What if you have it wrong and there is no conspiracy? A genuine question, please don't delete.
Only some indisputable authority is able to make claims about absolute wrong vs right concerning the shape of earth and more.
I do not know such authority among earthlings.
I cannot convince others, because i possess the same human handicaps without absolute authority.
And it seems that greed, power and money is infiltrating ''scientific research'' more than ever before, so that we are further and further away from objective universally accepted ''scientific truths'' that does not seek to please anyone and has no other goal than to research, conduct, measure, conclude and repeat.
If one reads about the supposed ''lost / destroyed technologies'' (from the highly technological advanced late sixties and early seventies concerning space exploration) that prevents NASA to go back to the moon on a short notice, i believe that i am dealing with scumbags of the highest degree that can claim whatever they want about earth in their hypothetical universe, but unless they show some signs of dignity, honesty and open minded debate i would trust a junkie to look after my wallet far more than NASA & Co. (A bottomless pit of taxpayer's money)
And without NASA most of the claims about earth, the moon and the universe would have to begin from almost scratch.
''but.....the Sovjets someone asks '' ?....the Sovjets were also lying scumbags about everything in their totalitarian system with ongoing murder, slaughter and exciling any protest or different opinion whatsoever.
Yeah those c...suckers told the truth about space, just as the good ole USA who murdered more inhabitants of foreign countries post WW2 than the regime of Hitler did during the second worldwar.
Couldn't it be somewhat plausible that such evil regimes lie about earth, it's shape and about their space achievements ?
Bottom line, i am willing to humble myself in front of everyone who is interrested when a real authority shows me my errors and invalid believes.
Not those old ones still in power (dependent on the same financial system that wants something in return......mostly the prefered and prefixed outcomes of any research)...they have lost any form of authority because of a failed true scientific system on each and every account.
