A drop of water wiped out the human fleet. What is the difference in civilization?

In the science fiction novel Three-body, human civilization is far from three-body civilization. In the doomsday war, the three-man team wiped out the human fleet, just as the modern army wiped out the feudal army.

The Soviet astronomer Nikolai Kardashev divided advanced civilizations into three grades according to the way they used resources, namely:

First-class civilization: it can use all the resources of the planet and correspond to the earth.

Secondary civilization: it can use all the resources of its star system, corresponding to the solar system.

Third-level civilization: it can make use of all the resources of this galaxy and correspond to the Milky Way.

At present, the level of human science and technology can not make full use of the earth's resources, and the level of civilization is about 0.7. In the novel Three-body, human beings have basically reached the first-class civilization during the doomsday war. At that time, the three-body civilization could realize large-scale interstellar travel and belonged to quasi-II civilization.

That is to say, in the doomsday war, human civilization and three-body civilization are completely different by one level, but the gap of this level is simply a world of difference. Three-body people only used a drop of water and destroyed more than 2000 human starships in a few minutes. Humans didn't even have a chance to resist.

In the three-body system, the surface substances of water droplets are connected by strong interaction. The strength of strong interaction is 10 38 times of gravity and 100 times of electromagnetic force. Ordinary matter can't destroy this structure at all. According to the description of quantum mechanics, the destruction intensity from the nuclear level needs to be nearly 1000 trillion degrees, so water droplets can easily destroy human warships without any damage.

In human history, there have been similar wars between different levels of civilization. 1860, the famous Baliqiao Battle took place between the British and French allied forces and the Qing army. The Qing army dispatched 30,000 soldiers, and the British and French allied forces involved more than 8,000 people. This war of aggression eventually led to the destruction of Yuanmingyuan.

In this campaign, the Qing army was basically cavalry, equipped with spears and bows and arrows. Only a few cannons remained at the level of more than 200 years ago, and could not hit the enemy's position at all, while the British and French Coalition forces were equipped with advanced firearms and cannons at that time. After the battle began, the Qing army could only approach the enemy by suicide attack and then fall under the enemy's gun. In the end, the Qing army suffered more than half of the casualties, and the British and French Coalition forces only died 12 people. This is a typical feudal army against the modern army, which is also the gap of civilization level.
