From star collisions to mass extinction crashes, gravity is moving everything around in often high-impact events; Imagine a tornado so powerful, it can form a plante or winds sweeping across a planet much like our won, but blowing at 6,000 miles per hour; It's a world in which a single spark or a tiny micrometeoroid can turn a routine mission into a lethal nightmare, while the most dangerous aspects of space travel; They helped build planets through violent collisions and may have seeded Earth with the building blocks for life, but they have also led to mass extinction events, including one that wiped out the dinosaurs.
