Aliens May Destroy Humanity to Protect other Civilisations, Say Scientists

Aliens May Destroy Humanity to Protect other Civilisations, Say Scientists

Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report.

It may not rank as the most compelling reason to curb greenhouse gases, but reducing our emissions might just save humanity from a pre-emptive alien attack, scientists claim.

Watching from afar, extraterrestrial beings might view changes in Earth’s atmosphere as symptomatic of a civilisation growing out of control – and take drastic action to keep us from becoming a more serious threat, the researchers explain.

This highly speculative scenario is one of several described by a Nasa-affiliated scientist and colleagues at Pennsylvania State University that, while considered unlikely, they say could play out were humans and alien life to make contact at some point in the future.

Shawn Domagal-Goldman of Nasa’s Planetary Science Division and his colleagues compiled a list of plausible outcomes that could unfold in the aftermath of a close encounter, to help humanity “prepare for actual contact”.

In their report, Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis, the researchers divide alien contacts into three broad categories: beneficial, neutral or harmful.

Beneficial encounters ranged from the mere detection of extraterrestrial intelligence (ETI), for example through the interception of alien broadcasts, to contact with cooperative organisms that help us advance our knowledge and solve global problems such as hunger, poverty and disease.

Another beneficial outcome the authors entertain sees humanity triumph over a more powerful alien aggressor, or even being saved by a second group of ETs. “In these scenarios, humanity benefits not only from the major moral victory of having defeated a daunting rival, but also from the opportunity to reverse-engineer ETI technology,” the authors write.

Other kinds of close encounter may be less rewarding and leave much of human society feeling indifferent towards alien life. The extraterrestrials may be too different from us to communicate with usefully. They might invite humanity to join the “Galactic Club” only for the entry requirements to be too bureaucratic and tedious for humans to bother with. They could even become a nuisance, like the stranded, prawn-like creatures that are kept in a refugee camp in the 2009 South African movie, District 9, the report explains.

The most unappealing outcomes would arise if extraterrestrials caused harm to humanity, even if by accident. While aliens may arrive to eat, enslave or attack us, the report adds that people might also suffer from being physically crushed or by contracting diseases carried by the visitors. In especially unfortunate incidents, humanity could be wiped out when a more advanced civilisation accidentally unleashes an unfriendly artificial intelligence, or performs a catastrophic physics experiment that renders a portion of the galaxy uninhabitable.

To bolster humanity’s chances of survival, the researchers call for caution in sending signals into space, and in particular warn against broadcasting information about our biological make-up, which could be used to manufacture weapons that target humans. Instead, any contact with ETs should be limited to mathematical discourse “until we have a better idea of the type of ETI we are dealing with.”

The authors warn that extraterrestrials may be wary of civilisations that expand very rapidly, as these may be prone to destroy other life as they grow, just as humans have pushed species to extinction on Earth. In the most extreme scenario, aliens might choose to destroy humanity to protect other civilisations.

“A preemptive strike would be particularly likely in the early phases of our expansion because a civilisation may become increasingly difficult to destroy as it continues to expand. Humanity may just now be entering the period in which its rapid civilisational expansion could be detected by an ETI because our expansion is changing the composition of the Earth’s atmosphere, via greenhouse gas emissions,” the report states.

“Green” aliens might object to the environmental damage humans have caused on Earth and wipe us out to save the planet. “These scenarios give us reason to limit our growth and reduce our impact on global ecosystems. It would be particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets,” the authors write.

Even if we never make contact with extraterrestrials, the report argues that considering the potential scenarios may help to plot the future path of human civilisation, avoid collapse and achieve long-term survival.

Perhaps no time left. Humans are destroying themselves.

This can be an excuse.

Is this supposed to be an April Fool’s joke?

Guest

We ,as a race are to hostile right now to be allowed to risk having or coming close to the technology of deep space travel

Guest

No way. Human will destroy human and humanity. No need for Alien invasion or anything else. Look around whats happening to this planet.

Guest

Two choices, Take the bad and put them on another planet or leave the bad here and take the good to another planet, Some of mankind will not change and are beyond help!!!

Guest

Yes I’d be happy with whatever, I’ve just had enough of all the bad stuff that’s going on!!!

Guest

your statement is right..I’ll choose the first choice you had mentioned…

Guest

What if it already tried to happen with the Annihilation of Nephlims.

Guest

Transport all the corrupt families, alien entities and government officials off the planet and we may have a chance

Guest

end religion and it may just be ok

Guest

Need to do more than that

Guest

Scientists just wanna frighten people.

