Physicists and philosophers are desperately searching for reality, but aren't getting any warmer. An engineer watches the action and offers comments and answers from his work, The Book of the Universe (view my profile and click on My Web Page).

Logic Isn't All It's Cracked Up To Be
I was browsing the Perimeter Institute’s video
library the other day and came across a talk by Gerard t’Hooft on his new cellular automaton interpretation of quantum mechanics. The theory is in the early stages of development and I understood
little of what he said, but based on his opening remarks, I would bet that the
idea will go nowhere and will simply waste the time of this brilliant Nobel
laureate, one of the most respected physicists in the world.

Dark Matter Isn’t Matter
Dark matter is that mysterious stuff that’s
known to form halos around galaxies and galaxy clusters, but can’t be seen
or—so far—detected, We first met dark matter in this post. It’s energy left in
spacetime after inflation.

The Black Hole Information Paradox...Isn't
Black holes are dead stars that have collapsed
under the gravitational attraction of their own mass. The matter density at the
center of a black hole is extremely high. Some say it is infinite and the
center of a black hole is a singularity. The density is so high that a horizon exists
outside of the black hole where the escape velocity exceeds the speed of light.
Nothing that falls through the horizon can escape, even light. Thus, a black
hole is black because nothing inside can
be seen from outside the horizon.

Yes, We Do Need A New Paradigm
Sean Carroll’s recent blog post is typical of the arrogant
physicist confronting questions that he has no idea how to answer but is
absolutely certain that no one but a physicist like himself could possibly find
the answers. Musing about the origin of life, the origin of the universe, and
the origin of consciousness, he says,

Spin, Statistics, and Forces
While the physicists are thinking about the
universe and coming up with nothing, they’re not giving me anything to blog
about, so I’m going to make good on a promise I made in this post. I’m going to show how the
law of spin and statistics is responsible for three of the four basic
forces—gravity, electromagnetism, and the weak force.

Another Negative Positive Result
A report
on the arXiv describes an experiment that searched for “chameleon fields,” a
modified gravity theory that seeks to explain dark energy without a
cosmological constant. The negative result rules out these fields in a large part
of the parameter space, but not all of it.
In our model, dark energy is a true
cosmological constant, as I explained here,
so for us this result is positive and expected.

News of Interest
In terms of new ideas, things have been pretty
dull in the physics community lately. However, there have been a few negative
experimental results that are bad news for some old ideas and favorable news
for the model I’m describing in this blog.

Whaddaya Mean, It's Not New???
As I explained here,
dark matter in the universe is a remnant of inflation. At the end of the
inflationary period, the universe is left in an oscillating state. These
oscillations can be viewed as particles, or inflaton bosons, the inflaton being
the scalar field that drives inflation. These oscillations decay to form matter
particles, the stuff we’re made of.

Sorry, No Supersymmetry
An Economist article asserts
that the main search target for the upgraded Large Hadron Collider, due to
start up in a couple of months, will be supersymmetric particles, heavier
partners of the standard model particles that have so far never been seen. Supersymmetry is vital to string theory and to
other theories aimed at solving standard model anomalies. Since no evidence of
it was seen in the LHC’s first run, many physicists feel that it has already
been falsified, but many others still think it will be found in the next,
higher-power, run.
In the spacetime model I’m telling you about in this blog, there’s
not even a hint of supersymmetry, so I feel confident in predicting that it
doesn’t exist and won’t be found by the LHC or any future collider.

Paul Steinhardt's New Inflation Theory--Better Than Most, But Still Wrong
On Scientific American’s blog Cross-Check, John
Horgan shares an interview with superstar physicist
Paul Steinhardt of Princeton University on the subject of cosmic inflation, the
period of rapid expansion of the universe immediately following the big bang.
In “Physicist Paul Steinhardt Slams Inflation, Cosmic Theory He Helped Conceive,”
Horgan quotes Steinhardt’s explanation for his change of heart and on the
cyclic model he’s developed to replace the current leading models. He
says,
The
cyclic model emerged when my collaborators and I asked the question: is there
any way of explaining the smoothness and flatness of the universe and small
ripples in density without inflation?
The answer was yes: the key is to have a universe in which the big bang
is replaced by a big bounce. In this
picture, the present period of expansion and cooling is preceded before the
bounce by an epoch of contraction, and the important events that shape the
large-scale structure of the universe (smoothing, flattening and generating
fluctuations) occur before the bounce during a period of slow contraction. There is no high-energy inflation phase –
the universe goes straight from the bounce into a period of slow expansion and
cooling. Inflation is not needed to
smooth and flatten the universe.
Consequently, there is no multiverse. The bounces can repeat at regular
intervals resulting in a cyclic universe.
In some versions, the theory is geodesically complete (existing
infinitely into the past), unlike inflation, which requires a beginning and
special initial conditions.
The remarkable thing about Steinhardt’s cyclic
theory is that it is actually correct in its gross outline. As we saw here, what actually happens is a
contraction in the size of the universe that is simultaneous with a rapid
inflation in the number of spacetime points. This is followed by a phase
transition to the period of slow expansion and cooling that Steinhardt
mentions. So he’s right about the contraction and subsequent expansion, but
he’s wrong when he asserts that there’s no high-energy inflation phase. He
doesn’t know about our spacetime model with its discrete points.
I once
tried to tell Dr. Steinhardt about the correct theory, but I got no response.
Physicists develop the ability to smell correspondence from nonphysicists
trying to help them do their jobs, and it goes directly into the trash. Such is
life.

