BAM! There was a big, fiery collision, a hole in the earth, and a sky full of dust and smoke. And then there were no more dinosaurs. Ancient space rocks float through our cosmos. Usually, they don't do anything, but as soon as they pass through our atmosphere, they are called meteorites. However, unless a meteorite is very large and heavy, we see no more than a small flash in the sky. You make a wish and continue to go about your day. But sometimes, history repeats itself. Are we going in the same direction as the dinosaurs?
