The conclusions reached by philosophical experts studying Cosmic Sociology were not baseless fantasies, but deductions based on humanity's existing theoretical advances. In other words, humanity's theoretical progress was correct, and their inferences were most likely correct as well.
Such conclusions were undoubtedly extremely important. Although they could not directly drive technological development, they pointed out many viable paths for humanity's future. They also let humanity know where it should go, where it should not go, what information it could answer, and what it must not do. This was a deeper understanding of the universe and cosmic society, much like humanity's initial realization of the universe's brutality. It was knowledge that an interstellar civilization had to grasp in order to establish itself in the universe.
This conclusion first showed humanity the strength of a Level 5 Civilization. They might have mastered the technology to traverse Wormholes, perhaps even create some Wormholes. Then there were the Starry Sky Gas Stations. For a Level 5 Civilization, the fuel they refueled with was Negative Energy. With this understanding, once humanity reached the level of a Level 5 Civilization, it could avoid many detours and direct its research toward this field.
That was, technology for extracting Negative Energy from a black hole's Negative Energy Field.
And since it was a gas station, the Negative Energy extracted from a black hole's Negative Energy Field would certainly be easier to obtain than Negative Energy manufactured by a Level 5 Civilization itself. Based on humanity's current understanding, the possible method for creating Negative Energy was the "Laser Energy State" method. This was surely incomparable to a celestial body.
Creating it would certainly consume energy, just as producing Antimatter required more energy than the Antimatter itself contained. It was unknown whether the peculiar energy known as Negative Energy followed
