A mathematical model for evolution and SETI
Origins of Life and Evolution of Biospheres, 2011Darwinian evolution theory may be regarded as a part of SETI theory in that the factor f(l) in the Drake equation represents the fraction of planets suitable for life on which life actually arose. In this paper we firstly provide a statistical generalization of the Drake equation where the factor f(l) is shown to follow the lognormal probability ...

Abstract The distribution of radio bands to various users is a very difficult task internationally. Any signal emitted from outside the Earth will be badly deteriorated by any emission by man—several WARC (World Administrative Radio Conferences), set by ITU (International Telecommunication Union, an agency of the United States), attempt to minimize ...

In October of 2015, news broke of a strange star about 1400 light years from Earth known by the unromantic name KIC 8462852. A small storm in the media brewed as a result of a paper written by the astronomers, led by Yale postdoctoral fellow Tabetha Boyajian, who identified the strange star’s behavior.
