Abstract:
We critically investigate some evolutionary aspects of the famous Drake equation, which is usually presented as the central guide for research on extraterrestrial intelligence. It is shown that the Drake equation tacitly relies on unverified assumptions on both the physicochemical history of our galaxy and the properties of advanced intelligent communities. In this manner, the conventional approach fails to take into account various evolutionary processes forming prerequisites for quantification of the Drake equation parameters. The importance of recent results of Lineweaver and collaborators on chemical build-up of inhabitable planets for the search for extraterrestrial intelligence is emphasized. Two important evolutionary effects are briefly discussed, and the resolution of the difficulties within the context of the phase-transition astrobiological models is sketched.

Schwarzschild Radius and Event Horizon
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...
