I believe everyone is familiar with the sun. It is a star located in the center of the solar system, and its mass accounts for 99.86% of the entire solar system. The powerful mass makes it the boss of the solar system, relying on gravity to bind the eight planets and a large number of asteroids.
The sun is equivalent to the needle of the solar system. With it, the entire solar system will be very stable, and the eight major planets will orbit each other in a stable orbit. From the outside, the sun is a blazing fireball. When human beings first entered the age of technology, they didn’t know what kind of pattern the sun’s burning belonged to.
With the continuous advancement of human science and technology, we know the two modes of nuclear energy, and then we know that the burning of the sun is nuclear fusion, a more advanced combustion mode. The energy produced by nuclear fusion in the center of the sun is continuously released through the surface and reaches every corner of the solar system.
The energy of the sun is very powerful. The light and heat released at every moment are far beyond our imagination. So how high is the temperature of the sun’s surface? According to current observations and studies, the average temperature on the surface of the sun is about 5,500 degrees Celsius, while at the core, the temperature can reach 15 million degrees Celsius.
Such a high surface temperature also hinders mankind’s exploration and understanding of the sun. To know that we want to truly understand the mysteries of stars, it is far from enough to rely solely on remote detection. The reason why mankind knows so much about Mars is precisely because our probe has landed on the surface of Mars and observed the Martian environment at close range.
In the same way, if we want to truly understand the sun more comprehensively, we must walk into the sun and climb onto the surface of the sun. Moreover, scientists believe that stars, as a ubiquitous celestial body in the universe, play a key role in the evolution of the universe after its birth.
The star is by no means the simple nuclear fusion as we currently know it. Its mystery is far more complex and mysterious than we thought. Humans’ current understanding of the sun can only be regarded as a fur at best, and even for some conditions on the surface and inside of the sun, what they currently recognize is not necessarily normal. The real surface of the sun may not be what we imagined in the past.
If we want to truly understand the situation on the surface of the sun, then we need to enter the sun and truly reach the surface. But in the face of a high temperature of 5500 degrees Celsius, how do humans do it? Or what kind of substance is needed? We must know that the high temperature of more than 1,500 degrees Celsius is enough to melt steel, and the high temperature of 5500 degrees Celsius can melt almost everything on the earth.
Theoretically speaking, there is nothing on the earth that can withstand the high temperature on the surface of the sun, and we must not forget that the temperature on the surface of the sun is not high enough. Before reaching the surface of the sun, we need to pass through the corona, which is the outer layer of the sun’s surface. In one of the structures, the temperature reached 1 million degrees Celsius.
What kind of material can resist the temperature of the corona and reach the surface of the sun? I believe that this material does not currently exist, and it is unlikely to have it in the future. Scientists speculate that even if human technology goes further, it is unlikely to develop materials that can withstand the high temperature of millions of degrees Celsius.
Even at a high temperature of 5,500 degrees Celsius, the materials on the earth are completely unstoppable. At present, the metal with the highest melting point is tungsten, which reaches 3410 degrees Celsius. And tungsten is not the substance with the highest melting point. The substance with a higher melting point is a non-metallic material, reaching 3820 degrees Celsius. This substance is graphite that we are very familiar with now.
Through artificial synthesis, humans have now produced a hafnium alloy with a melting point as high as 4,215 degrees Celsius. Even so, this temperature is still some distance away from the temperature of the sun’s surface, let alone the temperature of the outer corona. Aircraft made of this material cannot reach the surface of the sun at all.
Could it be that human beings can never reach the surface of the sun if they can’t research a material that can withstand the surface temperature of the sun? Here we have to mention a phenomenon in the core of the earth. I believe friends all know that the temperature of the core of the earth is also very high, reaching 6000 degrees Celsius, which is higher than the temperature of the sun’s surface.
But there is a solid iron core in the center of the earth’s core at such a high temperature. What is going on? What kind of material can not melt at a high temperature of 6000 degrees Celsius? In fact, there is nothing special about the iron core material in the center of the earth. It is a high-density sphere composed of iron and nickel. If it is in other environments, it cannot withstand thousands of degrees of high temperature.
But the pressure here in the core is 3.5 million times the atmospheric pressure on the earth’s surface. This is an extreme pressure environment. Under this pressure environment, the melting point of the material is very high. It can be seen that under an extreme pressure environment, substances can withstand very high temperatures.
In addition to the high-pressure environment of the earth’s core that can maintain the solid state of matter, humans are currently studying and exploring controlled nuclear fusion, and using magnetic fields to constrain high temperatures is also a good research direction. We must understand that to ignite controlled nuclear fusion, a high temperature environment of at least 100 million degrees Celsius is required. Such a high temperature cannot be restrained by any material. What should we do?
If you want to rely on materials to achieve controllable nuclear fusion, perhaps humans will never be able to make it a reality. No matter how hard we try, this kind of high temperature resistant material may not be realized. At this time, scientists thought of magnetic fields. The magnetic field is a very powerful force. The sun is so violent but it did not explode and fell apart. It is precisely because of the restriction of the powerful gravitational field that this super gravitational field is brought about by the huge mass of the sun itself.
At the end of the sun, the sun will expand and transform into a red giant star, and finally the outer shell will break away, because as the hydrogen fuel is consumed, there is no strong gravitational field restraint, and the outer shell is no longer stable and gradually separates. Field also belongs to a kind of matter, although it is invisible and intangible, it can be said to be a powerful intangible matter. This invisible field is sometimes so powerful that we feel incredible.
Scientists have observed the entry and exit of unknown objects on the surface of the sun, and speculated that it may be a spacecraft of an alien civilization. When these unidentified objects are observed close to the sun, a protective cover will light up around them. This protective cover may be a gravitational field to resist the high temperature on the surface of the sun.
In theory, we can also create such a gravitational field to wrap it around the spacecraft and resist the high temperature on the surface of the sun. The strong gravitational field can restrain the high temperature of hundreds of millions of degrees Celsius, and the temperature of this point on the surface of the sun is naturally not a problem, even the temperature of the center of the sun is only 1500 degrees Celsius.
If humans can study this kind of gravitational field and install it on a spacecraft, then the sun will become our back garden, allowing us to enter and exit at will. At that time, all the secrets of the sun will be revealed by us. Uncovering the secret of a sun basically unlocks the secrets of the stars of the universe, which is of great significance for us to understand the evolution of the universe.
Materials science is a science that is very difficult to break through. At present, we do not know whether there are materials that can withstand the high temperature of stars in the universe. If not, then humans cannot rely on science to produce stronger high-temperature materials. Without strong high-temperature materials to enter the sun and reach the surface, they can only rely on the constraints of the gravitational field.
The theoretical research and exploration of the gravitational field is much easier than the research and exploration of high-temperature materials. At present, we know that the powerful gravitational field can be restrained even in the high temperature environment of nuclear fusion of hundreds of millions of degrees Celsius, not to mention the temperature of 5500 degrees Celsius. On the contrary, it is a material that can withstand the high temperature of 5500 degrees Celsius. We have no research direction at present.
