A group at University of Washington, Fardon et al
just posted "Dark Energy from Mass-Varying Neutrinos"
which does not seem to me as far-fetched as other speculation I've seen about cause of DE

they seem to think that some element of their idea is
testable with an accelerator at attainable energies

I recall reading another paper(it may be the same team)and I have something written down on my thoughts. As far as I am able to recall, I concluded that the position of source had a baring on neutrino detection, being that the density of our local field (generated by the Suns radiative photons emmisions, amongst a background density of accelerated expanding vacuum density-within our Milkyway) can determine the speed of neutrino's.

Accumilated Neutrino Mass, and dissapated Neutrino Mass from a 'in-flight' transformation of Where the Neutrino's have come from, and where they are now? I should be commenting on this without actually getting my paperwork out!..but my consensus is now as was then:Past-Present Neutrino flux are constrained by our local bubble within the Milky way, certain neutrino's come from close by, whilst others come from far off place's. Simply put Neutrino's are dependant on how many interactions(phase-interactions) they have been party to, currently it seems there has been three important Phase's of our Universe.

The density of local space may be changed ,Phase Transformed, by the total Neutrino per volume/density.
 


The recent speculation about the cause of dark energy is certainly intriguing. The idea proposed by Fardon et al, that dark energy could be the result of mass-varying neutrinos, is a unique and potentially testable theory. It is refreshing to see a new approach to understanding the mysterious force driving the expansion of the universe.

While other speculations about dark energy have been met with skepticism, the idea of mass-varying neutrinos is not as far-fetched. Neutrinos are known to have mass, and their properties are still not fully understood. This makes them a prime candidate for further investigation into their potential role in dark energy.

The fact that Fardon et al's theory can be tested with an accelerator at attainable energies is also promising. This means that their hypothesis can be put to the test and potentially provide evidence for or against their idea. The ability to test a theory is crucial in the scientific community, and it adds credibility to their speculation.

However, it is important to note that this is still just a speculation and further research and evidence is needed to fully support this theory. As with any new idea, it is important to approach it with a critical and open mind, and to continue to explore other potential explanations for dark energy.

Overall, the new speculation about the cause of dark energy is a thought-provoking and exciting development in the field of astrophysics. It will be interesting to see how this theory develops and if it can provide a deeper understanding of the mysterious force driving the expansion of our universe.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
