If the long string of attempts at debunking it never managed to scalfirvi - something, by the way, not too surprising -, here's another topic that perhaps could convince you once and for all.

To put it in black and white, on Plos One page was David Grimes, a physicist at Oxford University: it is a mathematical model that can predict the likelihood of conspiracy theories based on the number of people who should be hypothetically involved .
The reasoning behind the search for Grimes is flawless: the greater the number of people involved in a conspiracy, the harder it is to keep it secret.
"Several conspiracy theories about science," said researcher at the Telegraph microphones.
Other, including misinformation about vaccines, can cause serious damage.
In any case, however, do not always believe in conspiracies is wrong: think, for example, the theories on the activities of the US National Security Agency, confirmed by Snowden revelations ".
Grimes essentially used data relating to conspiracy theories of the past to build a mathematical model able to determine how long a date may remain secret information on the number of people who know the information itself.
Or, in other words, to estimate the probability that a conspiracy is revealed to be a mole or found in other ways.
The Grimes model was used to analyze some of the most popular conspiracy theories: because a conspiracy kept secret for five years, says the researcher, the conspirators must be less than 2521.
According to his calculations, moreover, failure to landing on the moon was discovered in 3 years and 8 months, fraud on climate change in 3 years and 9 months, the conspiracy vaccine in 3 years and 2 months and the existence of a secret cure for cancer in 3 years and 3 months.
