In order to make our lives more regular, we invented the calendar, which divided the year into 12 months, the month into about 30 days, the day into 24 hours, and the hour into There are 60 minutes, and one minute is divided into 60 seconds. Generally, we use years, months, days, minutes, and seconds to calculate time, but the great man Einstein once said that time is just an illusion. To prove this statement, NASA conducted an experiment.

First, an experimental subject was selected from 20 volunteers. The experimental subject was a 27-year-old Italian woman named Forlini, who was an interior designer by profession. Demonstrate strong self-discipline and psychological quality. Before the experiment began, NASA researchers also conducted a comprehensive physical examination for her, and then sent her into an 18-square-meter cabin in an "underground cave" about 30 meters deep.

There are also some books, guitars, and a computer that can communicate with the outside world in this cabin. However, there are no tools for timing, and the researchers also monitored Folini through cameras and microphones. , then regularly checks her blood pressure, heart rate, body temperature and brain wave patterns, as well as regularly testing her for hormonal changes. Experimental results.

The subject thought she had passed two months, but in fact four months had passed. The doctor also conducted a comprehensive physical examination on her and found that in the past few months, she had lost 7.7 kilograms in weight, was deficient in vitamin D, and had even stopped menstruating.

This experimental result shows that human beings will be under tremendous psychological and physical pressure in a claustrophobic environment, and it also shows that human beings cannot perceive time at all without receiving external information. Even previously normal patterns can change. Is time an illusion?

In fact, time is relatively elusive. There is currently no accurate expression of what time is. Einstein famously said: For us committed physicists, the distinction between past, present and future is an illusion. As the founder of physics, Newton also believed that time is just an illusion produced by human memory function.

In the eyes of scientists, time is a fixed quantity. For example, time will only flow in one direction. Anyone who wants to break through this direction and return to the opposite point of time flow will be disturbed by the universe and nature. Blocked by laws, we can never break through. What we need to understand is that no matter whether time exists or not, human beings' birth, old age, illness and death have their own natural laws. This is an unchangeable fact.
