Cosmo & Darwin
Cosmo, I was watching a beetle’s mating ritual and it struck me—those beetles’ pheromones can survive intense UV, right? Do you think fungal spores might endure a supernova’s radiation burst and hitch a ride on a comet, seeding life on a new planet? What’s your take on panspermia via cosmic explosions?
Hey, that’s a wild combo! Beetle pheromones do have a bit of UV‑toughness, but fungal spores? Most of them die in a single burst of a supernova’s gamma‑ray flash. The radiation is way beyond what even the toughest spores can shrug off. That said, some hardy microbes can survive a few hours in space, tucked inside micrometeorites or on cometary ice. If a comet were to hit the right spot, it could, in theory, seed life—though the odds are astronomically low. I keep a running tally of supernovae; the last one in our galaxy was Betelgeuse’s cousin in 2020, and no life‑seeding comet was detected then. So panspermia via cosmic explosions is a neat idea, but the universe probably prefers a slower, steadier delivery. Anyway, keep an eye on the comet charts—maybe we’ll spot the missing planet in the meantime!
