The Ironic Universe: updated

"Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported."

This dark flow motion together with cosmological electromagnetic anisotropy (or birefringent polarization) together seem to point to some sort of directed universal evolution of even supposed inorganic matter that no sanitized purely mathematical model can account for. It is evidence that no matter how long one attempts to achieve a so-called unified field theory the universe will always present us with some unexpected singularities due to its continuing evolution. We will forever be baffled by the fact that the universe always seems to surprise us.

Here's yet another irony in the news:

"Sunspots are supposedly rooted to the bottom of the belt," says Hathaway. "So the motion of sunspots tells us how fast the belt is moving down there."

He's done that—plotted sunspot speeds vs. time since 1996—and the results don't make sense. "While the top of the conveyor belt has been moving at record-high speed, the bottom seems to be moving at record-low speed. Another contradiction."

Could it be that sunspots are not rooted to the bottom of the Conveyor Belt, after all? "That's one possibility" he notes. "Sunspots could be moving because of dynamo waves or some other phenomenon not directly linked to the belt."

Running away from Einstein

"This 10 million light year-wide ring made up of small galaxies is expanding rapidly like a mini Big Bang. The team believe our neighbouring galaxy, Andromeda, once flew past our own galaxy at close range, creating a sling-shot of several small galaxies.

Dr Hongsheng Zhao, Reader in the School of Physics and Astronomy and co-author of the paper, published in Monthly Notices of the Royal Astronomical Society by Oxford University Press, said: "If Einstein's gravity were correct, our galaxy would never come close enough to Andromeda to scatter anything that fast.""

"Scientists are finding that galaxies can move with each other across huge distances, and against the predictions of basic cosmological models. The reason why could change everything we think we know about the universe."

The fine structure constant has a directional anisotropy.

"And it seems to be supporting this idea that there could be a directionality in the universe, which is very weird indeed," Professor Webb says.

"So the universe may not be isotropic in its laws of physics - one that is the same, statistically, in all directions. But in fact, there could be some direction or preferred direction in the universe where the laws of physics change, but not in the perpendicular direction. In other words, the universe in some sense, has a dipole structure to it.

"In one particular direction, we can look back 12 billion light years and measure electromagnetism when the universe was very young. Putting all the data together, electromagnetism seems to gradually increase the further we look, while towards the opposite direction, it gradually decreases. In other directions in the cosmos, the fine structure constant remains just that - constant. These new very distant measurements have pushed our observations further than has ever been reached before."

K-State study reveals asymmetry in spin directions of galaxies
The patterns span over more than 4 billion light-years, but the asymmetry in that range is not uniform. The study found that the asymmetry gets higher when the galaxies are more distant from Earth, which shows that the early universe was more consistent and less chaotic than the current universe.

But the patterns do not just show that the universe is not symmetric, but also that the asymmetry changes in different parts of the universe, and the differences exhibit a unique pattern of multipoles.

"If the universe has an axis, it is not a simple single axis like a merry-go-round," Shamir said. "It is a complex alignment of multiple axes that also have a certain drift."

Why is there a normal galaxy sitting at the edge of the universe?

"Massive stars blow powerful winds, supernovae detonate like flashbulbs, and all that energy released should stir the gas up in the galaxy, making it irregularly shaped (plus, that early in the age of the Universe there just hadn't been a lot of time to get organized). Most distant galaxies we see are indeed blobby. The fact that this galaxy has a disk that appears to be pretty calm and stable is bizarre."

"Interestingly, it’s not alone. Earlier in 2020 astronomers announced they found a disk galaxy at about the same distance, called the Wolfe Galaxy. Like this one, it’s not understood how it can exist. Clearly, the theoretical models are wrong, or at least (and more likely) incomplete. Obviously, there’s more to learn about galaxies that exist at the edge of the observable Universe."

Scientists Detect Hints of Strange New Physics in The Universe's Background Radiation


"As far as we have been able to measure so far, there's only one fundamental interaction that breaks parity symmetry; that's the weak interaction between subatomic particles that is responsible for radioactive decay. But finding another place where parity symmetry breaks down could potentially lead us to new physics beyond the Standard Model."

"And two physicists - Yuto Minami of the High Energy Accelerator Research Organisation in Japan; and Eiichiro Komatsu of the Max Planck Institute for Astrophysics in Germany and Kavli Institute for the Physics and Mathematics of the Universe in Japan - believe they have found hints of it in the polarisation angle of the CMB."

Are primordial magnetic field theories getting in a twist?

"In cosmic voids where the density of galaxies is far lower than standard, astronomers have observed weak magnetic fields that may provide a window into the early universe. The fields 10-17-10-10 G in magnitude with large coherence lengths of up to megaparsecs are thought to have their origins in the early universe, but so far it is unclear when or how they were generated."
