Especially in 20 17, when you look back at this movie in 20 14, you will find that this science fiction is not science fiction. Many of them are based on reality or have become reality. In fact, corn is one of the few crops that can withstand extreme weather. Especially in the United States, corn has been planted for more than 7000 years. After continuous cultivation, it has become one of the most important crops in the world and has a wide range of uses. Moreover, corn, soybean and wheat are listed as the three major grain futures in the world, and their importance is self-evident.

According to Einstein's general theory of relativity. It's no problem to understand this theory that gravity generated by objects with sufficient mass will distort space-time, but it's interesting if we can put this statement together with two news stories in the middle of 20 16 and the beginning of 20 17: one is the sensational "scientists detected gravitational waves in space", which is called "hearing the breath of the universe"; The other is the legendary "a livable planet similar to Earth was found somewhere in the universe 4 1 light-years away from the Earth". That's interesting.

What impressed me most was that the man looked at the information sent by his children from the earth alone in front of the monitor. It is really a million years. Looking at his children from childhood ignorance to young people's rebellious recklessness, the first time he met the person he liked, the first time he was lovelorn, and the first time he became a father, all these things were not involved. The long life of people who look at their loved ones ends in a few minutes, and they can't participate in those joys and pains. He can't share the children's happiness, nor can he wipe away the children's tears, just watching them grow up in a world without themselves. This helplessness that I can only watch but can't participate makes me burst into tears in front of the screen.

Finally, we can understand that when a long life is condensed into a few minutes, we really realize what is the turning point that changes our life, but in it, we can't see the ending, and naturally we don't know which decisions will affect our later life. At that time, we thought it was just an ordinary day, and peace often made no difference.
