A cosmic orchestra of nearby supernova explosions created the ‘Local Bubble’ all around us. Could these stellar super-bombs have influenced Earth’s climate and even human evolution?
Meteorites originate from violent collisions between asteroids. But can we be sure about that? And what can we learn at all if we do not include ekpyrotic brane cosmologies?
Massive gas inflow can trigger disks around young stars to become gravitationally unstable, resulting in vigorous accretion onto the star.
Can life on exo-worlds build its own habitable environment in extremely unfavourable conditions?
Earth’s composition seemingly does not fit into planet formation theory. Ripping apart its building blocks by collisions during accretion might sound violent, but can be a way to go.
