Alien civilizations more likely to be hostile

American researchers predict that if there really are alien civilizations, they are likely to be hostile to the Earth, the Daily Mail reported.

Viewed from a third party, Earth may be seen as being hazardous as it shows an abnormal increase in temperature and therefore aliens may conduct a preemptive attack to protect themselves, the scientists said.

The report “Would Contact with Extraterrestrials Benefit or Harm Humanity,” written by NASA’s Planetary Science Division, supposed several possible outcomes in case of contact with alien civilizations.

Although the newcomers may try to share their technologies to overcome domestic problems like poverty, they may also attempt destruction or spread disease to eliminate the entire population, the report read.

“A preemptive strike would be particularly likely in the early phases of our expansion because a civilization may become increasingly difficult to destroy as it continues to expand.”

“These scenarios give us reason to limit our growth and reduce our impact on global ecosystems. It would particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets,” it added.

외계인, 만약 존재한다면 지구에 적대적

미국의 과학자들이 만약 지적인 외계생명체가 존재한다면 지구에게 적대적일 가능성이 많다고 추측했다.

미 항공우주국 (NASA)의 논문 “외계인과의 접촉: 인류에게 이로운가 해로운가” 는 우주인들이 만약 지구를 발견한다면 비정상적인 기후변화 등 때문에 우주 전체에 위험이 될 수 있다고 판단, 공격을 가할 수도 있다고 주장한다.

외계인과의 접촉이 기술 교류 등 우호적으로 나타날 수도 있지만, 최악의 경우 물리적 공격이나 병균 살포 등을 가할 수도 있다고 NASA 연구진들은 말했다.

과학자들은 이러한 선제 공격에 대한 가능성을 제기하면서 “행성의 대기 상태는 외부에서도 관찰될 수 있다”며 “온실 가스 배출을 조속히 규제해야 한다”고 덧붙였다.
