That's just the issue, dear boy. You CAN'T produce the calculations to prove it .....
Ironically, you've highlighted the part of physics that proves it was possible.
Shot oneself in the foot, me thinks.
Debate over - believe what you want to believe, but please don't try to misuse facts of...
a) many govenments choose to spend their money on things that citizens disagree with - USA is no exception
b) no need to return - nothing to gain, race to the moon "won", new projects more worthy of limited funds available [Beagle / Voyager / Shuttle / ect]
c) with NASA being some 300,000 staff...
Sadly, even with that much power, Van Allen Colinz will argue that his calculations will prove that there was never enough fuel at that power to wight ratio to go all the way to the moon and back again without a top up on the way.
If you read up on it, they acually used orbit speed around both...
I love the way Van Allan Colinz picks and chooses which bits of physics to throw into his arguement and which he chooses to ignore.
I've been to Cape Canaveral to see the NASA site - those Saturn rockets were very very big. Recognise that a huge propotion of the fuel required, for Saturn or...
