This was announced by the press service of the Chandra Space Observatory.
"We found significant differences in how individual regions of the universe expand, observing hundreds of galaxy clusters distant from each other. If differences actually exist, this discovery contradicts the fundamental principle of modern cosmology,” said astrophysicist Gerrit Schellenberger of Harvard University.
At the end of the last century, scientists found that the universe was expanding at an accelerated pace. Specialists today believe that the reason for its accelerated expansion is the so-called dark energy, the nature of which is among the great mysteries of modern science.
In accordance with the cosmological principle of Copernicus, the same laws of physics are in force at any randomly selected point of the universe. Therefore, at the same moment, the universe should look and expand equally, regardless of the location and direction of observations. At the beginning of this century, scientists first discovered signs that this might not fit the truth.
In 2006, astronomers under Joao Mageizhu came across an unusual structure in the microwave “echo” of the Big Bang, which cosmologists today call the “axis of evil.”
While studying relict radiation, scientists found that its energy in one section of the universe is greater than in another stretch. A number of specialists have suggested that the existence of a similar anomaly means that some regions of the universe are expanding faster than others. While analyzing data collected with Planck and WMAP telescopes, which examined the “echoes” of the Big Bang, scientists later found both further confirmation of the existence of an “axis of evil” and arguments against its existence.
Shellenberger and his colleagues examined many X-rays from 300 randomly selected bright galactic bowls observed by Chandra and European missions HMM-Newton and ROSAT, and received new evidence supporting the hypothesis of the universe's non-uniform expansion.
Chandra Telescope: Universe expands unevenly
While analyzing images taken with the Chandra Space Telescope of distant galaxy clusters, Harvard University astronomers and their German colleagues found new evidence to support the claim that the speed at which the universe expands is not the same in separate sections of it. handed over TASS and BTA.tags:
