I have a little black hole

Humanity is proud. In the 4.6 billion years since the birth of the planet, countless lives have emerged. Only humans eventually evolved into intelligent life and developed into the current scientific and technological civilization.

When you look up at the sky, you realize that the Earth is so small. A lot of people think that the universe is so big at this point in time. Is the Earth the only civilization, and how many civilizations in the universe are like Earth?

Seeing the vast universe, the confidence and pride that once existed were shattered. Looking at the Earth from a cosmic perspective, the Earth is too small. And human technology can't even run out of a tiny solar system. Do we still feel powerful?

As far as the hierarchy of civilizations of humankind is concerned, as early as the last century the Soviet scientist Nicolas Kardashev proposed the famous “Kardashov Index” criteria for the classification of cosmic civilizations, according to which the hierarchy of civilizations can be classified using energy technology.

First level civilization, which is the owner of planetary energy, means that they can dominate the sum of all the energy on their planet.

According to this criterion, humanity's current hierarchy of civilizations can only be roughly divided into levels of 0.8. Because human beings can use most of the Earth's energy, but there are places where human beings are still unable to use it.

Even infinite gravity groups have now begun to use more energy-grade nuclear fusion reactors to deliver energy on a large scale, but that does not mean that humans are truly able to take full advantage of all of the Earth's energy.

Secondary civilizations can make use of all the energy of this galaxy, such as that mentioned in the famous Dyson sphere theory, which makes full use of the energy of the central star, and secondary civilizations can make use of that energy.

The large-scale use of solar energy before humankind was only the first use of star energy, and in recent years the Infinite Gravity Group's 'Space Energy Plant’ programme has begun to address this civilized hierarchy.

Even now, 120,000 kilometres away from the Earth, the Infinite Gravity Group has successfully built two super-solar power stations with a total area of 300,000 square metres, and has been able to deliver a large amount of energy to the Moon, guaranteeing that the two large bases on the Moon will be able to function normally during the half-month period of the Moon Night and even deliver a certain amount of energy to the Earth.

But such utilization efficiency is not particularly high. It is 18,000 miles away from being able to fully use the energy of the whole Sun. There are not many problems that need to be solved in this.

Kwak Father said that there are factors in this accumulation. There is not enough time to accumulate technology. It is simply impossible to achieve the breakthrough of civilization level, even if Lui Tiantang hangs.

And a tertiary civilization can use the energy of a galaxy. The symbol is that this level of civilization can already fly at light speed, or travel at super light speed. This is also the most wanted technology in front of Lui Tiantang, but you can see how difficult such technology is from them to now.

As for the four-tier civilization, it can be called a divine civilization. Four levels of civilization can already basically use the energy of the entire universe.

Of course, this is a rougher division. If you refine it a little bit, these four levels can be refined into 12 levels. Even so, the current level of human technology in this level still does not exceed 1 level.

0. Our Earth civilization (zero-order civilization): equivalent to 0.8 first-level civilizations, there are initial stages of space station technology, space technology, various physics theories, and mankind has been able to initially look into space.

1. First level civilization: migration can only take place between planetary systems. And other planets, such as the Moon and Mars, are not capable of colonizing between galaxies.

Even with the participation of the Infinite Gravity Group, mankind's development of the Moon and Mars is still in its infancy, and large-scale retrofitting and immigration are still far from complete.

So there is nothing wrong with Kwapa giving Lei Tiantang cold water, because according to this standard, it is obviously impossible to say that humans have reached the first level of civilization. Humans are still that poor zero-level civilization, but now they are eligible to break through to the first level of civilization, as for the second level of civilization, there is no need to think about anything.

2. Second-level civilization: It is possible to migrate between adjacent galaxies, and the range of activities is within the range of 10 light years. By this standard, even the unmanned spacecraft that Lei Tiantang sent Kwapa to launch is not out of the solar system!

There are no detectors to reach, let alone immigration or anything like that. Even if Lei Tiantang and his team have completed the design and construction of the spacecraft "Earth", there is no guarantee that they will not be able to quickly explore the galaxies around the solar system. Not to mention the fact that humans can reach the second level of civilization.

3. Class III civilization: able to carry out basic navigation in Hanoi. Basic navigation is possible where galactic species can only be found. However, there are communication restrictions due to excessive voyage time. The range of activities is about 100 light years.

It's not that you can't go further, but you don't have to go too far. Even if you find something good, it's a loss to bring it back.

4. Grade 4 civilization: can initially apply natural wormholes for Hanoi navigation. This problem is also the most troublesome problem for Lei Tiantang at present. You know, the solar system is about 22,000 light years away from the small black hole!

Although it's all in the galaxy, even if the ship can fly at light speed or even superlight speed, it's impossible to get there in a lifetime from this side of the solar system. Even if the ship is flying at 10 times the speed of light, it will take about 2200 years to get there!

So the only thing they can do is figure out how to find a natural wormhole or a weak spot in space, see if they can jump straight to their destination quickly, or else he'll just have to wait on the side of the solar system.

If he is separated from the Earth for more than 2,000 years, then even if he can live that long, he succeeded in devouring the small black hole and returning to the Earth immediately, then the existence of the Earth will still be a problem.

Even if the earth is lucky to still exist, then the change of the mulberry fields in such a long time is enough to make everything that Lei Tiantang is familiar with disappear into the long river of history, then what's the point of him busily eating up the small black hole body?
