Living in the solar system, we have access to too many convenient conditions, because of the right light and temperature, the earth can give birth to life. Similarly, if human beings do not upgrade science and technology in the future, the subtle changes of the sun will also affect our life and death.
Due to a series of problems such as the high temperature of the sun and the distance between the earth and the sun, we know far less about the sun than other bodies in the system. Scientists have tried to study the sun in depth with the help of advanced detectors, and in the process have made amazing discoveries.
<> there were many loopholes in the objections that alien civilizations drove spaceships to the solar system to "refuel". For example, the distance in space is often light-years, and we still have no traces of the existence of other advanced civilizations in the solar system. If they were from other galaxies, they would have broken through the speed of light, and it would take years to fly to the solar system, just to "refuel", but it was not really cost-effective.
At the same time, some scientists believe that it is not easy to "refuel" the sun, and if a large amount of energy from the sun is absorbed, there will be obvious changes, and we will not be unnoticeable. However, in recent years, the phenomenon of abnormal solar activity has increased, and it is understandable that people have misjudged.
The mystery of the sun cannot be solved in a short time, and it will be a very important initiative for us to be able to get to the vicinity of the sun for research, and we need to continue to work on it. As for the claims about extraterrestrial civilizations, we cannot deny their existence, but we cannot find direct evidence of their real existence, so we can only dismiss them as fanatics of alien fanatics.
The sun is very important to humanity, and we will need to study it in depth in the future. Gaining more information from the changes in the sun will help mankind unravel the mystery of the birth of life, and may even help us fly out of the solar system as soon as possible to explore a wider cosmic space.

No, the mysterious objects that appear near the sun are not solar-powered spaceships, but some relatively ordinary cosmic fragments.
-
These mysterious ships don't have a good definition yet. But the universe is so big, it is impossible for only the earth to have life, and perhaps there will be more advanced beings on other planets.
-
In the vicinity of the sun, it is possible to use solar power for spacecraft, and at that time human spacecraft will not be able to use the solar energy for fuel.
-
The sun is a perseverance, but also the boss of the solar system, firmly attracting the celestial bodies of the solar system, so that they run in a regular manner, the life of the earth is inseparable from the light and heat emitted by the sun. The light and heat emitted by the sun are actually released by the continuous nuclear fusion inside the sun, which is also a very powerful energy source, and it is an energy source that human beings yearn for.
If it weren't for the material ejected from the sun itself, there was only one explanation, these asteroid-sized unidentified objects were likely to be spaceships, and this news aroused the interest of many astronomical enthusiasts, most scholars believe that this must be an alien spaceship, but what are they doing close to the sun?
These unidentified objects slowly approached the sun, and then formed a circle of light, enveloping the sun in it, and the surface of the sun fluctuated violently, which is very similar to these spaceships collecting the sun's energy, this kind of thing is not only recently, once Russian probes also found huge unidentified objects near the sun, but also stayed near the sun for a while and left.
Last year, U.S. probes also found a huge unidentified object near the sun again, and after comparing it with the unidentified object observed in Russia in the previous period, scientists believe that the unidentified object that appeared twice is actually the same spacecraft. If they are really alien spaceships, then the strength of this alien civilization is too strong than that of human beings, and the light energy is safely close to the sun and absorbs the sun's energy, we are very envious, and the spaceship of the key people is as big as an asteroid, this technology is unimaginable for human beings.
Scientists suspect that the advanced civilization in the universe has actually discovered the solar system and discovered the earth a long time ago, but it may be that the civilization level is too different, and the aliens are not willing to contact and communicate with human civilization, but the solar system has absorbed some of the sun's energy every few years, and it seems that the civilization level of human beings is too low, and if you want to talk to aliens, you can't do it without considerable strength, and it can also be seen that this alien civilization is still relatively friendly, and it doesn't want to contact with humans and doesn't invade the earth.
If you encounter a malicious alien civilization, see a living planet like the earth, and the disparity in strength is too great, once the aliens invade the earth, human beings will have no power to resist. Only when human beings strive to develop science and technology and continuously improve the level of civilization can they be truly safe, can they come into contact with those high-level civilizations in the universe, exchange and learn from each other, and can civilization progress faster.
-
No. Because there are no aliens in the universe, the unidentified objects that often appear on the surface of the Sun are not alien spaceships.
-
I don't think so, it's probably just a dark spot of the sun, you have to believe in science, aliens haven't been discovered yet.
-
We can also see this unidentified object from another spectral map of different colors, and we can be sure that it is drilled out of the sun, and it is difficult to observe this unidentified object if it is not at a certain angle.
In fact, this is not the first time that unidentified objects have appeared around the sun, and some unidentified objects have appeared in many suns earlier, and NASA has not explained anything, but many UFO research experts and astrobiology scientists believe that these unidentified objects around the sun are likely to be the spaceships of advanced civilizations in the universe, and the purpose of their orbiting around the sun is to use the sun to replenish energy, and obviously these civilizations can already use stellar energy.

