In 1981, Frank Tipler [4] put forth an argument that extraterrestrial intelligences do not exist, based on the fact that von Neumann probes have not been observed. Given even a moderate rate of replication and the history of the galaxy, such probes should already be common throughout space and thus, we should have already encountered them.
The Berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes. [1] [2] The hypothesis is named after the Berserker series of novels (1963–2005) written by Fred ...
The von Neumann probe [7] is one theoretical example of such a machine. Von Neumann also worked on what he called the universal constructor , a self-replicating machine that would be able to evolve and which he formalized in a cellular automata environment.
Von Neumann's mathematical analysis of the structure of self-replication preceded the discovery of the structure of DNA. [290] Ulam and von Neumann are also generally credited with creating the field of cellular automata, beginning in the 1940s, as a simplified mathematical model of biological systems. [291]
The Hart–Tipler conjecture is the idea that an absence of detectable Von Neumann probes is contrapositive evidence that no intelligent life exists outside of the Solar System. [1] [2] This idea was first proposed in opposition to the Drake equation in a 1975 paper by Michael H. Hart titled "Explanation for the Absence of Extraterrestrials on ...
Von Neumann's System of Self-Replication Automata with the ability to evolve (Figure adapted from Luis Rocha's Lecture Notes at Binghamton University [6]).i) the self-replicating system is composed of several automata plus a separate description (an encoding formalized as a Turing 'tape') of all the automata: Universal Constructor (A), Universal Copier (B), operating system (C), extra ...
Dyson expanded on von Neumann's automata theories and added a biological component to them. Astrochicken, Dyson explained, would be a one-kilogram spacecraft unlike any before it. It would be a creation of the intersection of biology, artificial intelligence and modern microelectronics—a blend of organic and electronic components ...
The von Neumann–Wigner interpretation, also described as "consciousness causes collapse", is an interpretation of quantum mechanics in which consciousness is postulated to be necessary for the completion of the process of quantum measurement.
