"Study finds possible alternative explanation for dark energy" | Phys.Org
Physicists don't seem to be buying what Kipreos is selling.A new study by University of Georgia professor Edward Kipreos suggests that changes in how people think about time dilation—the slowing of time predicted by Albert Einstein—can provide an alternate explanation of dark energy.

The new paper makes the case that instead of being reciprocal, time dilation in response to movement is directional, with only the moving object undergoing time dilation.

"Pay to Play" | One Universe at a TimeAs you can tell, this isn’t a modest proposal at all, but (to use the unkind phrasing usually attributed to unkind physicist Wolfgang Pauli) it isn’t even wrong. His modification to the laws of physics are too large, with implications he avoids by not dealing with them. Instead, he focuses on a few small aspects of relativity: the loss of simultaneity between moving frames of reference and the time-dilation effect measured by two observers moving rapidly with respect to each other. These are connected phenomena, but they are both consequences of the larger theory, which is not only well-tested in its own right, but the foundation of the two best-tested theories we have: general relativity and quantum electrodynamics.

There’s new research being touted in the press about a possible solution to the dark energy mystery. The results, published in the peer-reviewed journal PLOS ONE argues that a radical modification of relativity can account for dark energy. The work is so abysmally awful that it makes you wonder just how such a paper got accepted for publication.
The central claim of the paper is that our understanding special relativity is wrong. Instead of all motion being relative, which causes time dilation between objects and means that there is no absolute cosmic time frame, the author argues that all motion is measured relative to some absolute time frame. This means that motion can be measured relative to this absolute frame, and things like time dilation only occurs relative to that absolute cosmic frame.
Those familiar with relativity might point out that we’ve long known that the speed of light is a universal constant in all frames of reference, and experiments such as the Michelson-Morley experiment showed that there is no absolute reference frame. Even things like GPS satellites show that relativity works, so how does one argue that there’s an absolute reference frame? As the author points out, to agree with observation, you just have to assume that the absolute frame of the universe is centered on the Earth and rotating with it.
You heard that right. The author argues that in terms of this cosmic reference frame, the Earth doesn’t move.
