Looking at this information, Su Yu fell into deep thought.
This was more or less what he had imagined. The Singer Civilization ruled the entire Supercluster and possessed incomparably immense power.
However, the Supercluster was simply too vast, spanning a full 520 million light-years. The Singer Civilization could not possibly exercise direct control over all of it and could at most control only some of its star systems.
The only surprise was that the Singer Civilization had actually built supercities spanning several stars! This was completely beyond his understanding.
Even the shortest distance between stars was four or five light-years.
If Blue Star were compressed into a glass sphere one centimeter in diameter, the distance between two stars would be equivalent to eighteen times the straight-line distance from Beijing to Guangzhou!
Therefore, civilizations like theirs, which could only build on planets, simply could not imagine how enormous the Singer Civilization's cities were. The difference was like that between an ant and Earth!
Thinking of this, Su Yu could not help asking Sheng Ge, "Lord Holy Song, can the Singer Civilization really build cities spanning several light-years, or even dozens of light-years? Aren't they afraid that excessive mass will cause gravitational collapse?"
"I didn't believe it at first either," Sheng Ge replied. "But all kinds of evidence show that the Singer Civilization truly has such cities, and more than one at that.
"These cities are home to quintillions of intelligent lifeforms, as well as a large number of intelligent machines. According to the descriptions, intelligent lifeforms govern the entire cities.
"As for the issue of excessive mass causing gravitational collapse, I think the Singer Civilization must have a way to solve it. Perhaps those cities are not single unified entities, but are pieced together in discontinuous sections."
"Ah." Su Yu sighed
