I've been entertaining the idea that there may be some sort of covert warfare going on between the USA and China, and that the floods in China, and the covid narrative, may be components of that warfare. So here's today's high octane speculation. What if there was a suspicious “signal like” transmission, that only the very largest radio telescopes, such as the one in southwestern China, or Puerto Rico's Arecibo, was able to pick up? And what if one, or the other party in this covert warfare wanted to prevent its opposite number from hearing it? What would one do?
