Such bluster! Rockets work in space. There's no reason they shouldn't. Those who do that for a living have explained to you at length, in great detail, how that happens -- contrary to your misconceived beliefs. You ignored the explanation, because you have no answer for it -- and now you refuse to engage them further, illustrating that you know full well your ignorant handwaving can't match actual expertise and experience. The consequences of rockets working in space have been brought to your attention. You have no alternative explanation for those observations. There is no reason to suppose you actually have any rational confidence in your beliefs at this point.
You demand that your claims be rebutted only in a certain way, and that this certain way is the sine qua non of proof. This serves only to manipulate the rules of debate in your favor. No, you don't get to pontifically dictate the only form of rebuttal that will be universally convincing, since you have no explanation for the examples of rocketry you've already been shown. You must deal with the valid rebuttals your critics choose to deploy. You have demonstrated you are unable to do so. |

What work have you done? You've linked to YouTube videos published by known cranks and simply subscribed to them without the ability to defend yourself or them against even the slightest criticism. If you mean to take credit for the "proof" scrawled on notebook paper at the top of the thread, then why would you imagine anyone would accept it for publication until you corrected the errors in it that reviewers have already found? You don't get Nobel prizes for bad algebra.

Well, its good to know that all intercontinental ballistic missiles will never work as they go trough vacuum. Guess we are safe from nuclear annihilation after all.
Gingervytes, I suggest you stop posting here and go straight to Presidents Trump and Putin with your groundbreaking equation so they can both scrap their respective projects for those nuclear weapons. I guess Trump could use the money to build his wall, and Putin might need more palaces or something. |

Here is a really, really, really simple analogy for how rockets work that our OP may be able to grasp. It's a video of my shower head. It hangs quite loosely in its cradle.
https://youtu.be/ii2rz7Fd11s Watch what happens when I turn on the water. In the version of the world where rockets only work because the exhaust jet pushes against something external to the rocket, what should happen when I put my hand beneath the jet? What actually happens? Why? |

I thoroughly agree. If the subject is rocketry, and a rationale is presented to support some belief regarding rocketry, I and others who are appropriately qualified would be the best situated to locate any flaw in that rationale. But that exercise having any convincing power over the claimant is based on the assumption that the proffered rationale is the reason for the belief. In almost every case of fringe argument, the pseudo-scientific rationale is backfilled against a belief that was arrived at for other reasons entirely. For some it is a bedrock religious belief. For others it is a deep distrust of authority. The statements of experts fail to overcome these, and in most cases can be woven as necessary into whatever scenario the claimant has spun.
Thither the true believers, of course, but what about people who are otherwise rational but are momentarily confused by the pseudo-science? That's where an expert rebuttal can come in handy, but only if the expert is able to distill it into non-expert terms. Some of that happens here. At this point it's worth mentioning that the original Flat-Earthers were admitted trolls. Not the ones from antiquity, but the Flat-Earthers who arose in the modern rational period and flourished a couple decades ago as a tongue-in-cheek movement. The exercise there was to assume the Earth is flat and then use otherwise correct principles of science to concoct pseudo-rational explanations for the various observations that we know follow from a spherical Earth. It's the scientific equivalent of comedy improv, using the tools of science for amusement and intellectual jocularity. And yes, in some cases the goal was to get people actually to believe them -- not because the proponents believed the principles to be true, but only as proof of how "convincing" they were. Nowadays it's difficult to know how much of that Pythonesque sentiment remains in the Flat-Earther movements. After all, the goal of trolling is to convince people that you're entirely serious. So if it looks serious, that's part of the show. But these days it has become convolved with so much other crackpottery and science denialism that it's hard to know just to what extent it's gotten out of control. The bottom line here, and the lesson for this thread, is that the "physics" propounded by flat-earthers derives from a tradition that never meant to take it seriously unless one was amazingly gullible. |

does non-science springs from willful ignorance?
It is not a barrier, I have slipped through it a few time, twice by accident (albeit pointed straight at the ground). The ideas you offer are not science, they are nonsense (like non-science).
It is sad some people can't comprehend space flight, rockets, basic science, physics; then make up fake claims and ignorance based ideas. |

Yes, you did. Gingervytes is letting most of the posts pass in silence these days. He's cherry-picking one or two to acknowledge, but only by way of doubling down on the bluster. It's hard to argue that one's critics have no case when he isn't paying the least attention to the case that's presented.
The balloon car and vacuum cleaner experiment has already been explained. A vacuum cleaner is meant to create flow. That effects of that flow will be orders of magnitude more significant than any effect in static pressure. So how do we create an environment with lower static pressure unconflated with flow? A vacuum chamber, naturally. But he's already precluded that too. He argues the initial expulsion of gas from the balloon spoils the vacuum and provides his push-off anchor. Then practically the only source of inexhaustable vacuum (multiple puns intended) would be space itself. But it's very expensive and impractical to go there and make direct observations. And he won't accept any sort of remote-sensing, arguing that it could be doctored. Ticking off, one by one, the ways in which his claim could be reasonably refuted, he's trying to create the impression that it cannot be rationally refuted. Meadmaker alluded to the ways arguments regarding the fringe ought to be framed in psychology first. Gingervytes is exercising the ways in which arguments can be framed in rhetoric first, science and logic later. What he's doing is a technique that lawyers learn, to be used to zealously defend the interests of their clients when the facts are bleak -- that is, when winning doesn't seem to be in the cards of purely substantive. In law, such things as jurisdiction and venue affect the standard by which the facts will be judged, and the rules by which that judgment is allowed to proceed. Gingervytes is trying to engineer a victory by manipulating the rules under which his paltry smattering of facts will be examined. He is proposing that the only truly probative test would be an experiment he knows cannot be practically performed by us -- even by people like me who have access to an actual space engineering infrastructure. I won't play his game. There is no variant jurisdiction under which the laws of nature -- and the proper understanding of them -- result in the vindication of his claim. The rules of evidence here are absolute, inviolable, and brutally unforgiving. When we apply them to rocketry, we find no reasonable objection to the validity of rocket propulsion in a vacuum. Gingervytes has proven himself completely inept in that forum, reduced to hurling YouTube URLs and cowering in the corner. When we apply those same rules to his purported counterexample, we immediately locate the fundamental misconceptions in the theories he purports. We can easily provide explanations based on correct scientific knowledge that explain his apparently contravening observations. He cannot reciprocate. We show him the observations that result from practical space travel and he once again returns to his corner to hide. In science as in law, explanations for apparently rebuttive observations must ensue in order for the theory to hold. None of that is corrected by frantic attempts to contrive a new rosy framework for probation. |

