However, if we want to analyze the allusion of this sentence, it is not the case. Let's take a look at the allusion first:
One day in the cave has been in the world for thousands of years. Many people think it comes from Yu's Zhi Lin in the Eastern Jin Dynasty: it tells the story of a farmer who went to chop wood and suddenly saw a stone house in the mountains, so he went in. There are two boys playing chess, and Wang Zhi stands by and watches. After the chess game, Wang Zhi found that the axe he used to cut wood had rotted. When he got home, the whole hometown had completely changed!
This story has appeared in many ancient books, but the characters and events are somewhat different. Some versions of the chess player are two immortals and some are boys, but this does not affect the development of the story, because the ending is the same: the axe is rotten and the hometown changes dramatically.
Some people analyze this. The woodcutter was watching chess in the cave, and time passed unconsciously. It's been many years since I played chess! But this analysis is unscientific. When he was watching chess, his appearance and age did not change. Only the axe in his hand changed, and everything outside the hole changed. This doesn't mean that time passes slowly in the cave.
If time passes slowly in the hole, won't the axe in his hand? Rotten? . So this story is just the fantasy novel of the ancients, but it wasn't when the author made up the story? Time difference? The concept of.
Understanding of Time Tunnel
Just visiting has only appeared in science fiction works, and scientific research is only in the theoretical stage.
Theoretically, it is gravity that affects time. According to Einstein's theory of relativity, gravity will slow down time. For example, if we enter a black hole with strong gravity, the time inside will pass slowly and will not appear until we come out of the black hole and return to the earth? A day in a cave has existed in the world for thousands of years. Phenomenon.
But this phenomenon only slows down the time in a certain area, and there will be no time-space crossing, because time will only go forward, not backward. It's just that the visit we often talk about is a tunnel that can go back to the past described in science fiction, but it's actually impossible.
For example: I am now entering a planet with high gravity, living there for a day, and then returning to Earth. At this time, the time on the earth has passed 100 years! For the earth people, I am a wearer, crossing from ancient times to the future; For me, this is just one day in my life. So even if there is a time difference, it is impossible to go back to ancient times.
label
One day in a cave, the idea of a thousand years in the world, is mistaken by some people for the idea that the ancients had a time difference, and that the ancients of that era had the idea of traveling through time and space, thus inferring that they were thousands of years earlier than Einstein's thought.
This view is wrong. The story of watching chess in the cave is completely similar to that of fantasy novel in Liaozhai, especially the description that the axe in his hand is rotten but the person is intact, which is completely inconsistent? Just visiting? The theory of.