There is a gravitational force between every object with mass, the greater the mass, the greater the gravitational pull, and the farther away the gravitational pull, the less gravitational pull. The sun is the celestial body at the center of the solar system, and the sun accounts for the mass of the entire solar system.
In fact, relative to the earth, the gravitational force of the sun can suck the earth at such a close distance, but because the major planets have an angular momentum at birth, the gravitational and centrifugal forces between the central star and the planets have achieved a perfect balance, and in the absence of resistance in space, this balance will continue forever, so other planets, including the earth, will not be sucked over.
The solar system has also survived in the universe for five billion years, and all celestial bodies that do not meet the equilibrium standard are naturally eliminated, and the remaining celestial bodies are naturally balanced by the sun'......s gravity and their own centrifugal force
-
The magnitude of the gravitational force can be calculated from the formula, in which the magnitude of the gravitational force is directly proportional to the mass of the respective object and inversely proportional to the distance between the two, in addition, the gravitational force is not only magnitude, it also has direction. As mentioned earlier, the mass of the sun accounts for a very high proportion of the solar system, which proves that its gravitational effect on other stars is also very large. In fact, there are two main reasons for this, one is that the distance between the sun and many stars is as high as tens of billions of kilometers, resulting in the gravitational effect of the sun on the stars is greatly reduced, but the gravitational force is still very large; The second is that other stars revolve around the sun, which requires a centripetal force, and gravity acts as a centripetal force, which is also the fundamental reason.
-
And how many people really understand gravity? The gravitational pull of the sun can act on objects tens of billions of kilometers away, this is a big joke, the sun is constantly rotating from the inside to the outside and releasing a large amount of positive energy to form fire and temperature, distributed in its 300 million kilometers of time and space, some energy is composed of matter, all matter on the planet has gravity, gravity is the combination of matter and gravity, the sun does not have gravity, because the sun is not a substance, no matter can withstand the high temperature of hundreds of thousands of degrees of the sun.
-
Because according to the law of gravitation, there is a gravitational force between any two objects, and the greater the mass and the closer the distance, the greater the gravitational force between them, and the sun is certainly no exception.
-
The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".
-
The range of the sun's gravitational pull is infinite, so objects tens of billions of kilometers away are also within its range.
-
Because the gravitational pull of an object in the universe is that the farther away it is, the greater the gravitational pull, so even if it is tens of billions of kilometers away, there will still be a gravitational force.
-
What does it take for humanity to break free from the gravitational pull of the earth now? What humans need to get out of the grip of the Earth's gravity is energy. Energy is the guarantee against all gravitational pulls. All gravitational pull is generated and controlled by energy.
-
Spacecraft, space shuttles can use solar energy.
There is an envisaged propulsion that uses solar sails to propulsion using the sun's light pressure.
Although the thrust is not large, there is almost no resistance due to the cosmic vacuum. It can be accelerated all the way up to a very fast time.
However, the photoelectric conversion efficiency of existing solar panels is too low to realize large-scale conversion, and the technical limitations determine the application limitations.
-
The reason is that the masses of the two interacting objects are large enough that the gravitational force is directly proportional to the product of mass and inversely proportional to the square of the distance.

After the universe was large, physicists discovered four fundamental forces in the universe, gravity is the weakest of the four fundamental forces, but its range is infinitely <>
Newton in the 17th and 18th centuries was the first to summarize the phenomenon of gravity, and he proposed the law of gravitation, which states that the more massive the celestial body, the stronger the gravitational force, so it will "attract" the small mass object to it, which is why the apple falls to the ground instead of flying to the sky, but because the planets in the solar system rotate very fast, the "centrifugal force" generated and the sun's gravitational force just reach a balance, so the earth does not fall into the sun.
After the law of gravitation appeared, the astronomical community used it to confirm the existence of Neptune and to ** the phenomenon of solar and lunar eclipses very well, but as time passed to the late 19th and early 20th centuries, physicists began to discover the limitations of the law of gravitation. <>
As the closest planet to the Sun, Mercury's perturbation data at perihelion do not match the data calculated by the law of gravitation, and in response to this problem, theoretical physicist Albert Einstein proposed the general theory of relativity, which can be regarded as an upgraded version of the law of gravitation.
The general theory of relativity believes that the universe is an elastic place, and celestial bodies with different masses cause different degrees of distortion in space-time.
No matter how small the mass of the celestial body is, it will also press a depression on the space-time film, and this depression will not disappear, it can act on infinite distances, but the intensity will also decay rapidly. <>
A tank full of water, even if a stone falls into it, will make the water surface rise slightly, and no matter how small the mass of the celestial body in the universe and space-time, it will also make the space-time slightly distorted.
-
This is the law of gravitation proposed by Newton, and it is well known that the reason why apples fall to the ground is because of the gravitational pull of the earth, because the sun has a much greater traction force than the earth, so it can attract objects so far away.
-
All objects are attractive, but the sun is very large and massive, which makes it relatively more attractive to objects and can extend far away.
-
The gravitational pull of the sun can act on objects tens of billions of kilometers away, which can be used by the mutual forces in the universe, one of which is the gravitational force proposed by Newton, and the universe is a mixed space, and the universe must also have gravity, and the sun can naturally act on other objects.
-
Because the sun is a very energetic object, and it can also emit light, gravity can drive hundreds of millions of kilometers of objects, which is the mystery of the sun's gravity.
-
The gravitational pull of the sun can act on objects tens of billions of kilometers away because the gravitational pull of the sun itself is strong enough, and the gravitational strength of a star is related to its own mass, and the mass of the sun occupies the entire solar system, and its own gravitational attraction is of course very strong.
