The universe is echoing and shaking – Kookmin Ilbo


This anecdote appears in Cosmic Connections, the first book of mass science published by the astronomer Carl Sagan (1934-1996). He was dining with a publications planner and a Polynesian restaurant in Boston, USA. "You will soon be asked to decipher important messages." Could it be a coincidence? In fact, he became a bestseller for the Cosmic Connection, and his successor, Cosmos, became a long-standing astronomical bridge connecting Earth and outer space. People love you more.

However, the person who received the "request to decipher the important message" would not be the only one. Many scientists who are shining like stars around the world are still struggling to gauge the order of the universe or to inform people about order.

Kim Sang-wook (48) can not be overlooked if someone who plays such a role in Korea is quoted. He is a professor of physics at Kyunghee University and has recently become a scholar familiar to the public, appearing on the television program Alleyshin 3 & # 39; (tvN). & Quot; Tremble & Reverberation & # 39; is a beautiful and lively scientific book published by him.

"The universe is shaking"

Let's start by talking about the title. Why did he mention the words "tremendous" and "echoing"? The reason is that these two keywords can explain the mechanism of the universe.

The author says, "The universe is shaking. All the stops are shaking." The problem is that this is not a literary investigation. The table in front of him and the books on the shelf are also in the Jeongkungdong movement. Observation with an electron microscope may give a slight vibration to everything.

When the vibration is long, it becomes a wave. The wave makes the world. All waves and sounds are waves. So why the word & # 39; eolim & # 39; in the title is side by side?

"Humans are echoing, we react with a lot of trembling in the surroundings … We want to be a person who responds to the trembling of others My echo is another shiver and I want to be rewarded with a new echo The humans are echoing and trembling so much" .

In & quot; tremendous & echoing & quot ;, such a beautiful and beautiful phrase leads easily. The author uses two keywords, trembling and echoing, like plot and fold, drawing a huge order of the universe.

It is a work that can feel intellectual pleasure if everyone thinks it is difficult, but it does not have many contents. It is thanks to the ability of authors to show complicated content in a literary style. The author wrote, "I wrote in the hope that physics would look human," and wrote: "I tried to tell physics through the feeling of the humanities." This goal seems to have been reached steadily. It is rigid and concrete enough that there is no doubt whether a scientist writes a question or not.

The stories in the book are not really fun. He has scientifically examined all types of Gotham theory that would be mentioned by famous thinkers of the East and the West. & # 39; What is the time? & # 39; & # 39; How many spaces is the space? & # 39; & # 39; Death is something, & # 39; & # 39; How does the world work? ….

Among these questions, the look of the death of the physicist is very different from that of ordinary people. "When we know the atom, everything in the world begins to look different," he writes. All that stands out is just a "meeting of atoms," then death is just a scattering of atoms. "An atom is immortal, so the birth and death of a human being is no different from the gathering and dispersion of atoms."

It is also striking that the reason the world exists. To explain why the world exists, we must explain the beginning of the universe. Physicists think there is a "starting point" for the universe, which is the big bang. However, this does not mean that the universe was born as it "hit" space. Before the Big Bang, there was no empty space in it. Why is the big bang theory compelling? This is the observation that the universe is constantly expanding. This result can be obtained by tracing the path of light that comes from the past. To answer the question, "Why does the world exist?" You should be able to explain why the big bang happened. The author concludes the story of this issue by introducing a phrase in Stephen Hawking's masterpiece (1942-2018), "The History of Time."

"If we find the answer to the question of why the universe exists, it will be the ultimate victory of human reason. Only then will we know the heart of God."

The world of science

Let us recall the observations of Albert Einstein (1879-1955). "God does not play backgammon." The essence of this statement is that everything has a set of principles. If so, is there a "specific future"? The problem is the chaos. There are complicated movements in the world that are difficult to predict. If so, is there no answer that humans can enjoy? Science is eventually a study of agnosticism.

In conclusion, we have a mathematical weapon. Science is "dominated by the rule of probability." If you play a & # 39; 1 & # 39; when you roll a dice, you can not understand why that number has come out, but you can see the possibility of a & # 39; 1 & # 39 ;. We can solve many difficulties with a simple add / drop system.

"Mathematics describes nature in an incredibly precise and efficient way … The physicist believes that even though he may find an alien, he can communicate in mathematics.I do not know if the universe is actually used in mathematics, or whether we can understand the world in terms of mathematics, but without mathematics there is no physics. "

The universe moves according to the formula. One day is 24 hours. One year is 365 days. If you drop anything on the ground, it drops 4.9 m per second. But there is no special reason for the appearance of & # 39; 24 & # 39; & Quot; & Quot; 4.9 & # 39 ;. The same holds true for other scientific laws. However, humans convey the meaning of something to the bottom of science. We think humans appeared in this world, extinction of dinosaurs and sharing of love.

The author wrote: "Humans give meaning to the universe without meaning and live." "Even though meaning is only a product of the imagination, it is human to live like this, I do not know what happiness is, but it is people who try to live happily." Man enjoys the meaningless universe with joy, enjoying the imagination he created in his system of imagination, so the human being is more wonderful than the universe. "The white paper of this book is that it attracts the world of science without being so cold.
