Preamble:
With the continuous development of science and technology, human exploration of the universe is also getting deeper and deeper, and the sun, as the star of our planet, has always attracted the attention of human beings. If something goes wrong with the sun, the impact on the earth is also very huge.
Recently, some scientists have discovered an anomaly, that is, the sun's luminosity is gradually increasing, and there is also a change in the spectrum, what is going on? Does it mean that the sun is about to go out? If the sun really goes out, what will be the impact on the earth? Next, let's take a look at it.
1. The process by which the sun goes out
From a scientific point of view, the extinguishing of the sun does not happen overnight, but requires a rather lengthy process. In fact, from the moment the sun produces photons, the path of photons becomes very unstable, because they collide with charged particles and change their direction. So, after passing through layer after layer of medium, the photon can finally escape the gravitational range of the sun. Therefore, once the amount of photons produced inside the sun decreases, then the luminosity of the sun will decrease accordingly.
During the propagation of sunlight, the collision of photons with charged particles causes the frequency of photons to change, which ultimately affects the color of photons. So, as the sun's energy decreases, the frequency of photons decreases accordingly, causing the sun's color to gradually change from blue-violet to white and finally red. And when the sun's luminosity decreases to a certain extent, the earth can feel the influence from the sun.
2. The impact of the extinguishing sun on the earth
Once the sun goes out, the earth will be plunged into a very long period of darkness, and it is very likely that it will fall into a state of extreme cold. Because the Earth's atmosphere can indeed remain warm to a certain extent when the sun's luminosity drops, but over time, the surface temperature will still drop dramatically, and it may eventually drop to near absolute zero.
Before the sun goes out, the sun's luminosity is actually gradually increasing, so the earth is also exposed to more intense solar radiation. This causes water to evaporate from the Earth, causing the atmospheric system to collapse and rocks to weathering at a much faster rate. Eventually, the Earth's surface may become like Mars, and at that point, the question of whether humans will be able to survive will be a big problem.
Epilogue:
Through the above introduction, I believe you have a certain understanding of the extinguishing of the sun and its impact on the earth. Although the extinguishment of the sun will indeed have a very huge impact on the earth, we should not worry too much, after all, the technology is very advanced now, or before the sun has problems, human beings have enough ability to find a new home.
