None. And I encourage you to examine my photos. However, the phenomenon these photos depict can be independently verified. All you, I, or anyone else need do is observe some sunsets a few nights in a row. However, I dont think either of us is getting blasted into space by a corrupt government organization to verify the shape of the earth anytime soon.

I still don't see what the government has to gain from us believing something false. Can you explain what they would gain from everyone believing the earth is round if it is indeed flat?

$18 billion a year, for starters. The conspiracy would only need to be perpetuated and sustained by a few select individuals. A few hundred at the most. Your average Joe who works at nasa probably believes the lies as much as anyone else. Also, these elite few would be very invested in perpetuating society wide belief in the Religion of Science. Religion is a powerful tool in directing the energies (and ultimately the production) of the social masses. If they think along certain generalized patterns that [b]you[/b] create, what they produce and how they spend their money in turn reinforces the social structures that you want to reinforce. At its very core society is based on structures that perpetuate control. Control in turn perpetuates social structures. Today, as it has always been in advanced societies, control can only be achieved efficiently and bloodlessly if everyone thinks along similar lines of thought. As I said, Religion plays a major role. As belief in god has declined, society has gradually substituted science as the new religion. Sure, its different. But at the end of the day people go home from a long days work feeling just as liberated (and just as exhausted). The social elite profits. Telling everyone that the religion of science is predicated upon a massive lie, would fundamentally weaken the faith of the masses in their accustomed social structures. As you an see the answer to your question is very complicated and very obvious at the same time.
