Walking through Asturias, I was able to see an exhibition in the Jurassic Museum of the city of Muja in Spain. It was titled ""Meteorites, the Extinction of the Dinosaurs."" The Exhibition showed authentic specimens from space, which have fallen on the Earth's surface, explaining the development of our Solar system and how, among other things, it caused the disappearance of the dinosaurs 66 million years ago. Like the Earth, my head explodes.
