If the universe is rotating, it may be related to the rotation direction of the universe itself, then galaxies located in the two hemispheres of the universe must have different rotation directions
Researcher Michael Longo from the University of Michigan After using the 2.5-meter aperture telescope at Apache Peak in New Mexico, the Sloan Digital Sky Survey (SDSS), with his colleagues to study more than 15,000 galaxies in the universe, he stated in his report: According to the rotation of the galaxies In-depth study of the direction, whether it is a spiral galaxy rotating clockwise or counterclockwise, the direction of rotation is not random, but may be determined by the hemisphere of the universe in which the galaxy is located. The distances of most of these galaxies are within the distance In the cosmic space 600 million light-years away from the earth, about one-twentieth of the galaxies are the farthest galaxy group that humans can observe so far.
Looking into the sky of the northern hemisphere, it is about above the direction of the Milky Way. , more than half of the observed galaxies rotate in the counterclockwise direction. However, the observed sample of galaxies appears to be a bit small, because these galaxies only account for 7% of the total number of galaxies. And if galaxies If the rotation direction of the galaxy is random, then the probability of observing so many counterclockwise rotating galaxies at the same time in the same sample is only one in a million. This means that the rotation direction of the galaxy is affected by some mechanism. and effects, and the effects of these effects can be reflected in larger-scale cosmic spaces.
If the entire universe is rotating, then the galaxies located in the two hemispheres of the universe must have different rotation directions, that is, Most of the rotation directions of galaxies below the Milky Way and those above the Milky Way should be different, and these galaxies should rotate in a clockwise direction. To address this issue, researchers investigated the results of 8,287 spiral galaxies in the southern sky in 1991. The research report found that these galaxies do indeed rotate clockwise. However, the data from the Sloan Digital Sky Survey is largely limited to the celestial sphere north of the central plane of the Milky Way. Therefore, researchers currently need to further confirm that in the southern hemisphere What proportion of the total number of spiral galaxies have clockwise rotating galaxies, and this confirmation was also completed by the telescope on the top of the mountain in New Mexico.
Through the understanding of the above research, we can further speculate: in the universe The galaxies are rotating, the stars and planets are also rotating, then, is the entire universe also rotating? If this view is proved to be correct, then the significance of this rotating universe is very far-reaching, and modern cosmology The cornerstone theory believes that the universe is uniform and isotropic, which means that it is the same no matter which direction it is viewed from. The universe does not have special characteristics in a certain direction. Faced with this problem, the universe should be There is an axis of rotation. This theory has to impact Copernicus's heliocentric theory and the view that humans are not the center of the universe. In other words: If the universe has an axis of rotation, it means that the universe has a special direction.
Observing galaxies with opposite rotation directions in the northern sky and southern sky infers that the universe rotates around an axis of rotation. This also makes people think: the reason why the universe rotates may be due to an impact at the beginning of its birth. An unusually strong impact of angular momentum. Is this perhaps the first driving force? It may also mean that at the time of the Big Bang, there was a mysterious rotational energy in the original universe, or at least there was a primitive super fireball vortex. And the current rotation of the galaxy The direction is the "fossil" evidence left by these vortices. This is just like the early formation of our solar system with a huge rotating gas and interstellar dust disk surrounding the newborn sun, and the current information about the rotation of the planets in the solar system is also in that It will leave its mark when time passes.
As for the issues related to the rotation speed of the universe, no cosmological theory has yet predicted it. In fact, if the universe is admitted to rotate, this will make the existing cosmological theories believe that The view that the universe is uniform in any direction has been greatly impacted. The cornerstone of cosmology will be shaken. This is not the first time that cosmologists have doubted whether the universe is rotating. When studying the cosmic microwave background radiation of the Big Bang, Similar suspicions arose. At the same time, researchers
Researchers also analyzed that the survey and analysis of the Sloan Digital Sky Survey may only see a small part of a larger and more uniform universe, but the study of the rotation directions of galaxies in different hemispheres expands our speculation theory about the larger universe.
This result may also be a lucky statistic. Have we been observing a small universe all this time? When timing the northern and southern hemisphere star systems, the rotation axis of the Milky Way seems to be miraculously aligned with the imaginary universe. Axis of rotation. This idea could have been extremely bad news for Copernicus, as it would suggest that we are likely to be at the center of the universe, largely hinting at the cosmocentrism mentioned in the Bible. Faced with this extension This inference shows that our astronomical research may still be just a frog in the well, because the famous astronomer Carl Sagan has a famous saying: Extraordinary conclusions require extraordinary evidence.
