On The Timescale Forcing in Astrobiology

Abstract: We investigate the effects of correlated global regulation
mechanisms, especially Galactic gamma-ray bursts (GRBs), on the temporal
distribution of hypothetical inhabited planets, using simple Monte Carlo
numerical experiments. Starting with recently obtained models of planetary
ages in the Galactic Habitable Zone (GHZ), we obtain that the times required
for biological evolution on habitable planets of the Milky Way are highly
correlated. These results run contrary to the famous anti-SETI anthropic
argument of Carter, and give tentative support to the ongoing and future
SETI observation projects.
