Galactic Punctuated Equilibrium: How to Undermine Carter's Anthropic Argument in Astrobiology
Milan M. Cirkovic, Branislav Vukotic, Ivana Dragicevic
We investigate a new strategy which can defeat the (in)famous Carter's "anthropic" argument against extraterrestrial life and intelligence. In contrast to those already considered…
Chaotic Transport and Chronology of Complex Asteroid Families
Bojan Novakovic, Kleomenis Tsiganis, Zoran Knezevic
We present a transport model that describes the orbital diffusion of asteroids in chaotic regions of the 3-D space of proper elements. Our goal is to use a simple random-walk model…
Fermi's Paradox - The Last Challenge for Copernicanism?
Milan M. Cirkovic
We review Fermi's paradox (or the "Great Silence" problem), not only arguably the oldest and crucial problem for the Search for ExtraTerrestrial Intelligence (SETI), but also a con…
Planet formation bursts at the borders of the dead zone in 2D numerical simulations of circumstellar disks
W. Lyra, A. Johansen, A. Zsom +2
As accretion in protoplanetary disks is enabled by turbulent viscosity, the border between active and inactive (dead) zones constitutes a location where there is an abrupt change i…
