"However no one seems to talk about about the space junk already out there. NORAD and SPACECOM tracks millions of pieces that if they pierced the ISS would kill the astronauts in a matter of milliseconds." not only that, but it's well known that asteroid trackers have and will fail to spot asteroids large and fast enough to destroy half of humanity. black knight has been around for far too long to be a NASA super weapon, but it's suspicious nevertheless. it's probably some random asteroid with an old satellite transceiver stuck on it.
