1 前言
我们先给个小故事,提一下大家兴趣;然后我给出论据,得出结论。最后再浪漫的流星雨表白代码奉上,还有我自创的一首诗。开始啦:
2 霍金说移民外太空
霍金说我们将来外星上生存;埃隆.马斯克也是这样想的。
我前面讲外星人来不到地球,这个道理已经很清楚。我再说几个数据,大家听听,我们且不要说到更远的外星,我们人类今天登上月球,把一个字航员送上月球,他在月球上待一分钟,要消耗地球一百万美元的资源才能在月球上待一分钟 。
我们说未来在火星上殖民,想想你在月球上一个人待一分钟,要消耗地球一百万美元的资源,你在火星上殖民几千人、几万人,你得把整个地球资源毁灭掉,都调到火星上去。然后你只把七十亿人调过去了几千、几万人,然后他在那可能死得更快,这根本不是出路,这怎么会成为出路呢?
我们再看,移居外星,离我们地球最近的另一个恒星系叫半人马座。半人马座,阿尔法星
也叫比邻星。大家注意,这都是恒星,比邻星距离太阳最近,有多近? 4.2光年,光以每秒钟三十万公里,走4.2年,就这我们还不知道比邻星的那个恒星旁边有没有行星。
就算有行星有没有宜居行星、类地行星。这我们还全然不知道。我们就假定那个地方有好了另一个地球,你按照今天人类火箭和卫星的最高速度,你单程从地球上飞到比邻星,需要一万五千年到三万年。
请注意我们文明史,文明有文字,以后的文明迄今才五千年,你单程飞到那个地方要一万五千年以上。我说过有没有行星都不知道。这个前途存在吗?根本不存在。就像外星人来不了我们这儿一样,我们也到不了任何外星存在。
我们今天连太阳系都没有走出去,没有在太阳系的任何一个行星上殖民,所以移民外星根本不是出路。
