The chance is >0, but beyond that it's just speculation--some of it very fancy, but speculation all the same. For example, for awhile there was a theory that mass extinction events were correlated to the solar system's orbit as it passed through the galactic plane. That model, which is now largely rejected (per Wikipdia), predicted periodic relative increases and decreases in event rates across time spans down to sev…

Yes it's one of the most significant existential threats to life on earth. Probably #2 after self-inflicted environmental destruction.
