I recently watched the Anthony Cumia show who hosted Neil deGrasse Tyson and it's highly entertaining but touches some great current space topics. Apparently they just pulled him off the street !
It's an excellent rebuttal discussion on the Flat Earth theorists and Neil shares his thoughts on why in general theories like this start in a misguided way. I particularly enjoyed the debate on the race for space exploration and some dangers of private enterprise.
I believe as we journey into the new age of space exploration private enterprise is going to similar in a way as the Spaniards. As we venture in Mars exploration the idea of political means are actually going to be heavily outweighed by economic benefits.
