Scientists have given several answers to the question, How would our Earth change if aliens existed?
Undeniably, the human space science industry has made great progress compared to the beginning, but so far, there has been no discovery of another civilization in the universe.
Recently, Seth Shostak – a leading astronomer at the SETI Institute, California (Search for Extraterrestrial Intelligence) confirmed that he will find evidence of aliens before 2040, thanks to into electromagnetic and radio signals in space.
It’s not certain if his claim will come true, but the question arises: if there is absolute evidence of life beyond Earth, how will the planet of humanity change? Let’s come to the answers of some researchers according to information from the Io9 site.
From the initial assumptions
The researchers who entered to answer this made assumptions. First, this historic discovery will be discovered in the near future. After that, humans could only communicate with visitors from space by means of electromagnetic signals. And in the end, extraterrestrial civilization will only be below or equal to, or not far above, human.
…to bigger impacts…
“Many people think that extraterrestrial signals will not affect humanity,” said Milan Cirkovic, a research assistant at the Belgrade Observatory and an expert at the SETI Institute.
But according to him, based on the theory of astronomer Carl Sagan (1934-1996), the discovery of evidence of another species in the universe will have huge impacts on humanity.
It is particularly influential in many fields of science and even anthropocentrism. Carl Sagan once mentioned, the signals of alien life will be a great encouragement for space science, both in research and space habitation projects.
However, this hypothesis put forward by Sagan in the last century did not attract many people’s attention. But at the present time, when science has advanced greatly, researchers are eager to learn and feel excited, eager to explore the universe to meet this “neighbor”.
Cirkovic predicts that, if this were to happen, about half of today’s science would be seriously skewed. However, some argue that humanity should entrench, find a way to escape, instead of trying to find potential dangers outside the universe. Some even say, humanity needs weapons to fight the threat from aliens.
And the effects on the development orbit of the planet
So how will the discovery of “intelligent extraterrestrial beings” affect the development of civilizations? Mr. Cirkovic said that the astronomer Sagan had identified agents from any early civilization.
Sagan believes that any civilization that has an environment to interact with the universe (seeing stars in the sky, seeing objects in the universe), will have a desire to learn and discover about it. But there can also be exceptions, if a species evolved in a completely different environment – like Jupiter, with the largest atmosphere in the Solar System but obscured, unable to see the universe – it would be less interesting. interested in things around their planet.
According to Milan Cirkovic, if Sagan’s hypothesis is correct, the discovery of an extraterrestrial civilization at this stage would be a great thing. In addition to the impact on the development of space science and technology, it also gives the motivation for scientists to explore and conquer space.
And even aliens can incite cultural and political changes, form parties, or give birth to some new religions, or make some existing religions disappear.
There is also a possibility that nothing will change. Extraterrestrial signals will make no difference when scientists or politicians… keep it hidden from the people.
However, the worst possibility occurs, which can lead to hysteria and paranoia in society. Or more ironically, finding a civilization equivalent to that of humanity could become the basis for the “great selection” theory in the evolving Fermi Paradox.
This paradox refers to the fact that civilizations automatically seek and destroy each other, leading to the demise of the entire universe. And who knows, this may cause scientists to falter when looking to a more distant future, where humanity conquers all over the universe.
