Aliens Are There, but Our Theories Are Steering Us Away From It
If we discovered evidence of alien life, would we even realise it? Life on other planets could be so different from what we’re used to that we might not recognise any biological signatures that it produces.
如果我们发现了外星人生命的证据,我们会意识到吗?其他行星上的生命可能与我们习惯的不同,以至于我们可能认不出它产生的任何生物特征。
Recent years have seen changes to our theories about what counts as a biosignature and which planets might be habitable, and further turnarounds are inevitable. But the best we can really do is interpret the data we have with our current best theory, not with some future idea we haven’t had yet.
近年来,我们关于什么是生物特征以及哪些行星可能适合居住的理论发生了变化,而进一步的转变是不可避免的。但是我们真正能做的就是用我们目前最好的理论来解释我们所拥有的数据,而不是用一些我们还没有得到的未来的想法。
按图索骥,
贻笑大方,
能不能有所突破,
在于,
破除所知障。
没错,
正如理论,
既是工具,
也是牵绊。
