提到自然界中的生命,人们一定会想到碳、氢、氧、氮等元素构成了生命的基本单位──细胞。但这有没有可能是地球上的一个特例呢?地球上有能够在核反应堆等恶劣环境下生存的生物,由于其他星球上的环境与地球不同,那里也可能会产生适应该星球环境的生命,这些外星生物的生命单位甚至还有可能是由其他未发现的元素构成的。 When it comes to life in the natural world, people will think of elements such as carbon, hydrogen, oxygen, and nitrogen that make up the cell of life. But is it possible that this is a special case on Earth? There are living creatures that can survive in harsh environments such as nuclear reactors. Because the environment on other planets is different from that of the Earth, there may be life that adapts to the environment of the planet. Extraterrestrial life units may even consist of other undiscovered elements.
