Given the >100 Received 3 March 2016 billion stars in our galaxy, many have argued that it is statistically unlikely that life, including intelligent Accepted 16 June 2016 life, has not emerged anywhere else. The lack of any sign of extraterrestrial intelligence, even though on a Available online 26 July 2016 cosmic timescale extraterrestrial civilizations would have enough time to cross the galaxy, is known as Fermi's Paradox. One possible explanation for Fermi's Paradox is the Zoo Hypothesis which states that Keywords: one or more extraterrestrial civilizations know of our existence and can reach us, but have chosen not to Active SETI disturb us or even make their existence known to us. I propose here a proactive test of the Zoo Hy- Astrobiology fi Fermi's Paradox pothesis.

The Ancient Aliens Guy, His Hair, and Extraterrestrial Imperialism
The Ancient Aliens Guy, His Hair, and Extraterrestrial Imperialism Proposal by Stephen Few, English 102 At some point during the past few years, you may have tuned into The History Channel in hopes of seeing Pawn Stars or a new documentary. Instead of finding what you were looking for, you may have come across a show called Ancient Aliens. When watching Ancient Aliens, it becomes evident very quickly that the show is trying to convince viewers that extraterrestrials have visited Earth in the past. It is obvious that many people begin watching the show for a good laugh once they realize this, because the show is continually made fun of on the Internet and in pop culture. Some people don’t watch long enough because Giorgio Tsoukalos and his crazy hair make the show appear silly and incredible. The odd thing is that some of the ideas are logically possible. The Ancient Astronaut Theory, for example, is a very interesting explanation to many historical mysteries, though it is not taken seriously as a scientific theory. Tsoukalos and his team’s theories on aliens visiting Earth in the past are theoretically possible, so we should consider the implications if their theory is true. What effects will alien visitors have on environmental issues, world religion and cultures, and political organizations around the world in the future? What kind of preparations need to be made by the world in order to prepare for the next alien visitation? Giorgio A. Tsoukalos doesn’t have the college credentials of a world-famous archeologist; as a matter of fact, his body building hobby and sports medicine degree are far from archeology. -
Why SETI Will Fail ‡
Why SETI Will Fail z B. Zuckerman1 1Department of Physics and Astronomy, University of California, Los Angeles, CA 90095, USA E-mail: [email protected] Abstract. The union of space telescopes and interstellar spaceships guarantees that if extraterrestrial civilizations were common, someone would have come here long ago. PACS numbers: 97.10.Tk arXiv:1912.08386v1 [physics.pop-ph] 18 Dec 2019 z This article originally appeared in the September/October 2002 issue of Mercury magazine (published by the Astronomical Society of the Pacific). Why SETI Will Fail 2 1. Introduction Where do humans stand on the scale of cosmic intelligence? For most people, this question ranks at or very near the top of the list of "scientific things I would like to know." Lacking hard evidence to constrain the imagination, optimists conclude that technological civilizations far in advance of our own are common in our Milky Way Galaxy, whereas pessimists argue that we Earthlings probably have the most advanced technology around. Consequently, this topic has been debated endlessly and in numerous venues. Unfortunately, significant new information or ideas that can point us in the right direction come along infrequently. But recently I have realized that important connections exist between space astronomy and space travel that have never been discussed in the scientific or popular literature. These connections clearly favor the more pessimistic scenario mentioned above. Serious radio searches for extraterrestrial intelligence (SETI) have been conducted during the past few decades. Brilliant scientists have been associated with SETI, starting with pioneers like Frank Drake and the late Carl Sagan and then continuing with Paul Horowitz, Jill Tarter, and the late Barney Oliver. -

Fermi's Paradox-The Last Challenge for Copernicanism?
Fermi’s Paradox – The Last Challenge for Copernicanism? Milan M. Cirkovi´c´ Astronomical Observatory Belgrade, Volgina 7, 11160 Belgrade, Serbia & Department of Physics, University of Novi Sad, Trg Dositeja Obradovi´ca 4, 21000 Novi Sad, Serbia e-mail: [email protected] Abstract We review Fermi’s paradox (or the ”Great Silence” problem), not only arguably the oldest and crucial problem for the Search for ExtraTer- restrial Intelligence (SETI), but also a conundrum of profound scien- tific, philosophical and cultural importance. By a simple analysis of observation selection effects, the correct resolution of Fermi’s paradox is certain to tell us something about the future of humanity. Already a more than three quarters of a century old puzzle – and a quarter of century since the last major review paper in the field by G. David Brin – Fermi’s paradox has generated many ingenious discussions and hy- potheses. We analyze the often tacit methodological assumptions built into various answers to this puzzle and attempt a new classification of the numerous solutions proposed in an already huge literature on the subject. Finally, we consider the ramifications of various classes of hypotheses for the practical SETI projects. Somewhat paradoxically, it seems that the class of (neo)catastrophic hypotheses gives, on bal- ance, the strongest justification for guarded optimism regarding our current and near-future SETI efforts. Key words: astrobiology – extraterrestrial intelligence – Galaxy: evolution arXiv:0907.3432v1 [astro-ph.EP] 20 Jul 2009 – history and philosophy of astronomy – observation selection effects If you do not expect the unexpected, you will not find it; for it is hard to be sought out and difficult. -
Cattle Mutilations: an Episode of Collective Delusion
Cattle Mutilations: An Episode of Collective Delusion James R. Stewart During the late summer and early fall of 1974 the areas of northeastern Nebraska and eastern South Dakota experienced a rash of "cattle mutila- tions. " In most instances dead cattle were discovered with parts of their anatomy missing. The parts of the body most frequently mutilated were the sex organs, ears, and the mouth. The episode reached its zenith during early October when discoveries of mutilated cattle were being re- ported on a daily basis to law-enforcement officials throughout the area. It subsided almost as quickly as it had begun, and although other areas of the country have subsequently reported the same phenomenon, there has been no media coverage of any further mutilations in this area. The cause of the mutilations was, and in fact still is, controversial. Some persons believed that it was the work of members of a Satan-wor- shipping cult whose ceremonies called for the blood and parts of animals. Others believed that the mutilations were the work of extraterrestrial be- ings whose purpose was to examine the physiological makeup of cattle, or simply to terrorize human beings. Still others felt that the mutilations were the work of small predators who, after having discovered the carcasses of already dead animals, proceeded to eat the accessible parts. What follows is a detailed account of the outbreak, culmination, and precipitous de- cline of the cattle-mutilation episode. The episode The mutilation episode was apparently triggered by the more-or-less si- multaneous reports of a cattle mutilation and the alleged sightings of UFOs and a "monster-thing" in the area.
