According to a new study, our galaxy has been colonized by extraterrestrial civilizations for millions of years.
Other civilizations may exist in the Milky Way, according to NASA specialists.
It’s odd that NASA publishes information on aliens. His latest research, on the other hand, has come to an almost conclusive conclusion: civilizations have existed in our galaxy for billions of years.
Scientists from the California Institute of Technology and NASA’s Jet Propulsion Laboratory collaborated on the research.
Alien cultures exist throughout the galaxy.
According to the study’s findings, this catastrophe occurred approximately 8 billion years ago. Following the formation of the Milky Way.
This suggests that our galaxy has hosted a variety of extraterrestrial civilizations in the past, all of which were either destroyed or destroyed themselves.
According to research published on arxiv.org, intelligent life in our Milky Way should have appeared at least 8,000 years after its birth. Experts estimate that the event occurred roughly 13 thousand light-years from the galaxy’s center.
Xiang Cai, Jonathan H. Jiang, Kristen A. Fahy, and Yuk L. Yung employed various statistical models to arrive at this conclusion, demonstrating the best timing for intelligent life to emerge.
This is based on a variety of characteristics, including well-known astrophysical aspects of the Milky Way as well as factors that aren’t typically considered, such as the abiogenesis process.
Abiogenesis is the process of creating life from non-living matter. This is thought to be the most likely route to the beginning of life.
When considering life in our galaxy, there are three factors to consider.
Civilizations have three basic parameters.
Life could emerge through the Poisson Process or abiogenesis, thanks to mathematical models that imply life is conceivable in stars comparable to the Sun, with planets similar to Earth.
Different evolutionary time scales and species self-annihilation were also taken into consideration.
According to the findings, self-annihilation is the most important element in predicting how long an alien civilization can persist in our galaxy.
Furthermore, results on a location for intelligent extraterrestrial life in an annular region, roughly 8 billion light years away, with complex life, were found, with the peak point diminishing temporally and spatially from the peak point. As a result, the Milky Way’s inner disk has a high possibility of sentient life.
The simulated age distributions clearly show that the majority of sentient life is young. It’s for this reason that observing or detecting it is so tough.
Is it possible to know for certain that we are not the Milky Way’s lone intelligent civilization? This research takes us closer to the truth about our origins and the possibility of coexistence with other civilizations.
