Just as everyone remained silent in contemplation, one scientist experienced a sudden flash of inspiration. As if he had just unraveled a cosmic mystery, he hurriedly exclaimed:
"The Viridian Empire drone! That drone's technology completely surpassed our own, but it still didn't have a miniaturized, controllable nuclear fusion reactor inside! It was powered by an advanced fission engine!"
"They are a true Interstellar Civilization, yet they couldn't engineer a stable fusion reactor to fit inside a small spacecraft with a two-meter diameter."
"Two meters across... that's not exactly tiny, but it apparently wasn't large enough to house a functional fusion device."
"This might explain... the sheer impossibility of creating a small-scale, controllable nuclear fusion reactor!"
"The smaller the reactor, the harder it is to stabilize!"
