Here is some more physics crackpottery from a century ago:
Source: Simon Newcomb, The reminiscences of an astronomer, 1903, pp. 381, 383-384 -- at books.google.com
He had a lot of experience with anti-gravity crackpots, like one who seemed very indignant at its acceptance, starting a long and impassioned speech with "It seems to me that the astronomers of the present day have gravitation on the brain". But he once encountered one who was relatively reasonable:
AGCP: I would like to see Professor Newcomb.
SN: Well, here he is.
AGCP: You Professor Newcomb?
SN: Yes
AGCP: Professor, I have called to tell you that I don't believe in Sir Isaac Newton's theory of gravitation!
SN: Don't believe in gravitation! Suppose you jump out of that window and see whether there is any gravitation or not.
AGCP: But I don't mean that. I mean --
SN: But that is all there is in the theory of gravitation; if you jump out of the window you'll fall to the ground.
AGCP: I don't mean that. What I mean is I don't believe in the Newtonian theory that gravitation goes up to the moon. It doesn't extend above the air.
SN: Have you ever been up there to see?
(There was an embarrassing pause, during which the visitor began to look a little sheepish.)
AGCP: N-no-o
SN: Well, I haven't been up there either, and until one of us can get up there to try the experiment, I don't believe we shall ever agree on the subject.
(That ended the conversation)
