According to the lunatic fringe we are supposed to be hit by ‘Planet X’ this day — September 23, 2017. Did they realize that it was the anniversary of Neptune, the ‘Planet X‘ of its time, being discovered.
Neptune’s discovery, as I outlined it above, was pretty amazing and a testament to the cleverness of humans. Its existence was determined mathematically! That was 171-years ago. It still has me in awe.
