If anti-gravity technology were exposed, public opinion wouldn't be as it is now; the world would be in an uproar because everyone would be clear that a qualitative breakthrough in science and technology was about to happen, and people's lives would undergo significant changes as a result.
Furthermore, there would be a major shock internationally, and the impact of anti-gravity technology might even surpass that of nuclear technology.
Zhao Yi was indeed concerned with anti-gravity, but what he cared about was not the technology itself but the principle. Theoretical research was the true foundation of everything.
After the emergence of photonic anti-gravity, theoretical research on space and particles would undoubtedly achieve explosive breakthroughs.
The upper echelons were well aware of this.
