It's racism to doubt that China has antigravity ships and that this is the obvious commonsense answer to these sightings? Prior to the US having a nuclear program there were papers being published on the possibility of fusion reactions that split the atom. These papers then disappeared during the Manhattan project, signaling that research was happening which was being suppressed. Is there evidence that China had papers on antigravity research and that such papers have recently stopped being published.
