Talk:Self-replication

message: Noticed this point in the article - the section that talks about an 'empty program being self-replicating'.
Seems to me to be a dubious statement. Nothing is 'done', so no replication can really be said to have taken place. Yes, it's a very clever idea, but I'm fairly certain that the idea of 'replication' requires some interaction between a thing and its environment; nothingness does not create nothingness - it simply continues being nothingness, and nothing happens.
:Well, the "empty program" example is self-replicating IMO in that you need that initial empty file in order to get the compiler to create another empty file. The key requirement is that compiling it should result in another copy of itself, though, so I don't think scripting languages are an appropriate example. And the bit about a "region of empty space" being self-replicating is right out, since regions of empty space don't replicate at all. I'll rewrite the paragraph and see how it goes.

This is certainly not true.  For example, see , which is a post from year 2000 referring to someone else having earlier observed the same thing.  But the observation that an empty program is syntactically correct in many languages, and that it can stand as a trivial example of a self-reproducing program, is quite obvious, and so was probably noticed decades ago.  
I have removed the reference to Jonathan Finn. -- Dominus
=== By which a thing may act? ===
The very first sentence of this entry leaves me confused.  
"Self-replication is the process by which a thing may act, and thereby make a copy of itself."  There are a whole bunch of ways in which this could be read, but I don't think any of them are accurate.  Gruber76 04:38, 13 April 2007 (UTC)

message: I would argue that one can look to programs like the Apple Worm for a fanciful example of a genome only life form.  In the first section of the Self-replication article, it is said:
**"However, the simplest possible case is that only a genome exists. Without some specification of the self-reproducing steps, a genome-only system is probably better characterized as something like a crystal."
Examples like the Apple Worm negate this contention.  William R. Buckley (talk) 03:24, 17 April 2009 (UTC)

message: I take issue with the inclusion of reference to standing waves (like that in the top-most figure) as being self-replicators.  It is my contention that construction is a critical act of self-replication, and standing waves construct nothing.  William R. Buckley (talk) 01:04, 26 February 2011 (UTC)
replies: text: Thank you for your comment. I think the definition of self-replication should be reconsidered. A standing wave replicates its structure by copying its information to the nearest neighbour, if it is given the same amount of the energy and the resource it consumes. A DNA replicates its structure using the energy from the sun and the resource from the earth, but nothing is left after the end of life, except its trace. CES1596 (talk) 14:03, 27 February 2011 (UTC)

message: I will be happy to discuss in detail the removal mentioned in the section name.  In point of fact, von Neumann never made the claim in any of his papers that self-replicators required universal construction, a position that has been confirmed by later researchers.  What von Neumann did claim is that some constructors can construct any passive configurations (hence, some constructors cannot construct ANY passive configuration), and these he called universal constructors.

message: Astronomers have reliably recorded the fact of an increase in the volume of space in the vacuum of space from an infinitely large number of epicenters. This gain is translated into a mathematical expression called the Linear Hubble Constant: 2.197 * 10 ^ -18 per second. But the universe is not a linear object, but a volumetric object, so it would be correct to use the Hubble Volume Constant: 6.591 * 10 ^ -18 per second.
Physicists have reliably established the fact that protons, atomic nuclei and electrons are the epicenters of electrostatics and magnetic dipoles. Neutrons are electrostatically neutral, but still magnetic dipoles.
Electrostatics and magnetism are loose matter. It is obvious that the structure of electrostatics and magnetism is built from the flows of their elementary units, elementary vortices.
Presumably, elementary vortices of electrostatics, rotating clockwise, emanating from their source (proton, nucleus of an atom), and counter-complementary elementary vortices of electrostatics, rotating counterclockwise relative to the vector of their motion, flowing to their drain (proton, nucleus of an atom), characterize electrostatics of the action sign + -.
Presumably, elementary vortices of magnetism rotating clockwise, emanating from the south magnetic pole of their source, and counterclockwise complementary elementary vortices of magnetism rotating counterclockwise relative to their vector of motion, flowing to their drain (young magnetic pole), characterize the magnetism of the sign of the action South -North.
An electrostatically neutral neutron, probably in equal proportions, emits outward elemental vortices of electrostatics rotating clockwise and rotating counterclockwise. Accordingly, the same model of equal proportion for elementary vortices of magnetism flowing to the neutron.
Probably, the chaos of streams of elementary vortices of loose matter of electrostatics and magnetism, flowing from their sources and flowing to their drains, make up the loose matter of the vacuum of space.
Since the volume of space in the vacuum of space is constantly increasing, it must be recognized that protons, atomic nuclei, electrons and neutrons are the epicenters of the birth of new elementary vortices of electrostatics and magnetism. And a very small part of the space volume of chaos of flows of elementary vortices of electrostatics and vacuum magnetism self-focusing and compacting dense matter of new atomic mass units in the form of new neutrons close to the already existing neutrons, protons, nuclei of atoms (and electrons; or electrons are constantly moving too fast and therefore they do not can be the epicenters of the creation of new antineutrons?).
From this model of the universe, it follows that in equal proportions of the Hubble Volume Constant, the volume of space of non-dense matter of vacuum and the mass of dense matter matter increase. And therefore, on average in the universe, for 1 atomic mass unit of dense matter of matter, in all epochs there are about 4-6 cubic meters of loose matter of the vacuum of space.
Consequently, the universe has always been and will always exist, equally proportionally increasing in the volume of space of the vacuum of space and the mass of matter.
