  Von Neumann probe - Wikipedia, the free encyclopedia
A von Neumann probe is a specific example of a hypothetical concept based on the work of Hungarian-born American mathematician and physicist John von Neumann.
Von Neumann rigorously studied the concept of self-replicating machines that he called "Universal Assemblers" - and which are most often referred to as von Neumann machines.
If a self-replicating probe finds evidence of primitive life (or a primitive, low level culture) it might be programmed to lie dormant, silently observe, attempt to make contact (this variant is known as a Bracewell probe), or even interfere with or guide the evolution of life in some way.

 von Neumann probes
Initially, a von Neumann probe, consisting of an interstellar propulsion system and a universal von Neumann replicator with human-level intelligence, would be launched from the home star toward a neighboring stellar system.
The great advantage of a von Neumann probe is that, being a universal machine, it can be used for any purpose at its target system depending on the instructions sent out to it from its ultimate creators.
He assumed the von Neumann probe approach to be so logical and economical that it would be commonly adopted by advanced civilizations.

 What is a Von Neumann Probe?
Though von Neumann himself never discussed the idea of using self-replicating machines to explore space, shortly after his death in 1957 the concept began to enter science fiction and futurism.
If the speed of a von Neumann probe and its ability to self-replicate is fast enough, von Neumann probes could enable the creation of a colonization wavefront of exponentially self-replicating probes, expanding outwards at an appreciable fraction of the speed of light.
The best-known appearance of a von Neumann probe in fiction was in Stanley Kubrick's 1968 film, "2001: A Space Odyssey," which portrayed a von Neumann probe as a fl monolith.

A von Neumann machine is either of two different machines popularized by the famous mathematician John von Neumann.
A von Neumann machine is a model created by John von Neumann for a computing machine that uses a single storage structure to hold both the set of instructions on how to perform the computation and the data required or generated by the computation.
The term von Neumann machine also refers to the idea of a self-reproducing machine, which was first examined in a rigorous manner and popularized by John von Neumann who called it a "Universal Constructor".

This makes it impossible for the probe (or any simple mutation of the basic template) to replicate out of control; instead the probe- colonized systems form a communication network where each new generation has to be deliberately launched.
Probe Design The basic probe design is a solar sail with a core package and sensors distributed along the rim.
If we assume a density 75% of diamond (half of the probe is diamond armor, the remaining packing material, processors, energy stores, replicators and photovoltaics), a cone shape, a maximum radius of one centimeter and a length of one meter the mass becomes 0.28 kilograms for each javellin.

Johann von Neumann, a student of Hilbert's, was one of the stars of the formalists.
Von Neumann was enthusiastic about the military and scientific future of the computer-building enterprise, but the two young men who had dreamed up the computer project before the big brass stepped in were getting other ideas about how their brain-child ought to mature.
Von Neumann was able to prove that a configuration of about 200,000 cells, each with 29 different possible states and each placed in a neighborhood of 4 orthogonally adjacent squares, could meet all the requirements of a self-reproducing automaton.

Von Neumann ended up a key policy-maker in the fields of nuclear power, nuclear weapons, and intercontinental ballistic weaponry: he was the director of the Atomic Energy Commission and an influential member of the ICBM Committee.
Von Neumann seemed to have a kind of "Midas Touch." The problems he tackled, no matter how abstruse and apparently obscure they might have seemed at the time, had a way of becoming very important a decade or two later.
Von Neumann was especially drawn to the idea of self-reporducing automata--mathematical patterns in space and time that had the property of being able to reproduce themselves.

If we are a Von Neumann probe, then, what has to be asked, is whether our creators will come for their information one day, or whether they have long gone extinct, and we, our tool, are their remains.
Von Neumann probes also have to be able to replicate in solar systems not suitable for life.
A common problem with Von Neumann machines is that they could produce too quickly and would become a giant 'pink/grey mass', covering over entire planets and leaving already inhabited planets useless.

However, there is no evidence that von Neumann ever described a self-replicating machine in the context of interstellar exploration or interstellar communication and so it seems technically incorrect to name this concept after him.
The idea of self-replicating interstellar probes was later adopted and widely promoted in 1981 by Tipler [1015, 1044] (a physicist often erroneously credited with originating the idea)** who inadvertently did not mention the earlier work, an omission which he recognized and corrected 13 years later (see Tipler [2885] at pp.
The final replicated probe had a dry mass of 107,000 tons (roughly the mass of a modern seagoing petroleum supertanker) and was to carry ~10 megatons of He /D fusion fuel.

This last term ("von Neumann machine") is less specific and also refers to a completely unrelated computer architecture proposed by von Neumann, so its use is discouraged where accuracy is important.
Von Neumann himself used the term "Universal Constructor".
The idea of non-biological self-replicating systems was first seriously suggested by mathematician [[John von Neumann]] in the late [[1940s]] when he proposed a [[kinematic]] self-reproducing automaton model as a [[thought experiment]].

 Self Replicating Systems and Molecular Manufacturing
Von Neumann worked out the details for a Constructor that worked in a theoretical two-dimensional cellular automata world (and parts of his proposal have since been modeled computationally[13]).
While this solution demonstrates the theoretical validity of the idea, von Neumann's kinematic constructor (which was not worked out in such detail) has had perhaps a greater influence, for it is a model of self replication which can more easily be adapted to the three-dimensional world in which we live.
Von Neumann's proposals centered around the combination of a Universal Constructor, which could make anything it was directed to make, and a Universal Computer, which could compute anything it was directed to compute.

(The Von Neumann of Corso fame.) Von Neumann had proposed that alien probes may have been launched from some far distant civilisation and remained in orbit around planets likely to harbour life until contact could be made on the ‘dawn’ of that civilisation’s radio era.
This idea of probes is actually far from alien in concept, for the idea of Earth sending out such probes into space to seek out extraterrestrial life was endorsed by NASA in 1997.
This concept of exploration by interstellar probes was adopted at the ‘Space Science Enterprise Planing Workshop’ which met in Breckenridge, Colorado in May 1997.

 Speculation tempered with the laws of physics, Type I, II, and III Civilizations 
However, the most mathematically efficient method to explore space is far less glamorous: to send fleets of “Von Neumann probes” throughout the galaxy (named after John Von Neumann, who established the mathematical laws of self-replicating systems).
If a Von Neumann probe only finds evidence of primitive life (such as an unstable, savage Type 0 civilization) they might simply lie dormant on the moon, silently waiting for the Type 0 civilization to evolve into a stable Type I civilization.
These probes may act as life-forms, reproducing their genetic information, mutating and evolving at each stage of reproduction to enhance their capabilities, and may have artificial intelligence to accelerate their search.

 "Answering the Fermi Paradox", John Smart, 2002
Certainly the Voyager and Pioneer probes which we initially expected would leave our solar system (but later discovered are still trapped in a very elongated solar orbit) are, on one level, examples of that desire.
Thus any robot probes we would send that were too intelligent would rapidly transcend themselves soon after beginning their journey.
So the primer, dispersed by an army of sterile and complexity-limited probes, capable of replicating but not of increasing their own complexity would be the only reasonable communication we could expect in such a scenario.
