A paper based on observations published by Lior Shamir, an assistant professor of computer science at the University of Kansas, may challenge the currently widely accepted view of the universe. Shamir’s data supports previous theoretical assumptions, called the “tired light theory.”
Current scientific ideas about the origin of the universe are based on the work of Edwin Hubble and Georges Lemaître. Hubble discovered in the late 1920s that the farther away a galaxy is, the faster it recedes. Based on this, Belgian physics professor and Catholic priest Georges Lemaître concluded that the universe is expanding, that is, galaxies are moving away from each other, going back in time and meeting at a point, the beginning, that is, the Big Bang 13.8 billion years ago.
All this is due to the redshift of the light from the galaxies observed by Hubble. Redshift is a result of the Doppler effect, which describes the motion of waves and their observer, and is often illustrated by the sound of a passing spacecraft's horn. As the source approaches, the horn becomes louder, and as it recedes, it becomes deeper. As a result, the light from galaxies shifts bluer as they approach, and redder as they recede.
However, according to a now-defunct theory, the distance between galaxies does not actually increase, but the light loses energy and is redshifted. This was Fritz Zwicky's theory of tired light in 1929.
Sometimes he comes out of the drawer.
Fritz Zwicky was a Swiss astronomer who lived most of his life in California. He wasn’t Caucasian at all, but he was the Caltech professor who first wrote about dark matter, or neutron stars from supernovae, or how galaxies can bend light as gravitational lenses.
So Zwicky was a pioneering astronomer, and there were dozens of solutions to the light fatigue theory, all of which centered on the fact that photons somehow lose energy when they interact with intergalactic matter. The theory had come up from time to time, but since no factors were found to support it in other phenomena, such as the evolution of galaxies, time dilation, or the cosmic microwave background radiation, it was finally abandoned.
It has been included among the marginal theories.
In his latest paper, Lior Shamir re-established the theory based on redshift measurements of 30,000 galaxies, which he believes are also supported by measurements from the James Webb Space Telescope, which go back to the beginning.
The James Webb Space Telescope has provided deep images of the early universe, but instead of a newborn universe, it has revealed large, mature galaxies. If there was a Big Bang, as scientists believe, these galaxies are older than the universe itself.
– Shamir explained, who also found other strange differences.
The specialist examined galaxies located in different directions of the Milky Way. According to the results, galaxies rotating in the opposite direction to the Milky Way have a smaller redshift than those rotating in the same direction.
Since the Earth's rotation speed is constant compared to the galaxies, the reason for the difference is the distance between the galaxies, i.e. the displacement changes with distance, which is what Zwicky's theory predicts.
Shamir pointed out.
