the high-flying tale...
Most fairy tales begin with 'once upon a time...' There Was a Rocket.
After all, on January 13, 1920, the New York Times editorialized, in a
reaction to a research paper published by Robert Goddard, that ”a
rocket will never be able to leave the Earth’s atmosphere.”
My key point?
Space rockets, among other things, are, indeed fantasy.
Why Rocketry Doesn't Work in the Vacuum.
... In any case, it should be obvious that when air/atmosphere gradually
thins out and eventually goes missing altogether(vacuum), no more
counter-force (as of Newton's laws)is available for the rocket to keep
ascending. Much like a dolphin jumping out of the sea - and briefly
flying before gravity brings it plunging back into its own, denser
ambient for which it was 'designed for'. Just like a rocket attempting
to leap into the void of space.

This is the essence of science. You don't really know until you run the
experiment. Until then all you have are hypotheses.
As far as I can see nobody, not even NASA, has ever run a serious space
rocket experiment. Where are the zero-gravity vacuum chambers big enough
to fly rockets? There's a 17-mile long supercollider but the largest
vacuum chamber is 120 feet.
And nobody can ever go out and investigate NASA claims around rockets in
the vacuum independently of NASA.
Space science is like a cult run by ancient priests who speak to the
Gods in private. We're not supposed to think for ourselves. We only wait
until the NASA oracle tells us the great truths divulged only to them.
This is not how science, nor modern, information-based, educated society
is supposed to function. The goal of education is for us to learn how to
figure things out for ourselves; to examine, to evaluate and to reason
with the facts and data. What good is that training if, in the end, we
can only shut up and believe what we are told with no proof, no solid
theory behind it and no way to check the results or repeat their
experiments ourselves?
Rocketry is not unique in this regard. Pretty much all the big results
in science follow this pattern. Anyone who challenges the status quo is
labeled an "idiot" or a "religious nut" which is ironic because science
is behaving more and more like a religion based on faith and less and
less of a method based on observation.
Who was it who said : "The art of thinking and reasoning in strict
accordance with the limitations and incapacities of men misunderstanding." ?
A big problem with rockets in space continues to be
how does the gas expelled through the nozzle contribute any force to the
system?
when:
1. Free Expansion says gas does no work entering the vacuum
2. The Laws of Gases say gas can't exist in the vacuum
3. The Laws of Gases say gas can't do any work in the vacuum
(note that 1., 2. and 3. above all agree with and support each other)
If the gas expelled from the ship in space produces no force how does
the ship move?
First, there should be a theoretical reason why I am wrong/mistaken
about how gases work in the vacuum or how they are used by the ship.
Second, there should be reasonable experimental evidence that supports
the above theory. Pictures of the Space Shuttle don't count.
Come on Rocketry believers / NASA supporters. Show me how I have been
mistaken. Can you do this using science? Without strawmen and ad hominem
arguments? Let's stick to gases in the vacuum, please. That's where my
doubts stem from.
Why I don't think anyone can answer me: In my opinion, space rocketry is
unproven, unscientific conjecture. A fantasy world that has captured the
imagination of many and led otherwise rational and intelligent persons
to abandon logic and fall under its spell, which is pretty much the
story of "advances in science" in the 20th century. Engineering has done
pretty well for itself, but science seems to be going backwards.
I'm often finding that the 19th century was the last time experiments
were conducted which produced results going against our esteemed
priests' doctrines. They locked down science pretty well after that.
I feel like I am at the renaissance of 16th century reason. We're doing
a good job at calling out their bullshit. The next step is doing a few
experiments of our own perhaps.
around or just after the turn of the century, a number of scientific
disciplines were "locked down" through the adoption of paradigms to
which all future research would have to conform. Anthropology and
archeology are particularly gross examples. These paradigms have since
served as "knowledge filters", preventing alternative world views and a
lot of solid facts and findings from being evaluated, published and
discussed by researchers and laymen alike.
