AND NOW FOR SOMETHING COMPLETELY DIFFERENT.


This post is not humorous in any way, but feel free to find it humorous if you like.
My cousin asked me why the universe is here if I didn't believe in the "Big-Bang Big-Crunch" theory of cosmology, so I wrote the following back to him:

I've only been working on my cosmology for a year or so, so bear with me.  It takes a little bit to get going.


I'm partial to a self-invented version of the Chaotic Inflationary hypothesis.  It allows for (or perhaps requires) a multiverse, and works like this:  The universe as we know it consists essentially of information, or, if you prefer, a series of "x is the case" or "x is not the case" bits of information.  Basically binary, relying on what may simply be a brute fact "There is something."  There seems to be no purpose to the universe, and I don't think we have any evidence to assert that there must be a reason for its existence, so we'll have to settle for "It is the case that the universe exists." for now.

In order to have causality, happenings, and time, we need "if-then" states of affairs.  From a relatively homogenous chaos of nonsensical pieces of information, which generate spontaneously (and on this point I may simply need to bite the bullet and say it is a brute fact that nowhere is there true nothingness, but because it is the case that something exists, wherever there might be true nothingness, there is instead some bit of information, which may or may not relate to anything else.)  At some point a piece of information generated which would have contained the statement "if x is the case, then y is the case".  There happened to be at that time a piece of information "if there would otherwise be nothing here, there is x."

Since the state of affairs known as "the universe", which is essentially the set of all states of affairs (think Wittgenstein's "The world is all that is the case."), contained both the information "x is the case" and the information "if x is the case then y is also the case", the universe then also included the information "y".  There could be many bits of information also that said "if x is the case, and y is not the case, then z is the case." In that case, z would never exist in the universe, because x would never occur without y also occurring. To get away from the letters, there may be a piece of information saying "If it is true that there are triangular things, and it is not true that triangular things can only have angles which add up to 180 degrees, then there can be square triangles."  However, we do have a state of affairs in which triangles can only have angles which add up to 180 degrees, so we never have square triangles.

From this generated a set of comprehensive and co-dependent logical laws, though this does not mean that they are the only possible logical laws, and I grant that some other 'verse which has arisen from the chaos may rely on completely different laws.

Those bits of information which best copy themselves, or are frequent byproducts of commonly occurring "if-then" interactions are the bits of information there are the most of.  The Big Bang may be the result of a state of affairs in which the right bit of information was generated (and it may be a very complicated bit..."if a state of affairs in which a, b, c, and d are the case exists, then it will be the case that bits of information with properties p, q, and s will exist." and if a bit existed that said "If there is any bit of information with properties p,q, and s, then for every bit of information with properties p, q, and s, there will be 100 bits of information with property r").  Or, on a different note, "if the universe is such that a bit with property t generated in place x, and property t made that bit change its location properties in order to be nearer or farther from another bit of information with property t, then that bit also acquires the property of "moving at speed m" "moving in direction h" and "being in spatial location___(wherever it is as it moves)".  And hence, Physics!

A quark is one of the smallest, most basic subatomic particles we know of, and it comes in at least 6 "flavors".  Up quarks and down quarks are all that make up protons and neutrons, with 2 up and a down making protons, and 1 up quark and 2 down quarks making neutrons.  Though it may be an oversimplification, let's say that an up quark is a bit of information with the properties "If this bit is within .0002 picometers of a bit of information with properties [whatever makes a down quark a down quark] and another bit with the same properties as itself, that set of properties creates a state of affairs with the properties [whatever makes a proton a proton]. There is fact about the universe, which we call the "strong nuclear force" that says that when objects (I'm going to call the information bits "objects" now because it's more intuitive, but they are still, essentially, collections of properties, or "if-then" information bits) with the properties [protons] and the properties [neutrons] are within a certain distance from each other, they gain a new property, which is "only able to be separated by x amount of energy".  So they stick together and, because one of the properties of protons is having an electrical charge of +1 (or, "if object p has the properties [proton], it will attract all objects with property [attracted by {proton}] and repel all objects with property [repelled by {proton}]") the object created by the sticking together of the protons and neutron will have a positive electrical charge equal to the number of protons the object contains.

This is the root of chemistry. Chemistry is the root of biology. Biology is the root of Neurology. Neurology is the root of Psychology. Psychology allows for Philosophy, and here I am today trying to bore you to death with my Cosmology.

Based on what I've read, the properties of the universe are such that eventually they will either become inert, that is, run out of objects with properties that allow for "work" to be done (energy) as they continue to drift away from each other, or there is some as-yet-unknown property of the universe which, when some state of affairs is reached, will cause something else entirely to happen.  Since we have, and can have, no evidence of this extra property, Occam's Razor tells us to not complicate our theories with extraneous hypotheses which are not required to explain what we observe.
