Yesterday there was a really exiting radio show on the internet with some germans which research the flat earth topic
Dr. rer. nat. Matthias Kleespies told the show listeners of a new theory because he found out that sometimes people see "2 suns"
maybe thats the reason why they are spraying chemtrails to hide this secret or connecting it to nibiru
