Good evening & shut up.
For Lo! It is I; Papa Legba, returned in all my splendiferous eloquence, armed with a mighty Staff - made of Truth & the size of a House - that none but I can wield...
The subject of False Analogies has been much on my mind of late; why are NASA-cultists so fond of them (Australia lol)?
& why are they so blind to them?
Research was needed; so I dug deep into the guts of the Great Working that is NASA until I finally found the origin for the Cultists obstinacy.
& that is because the entirety of NASA's space-mythos is founded upon The Mother of all False Analogies...
Time to raise my Fearful Staff of Truth & Smite this Foul Deception to Smithereens!
NASA explain their model of how rockets work via the following Analogy: A man stands on a skateboard, holding a medicine ball.
The skateboard represents the rocket, the man represents the rocket motor, the ball represents the rocket exhaust.
When the man throws the ball, he travels backwards; this represents the rocket throwing the exhaust mass, thus producing an action-reaction pair according to Newton's 3rd.
However, this is FALSE.
In fact, it is the man's ARM, in throwing (i.e. imparting THRUST upon) the ball, that represents the exhaust; whilst the BALL represents an external mass such as the atmosphere.
Thus, we see the true placement of the action-reaction, Newton's 3rd, pairing is between Exhaust & External mass, NOT between Exhaust & Rocket motor; in fact the latter makes no sense whatsoever if considered logically.
Want more proof? Imagine the man & his ball suspended from a rope, so he throws the ball DOWNWARDS (after all, rockets travel vertically do they not?). When he does so, little effect will be seen, yet lower him so that his ARMS can touch the MASS of the ground & he will be able to THRUST himself up, producing LIFT.
Ergo: rockets require an outside mass in order to function, so cannot work in a vacuum.
Space travel is a physical impossibility.
You can howl, nitpick, cry, abuse, deride; but whatever you try, nothing will change that.
I told you before: I am not here to 'respond' or 'debate'; no, I am here to open doorways.
Enter; do not enter; the choice is yours.
Just remember the immortal words of the great Stanley Laurel: 'You can lead a horse to water, but a pencil must be led'.
What are YOU, space-cultists?
Horses?
Or Pencils?