Voce acha mesmo,da uma olhada no curriculo da humanidade de 200 anos ate hoje.Ganancia,poder,guerras,muita maldade,indiferente a tudo ,meio ambiente sendo devastado,a vida sem nenhum valor,e muito mais.O homem nao faz falta neste planeta ,acho q sera isso mesmo,ou seremos destruidos de vez ou seremos dominados por civilizaçoes bem mais potente tecnologicamente.O homem nao tem condiçao de convivencia com outras raças se ele a nao dominar,e agora estamos no fio da navalha em um confronto com essas civilizaçoes nao teremos chances de nenum exito.Infelizmente ou felizmente sera assim,porque nao temos nada a oferecer para estas civilizaçoes que nos vĂŞ como uma… Read more »

I don’t think the threat is much E.T (extraterrestrial beings) more than our selves, if we continue polluting the world the way we currently all, drilling oil in the artic ocean, cutting tress & burning them down, if we do not cut down co emission, if we keep consuming and generating bunch of waste (chemical, ewaste, etc) Then yeah we will destroy our own place, I don’t think e.t will need to worry about that. HUMAN ACTICITY is the number one cause for all the damage being done to the planet we live in, we should worry about that instead… Read more »

If aliens wanted to do that they would of already done it.

“Among US” is a one-hour scripted sci-fi drama TV series inspired by real world events throughout history (Nazi Flying Bell, MK Ultra, Human Genome Project, Area 51, Pyramids, only to name a few) that not only spell out the fact that we as humans have been coexisting with “aliens” since the dawn of our species but also that conspiring powers have and continue to blind us to this fact. Our goal is to build an audience and sell this one hour Sci-fi Drama for the world to wake up. To do this, we need for those of you out there… Read more »

It seems to me that we destroyed any chance we ever had of re-entering the Cosmos Traveller Family long ago. We’re a day late and a dollar short!

What do the aliens have to say about what we are doing to our planet, and what’s going to happen to us?

Guest

Yeah. . No.

Guest

GOOD . I LIKE THAT .

Guest

“Say scientists”…

Say the “experts”…

Who cares what scientists think… may as well ask the pope…

Howard Bamber
Guest

The Pope knows all about ufos and alien life. The Church has had contact from the beginning. On the death of the last Pope there was a ufo hovering above the Vatican at the time of his death. There are clear pictures of this and plenty of eyewitness. They were paying their respects. The Pope has said, on record there is extraterrestrial life.

Guest

We can only hope?✌️

Guest

If they wanted to destroy humanity they would of already done so

Guest

Scientists have all kinds of theories about everything , but they are not always right. We don’t need aliens to destroy mankind.

Guest

Not all..

Guest

The invasion began along time ago. …..they have helped us get all of our technical wonders….we have become dependent on it…..not much longer and they will pull the plug. ……….and then where will we be……A lost civilization. ….A threat to no body. …just a laboratory for experiments. ..more than we are now

Guest

Don t be deceived

Guest

Which one?

Guest

Say scientists – politicians (more politicians then scientists)

Guest

thiers is not on Earth.

The composition of the earth's atmosphere has changed before in the past, and will change again in he future. Hardly worth an Et's second glance. Mankind will solve his own problems. We know what they are, and we know what the solutions are. The biggest problem, which when solved will eradicate most of the other problems, is persuading the greedy rich to contribute more to the general coffers!

If E.T.'s are real, they could have erased us off this planet already. If we further speculate that E.T.'s are of a Higher intelligence and thus have more avanced technology than our own, to ensure our planet's survival they would opt for a viral / chemical weapon to decrease the population and de-weaponize Governments and civilians and occupy this planet to maintain its edicts while furthering their own agenda. Benign E.T.'s again, if they exist, would NOT interfere. Ethically and morally a being cannot interfere or otherwise damage the natural evolution of lesser evolved species. If they do? It is… Read more »

LOL, this article is comical. It's saying maybe the threat of being annihilated by ETI could stop humanity from destroying itself and the planet. Baa Humbug, I say to that. Where were they thousands of years ago before Atlantis was destroyed? Where were they when the so-called great flood happened? Where were they when Mars, supposedly destroyed itself? What about their intercession when Venus was in trouble? Too funny, if they are smart, they will not bother us, cause we can take em on!!! And we can still destroy our planet and move out into the Cosmos with our diseases… Read more »
