"What is the universal currency of Cosmic Civilizations of Seventh Level and above?"
"One thing we can confirm, which is different from our previous conjecture, is that it definitely isn't energy, at least not merely energy."
"According to our current technological level and progress, when we reach the Fifth Level Cosmic Civilization, we can manufacture Black hole reactors, which are actually an indirect source of infinite energy; as long as there is matter, we can obtain sufficient energy. However, this is far from the end."
"At the Sixth Level Cosmic Civilization, we hypothesize that we should be able to achieve true Singularity reactors, and then move on to vacuum zero-point energy extraction. This is already the pinnacle of energy sources that our scientific domain can achieve through laws, mathematical formulas, and scientific theories. Going further up would enter the realm of the Information Universe."
