Black Knight satellite conspiracy claims that there is a spacecraft orbiting Earth that is of alien origin, and there is an ongoing world wide cover-up regarding its existence and origin. If it is real, then all of those people would have to have tried to hide it to an extent. It is most likely a bunch of stories and space junk lumped together into a conspiracy theory, but you never know. It is fun to think about. What do you think the Black Knight satellite is? #ufo #aliens #conspiracy #space #
