So; we have learned that yes, shills do indeed claim rockets work in a vacuum.
Even though such a claim would mean they violate the concept of Conservation of Energy.
Which is the 1st Law of Thermodynamics btw...
Not the 1st Theory of Thermodynamics; the 1st Law.
And violating the 1st Law of Thermodynamics is the Physics equivalent of Rape, Murder & selling 10kg of heroin to a minor, or suchlike heinous depravity...
SERIOUS SHIT in other words.
However, as I have provided solid evidence elsewhere that this forum, & the internet as a whole, is run by military-industrial criminals, expect a riot of mad bullshit disinfo-spam, plus a forum slide, to attempt to hide the crimes I have so easily exposed using simple science & logic.
