Gliese 581 is a red dwarf star and a variable star. Variable stars are stars whose brightness and electromagnetic radiation are unstable, change frequently, and are accompanied by other physical changes.
It is the unstable radiation of Gliese 581 that gives the night sphere a bright side, creating a desolate scene where life cannot survive.
Shen Cong flew leisurely.
Familiar with the stellar fire's perception and control of time and space, and immersed in his new vehicle body, he wants to transform his body into a field. Only such a body can withstand various dangers and blows encountered in the universe. .
The rest of the month passed in an instant.
Shen Cong has arrived at a distance of less than 0.1 astronomical units from Gliese 581. Even though Gliese 581 is only a red dwarf star with a mass smaller than the sun, a smaller volume, two degrees smaller, and a lower temperature, at such a distance, it can still I feel like my body is starting to get burned.
0.1 astronomical unit is equivalent to 15 million kilometers, which is approximately more than a thousand times the diameter of the Earth, and equivalent to fifty times the distance from the Earth to the moon.
"The surface temperature of Gliese 581 is more than 3,000 degrees Celsius, which is okay. The interior may reach tens of millions of degrees Celsius, and the corona layer is also hundreds of thousands of degrees." Shen Cong began to rotate around Gliese 581.
Even the most powerful star-level cosmic fire cannot resist the high temperature of tens of millions of degrees Celsius. But the surface temperature is only a few thousand, which is not difficult for the star-level cosmic fire. It can stay for a long time. Even if Shen Cong is The star class that has just evolved is still not afraid of the high temperature on the surface of Gliese 581.
Of course, when mining fire seeds near Gliese 581, you must make other preparations.
The activities of stars are very violent, such as flares, prominences, sunspots, coronal holes, as well as light spots, spectral spots, stellar winds, etc., which may pose threats. For example, the energy released by a flare can reach almost tens of billions at a time. A 100-ton hydrogen bomb exploded.
Such a terrifying energy burst could have engulfed Shen Cong even if he was caught off guard.
Therefore, he had to carefully observe the surface activity rules of Gliese 581, and then mine the fire seeds in a relatively safe and calm area.
What deserves more caution is the corona of Gliese 581. It is the outermost layer of this red dwarf star, but the temperature is incredibly high at hundreds of thousands of degrees Celsius. The inner chromosphere to photosphere drops rapidly. At more than 3,000 degrees Celsius, this is a very difficult to explain phenomenon.
To reach the photosphere and mine fire seeds, you must first pass through the corona.
…
Time flies like this and another half month has passed.
The surface activity patterns of Gliese 581 were basically mastered by Shen Cong. He marked out fifteen relatively safe areas on the simulated guide map.
The thickness and weak areas of the corona are also under control.
Then, cheer up.
Approaching the first area, the huge planet-like body kept maneuvering and changing its orbit, enduring the high temperature and falling into the boundless hot fireball. It was smaller than the sun, but to Shen Cong, it was still invisible. Thousands of Earths would be eaten by the huge planet at the border.
As the distance gets infinitely closer, the field of view that relies solely on light can no longer be observed. High-intensity light can destroy all spectra in the field of view.
Fortunately, Shen Cong has basically put aside the vision of light and is dominated by the active perception of fire.
At such a close range, in active perception, the space-time around Gliese 581 is close to the edge of being torn to pieces, and the distorted space-time is like a piece of crumpled paper.
The influence of stars on space and time is evident.
The distortion of space and time produces gravitational waves. Gravitational waves can extend infinitely. Gliese 581 can also produce gravitational waves, but the size of the fluctuations of gravitational waves is very small. If Shen Cong had not searched hard, he would not have been able to find out the gravity of Gliese 581. Wave. The size of this wave can be as small as one thousandth of the size of a proton.
"The navigation of star-level cosmic fire will be dominated by gravitational waves, and gravitational waves will be used to construct a topographic map of the universe, or a star map... I am not strong enough for the time being, and my perception ability is weak. When my fire is developed and matured, I can also make star maps to outline the universe!"
The universe is infinite, and without a star map, it would be difficult to find a loop.
He is now basically operating within a few dozen light-years around the earth, and he can still rely on observing stars for navigation. After he leaves a distance of tens of millions, or even hundreds of millions of light-years, he will no longer be able to rely on observing stars for navigation. Because at that time, a person A slightly smaller visual error will cause a distance deviation of countless light years.
Therefore, the perception of gravitational waves needs to be put on the agenda.
"It's too early to talk about gravitational waves now. I'd better collect fire seeds first and reserve enough fire grain resources before we talk!"
…
The corona is the outermost layer of the sun, and the outermost layers of other stars are called coronas.
Of course, in Shen Cong's name, the outermost layer of Gliese 581 is still called the corona. Anyway, they have the same properties.
The corona is very thin, but the temperature reaches hundreds of thousands of degrees Celsius, and the average temperature can reach 700,000. The average temperature of the chromosphere inside it is only less than 10,000, and the average temperature of the photosphere is more than 3,000. It is simply two different worlds. It is the most difficult to understand. What is interesting is that the corona is outside the chromosphere and photosphere, and further away from the center of Gliese 581.
Science is not enough to explain it, and Shen Cong cannot understand it either.
But this does not hinder his upcoming work.
"Distort space and time, fly on a curved surface, quickly pass through the corona, and prevent being burned to death!" Shen Cong already had a way to deal with it, and this was also knowledge gained from the memory of Phantom Wings.
Those star-level cosmic fires, in their early days, were also unable to withstand the high temperatures of the corona.
So they used the space and time that stellar fire can control to develop a flying method called curved flight.
This is an applied technology based on the principle of space-time distortion, which is difficult to explain in words. Like gravitational waves, they are physical rules at higher latitudes. Without the perception of space-time, it cannot be truly understood and applied.
The corona of Gliese 581 has a diameter of millions of kilometers. It uses short-term distortion of space and time to create a curved surface and can fly through the corona in a very short time.
At most it consumes some energy and will not be melted by the high temperature of hundreds of thousands of degrees Celsius.
boom!
Shen Cong, who was in the planetary state, stirred up the surrounding space and time, quickly distorted the surrounding space and time into a curved surface, and then used the curved surface to fly and crash into the chromosphere.
"hot!"
“Too hot!”
"It's so hot!"
After entering the chromosphere, the surroundings are filled with charged particles moving at high speed. Each particle has high energy. Hundreds, thousands, thousands of charged particles hit Shen Cong, instantly ionizing his body. A dazzling blue arc is formed on the surface.
The ionized surface layer, thus inactive, was peeled off from his body by the corona.
So Shen Cong added that the corona ionization stripping continues this process until the curved surface flight ends, and it has gone from the corona layer with a high temperature of hundreds of thousands of degrees to the chromosphere of more than 10,000 degrees.
The ionization phenomenon no longer occurs, and Shen Cong does not need to consume energy to maintain it.
Everything returned to calm.
The real star of Gliese 581 was displayed naked in front of Shen Cong. The turbulent high-temperature gas was rolling and high-concentration radiation was overflowing. This was a world of unspeakable light.
