Have you ever wondered why normal mirror reflections are always along a vertical axis and not a horizontal one? That is, in a normal mirror reflection, the left becomes right and the right becomes left, but the image does not become upside down

Example: The big bang theory (from my understanding of it) says all the matter in the universe was somehow packed into a dot the size of a period. Then it rotated faster and faster (by some unknown energy) until it finally exploded BOOM! sending out debris and matter all directions and ended with the universe as we know it. By scientific law, if an object is spinning one way and releases an object away from it, that object will keep spinning (with no resistance because there is no matter to form friction against said object) the same way.
Why then are some planets and moons spinning opposite ways?
