science major of any sort. Just an armchair theorist that is fascinated by science. The reason I suggested a 2 particle collision is based on the attempts of discovering gravitational waves. A single particle will produce the wave effect that they've been searching for but have been unsuccessful. But a collision would produce a different wave. The angle and force of impact would determine the type of wave produced. With that said it may be nearly impossible to determine the wave shape. Yet the "bang" would still appear to come from a single point.
many theories start out with kicking the can. But given enough kicks, it eventually stands upright.
