Galaxies separated by a vast stretch of distance appear to behave as if they are synchronized. Researchers do not as of yet have an explanation for the strange phenomena, although they suggest that it may have something to do with “The Cosmic Web” of electrified gas plasma that connects them together much in a similar way to how neurons communicate throughout the brain.
The research team observed a total of 445 galaxies within 400 million light years of Earth. What they found was that galaxies rotating toward the direction of Earth also had neighboring galaxies separated by 20 million light years that were rotating in the same direction, which shouldn’t be impossible.
Similarly, the ones that rotated opposite to Earth also had neighbors who were doing the same thing. The distances that separate them are too vast to be explained by gravitational phenomena. In other words, they appear to communicate as if they are connected by a “vast unseen force” which more closely approximates the strange world of quantum entanglement.
It is worth mentioning that scientists have verified quantum entanglement in objects that are almost “large enough to see with the naked eye”
“The observed coherence must have some relationship with large-scale structures, because it is impossible that the galaxies separated by six megaparsecs [roughly 20 million light years] directly interact with each other,” said Korea Astronomy and Space Science Institute astronomer Hyeop Lee
Furthermore, the milky way appears to be ingesting more gas then it is giving out, which they claim may be coming from either the Interstellar Medium or smaller nearby galaxies. They say that the lack of hotter gas may also play a role in contributing to the perception of imbalance, since they only included cooler gas in this particular study. Even then however, they will have to explain why our galaxy is absorbing more cooler gas then it is expelling with.
Like other galaxies, The center of our milky way is purported to contain a supermassive black hole called Sagittarius A. By observing the matter around this black hole scientists can make a reasonable deduction about the activity occurring within and around it.
In may of this year they observed an enormous eruption of energy in the infrared spectrum that blew all previous measurements right out of the water. This super flare was twice the size of a previous record holder and suggests that our galactic core is going through a particularly active phase of consumption and expulsion, at least since we have began observing it.
“The black hole is always variable, but this was the brightest we’ve seen in the infrared so far,” Tuan Do, an astronomer at the University of California, Los Angeles, and lead author of the new study, said on Twitter. “It was probably even brighter before we started observing that night!
Eruptions of electromagnetic energy from the galactic core are tracked at many different wavelengths of light including the highest frequency we can measure – called gamma radiation, the furthest reach of the ultraviolet spectrum.
When scientists fit the proper lens on to their telescopes they can view these other wavelengths of light like peering in to a whole other realm. Back in 2015 scientists identified two structures that were billowing out 23 000 light years away from the core of our Milky Way. They named them Fermi Bubbles and up until now they weren’t sure how old they were, nor what kind of plasma they were composed of.
Now, by referencing 46 different quasars they can observe how the light pierces through this giant cloud of radiation in order to determine the chemical composition, temperature and speed of the northern Fermi Bubble which allowed them to retroactively track the movement to determine it’s age.
Using this method they concluded that the northern bubble contains elements like silicon and carbon that were swept up by the initial burst of radiation. Furthermore they appear to be traveling out of the Milky Way at around 2 million miles per hour while burning up at 17 700 around degrees Fahrenheit, which is relatively cool in cosmological terms.
Using this information they were able to determine the age of the Fermi Bubbles and along with that – when Sagittarius A consumed it last huge feast of cosmic matter.
“What we find is that a very strong, energetic event happened 6 million to 9 million years ago,” Bordoloi explained. “It may have been a cloud of gas flowing into the black hole, which fired off jets of matter, forming the twin lobes of hot gas seen in X-ray and gamma-ray observations. Ever since then, the black hole has just been eating snacks.”
