外星人离我们并不遥远?
据英国《每日邮报》11月9日报道,美国白宫本周的一份声明称,现在还没有证据证明外星人已试图和地球联系或者他们真实存在。但是美国政府为何如此确定呢?
宾夕法尼亚大学的两名研究员雅各布·哈格-米斯拉(Jacob Haqq-Misra)和拉维·库马尔·库帕拉普(Ravi Kumar
Kopparapu)提出了这样的疑问,他们认为在现有科技水平下,人们还无法看透外太空,这就意味着或许我们发现不了外星人发出的信号,外星人很有可能就存在于太阳系。
科学家们还补充说,美国宇航局的“先锋号(Pioneer)”和“旅行者号(Voyager)”飞船可能太小了,以至于外星人没有看到;就算在地球上,随着科技的进步,我们在海底、雨林和洞穴中仍不断发现新的物种。
