From hoverboards to flying cars to cloud cities, anti-gravity is a staple of science fiction and our dream of a less Earth-bound future. But in the real universe gravity appears to be a purely attractive force. Feels like its main MO is keeping us stuck to the surface of this lonely rock. But maybe if we science hard enough we can remove the fiction from science fiction. For the sake of our flying cars we should at least try. And for many years, physicists have wondered whether a certain well-known exotic material may experience gravitational repulsion from the Earth. That material is antimatter, and physicists at CERN have just completed a very long and very difficult experiment to answer a seemingly simple question: does antimatter fall down, or does it fall up?

150 million ago, Southeastern Colorado was a tropical climate with dinosaurs roaming the land. The Apatosaurus and Allosaurus have left remnants of their presence in the ground with over 1900 footprints that have been preserved in the rock. The location of the tracks was previously a muddy bank of a lake during the Jurassic era. Today, the Comanche National Grassland hosts North America’s largest dinosaur track site, which are found along the shores of the Purgatoire river, forming over 130 trackways.
