Why are the Trisolarans not afraid of humans building space elevators?

What the Trisolarans are afraid of is the nanomaterials Wang Sen is researching.

In "The Three-Body Problem", the nanomaterials studied by Wang Miao are the key materials for making space elevator cables. Assuming there is a space elevator, humans can dismantle the power module and lunar module of the Apollo project into parts and send them into space, and then assemble them in space.

This is not only as simple as saving 2,200 tons of fuel, but also making the Apollo lunar landing spacecraft larger, carrying more fuel, flying farther, and conducting longer explorations.

It can be said that under the current conditions, before there is a qualitative leap in basic human science, the space elevator is not only a necessary condition for humans to leave the earth on a large scale and conduct deep space exploration, but also a necessary condition for the industrialization and development of human spaceflight. The basis for scaling.

In "The Three-Body Problem", this is the reason why the Trisolaran people attach so much importance to Wang Miao and even use sophons to "make the whole universe shine for him". The Trisolarans, who are significantly ahead in basic science, are not actually afraid of humans using space elevators to build interstellar battleships to fight against them, but they are afraid of humans escaping on a large scale through space elevators.

The biological history of the Trisolarans

The civilization of the Trisolarans has experienced nearly two hundred times of destruction and rebirth. After a long period of selective evolution, the Trisolarans have given up their cowardice. , became calm and rational, and the social form was also a highly centralized authoritarian society.

It should be noted that the Trisolarans who appear in the book only refer to the latest generation of Trisolaran civilization, which is completely different from the more than two hundred previous Trisolaran civilizations. The Trisolaran civilization was not created by the same species.
