Ran across the event that will happen perhaps 5 billion years from now - the collision of Andromeda and our Milky Way galaxy. This event is surely only one of many now occurring in space. So, if constellations are always colliding in a universal space so vast to be almost incomprehensible, then there must be unimaginable numbers of exoplanets, orphan planets, and "shrapnel" from uncountable collisions such as our solar system has experienced. Apparently, a collision with Tiamat and Planet X is a common occurrence. Chaos is the order of the day. Knowing there exists an unknown number of galaxies with so many more solar systems in existence is too much for my feeble mind. Al C.
