Inflationary Theory... A Warped Speculation

The article that's linked in the title talks about how Alan Guth recently held-up a picture of a monkey to portray Neil Turok and what he thought of his cyclic cosmology. Well, Neil Turok can take heart in knowing that there is theoretical support that indicates that the so-called "evidence for inflationary theory" can just as easily mean something that doesn't require band-aids to big bang theory, like inflationary theory, in order to account for the flatness and horizon problems, but especially the magnetic monopole problem... i.e., observational inconsistencies. When you project backwards to the point that extraordinarily rapid expansion becomes necessary, then the most obvious solution to the problem without inflation is simply that the universe had certain volume when the big bang occurred, and... duh'.

Well, "lo.and.behold" that's exactly where we find - "RE-Heating and Thermalization"... surprise... surprise. Could it be that we were in such a big hurry to get to a **pre-assumed** cosmic singularity that we did not pay attention to what projecting the physics backwards was telling us?... I think so...

The actual mechanism that is behind inflation is not even known, but the theory is designed to make predictions that can be matched to the observational data, so it's success at accomplishing this has enabled inflationary theory to become a part of the standard hot big bang cosmology in spite of its many known flaws, and even though it has only been partially justified. The hypothetical particle or field thought to be responsible for inflation is now called the "inflaton"... uh-huh, prove it.

Since all attempts at grand unification have failed, it is now assumed that inflation will be included in a supersymmetric theory, (like string theory), or maybe a supersymmetric grand unified theory, because they can't handle the most apparent implication for a pre-existing time asymmetry, I guess. The standard interpretation is that thermodynamic arrow of time necessarily requires low entropy initial conditions, which John Page pointed-out would be extremely improbable. Rather than solving this problem, the inflation theory further aggravates it because the reheating or thermalization at the end of the inflation era, necessarily increases entropy, meaning that the initial state of the universe had to be even more orderly than in other Big Bang theories that don't have an inflationary phase.

As I noted a couple of posts ago, Lawrence Krauss pointed out that the amplitude of the quadrupole moment of the CMBR is unexpectedly low, and the other low multipoles are observed to be preferentially aligned with the ecliptic plane. This is a signature of what is known as, "non-Gaussianity", which contradicts the simplest models of inflation, requiring more bandaids and cream.

If the microwave background at the multipoles is correlated with the geometry and direction of motion of the solar system, and the incoherence manifests via octopole and quadrupole components in a closed and bounded universe, then there should be a center of gravity at the center of the visible universe that correlates to the ecliptic.

So maybe we're not exactly the "center" of the universe as Krauss thought, rather we're on a centrally preferred "plane" along with a lot of other similarly evolved galaxies, which, with very high probability, will include similarly developed environments and carbon based life, per this Goldilocks Enigma...

Im not a scientist but I've always had trouble visualising "inflation theory". I do not understand how a vaccum so large can be created so quickly, seemingly faster than the speed of light.

Surely to create an instant vaccum, the mechanic of such an event would require information or matter with some sort of mass to travel faster than the speed of light.

Im probably missing something and Im sure inflation proponents have an answer for this which gives it some sort of physics legality.

Anyways, interesting website. I really agree with your ideas about the "anthropic principle".

Thanks, I'm glad that you find merrit.

Inflation doesn't violate special relativity because no information is carried between any two points faster than light speed when "space" expands.

The real question is whether the hypothesis is justified and necessary to the preferred theory, and this is not the case when a causally connected universe has pre-existing volume when we have a big bang, because all of the problems that inflationary theory was invented to resolve are already covered without need of the extra baggage to Big Bang theory.

Inflationary theory was necessitated by the descrepancies that arrise from a pre-existing assumption that a cosmic singularity is necessary for a big bang to occur, but that isn't what the backwards-projections most apparently indicate happened, so it isn't if there wasn't... in other words.
