avity, we naturally can’t feel the earth moving at a high speed.
What happens to the earth when the sun suddenly disappears? The first thing many people think of is that soon the earth will fall into darkness and the humidity will drop sharply. Yes, this is what people living on the earth can see directly. When the sun suddenly disappears, it takes eight minutes for photons to reach the earth, so the earth will still have eight minutes of light. After eight minutes, no photons will reach the earth, and the earth will fall into darkness. It is the kind of real darkness that you can’t see. There are no stars or moon in the sky.
Then the temperature of the earth will drop rapidly. Soon, the earth will become a frozen planet. People can only live underground if they want to live. It’s just a small impact on the earth. In fact, the real threat to the earth is in space. When the sun disappears, the huge gravitational source accounting for 99.84% of the mass of the solar system disappears. What happens?
I believe many friends will think that the solar system may be in chaos. That’s right. When the sun disappears, the disappearance of the gravity boss makes the solar system free from strong gravity, and the eight planets and other asteroids are free without managers. At this time, the earth will fly out along the tangent of the orbit at the speed of 30km / s. Other planets and innumerable asteroids will also fly around. The collision events of celestial bodies in the solar system will occur frequently, and they will be smashed to pieces in many days.
At this time, the earth will not only face the disaster of the earth itself, but also face the threat of celestial body impact in space. If we are not careful, the earth will be hit by other celestial bodies or the earth will hit other celestial bodies. And the earth is so free of the constraints of the sun’s gravity, in addition to being thrown out, and the earth’s atmosphere will be instantly disturbed, many ground objects will fly into the mid air.
Some people may say that if the sun disappears, the solar system will be finished, and it will completely disappear into the universe. In fact, it is not. Although the disappearance of the sun will bring chaos to the solar system, all planets and asteroids will fly freely in a short time. But don’t forget, there is another planet in the solar system, Jupiter. The mass of Jupiter is many times more than that of the other eight planets combined.
When the sun disappears, Jupiter will be liberated. At this time, Jupiter will become the leader of the solar system. In the process of its high-speed movement, it will continue to attract nearby celestial bodies closer to it. As time goes on, the sky of the solar system will form a new operation order, with Jupiter as the center. However, the mass of Jupiter is far less than that of the sun, so its gravitational influence is limited. Maybe mercury, Venus, earth and Mars will revolve around it, and other planets are hard to say.
At that time, the celestial bodies far away from Jupiter might leave the solar system, especially the celestial bodies on the edge of the solar system. In the past, there was the sun, and they could also be bound by the solar gravity. But if the sun disappears, Jupiter’s gravity is not enough to affect that far range, so the edge of the solar system will also be lost, and the final solar system can only be regarded as a reduced version of the solar system, with Jupiter at the center.
However, Jupiter is not a star after all, it can’t emit light and heat, even after the sun disappears, it can bear the heavy responsibility of gravity, but the solar system will always fall into darkness. If the earth is lucky enough not to collide with other celestial bodies, it will eventually orbit around Jupiter and stabilize. Can we survive without the solar system? I’m afraid it’s very difficult.
At that time, the surface of the earth could not survive because of the extreme cold. Human beings could only build underground cities and live in the underground world. So is the fate of manki
