There is only one tree in the world that is still in China!A "treasure tree" that existed during the glacial period in the fourth season. It should have been extinct long ago, but there is still one tree in the Shandong countryside of China. Descending dragon tree, its whole body is full of treasures, and it can be used in medicine. For thousands of years, it has been used to drive away evil spirits and avoid poison for the villagers in this area.
It has survived for thousands of years, and the tree is now also an aging dragon clock.
Leonardo da Vinci: Ah, the Time Eater.
The author is Quedo. Tonelli, an Italian particle physicist, is a professor of general physics at the University of Pisa. He played a key role in the discovery of the Higgs boson God particle. The book was translated by Wang Lie.
Li Miao, winner of the Wenjin Prize in China and a famous theoretical physicist, reviewed the full text and recommended it as a preface.
Since the birth of Stephen Hawking's "A Brief History of Time", this book has been a poetic and cutting-edge truth of time for decades, leading us to explore the nature of time with irresistible beauty.
1. The story of time.
Time was created at the same time as space 13.5 billion years ago. In the universe, time and space belong to one and the same, and the opposite relationship is one and the other. People's memories and dreams are all temporal. Memory, in particular, is mainly a record of our past events.
Newton once said that time is an absolute, eternal concept, which is equivalent to the introduction of metaphysics.
It was strongly opposed by Leibniz. After the advent of Einstein's theory of relativity, people knew that space-time is distorted, and time is also innumerable, local time, not eternal.
In ancient Greek times, Plato's description of time was that it existed in imperfect, decaying things.
For example, fruits, from the beginning of flowering, long leaves, small fruits grow, and then to maturity. and finally to rot. A series of processes allow people to clearly see the traces of time.
To study the nature of time is to explore the origin of the universe. Time is divided into past, present and future. The universe is vast, and in the universe we see through astronomical telescopes, we can see countless billions of stars in a large area covered by our fingernails. Such a long distance, at the same moment, has lost its meaning here.
The concept of time is already present in the genes of the object. For example, a mimosa plant, it will consciously separate, the concept of 12 hours of day and night. Even if it's locked up in a dark room. It is with the concept of time that the ants will stock up on food for the winter. Otherwise, you can only wait stupidly and freeze to death.
2. Can time be reversed?
Time seems important to humans, but in the vastness of the universe, time can even disappear. Especially around a large number of black holes, space-time will be torn apart. Spend a few hours around a black hole and humanity will pass centuries.
As far as we know about black holes, a small black hole will contain more than 30 suns. The star Ax Sagittarius has a mass of 4 million suns. J2157 has a mass of 34 billion suns.
These black holes are very massive, and when the mass is too large, it absorbs everything around it, and space-time disappears here.
Of course, time is going to disappear, and it doesn't happen on Earth. The true reign of time is the earth of mankind.
Around a black hole, time passes, and of course it can't be reversed. For example, the time crossing that is very popular in TV dramas now is impossible to achieve. Even the use of positive and negative electrons in the positive and negative electron accelerator is only to return to the original state, and cannot make a difference.
Objects are made up of a huge amount of particles. For example, a grain of sand has hundreds of billions of particles. The composition of objects is so complex and delicate that it is impossible to travel through time.
Time and entropy can only move forward, not backward. Entropy forward means that things are going to be ruined and detracted.
In turn physicists have proposed the end time. It's like what we see in TV dramas, or the end of time in cartoons. Doraemon has time to terminate the machine.
To this end, scientists have proposed string theory and circle quantum theory, which are still immature and have not been experimentally verified.
3. People's lives are controlled by time, so how to change the past?
Rembrandt also painted a number of self-portraits to document the changes in his appearance at each stage of his life. Many wealthy businessmen wanted to buy his paintings, but he refused.
The great painter Vermeer painted a series of famous paintings, especially the girl with a pearl earring, who was very famous. Through a series of paintings, he changed the past. Let people remember the past clearly.
The great ** Debussy created the "Prelude to the Afternoon of the Faun", which adapted the combination of notes, blended time, and made people sound refreshing.
People feel comfortable with stable and harmonious **. But there are also five notes that create a crushing devil**, known as a 4th degree. These notes are all unstable ions, and they decay very quickly.
It is now possible to divide ions into 13 types, just like the 12 main gods in Western mythology. Time is known in Western mythology as the god Kloros.
Most of these ions have short lifetimes, such as minus 25 seconds of ten. But the electrons and protons in it are immortal, and the lifespan of the Shenzi proton is 10 to the 33rd power of years. The lifetime of an electron is 14 10 to the tenth power.
In other words, the electrons circulating in the wires in our homes contain the electrons from the birth of the earth. The constituent elements of our fingers also contain ions from the beginning of the universe.
The painter's precise description of time is Dalí's series of melted clocks. The clocks and watches are distorted, which is actually a description of the distorted space-time phenomenon in the universe.
Time is the most merciless sentient being. Whether you're a rich man or a celebrity?There's one trick you'll look old. You're all going to die, too.
Even if you have a thousand-year-old iron threshold, you will eventually need a soil steamed bun. Everyone has to have that handful of soil after they die. No one will be much more than the other.
The fairest place in the world. It is also given by time.
