Grand Fireworks from the Local Super-Bubble
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?
Where are the Sun’s grandparents?
Our Sun’s ancestors are thought to form out of the primordial composition of the early Universe, almost pure hydrogen and helium. How likely are we to observe such stars?
Bridging the gap: asteroid collisions without quantum foam
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?
