科学家为什么一定要联系外星人,为什么一定要找到外星人?

 

为什么一定要找外星人呢,有什么好处呢?在明知道可能会带来灾难的前提下,还是要寻找还是要联系(我们先抛开大刘书中的叶阿姨不提),难道科学家们发现了什么不可避免的灾难吗?

叶文洁于红岸基地进行了Ⅱ型文明能级的发射,三体星文明随之到来,最终太阳系被歌者文明的二维武器打几下最终毁灭。——《三体》

1.星体撞击

虽然宇宙广阔,撞击事件却从未中断。1994年7月,人类历史上从未有过的一次宇宙事件,那就是“苏梅克—列维9号”彗星(以下简称SL9)与太阳系中的最大行星——木星相撞。有木星这个大盾牌,有月球这个挡枪的小伙伴,有威胁的撞击却从未停止过。从恐龙的灭绝,到明代的天启大爆炸,其间还有无数的“旅客”光顾过我们的家园。NASA科学家发现,2029年4月13日将有一颗名叫“阿波菲斯”将在与地球擦身而过,届时这颗小行星与地球的之间的距离为18640英里,这个距离比多数的通信卫星与地球的间距还要近几千英里,稍有偏差的话……到时候只能期待布鲁斯·威利斯叔叔能飞天、挖坑、炸个球了。

 

2.自然灾害

【天气变化】科学家推测,地球天气受太阳系的星云迹象影响,目前,星云迹象十分稳定,所以地球天气没有出现极端状况,然而在地球上曾出现过的三大冰川期和已经考证的火海期告诉我们,情况并不乐观。地球天气被我们所未知的事物控制,这显然不是什么好现象,万一哪天就变冷了,全是冰川,我们建立个RedAlert的天气控制器估计也不管用。

【地壳运动】地壳运动会导致火山活动频繁,庞贝城就是这么没的,还有海啸等等。即便是地壳运动没有引起火山喷发和海啸,说不定再震漏了个核电站什么的也是真够了。

 

3.资源枯竭

地球上的人口从二战后人口总量约为21~24亿左右增长到如今的近70亿,几十年间人口总量翻了3倍,随之而来的是资源的过渡开采,能源的供应紧张。资源不足将会直接影响人类的生存,也会从侧面影响社会关系的稳定,比如对资源所有权的战争等等。

 

地球时刻都可能遇到毁灭性的威胁,我们只能不断寻找可居星球移民。这样才能使人类延续得到保障,其实我们不必冒更大的风险去找外星人,只要发现宜居的星球、足够的宇航技术,找到适合人类生存的第二家园就可以了。
