After introducing the concept of Vacuum Decay, the Divine Matrix Civilization also told Humanity and the Daya Civilization about their speculation regarding the disappearance of Level Seven Civilizations, as well as their theories about why so many civilizations were trapped at the Level Six Civilization stage.
The Divine Matrix Civilization believed that the disappearance of Level Seven Civilizations was related to Vacuum Decay. In ancient times, large numbers of Level Seven Civilizations had used Vacuum Zero-Point Energy without restraint, causing Vacuum Decay to emerge in the universe. This decay might already have occurred somewhere, or in multiple places, and was spreading throughout the entire universe.
Scientists of the Divine Matrix Civilization said that space after decay would become True Vacuum. The immense energy of Vacuum Zero-Point Energy would become an energy-absorbing reaction there, and the entire universe would fall to a lower energy level. All energy sources in the present universe that civilizations could use would cease to exist.
Sentient Life based on the existing laws of physics would perish as a result.
The disappearance of those Level Seven Civilizations, and even civilizations above Level Seven, was because they had been seeking a solution to these problems. Perhaps they were somewhere in a corner of the universe, trying to extend its lifespan. Of course, they might also have been trying to transform themselves into lifeforms capable of adapting to the laws of the universe after decay.
During that process, many conflicts might have occurred, and war would have been unavoidable.
It was easy to imagine that wars between civilizations of that level would inevitably be world-destroying. The Divine Matrix Civilization's scientific community speculated that the failure of Quantum Entanglement-based Hyperdistance Communication in the Milky Way Galaxy was very likely a product of the wars of that era.
