Tesla was speaking about the nature of the scientific community (your community, not the youtube community), he probably wasn't aware of the "globe earth deception", but calls the model into question with his moon statement.
The flat earth only is disproven by your false model and false equations, the model of our reality doesn't disprove the theory. The only thing disproven for sure are your false video and images of "outer space", and I guess the globe model too but not as definitively as the CGI.
I don't want to go back and forth, tesla wasn't perfect, but he wasn't completely indoctrinated and deceived either, therefore a threat to the agendas of the "scientific community".
