Preamble:
The Sun is one of the most important celestial bodies on the planet we live in, and without its illumination, the Earth would become an icy planet. The sun is also the source of energy for all life on earth, it provides us with warmth and light, and it can be said that the sun is one of the most important beings in our lives. But what kind of existence is the sun, and how much do we know about it? Today, we are going to talk about the sun and its dark side.
1. The dark side of the sun.
"The sun goes out", for many people, this is simply a big joke, how can the sun go out? It is so brilliant, so dazzling, there will be no day when it goes out. But, in fact, no matter what kind of thing, it has its lifespan and life cycle, and the sun is no exception. Although the sun still has a long life to go from now, it will indeed go out one day and become a "dead" star.
The sun isn't always so brilliant and dazzling. In the science fiction novel "The Three-Body Problem", there is a scene that is mentioned, that is, the sun is dark. When the sun is really extinguished, what will it become? I believe that many people will think that after the sun is extinguished, we should feel the darkness immediately, right? However, in fact, even after the sun is extinguished, we will not feel the darkness immediately, but there will be a long "transition period".
According to the research and calculations of scientists, after the sun goes out, the life on the earth can last for about 300 million years, that is to say, after the sun goes out, the earth will have a long "transition period", in this process, we can still feel the light and heat of the sun, but its brightness and temperature will be lower and lower, until finally, the earth will become a world without light.
From Earth, the sun was extinguished a long time ago, but we are only now feeling its darkness. This is because it takes time for light to travel, and the sun is a certain distance away from us, so when the sun is actually extinguished, it takes us 8 minutes to feel it.
When the sun goes out, what does the real sun look like when it's dark? Actually, it's like the starry sky we see at night, but the light pollution on Earth makes it difficult for us to see it for what it really is. However, at the beginning or end of the month, we have the opportunity to see the real sun dark without moonlight.
2. The dark "transition" of the sun.
The sun does not go out for no reason, it goes through a very long process, and from now on, it still has a long life to go, and during this life, it will always maintain a normal state of light and energy. According to scientists, the sun still has about 5 billion years of normal luminescence from now, that is, during this time, it will remain forever
