Aliens May Destroy Humanity To Protect Other Civilizations, Say NASA Scientists
In the text they argue that the increasing emission of greenhouse gases can show the ETs that we are an expanding threat.
According to them, aliens may be following changes in the Earth’s atmosphere as an indication that our civilization is growing without limits and may take drastic measures so that we do not become a serious threat.
This is one of several scenarios described by scientists who, despite believing it to be unlikely, believe it is important to prepare humanity for contact. They divide the hypotheses into three categories: Beneficial, Neutral and Alarming.
The good ones range from the mere detection of extraterrestrial intelligence by, for example, intercepting alien communication, to contacting cooperative organizations that can help advance our knowledge and solve global problems like hunger, poverty and disease.
Another good result would be defeating a group of aggressive ETs or even being saved by another group of aliens. In this case, humans, in addition to leaving with the highest morale for victory, could still learn about extraterrestrial technology.
The most unpleasant results would arise if they caused harm to humanity, even by accident. ETs can come to feed on us, enslave or attack us, but people can still suffer from alien diseases. They might even want to carry out catastrophic experiments that could wipe out a part of the galaxy.
To increase humanity’s chances of survival, researchers urge caution when sending signals into space and in particular warn against releasing information about our biological makeup that could be used to manufacture weapons. Instead any contact with ETs should be limited to mathematical discourse “until we have a better idea of the type of ET we’re dealing with,” the authors said.
Extraterrestrials may be wary of civilizations that expand too quickly, as they may be prone to destroying other people’s lives as they grow, just as humans drove Earth’s species to extinction. In the most extreme scenario, aliens may choose to destroy humanity in order to protect other civilizations.
That is why they call attention to the reduction of the emission of greenhouse gases, which alter the Earth’s atmosphere, which can be seen from space and would indicate to extraterrestrials that our civilization is expanding. If we already have enough reasons to avoid the emission of gases to preserve life on the planet, we just won one more!