Neutrinos Are Serious Physics
I want to continue developing our spacetime model in
some of its more sophisticated aspects. We need to know about left- and
right-handed particles and why there are no right-handed neutrinos. We’ll show
that when you have the correct spacetime model, these esoteric subjects aren’t
as intimidating as they’re sometimes made to seem.
Win Some, Lose Some
A couple of new takes on dark matter showed up
this week. One is completely wrong and the other is exactly right in concept if
not in the model proposed to explain the concept.
In Physical Review Letters, a group of British
and Italian physicists has published their conclusion that dark energy is
increasing as it feeds off dark matter. As we saw here, dark energy is the
proliferation of spacetime points by self-reproduction. It drives inflation,
ultimately leaving spacetime in a state of coherent oscillation. The
oscillation energy is dark matter, some of which decays to form luminous
ordinary matter. So these scientists have it exactly backwards, Dark matter
comes from dark energy; it doesn’t decay to dark energy.
On the arXiv, P.Q. Hung and K.J. Ludwick have
come out with a model that has the inflaton (the
field that drives inflation, which we know is dark energy) decaying to dark
matter (correct), a proportion of which decays to luminous matter (correct).
Their mathematical analysis is based on something called the luminogenesis
model, which isn’t a very widely accepted model. I don’t understand the
mathematics, but it looks way too complicated to be correct. However, it’s
remarkable that they have the basic interaction right. Unfortunately, their
fellow physicists will probably ignore it.

Still Not Getting Warmer
At Not Even Wrong, Peter Woit answers the
question, “Are there any plausible alternatives to string/M-theory as a
fundamental theory of physics?” with a resounding “No!” Lee Smolin begs to
differ, commenting that “There is a whole generation of brilliant young
theorists working on alternatives to string theory you should meet.”
Readers of this blog know what spacetime and
matter are made of, and can be pretty confident that all of that young brain
power is barking up the wrong trees. Wish I could help.

Evil says, "I'm possible, therefore I am."
The New Scientist article has Don Page pointing out that this [the many worlds interpretation]
explains the problem of evil. God likes the idea of everything possible
happening all the time so much he’d rather not be bothered to stop bad things
from happening:
“God has values,” he says. “He wants us to enjoy life, but he also
wants to create an elegant universe.” To God the importance of elegance comes
before that of suffering, which, Page infers, is why bad things happen. “God
won’t collapse the wave function to cure people of cancer, or prevent
earthquakes or whatever, because that would make the universe much more inelegant.”
Remarkably,
this is very close to the truth. The glaring problem with it, however, is
Page’s attribution of human-like qualities to God. As we saw here, God is the atemporal aspect
of existence. It is a thought thinking itself. It simply is. It doesn’t like or
want. In observing itself it sees one world of the many possible worlds, and it
sees everything in that world that is possible, thereby creating it. This is
not because it wants to create this kind of world, but simply because it is
existence, the creator of everything possible. We see some things as evil and
some as good, but to God everything simply is. A fundamental tenet of quantum
mechanics is that if something is possible, there is a nonzero probability that
it will be observed. That’s exactly what you’d expect in a universe that
consists of existence observing itself.
Many Worlds, Yet Again
On his blog, Not Even Wrong, Peter Woit reports that the many worlds interpretation of quantum mechanics is getting favorable press again. We dealt with this interpretation here, showing that the many worlds form a population of possible worlds from which, in true quantum mechanical fashion, only one is chosen as atemporal existence observes itself. The many worlds interpretation proves that you can't do accurate physics if you ignore metaphysics.
