The problem with the experiment is worse than than you think. AZSquib has audited the report and discovered that standard uncalibrated Ethernet timers were effectively used to timestamp the neutrino events. An impressive master clock was present but used to no effect, only to hide the long term drift.

The Einstein tensor is taken to be second rank for no other reason but convention.
Careful consideration makes it out to be fourth rank covariant, so that it is a "geometric object" with no artificial entanglement with the metric added in after the natural derivation. The requirement that a tensor be drawable, and that problems can be worked correctly on this drawing independent of changes in scale and sparseness, is one of the many corollary forms of general covariance. Artificial entanglement with the metric - by arbitrarily changing the tensor rank from fourth to second - breaks this requirement of general covariance. Breaking general covariance implies a favored set of units of measurement, where second rank and fourth rank tensors can have identical implications.
And consider that the Einstein tensor has units of measurement of L^-4; this is inherently fourth rank covariant. To derive the Einstein tensor from the metric, two exterior derivatives are taken (with a dual taken in between); these transform the result from the original second rank covariant to fourth rank covariant.
Take another exterior derivative on the Einstein tensor to arrive at the Bianchi identity. The terms of this identity correspond to conservation laws in mechanics.

But no term at all for this is included in the analysis. Long nano fibers would have an unfocused influence on the measurements.
"... why [do] you think the mathematical model is an "embarrassment" or are you simply trolling?"
The cosmological constant and many other representations of dark energy are ruled out by the Bianchi identities that apply. This becomes plain when when the proper tensor rank is used for the spacetime entities invoked. The cosmological constant is an artifact of using a second rank tensor to represent the Einstein tensor, and a simple divergence operation to show conservation, instead of using the fourth rank tensor and exterior derivative operation that satisfy the criterion of general covariance. The Bianchi identities translate to the conservation laws in the context of mechanics, but in geometry they are theorems which follow when the metric exists.
"... phenomenology
General relativity is not a mere metaphor, as epicycles were.

Newton's formula for gravity does agree with this possibility that inheres in the Einstein tensor. It is also interesting that a simple acceleration of expansion gives supernovae that are closer and brighter at a given redshift.
"Yeah, yeah, tachyons with negative mass."
I should have written negative momentum, which is a better translation into mechanics of the possibilities allowed by the Einstein tensor. There is no principle in geometry which disallows this feature of the Einstein tensor. The Bianchi identities conserve superluminal momentum in that same superluminal direction. The identities even allow superluminal dilation horizons.
Spacial dilation causes divergent spacial curvature, which progressively weakens the intensity of light as it travels. This agrees with the phenomenon.
But a non conserved version of dark energy is contrary to the Bianchi identities.
Dark energy represents an empirical set of evidence as well as a mathematical model. The empirical evidence could yet be interpreted in the context of the existence of accumulating carbon dust, and the evolution over history of the supernovae concerned - their increasing content of metals and their increasing spin as time progresses.
The mathematical model rates as an embarrassment from the perspective of my criticism of fundamental physics. What withstands criticism is a possible background of conserved negative mass, together with a possible background of negative tachyonic mass, which is conserved in its direction of propagation.
I have already written on the contradictions involved in electromagnetic radiation from a superluminal source. The best conclusion is that superluminal charges themselves should be defined as unobservable.
For this the kudos go to Scott Gray, publishing as AZSquib - see http://blog.vixra.org/2011/09/19/can-neutrinos-be-superluminal/#comment-11088 . It is regrettable that, as quickly as the problem was identified, it was not found sooner, before public attention was expended on the reported results. As discovered by AZSquib, standard issue Ethernet quartz crystals and circuits were used to timestamp event records. These were never calibrated, and their possible variation was not included in the
I have a tutorial topic list (Hacking Physics Tutorial) entailing about about 24 sessions that includes six sessions on solving general relativity by referencing scaled and sparse diagrams. High school graduates with a mastery of precalculus are not deterred by the pace of this, even when it is three am at "the bitter end". When academic physics is thoroughly reformed, this will not seem so radical.

I watched the talk by Professor Ha-Joon Chang on Book TV just now. I thought that I knew about market failure theory, but he threatens to break the entire theory of a free market in his book, "23 Things They Don't Tell You About Capitalism". He points out that the classical economist, Richardo, wrote in the 19th century that the accumulation of wealth by the landed gentry was insufficient for economic growth. A government policy on investment was an apparent nece
You are substantially correct. Antimatter attracts light, and it also follows the same geodesic curve as matter would - there is evidence of this last from study of antineutrons. General relativity does have within itself room for the concept of regions of negative mass (but this is not what antimatter is made of). These regions would repel light, matter and other regions, but they would follow the same geodesic curve as matter would.
Dark matter is some kind of matter in motion. This is so because some properties of the phenomenon are inferred from the gravitational effect and then from the rate of condensation or equilibrium size and mass. The inferences are founded on theory or principle - those of general relativity and thermodynamics.
But all inferences are founded on some set of principles or theories. And, contrary to the trend of anti-intellectual rebellion in physics departments and elsewhere, general relativity is actually founded on theorems with an extremely economical premise - the existence of the metric. (The theorems are applications of the Bianchi identity.)
These considerations are sufficient to mark the existence of dark matter as a very elegant empirical result.
Your impulse to pronounce with the long sound is entirely legitimate; it would be especially so in west Michigan or Wisconsin. Remember that Linus himself when speaking his native language emits "LEENUKES" (the long sounds).
I actually sat down recently to calculate the dimensions of a Kaluza-Klein charge that emulates the charge and mass of an electron. My calculator was a page of penciled equations plus the Unix command line facility, units. I included in this calculation the effects of the internal polarization that I wrote on earlier this year. In doing so, I realized that the push me pull you polarization of a Kaluza-Klein charge is an amplifier of the background Kaluza-Klein field that the charge is subject
An advanced or efficient civilization most likely makes for a more closely balanced and diverse legislature. This will increase the power of the executive of the government. The President has the remarkable powers of veto and of authorizing debt, not to mention the ability to unleash the Department of Justice. His refusal to make use of these powers marks him as a genuine conservative.
I am going to try to confirm that the new Linux kernel for Fedora 15 has eliminated my crash on resume for Gnome 3 and the T115D Satellite portable.

The relativity argument by Max Planck does fix the value of five constants of nature as determined by arbitrary human choice. Namely, physicists must decide on the magnitude of five units of measurement before they can do any measurements concerning those five constants. And it is even possible to chose units of measurement by specifying values for the five constants. (The relativistic invariant here is the physical magnitude of the constants.)
It only remains to argue then, that the speed of light is a constant for all qualified observers in their local vacuum. This argument depends on considering the contradictions in the definition of the electromagnetic potential that can arise when a central charge is reversed in its direction of travel. The full range of these contradictions are only resolved when changes in potential are required to propagate at a particular local speed that exceeds any possible speed of the central charge. (Academic literature not withstanding, superluminal charges make no sense.)
Anyone can make an omelet with eggs. The trick is to make one with none.
