Scientist Frederick Walter from the State University of New York at Stony Brook (USA) has proposed a new theory to explain the lack of detection of intelligent aliens.
This was reported by the Popular Mechanics portal.
He believes that the Universe itself could destroy potential alien civilizations without giving them a chance to make contact with Earth. This creates interest and encourages further study. According to Walter’s theory, large-scale cosmic explosions such as gamma-ray bursts, which are the brightest eruptions in the Universe, may be the reason we have not yet discovered alien civilizations.
Gamma-ray bursts emit enormous amounts of energy and light, surpassing the Sun by millions of times and creating energy that the Sun takes billions of years to create. However, these explosions last only a few seconds, which may make it impossible for alien civilizations to survive as a result.
Scientists continue to debate the causes of gamma-ray bursts, but there is speculation that they may result from the merger of neutron stars or neutron stars with black holes. There is also the idea that gamma-ray bursts may be caused by massive stars turning into black holes after a supernova explosion.
Walter suggests that the high-energy radiation from gamma-ray bursts has the potential to rule out the existence of intelligent life on other planets. From his point of view, these bursts are powerful, narrowly directed beams that can penetrate galaxies and destroy life on about 10% of the planets in them.
According to the new theory, gamma-ray bursts occur approximately every 100 million years in any galaxy. However, some scientists believe that they can appear much more often – every 10 thousand years. As a result, many such bursts could occur within one billion years, which, according to this theory, could lead to the disappearance of many alien civilizations.
Some researchers have even hypothesized that gamma-ray bursts could wipe out life on Earth, but opponents argue that this is unlikely given the rarity of such explosions and their small number in the Milky Way.
Frederick Walter’s new theory joins many other hypotheses scientists have sought to explain the lack of contact with intelligent aliens. Some of these theories suggest that aliens are simply not interested in exploring deep space, or they don’t find our planet attractive enough.
Previously, Cursor wrote that studying planets with low carbon dioxide content in their atmospheres can be an effective method of searching for extraterrestrial life. This is due to the fact that carbon dioxide is one of the indicators of biosphere activity on the planet.
