I Have a Little Black Hole

If the sun from Earth looks like a hot little disc at noon, and looks like an enlarged duck yolk in the morning and evening, then looking at the sun on Mercury, the closest planet to the sun, would be What does it look like?

It can be heard from Lei Tiantang's pretentious emotion now. Because the distance between Mercury and the sun is the closest in the entire solar system, it is natural that the sun will be much larger on Mercury than on the earth. It is not wrong for Kuafu to complain that he is talking nonsense.

In fact, the size of the sun as seen on other planets will of course be inversely proportional to the planet's distance from the sun. Earth is 1 AU from the Sun, while Mercury is 0.387 AU from the Sun.

Then the size of the sun on Mercury is 1/0.378 = 2.645 times that of the earth, and then calculating this number with pi, you will get 8.31 times the number, so looking at the sun on Mercury should be looking at the sun on the earth more than 8 times.

But because Mercury has no atmosphere, it doesn't scatter sunlight. Therefore, although the sun on Mercury is very large and the sunlight is very strong, because there is no atmosphere, it will not scatter and refract sunlight. The sky on Mercury still looks dark, just like the color of the night sky of the earth, and the place facing away from the sun is still dark. Can see stars.

Therefore, the pretentious remarks behind Lei Tiantang are still nonsense. It would be hell if he could still see the stars facing such a big sun!

Although the company has put a total of two probes into the orbit of Mercury, Lei Tiantang and the others put a lot of probes into the solar system during their last voyage to Mars, and of course Mercury also has them here.

A total of 12 probes that flew to Mercury finally successfully entered the orbit of Mercury, and 9 of them successfully entered the orbit of Mercury. Both Lei Tiantang and Kuafu are very satisfied with this success rate. It will feel strange.

The thousands of detectors Lei Tiantang put on a large scale and their psychological expectations are 80%. As long as 80% of the detectors can successfully complete their tasks, they will be satisfied. Even if the environment inside the solar system is still safe, but That doesn't mean it's not dangerous at all.

Various tiny space debris, the gravitational force of the sun and other planets, the failure of the probe itself, and other factors will cause the loss of the probe. It is really good to have 9 of them enter the orbit of Mercury.

There are 10 satellites in total to provide Lei Tiantang and the others with detailed data. They won't need to use it here to detect Mercury's data in the future. After all, Mercury is so small in size that it is even more famous than Ganymede and Titan. The Titans are even smaller.

What if it's more massive than both of them? The speed and efficiency of detector detection depends on its volume,

It's not its quality, so the data provided by these 10 satellites is enough for Lei Tiantang to set the construction location of the base before he came here.

After all, they only plan to build an outpost on Mercury, and they don't have to worry about the location selection. On Mercury, as long as they don't want to die, they have to choose those relatively risky places. There is no problem in other places. Anyway, They are only building underground bases.

The underground environment of Mercury is much better than that of Mars and Venus. Don't look at people's small size, but they are solid! Why is Mercury so massive? That's because people are made up of about 70% metal and 30% silicate material!

Mercury's density is 5.427 g/cm², the second highest in the solar system, after Earth's 5.515 g/cm². If the effect of gravitational compression on the density of matter is not taken into account, the density of Mercury's matter would be the highest - 5.3 g/cm?? of uncompressed Mercury matter, compared to 4.4 g/cm?? of Earth's matter. ?

Details of Mercury's internal structure can be inferred from its density. Earth's high density, especially its core, is caused by gravitational compression, and Mercury is so small that its interior isn't squeezed too hard.

So to have such a high density, its core must be very large. The mass of its inner core can even account for 2/3 of its total mass, while in comparison, the mass of the inner core of the earth only accounts for 1/3 of the total mass of the earth.

The main components of this bulge are iron, nickel and silicate. According to this structure, according to the data detected by the detector, the iron content of the entire Mercury may reach 2 trillion tons. If the current production of steel on the entire earth is based on Calculated by annual production (about 800 million tons), it can be mined for 240 billion years.

Of course, Lei Tiantang and Kuafu don't look down on these metal resources. The various materials left by the body of the small black hole swallowing the star system are more than 10 times more than this, and they can be used at any time. In this case, of course, they will not mine the metal resources here on a large scale.

However, after the construction of the underground base is completed, if Kuafu is bored, he can mine some by himself. Otherwise, the energy of a nuclear fusion reactor is only used to maintain the normal operation of a base, which would be a bit of a waste.

And even without considering its metal core, if the crust layer that can be preserved so close to the sun is not strong enough, it must have been evaporated by the sun long ago.

This is also the reason why Lei Tiantang and the others landed directly at the selected location as soon as they entered the orbit of Mercury. Although the temperature rise on the surface of the spacecraft will not cause any damage to the spacecraft, it is so far away from the sun. Nearby, Lei Tiantang still didn't want to stay too long.

Because after seeing it, he can easily calculate in his mind how much his ability will increase if he devours it. What a terrible thing!

You must know that he is a native of the earth. He only appeared by this star. Human beings on the whole earth cannot do without this star of life, so even if he can't help but flash these data in his heart , and he was not so mad that he brought himself one of the few ability enhancements by destroying the sun.

In order to get rid of the influence of these distracting thoughts, Lei Tiantang decided to finish work early and finish work early, so after successfully leaving his footprints on Mercury and keeping the evidence of his successful punch-in, he started work directly with a positive attitude towards work. no!

Since there is no need to build such a troublesome thing as a collider at this base on Mercury, the construction of the entire underground base is not too simple for Lei Tiantang and Kuafu, who are already proficient in business. When the time comes, the construction is completed successfully.

Even the passages and processing spaces for mining and smelting ore were prepared for Kuafu Xian's boredom, so he could just take this opportunity to test the self-sustaining ability of the underground base in a long-term unsupplied state.
