151) If Earth were a spinning ball revolving around the Sun it would actually be impossible for star-trail photos to show perfect circles even at the North Pole! Since the Earth is also allegedly moving 67,000mph around the Sun, the Sun moving 500,000mph around the Milky Way, and the entire galaxy going 670,000,000mph, these four contradictory motions would make star-trail time-lapses all show irregular curved lines.
The most commonly accepted explanation of this is that the space agencies of the world are involved in a conspiracy faking space travel and exploration. This likely began during the Cold War's 'Space Race', in which the USSR and USA were obsessed with beating each other into space to the point that each faked their accomplishments in an attempt to keep pace with the other's supposed achievements. Since the end of the Cold War, however, the conspiracy is most likely motivated by greed rather than political gains, and using only some of their funding to continue to fake space travel saves a lot of money to embezzle for themselves.
