Fermi Paradox and What is Extraterrestrial Civilization?
Scientists are wondering about how intelligence arises along with evolved in the universe which might have dissimilar or similar biological and social structures which might have developed individualistically from each other. The science domain, which is called Astrobiology, propelled astrobiologists to figure out any trace of the existence of alien life in the universe.
As of now, exploring the plants which might be habitable has forced astrobiologists to find any possible life beyond Earth, which raises questions about the actual presence of alien civilization as there is no clear evidence concern to this aspect identified. However, this does not mean that beyond our planet, there is no life, but there is no clear and concise detail about the presence of Extraterrestrial civilization that has yet to be identified. It remains the biggest mystery that scientists try to disclose.
In our universe, is there any possibility of a habitable planet?
The definition of habitability is one that in planets that can sustain any life for a longer timeframe. Based on our solar system, life requires energy, nutrients and liquid water to stay alive. The habitable zone is a region of the universe where planets can plants can obtain the required amount of heat from nearby stars to uphold liquid water on their surface. The Earth resides in a habitable zone as the Sun has played a key role in providing adequate heat and nutrients, which are required for any life form to sustain and thrive.
Nevertheless, many researchers revealed that in extreme environments that can sustain life, the needs for habitability on exoplanets are redefined. It has been recognized that even in the habitable zone, planets might not be habitable, and planets that orbit around stars that produce high levels of UV and X-rays could end up exposed to their atmosphere, leading to planets that might be warm but totally airless. NASA’s Sellers Exoplanet Environments Collaboration” SEEC facilitated this space agency to comprehend various planetary environments that could generate detectable biosignatures, which might provide a better outlook for understanding the true picture of the environment where any life could be sustained for the long run.
Fermi Paradox
In the vast universe, there are lots of unknowns that are yet to be unfolded and many questions we ask ourselves when looking at the cosmos, that encompass planets that orbit around stars. The search for Extraterrestrial life has become a driving force that has attracted the attention of scientists to disclose the actual truth about the existence of alien life. In the context of the Fermi Paradox well, known Nobel-winning physicist Enrico Fermi physicist that any civilization with advanced technology could have a tendency to rapidly colonize the entire galaxy.
The “Fermi Paradox” is the ostensible conflict between the facts that humans still have not found any evidence of alien life despite the likelihood of its presence in different galaxies. In our galaxy, there are around 400 billion stars, which elevates the possibility of planets which might be habitable and might also sustain life.
As many stars are billions of years old and thereby it is worth mentioning that the Extraterrestrial civilization that could exist might have advanced technologies that facilitate interstellar travel as per the Fermi Paradox.
However, there is no clear sign that could indicate the existence of intelligent life. In addition, some examples suggest that intelligent life is rare than we thought, and current scientific understanding of the true nature of the universe itself has been identified to be vastly incomplete, which increases the inconsistency between the lack of conclusive evidence of advanced Extraterrestrial civilization and higher possibility about its existence which is called Fermi Paradox. This forced astronomers to solve the “Fermi Paradox” by identifying any possibility of alien life in the universe.
