1. Stardust
We are all stardust. from interstellar space. from nothingness. into nothingness.
I think this is the closest connection between ordinary people and the vast space.
Perhaps trapped in our self-made environmental barriers on Earth for too long, we have forgotten that the Earth is actually a large spaceship, and we are all sailing in interstellar space.
The first time I realized that the earth is a spaceship was one night, and I wrote this feeling in "The Rainy Season Has Not Come":
Baihedao, what do you see in the starry sky? I watch it often.
Shen Modao, Kant said, when we think about two things more often and repeatedly, they imbue people with constantly renewed, ever-increasing admiration and awe: the starry sky above and the moral law in the heart.
Bai He listlessly said, what does it have to do with me.
Shen Mo no longer reasoned with her, and dragged her away. Bai He was forced to watch the starry sky - the first time she saw such a starry sky, her eyes were full of stars, and multiple galaxies were connected into a strip of light in the sky.
Shen Mo taught him the correct posture to look at the starry sky. He turned his head back. What Bai He saw was not the starry sky, but the universe. The earth was like a huge spaceship, and he truly experienced that the earth was just a spaceship traveling through the universe. And himself, is the passenger who knows nothing.
Bai Hedao, isn't the starry sky I saw before this starry sky?
Shen Mo looked at the boundless starry sky and said, you are in the city, light pollution, air pollution, the starry sky you see is just the tip of the iceberg. You can't realize yourself at all, but you are on the earth spaceship, you will feel that the earth is the whole world, and even your city is most of the world. The most beautiful scenery often needs to go through hardships and obstacles to see. This is what I understood in high school. After a violent storm at that time, Yangguan passed through the clouds to form a strange halo in the sky, similar to the so-called Buddha's light, with colorful beams of light radiating to the surroundings.
Bai He said, have you ever seen Yao Chang Tian Mu Zhan?
Shen Mo said, what is it.
Baihedao, a kind of porcelain, seems to have three pieces in the world now, all in Japan. They call it the universe in a bowl. I saw a video introducing it, it was so shocking, I was shocked by porcelain for the first time. Just like the starry sky at the moment.
Suddenly I remembered that Van Gogh's starry sky turned out to be the real starry sky in the astronomical telescope now. There are black holes, there are rotating galaxies, and there are orbits between galaxies. Did Van Gogh already observe these? Or what you see in meditation?
2. Time and space
universe. Thinking from childhood to now, as Kant said: There are two things that we think about more often and more often, and they infuse people with constantly renewed and ever-increasing admiration and awe: the starry sky above and the heart the moral law.
But like turning on a light in the dark, what you see is just the tip of the iceberg, and more of it is darkness. The truth beneath the darkness remains unseen.
Thinking is ahead of observation most of the time. The curator of the ancient Egyptian library in Alexandria was really a genius. He calculated that the earth is round thousands of years ago, and calculated the circumference of the earth. I always thought that until the age of Magellan, no one discovered that the earth is round.
In modern science, theories are often ahead of observations.
Such popular science films should be watched by everyone, whether they can understand it or not. When you are in the vast universe, especially the multiverse, there is nothing you can't think of.
universe. The past is called the universe, and the four directions are called the universe. Nothing big, nothing inside.
Time and space are inseparable. The length of the meter is now defined as "the distance that light travels in a vacuum in 1/299 792 458 seconds".
Space is measured in time.
This is especially true in large-scale spaces. The light you see is coming from a star 13 billion light-years away, and the light you see is 13 billion years ago. And that star, at this moment (your time), may be long dead. Your moment is its then.
Whenever I think about this, I feel a little sad.
Yes, I once loved you, farther than this distance. 13 billion light years of loneliness.
The microscopic world (worlds much smaller than quarks) may be the same as the macroscopic world. The greedy snake bit its own tail. This popular science video confirms my guess. From the Buddhist point of view, big and small are inherently relative and can be transformed into each other. The so-called big is also small. So I wouldn't be surprised if the universe were a ring world.
The number of stars in the Milky Way exceeds my previous understanding, and the entire observable universe has more stars than I knew before. There are more grains of sand on earth. So it is impossible that there is only life on earth.
Human observation ability is really not good, and it is impossible to detect under the ice surface of Europa.
If the Big Bang Theory is right. Then in theory, if the observational power is sufficient, the Big Bang of the universe can be observed, and events more than 13 billion years ago can be observed.
The film optimistically predicts that in about 20 years, the origin of the universe may be found by simulating the Big Bang in a particle accelerator.
3. Light
Our existence is created by the universe to understand itself.
This sentence is great.
Light is indeed a magical thing, and many observations require it.
The universe, and even everything, is essentially no different from a fire.
Ignite, entropy increases, ashes.
Human curiosity drives oneself to obtain the origin of the universe and the unification of all things, but as Wang Yangming said, there is no end to knowledge.
However, if human beings really understand the answers to all questions, they will become gods, but they will have no curiosity and life will be boring. Therefore, Confucius said, “When you hear the Dao in the morning, you can die in the evening.” Now physics is not studying the principles, but really studying the Tao.
4. Alien life
After reading it, you will feel that the existence of life on earth is very luxurious. The existence of intelligent life is more extravagant. Life is also fragile. There are so many reasons for life to go extinct - supernova explosions, planetary comets hitting Earth, gravitational perturbations outside the solar system, abnormal solar activity... It's not ridiculous to worry. Humans are also very demanding on living conditions.
Whether alien life exists, I think, from the perspective of probability theory, it definitely exists. Because there are too many celestial bodies in the vast universe, it can be called infinite, so the probability of the emergence of life on earth is infinitely small. I agree with what Clark said, there is life in the craters of the earth, and there is life under the Antarctic ice sheet. Furthermore, the existence of life is not only carbon-based.
Why are there no traces of alien life yet?
A very important reason for personal analysis is the speed of light limitation. For example, even if there is a signal from life 1.5 billion light-years away, it will reach the earth at least 1.5 billion years later, and the signal received now is at least 1.5 billion years old. Furthermore, the level of observation is limited. Right now, we haven't figured it out in the solar system, and even if it exists outside the solar system, you won't be able to detect it.
Limitations of the speed of light or the laws of physics protect civilizations from war. This can be seen in the history of the world after the opening of new routes in human history. If you want to engage in interstellar navigation, you must break through the limitations of existing physical laws. At least now we have not found such a civilization that breaks the laws of physics. However, if the laws of physics are broken, it is estimated that people will not necessarily look at civilization on earth. Just like when you look at an ant, you don't bother to care about it.
Many years ago, Sakyamuni had seen through everything: all the dharmas that exist are like dream bubbles, like dew and like electricity, and should be viewed in this way.
It means that the world is like a dream bubble, just like a soap bubble. You think it is eternal, but to him it is like electricity and dewdrops. Blow up a bubble and quickly burst.
Isn't that what multiverseism is?
Shakyamuni smiled and said nothing.
