It is said that tens of millions of years ago, it was precisely because a great ape began to look up at the stars that human civilization got its budding spark. I have been full of fantasies about the vast universe and the sky full of stars since I was a child. When I reach middle age, my passion is gradually buried by the trivial matters of daily necessities. Today, I have been captured by the book "What does this universe have to do with me?" 》and ignited.

This popular science book written by the famous theoretical physicist and astrophysicist Harald Lesch of the University of Munich in Germany is currently selling well in many countries around the world. What is the universe like for us humans, and what is its relationship with our species or each individual person? Is it the "dark forest" full of dangers described by Liu Cixin ? Or is it the absurd and oracular realm described by Arthur Clark ? This "tour guide" manual of the universe carefully led me on a "root-seeking" journey spanning tens of billions of years.

1. The magic of chaos and order - everything is accidental

"All seemingly unreasonable existences are possible in the universe." Astronomy has developed for thousands of years and has now developed into applied astrophysics , already represents the highest level of technology. Based on the information we continue to collect, we have measured the temperature of the universe, "seen" the cosmic background radiation, and learned that elements such as carbon, oxygen, calcium, sodium and potassium that are essential for our bodies come from the universe. The nuclear fusion process of the furnace.

When we breathe, drink water, and move around, we need to take in substances from the outside world and at the same time release substances. My body is combined with these substances in the universe and relies on the continuous supply of these chemical energies to continue. The universe has natural laws that apply to the entire universe, and as we gradually realize these laws through physics, we find that our existence is so accidental.

The solar system happens to be located in the "green belt" of the Milky Way . Our sun happens to be a "mild" star. At the beginning of the formation of the solar system, the two migrations of Saturn and Jupiter helped the earth sweep away the harmful effects on life. Most of the obstacles to evolution created the right conditions for the birth of the Earth and continue to protect it to this day. A planetary impact of just the right mass and timing to bring us the moon stabilized Earth's own wobbly spin axis. At some point after the earth cooled down, comets and happened to bring water, and the appropriate distance between the earth and the sun and its own large enough mass happened to remain in the "too cold" and "too hot" range to breed life. In delicate balance. Thus, the laws of nature and all chance blended together to create our earth.

"A huge metamorphosis took place on this planet - dead matter became living matter, and life was born in death."

2. Past, present and future - astronomy is the actual archeology

Laozi said: One life is two, two begets three, and three begets all things. The space where known life currently exists is a three-dimensional space, and time is presented in three forms: past, present and future.

"When we look up at the sky, we are actually looking back at the past."

When we look up at the starry sky, what we actually see is a panoramic view of time that depicts the "past" of each period. A massive star 6,000 light-years away from us exploded, and it would take 6,000 years for us to receive radiation information related to it. We deduce our energy trajectory through every past period we can "see". How did we become who we are today? We have a special ability: we compress time. We live in an era today where more and more technology and pressure are compressing our time. What used to take hours now takes minutes. All time has become "now." The universe we live in is a network composed of time, space and objects that move and change in it.

What is our relationship with the universe? “We are one of the results of evolution that goes back in time to ancient times."We have always been successful in being retained, inherited, further networked and further optimized in our "tests". “We have three tenses in our thinking: past, present and future. “We humans are the result of the ongoing interplay between supply and demand. "Seeing these answers, my heart inexplicably gained some confidence in life.

At the end of the book, there are two most tender paragraphs, which also brought me into that confused and deep thinking.

"One kind of relationship with all things The feeling of connectedness often overwhelms us. Even a tree that provides shade on a summer day points to the universe with every leaf. "

" Someone said: In space, you will be very calm, very gentle and very tolerant when facing yourself and other people. "This is because, there, in the darkness and void of the universe, there is our happiness. This happiness is that we can be on the earth."

We are all children of the universe, and this is a very happy thing.
