Of course, that was only a visual effect.
The warships and vessels could still contact one another through their communication devices, but not through Tachyon Communication. They had to use Quantum Entanglement Communication instead.
Yes, after entering the Star Gate, the civilizations discovered that the once-convenient Tachyon Communication had actually failed. The tachyon generators still functioned normally, but every burst of tachyons transmitted vanished without any feedback, like mud oxen sinking into the sea.
The tachyons once used for communication seemed to have been sent somewhere unknown by this strange spacetime tunnel after transmission. Or perhaps they had become short-range communications and been reabsorbed by spacetime itself back into the Fast World.
Even the Silver Heart Civilization's scientists, who excelled most in communication technology, found it difficult to determine the cause of this strange phenomenon.
Humanity, however, was reminded of something the Precursors had encountered long ago: Hyperdistance Communication through Quantum Entanglement had not failed back then. Of course, that referred to Hyperdistance Communication. Quantum Entanglement Communication limited to light speed still worked.
After discovering that Tachyon Communication was useless inside the Star Gate, everyone began communicating through Quantum Entanglement Communication. It worked, but it was limited to light speed. Since the Great Voyage fleet was enormous, communication efficiency became extremely low.
Yet it was precisely because Quantum Entanglement Communication still worked and remained limited to light speed that many civilizations' scientists felt as if time itself had become confused. They found that contacting ships ahead that had entered the Star Gate earlier sometimes took longer than contacting warships farther away.
The closer distance should obviously have meant less time, yet such a counterintuitive phenomenon appeared. It was truly baffling.
Furthermore, there seemed to be a problem with scientifically defined time itself.
The scientists discovered that aboard ships traveling within
