If viewed through the scientific lens of the Earth Era, the Divine Matrix Civilization's broadcast would certainly violate the theory that information could not travel faster than light, because the Divine Matrix Civilization's Gravity Broadcast clearly propagated faster than light—much faster.
Their broadcast messages appeared throughout the Milky Way Galaxy.
Of course, it was not as though they could shout from one place and be heard across the entire Milky Way Galaxy. Though the Divine Matrix Civilization was powerful, it could not achieve that.
They had arranged in advance for Probe Spaceship Squads to travel to every spiral arm of the Milky Way Galaxy, setting up numerous information anchor points in each one, then broadcasting across the galaxy through those anchors.
Gravitational Waves spread in all directions from the starfields containing those anchor points as though raindrops had appeared from nowhere, even penetrating one hidden Small Universe after another.
After reaching the level of a Level Six Civilization, due to the existence of Characteristic Technology, many civilizations possessed communication methods unlike those of ordinary civilizations. The Silver Heart Alliance did, and so did the Divine Matrix Civilization.
Quantum Entanglement communication had failed, but these civilizations could still rely on their own wisdom to find extraordinary technological paths.
Of course, no matter how powerful a civilization like the Divine Matrix Civilization was, it was ultimately only a Level Six Civilization. They might be able to make use of the laws of physics, but they certainly could not alter them.
Gravitational Waves were ripples in spacetime. The Divine Matrix Civilization naturally could not make them travel faster than light within the three-dimensional Great Universe. Thus, this so-called faster-than-light information transmission actually made use of Gravity's ability to penetrate dimensions. Through their profound research into Gravity, they had created this wide-area information transmission
