If our universe is truly isotropic, there should be no inherent bias in the rotational directions, which means that almost equal numbers of galaxies should rotate clockwise (50 percent) and anticlockwise (50 percent) — but this isn’t the case.
The researchers discovered that nearly one-third of the galaxies in the survey rotated anticlockwise, and over two-thirds showed clockwise movement.
“The analysis of the galaxies was done by quantitative analysis of their shapes, but the difference is so obvious that any person looking at the image can see it. There is no need for special skills or knowledge to see that the numbers are different. With the power of the James Webb Space Telescope, anyone can see it,” Lior Shamir, study author and professor at Kansas State University, said.
This finding suggests that our universe has a favored galactic spin direction — but why?
