For the first question, there is a problem when it is raised.
When Cheng Xin and Guan Yifan fell into the black space, they did not rely on the small universe to leave. At this time, they did not know that there was a small universe. They started the "neuron" control system of the shuttle and then started the "antimatter" engine to let the shuttle escape from the speed of light and the black area.
So soap tree children's shoes, this section of the story you need to review, write a 500 impressions, Ben Gu to check.
As for what the light speed spaceship does later, there is no need to answer it! As for the fact that they can reach any place in the universe in an instant, it is impossible, even if they are in the small universe of brain flower, they can not reach any place in an instant.
This problem is more interesting, pigeon can not talk about cracking the security statement, just a simple view!
The so-called space safety statement is the black field, which is generated by thousands of spacecrafts driven by the curvature of the sun, radiating to the outer space of the solar system, leaving the wake connected, forming a low light speed black hole covering the whole solar system, directly reducing the speed of light to 16.7 km / s.
Under the influence of the black field, light can be slowed down, not to mention other things. Therefore, people in the black field do not have any threat, because their technology has been limited to death, and the computer's operation efficiency is extremely low (refer to Guan Yifan to start "neuron" computer, it is known that general equipment fails in the black field, and the neuron system is extremely running Not to mention artificial intelligence, such a civilization is unlikely to pose a threat to other civilizations.
In addition to the black space, there are thousands of spacecrafts with curvature that left in order to create the black space.
These spaceships are the kindling of civilization. They will definitely not stay and hover around the mother planet, because their journey is the sea of stars, but this does not mean that they will not pay attention to their own situation. Therefore, the security statements issued by the black domain are actually threatening.
The civilization in the black area cannot pose a threat to the outside world due to the problem of scientific and technological level; while the civilization outside the black area is like a hidden hunter. When someone attacks his own home, he will attack.
No one is willing to provoke such civilization. Do you remember the core "dark forest" principle set by the three bodies? Hide yourself and clean up. In this case, there is a sequence. Only by hiding well can they say that they can clean up others. When they clean up the civilization in the dark region, they will inevitably expose themselves. (don't doubt that, as long as you have done something, there will always be traces. In addition, no one will know whether those who leave the parent planet will have another technological explosion.)
Therefore, when there are too many variables in the process of cleaning up, or the cost is very high, or they may expose themselves, the first thing the cleaner should do is to hide himself. After all, he does not know whether he has been exposed or under the attack of others.
