The universe is crooked, according to two studies of a million galaxies

The universe is crooked, according to two studies of a million galaxies

According to astrophysicists and cosmologists, the universe is homogeneous. On the largest cosmic scale, galaxies are evenly distributed no matter which way we look.

Two independent analyzes covering up to a million galaxies suggest that this is not the case. The universe bends to one side.

One study was written by astronomers from the University of Florida, and the other from Lawrence Berkeley National Laboratory in California. The two papers were published on the ArXiv website, where they were published prior to the scientific review.

Study both astronomers Images from a Sloan Digital Sky survey (SDSS). This is one of the most important surveys of the sky, which began in the year 2000. Both groups tested the symmetry of the universe in a rather complex way (each galaxy was placed at the top of the pyramid and calculated if more pointed in a certain direction when viewed clockwise or in clockwise direction).

Theoretically, since the universe is homogeneous, there should be the same number of these imaginary pyramids in the image of any region of the sky, whether viewed from left to right or vice versa. It turns out that this is not the case. The universe is “crooked”, that is, it favors a certain direction.

The possibility of this being the result of chance or miscalculation is low. In the first study, it was about 0.4 percent. per second (which compared the galaxies closest to us and those farther away), it was smaller, because only 0.0000019 percent.

This is a very unpleasant fact for astrophysicists. They have no reason to believe that the universe was born in any special way. It expanded steadily after the Big Bang. Even if there are some primordial densities of matter, they must be mitigated by rapid expansion (called cosmic inflation). We shouldn’t see them today.

Scientists have no idea what could be the cause of this Galaxies in the universe frequently line up in a certain directionunku. These may be as yet unknown physical laws that break symmetry (although some do, too). Astronomers want to repeat similar studies, but in different ways.

Interestingly, previous research has also indicated that the universe is not symmetric.

Data analysis from the Sloan Digital Sky Survey conducted by Michael Longo of the University of Michigan in 2010) covered 15,000 galaxies. In a work published in “Physical Review Letters C” he described that when we look in a particular direction from the sky, Often times we find galaxies heading to the leftcounter clockwise. The odds of this being an error were 0.006.

According to Longo, that could only mean one thing. The universe must rotate, and galaxies rotate repeatedly in line with their axis of rotation. However, these studies were forgotten.

A similar conclusion was reached by researchers from Kansas State University in 2020, who presented the results of their analyzes at the American Astronomical Society conference in June two years ago. They used other galaxies observed by other telescopes.

So maybe something is wrong. The universe is crooked or spinning. Galaxies often rotate in the same direction for unknown reasons.
