Would older, elliptical galaxy be less hospitable to life? Or would it not matter? Would there be more GRB's and various other conditions that would decrease the likelihood of life? Just curious.
- cjfont 11y agoAccording to the article, supernovas occur more frequently in younger galaxies, and we know these can blow a star's heliosphere away temporarily exposing all its planets to deadly radiation (which it seems has happened to Earth before).
