So is gravity.

Yet they seem reluctant to test that one by stepping off the roof…

One of the top Moon landing denialists, the late Ralph René , was also a pi denialist. He claimed that pi does not in fact go on to an infinite number of decimal places and, naturally, mathematicians are conspiring to cover this up. Other than a general luxuriation in evil, he did not explain why they would do this.
He was probably not, however, a pie denialist since he weighed about 400 pounds.
Needless to say, he was a 9-11 truther in his final years. He shuffled off this flat Earth in 2008.
