I have a little black hole

If you look at the sun on Earth, it's like a hot little disc in the middle of the day, then it's like a large version of duck egg yolk in the morning and evening, so what would the sun look like on the nearest Mercury to the sun?

From Thunder Tang's now pretending emotions can be heard. Because Mercury's distance from the Sun is the closest in the entire solar system, the Sun will naturally be much larger on Mercury than on Earth. He is right to say bullshit.

In fact, on other planets, the size of the sun is inversely proportional to the distance of the planet from the Sun, of course. The Earth is 1 astronomical unit from the Sun, while Mercury is 0.387 astronomical units from the Sun.

So if you look at the Sun on Mercury, it's 10.378 = 2.645 times the size of the Earth. If you calculate the circumference of this number, you get 8.31 times the number. So if you look at the Sun on Mercury, it should be more than 8 times the size of the Sun on Earth.

But because there is no atmosphere on Mercury, there is no sunlight. So even though the sun is huge and the sun is intense on Mercury, because there is no atmosphere, it does not scatter and refract sunlight. The sky on Mercury still looks black, like the color of the Earth's night sky, and stars can be seen behind the sun.

So the pretending speech behind Lui Tiantang is still bullshit. If you can still see the stars in front of such a big sun, it's a ghost!

Though the company has placed two probes in Mercury orbit, Lui Tiantang put a large number of probes in the solar system on their last cruise to Mars, and of course Mercury has one here.

A total of 12 probes flying to Mercury ended up in Mercury orbit. Whether it's Thunder Tang or Kwak Father, they'd be surprised if they were 100 percent in Mercury orbit.

Thousands of large-scale detectors are deployed. Lei Tiantang's psychological expectations are 80%. If only 80% of the detectors can successfully complete the task, they will be satisfied. Even if the environment inside the solar system is safe, but this does not mean that it is not dangerous at all.

All kinds of tiny space debris, gravitational pull of the Sun and other planets, failure of the probe itself, etc., can cause loss of the probe, and it is really good to have nine in orbit of Mercury.

There are 10 satellites in total to provide Lei Tiantang with detailed data, so they don't have to come here to probe Mercury's data again, after all, Mercury's measurements are so minimal that they're even smaller than the famous Titans of Io and Titan.

What if it's bigger than all of them? The speed and efficiency of the detector's detection is based on its volume, not its quality, so the 10 satellites provide enough data to locate the base before Thunder Tang came here.

After all, they only intend to build an outpost on Mercury, and they don't have to worry about site selection, and on Mercury, they either have to choose to die in places that are relatively risky, or they have no problem anywhere else. They only build underground bases anyway.

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

Mercury has a density of 5.427 g cm ³, the second highest in the solar system, after Earth's 5.515 g cm ³. Mercury will have the highest density if the effects of gravitational compression are not taken into account - 5.3 g cm ³ for uncompressed Mercury, compared to 4.4 g cm ³ for earth below.

Details of Mercury's internal structure can be inferred from its density. The high density of the Earth, especially the core, is caused by gravitational compression, while Mercury is so small that its interior is not strongly squeezed.

So for it to have such a high density, its core is bound to be huge. Its kernel mass can even account for 23 of its total mass, in contrast to the Earth's kernel region, which accounts for only 13 of its total mass.

The main components of this nucleus are iron, nickel, and silicate. Based on this structure, based on the data detected by the detector, it is estimated that the iron content of the entire Mercury could reach 2 trillion tons, which, if measured by the annual production of steel now produced on the entire planet (about 800 million tons), could be extracted for 240 billion years.

Of course, Lui Tianben and Hua Fan do not see these metallic resources. The small black hole body eats more than 10 times more of the various materials left by the star system, and they can still be used at any time. In this case, of course, they will not exploit the metallic resources here on a large scale.

However, after the construction of the underground base is completed, Kwapa can completely mine some by himself if he is bored. Otherwise, it would be a waste to use so much energy as the nuclear fusion reactor to maintain the normal operation of a base.

And even without considering its metal core, the crustal layer that can remain so close to the sun would certainly have been evaporated by the sun if it wasn't strong enough.

That's why Thunder Tang landed directly in Mercury orbit towards the selected position. Although the temperature rise on the surface of the ship would not cause any damage to the ship, Thunder Tang is still unwilling to stay so close to the sun.

Because seeing it makes it easy for him to calculate in his mind how much more power he would gain if he swallowed it!

You know, he was born and raised on Earth, and he emerged from this star. Humans on the whole planet cannot live without this star of life, so even if he can't help but flash these data in his own heart, he is not mad enough to bring himself a few ability enhancements by destroying the sun.

In order to get rid of the influence of these misconceptions, Lui Tiantang decided to finish the work early, so he successfully left his footprint on Mercury and retained the evidence of his success, and then he started the work directly. The working attitude was positive!

Since this base on Mercury doesn't have to build colliders anymore, the construction of the entire underground base is not too simple for Lui Tiantang and Kwapa, who are already skilled in the business, and it takes less than a day to successfully complete the construction.

Even the passageways and processing space for mining and smelting ore are ready when Kwaphan is bored, and this is an opportunity to experiment with the long-term non-rechargeable self-sustainment capabilities of the underground base.
