当我们人类登上宇宙飞船,遨游在太空之中时,就会发现时间在变化,在变慢。其实,这仅仅是宏观世界的现象。可是,正如哲学上讲的,宏观和微观既对立又统一一样,在我们人类的受精卵这个微观世界之中,它在着床、发育时,时间也在相对变化,不过是变快。现在,让我们从受精卵的发展说起吧,虽然,在我们这个世界看来,从受精卵发育成为成熟的胎儿,约需280天左右,但是,对受精卵而言,它的发展是飞速的,从受精卵这个原始生命,演化成胚卵,演变成胚胎,发育成胎儿,其 When we humans ascend the spacecraft and travel in space, we will find that time is changing and we are slowing down. In fact, this is only a macro-world phenomenon. However, just as philosophically speaking, macroscopic and microcosmic are both antagonistic and unity, and in the microscopic world of our human fertilized eggs, time is relatively changing when it is implanted and developed, but it is faster. Now, let’s start with the development of the fertilized egg. Although, in our world, it takes about 280 days to develop from a fertilized egg to a mature fetus, its development is very fast for fertilized eggs. , from the primitive life of fertilized eggs, evolved into embryonic eggs, evolved into embryos, developed into fetuses, and
