人們瞭解什麼是時間之前，其實已經將它消磨了一半。因為困惑不解，所以未曾停止對於時間和空間的探索，時間快慢是感覺? 還是有科學根據？愛因斯坦曾用相對論來說明時間，坐在燙熱的火爐旁邊，會覺得時間過得特別慢，如果跟情人約會，會覺得時間過得特別快。美國史丹福大學的神經科學教授伊格曼（David Eagleman），認為大腦處理新穎事務時會耗費較多能量，紀錄下更多的記憶，童年時每天都學新東西，覺得時間過得特慢。長大後習以為常的體驗，腦子見怪不怪，時間會感覺越過越快。就像去一個新的地方，總覺得去的路顯得特別的長，回程熟悉那條路後，感覺就短許多，也許讓時間慢下來的祕訣，是尋找新鮮的體驗。
Confusion about Time
Dec 17, 2020
Lingyao Wu, a well-known writer, elaborated on the confusion of time in a humorous tone. She shared her view of "Is the speed of time a feeling? Or is it scientifically based?" in a fun essay.
When I was young, I liked to pretend to be mature, and describe time in an old-fashioned way: "Time is like an arrow, lifetime is like a shuttle, like white horses run across a gap, and the sunlight is flying by." In fact, I don't really understand the passage of years like an arrow. I still look forward to summer and winter vacation every day, also long for red envelopes. It feels like time is passing very slowly. Every wait lasts for a long, long time, just like Luo Dayou's "Childhood": "Waiting for the end of class, waiting for the end of school, waiting for playing the game, and wondering why the girl in the next class has not passed my window?"
Ten minutes of childhood can last forever, like a slowly moving train. I don’t know when it started. Time is like a thief, stealing our past. As we grow older, it suddenly becomes a fast-running express. The days disappear in the flash of God, and I can’t catch it, and it is getting faster and faster and out of control. It makes us confused about time. The passage of years is a topic that has been repeatedly mentioned in literature. Zhang Ailing once said: "A childhood that is as long as eternal life, living like years happily...then time accelerates and becomes faster and faster", which is mentioned in "Half Life" And: "Life flies so fast. For people after middle age, ten or eight years seems to be a matter of seconds."
When I get older, I am full of emotions about time being indifferent, and I send out an unanswered question: "where are the years?" I become old before I feel young, and my eyes get presbyopia before I take a good look at the world. It is said that youth is like toilet paper. It looks like a lot still left, but it is not enough for us to use. Some people think of time like a roll of toilet paper. When I was young, I just had a new roll. It took a long time to turn around. When I was old, it seemed to run out. When I pulled it, it was three or four turns and several years passed. Some people also compare time to a river, flowing from the distant past to the future, without stopping or going backwards. "Now" is just a point on the river of time, but it can never be caught.
Before people understand what time is, they have actually consumed half of it. Because of confusion, I have never stopped exploring time and space. Is the speed of time a sense? Or is it scientifically based? Einstein once used the theory of relativity to explain time. Sitting next to a hot stove, you will feel that time passes very slowly. If you date a lover, you will feel that time passes very quickly. David Eagleman, a professor of neuroscience at Stanford University in the United States, believes that the brain consumes more energy when processing novel things, records more memories, and learns new things every day in childhood, feeling that time flies very slowly. When I grow up, I am accustomed to the experience, and my mind does not see it being strange, and time will feel faster. Just like going to a new place, I always feel that the road to go is very long. After getting familiar with that road on the return journey, it feels much shorter. Perhaps the secret to slowing down time is to find a fresh experience.
The ancient Chinese myths and stories in "Journey to the West" mentioned this in many places: "One day in the sky, one year in the world." I asked my husband, who studied science, whether it was possible. He said it is possible. According to the theory of relativity, as long as the speed is fast enough, the time will slow down. He also remembered that he had taken 20 points for one question in the physics class in college, "According to this ratio, what is the relative speed between the coordinates in the sky and the coordinates in the world?" What a confusing question to me.
I thought of the story of the Cowherd and the Weaver Girl. The Cowherd, who lives on Earth, can only meet once a year on Qixi Festival, told the Weaver Girl about his lovesickness. But the Weaver Girl replied, "Don’t you know that a year on Earth is a day in the heaven?Seeing you once a day is just right. Wouldn't you feel annoying to meet each other every Earth day? If you didn't find it annoying, I'm annoyed." It can be regarded as a joke caused by confusion over time.
