[Author's Note – Understanding the Quantum Foam Drive (QFD):
Let me take a moment to explain something that might confuse some readers: why does FTL travel in the story seem to get faster over time?
In the beginning of the novel, the ship took nearly 12 hours to cover just 7 light-years, but now it can travel 22–25 light-years in only 2.4 hours. This isn't a mistake—it's because of the different FTL modules used.
Earlier, the ship was using a basic form of FTL. But now, it's equipped with something far more advanced: the Quantum Foam Drive, or QFD for short.
So, how does the QFD work?
The idea is inspired by a real scientific theory from the 1950s by physicist John Wheeler. He proposed the existence of quantum foam—a chaotic, turbulent layer beneath normal space where spacetime is extremely unstable and full of micro-wormholes.