Indeed, it's one thing not to understand subjects that require concentrated effort to get right. It's another thing to say, "I don't understand what you're saying, but I maintain that you're wrong." Ignorance is usually forgivable. Arrogance is not.
In this case he's failed to provide any line of reasoning that connects the facts explained in his link to the conclusion he believes is supported. In legal terms, he has failed to state a "cause of action," and his "pleading" is thus rejected as deficient in form. This frustrates critics because they have to guess at what new nonsense the claimant believes is somehow self-evident. The claimant is frustrated because he thinks his critics are just being pedantic and evasive when they ask him to elaborate his line of reasoning. Or, more insidiously, the claimant is sometimes trying to draw his critics into a straw-man position which he can then later chastise for rhetorical effect. Yes, there are aerodynamic factors in the transonic and supersonic regimes that affect rocketry. But our claimant has made no actual claim in any regard to it. So there is no need for us to answer yet. |

He argues that none have been observed to work, because the means of remote observation can have been compromised and that no direct observation has been made that can be trusted. Those who profess to practice rocketry are apparently either lying or have been somehow fooled by unknown powers. He argues that the effects of practical rocketry, such as direct observation of spacegoing objects, GPS, or satellite communication and observation are achieved by "underground cables" and "google earth airplanes," with no further explanation. So it's the typical pseudo-religious disbelief backed up by pseudo-religious dismissals and excuses. His posts take the form of science, but without the requisite understanding.

A claimant's silence on a question like that can mean many things. I find it curious that he's relying for his science and demonstrations on a movement whose grasp of physics borders on straight-up fiction. I interpret that as leading to one of two likely conclusions: either he has no inherent grasp of the physical world so as to detect the nonsense in what he's watching, or he's bought into it hook-line-and-sinker and therefore has no interest in a reasoned discussion.

Remember, there's always someone who says, "I can just pop in and explain to this person why they're wrong and then they'll be less dumb,"
Then there's an argument that spans weeks, and the dumb person is no less dumb but the person who wanted to educate the dumb person is much sadder. |

How about approaching it from the opposite direction? If I understand correctly it's your premise that a balloon car moves because of a buildup of air pressure behind it, and not due to the momentum of the air leaving it. In that case, have you attempted to measure the air pressure immediately behind a balloon car, to see if there is enough pressure on the machine to accelerate it in the manner you see?

The willfully ignorant who want to prominently display it will find a way to make any debate last weeks. That was, in effect, what the original Flat Earth Society tried to do, but only to entertain themselves by doing it. They weren't actually ignorant. They just found amusement in willfully pretending to ignore one fact and see how the rest of physical law could accommodate it.
In terms of intrinsic value, however, there is a limit to how much a debate can educate and inform others under the auspice of confronting truly willful ignorance. You can only learn so much about hockey from a boxing match. |

Good idea, but that invites a claimant to measure impingement pressure related to flow, rather than the static pressure he claims is in operation. If you put a scale on the launch pad under a rocket that develops 100 N of thrust, it will register just under 100 N of exhaust pressure on it until the rocket begins to rise. The unscrupulous claimant would then claim this is the cause of thrust, pitting the exhaust against ambient air rather than against the scale plate. The zen of Newton's third law is that the pressure on the scale has nothing to do with whether the rocket will fly.

One of the videos that came up in my youtube feed next to this one was something called "The Tyranny of the Rocket Equation". Since I had just encountered the rocket equation in my class, I was interested.
Fascinating stuff. I had never before really thought about the whole question of why rockets fly. I mean, I knew that they burned fuel to produce thrust, and I knew that the thrust was related to those great big flames coming out the back end of the rocket, but I had never really thought about the fact that the fuel itself was the thing that caused the rocket to move. I knew it, but I had never really grasped the consequences. It didn't really sink in that, basically, a rocket moved by taking something that was on the rocket and throwing it out the back end of the rocket, really fast. That "something" happens to be the fuel, after it was combusted, of course. So, the space shuttle is in some way powered by a really interesting fire hose. Oxygen and hydrogen mix, and some really fast moving water vapor exits the back end. The reason the video was called the "tyranny" of the rocket equation was all about how there was really no way around the problem of carrying, and thus having to propel, a whole lot of fuel. The professor in the class videos had made the same point. It's not just that the engine needs fuel to run. It's that you have to throw something out the back end in order to move. I had always kind of imagined that you could use a nuclear powered rocket to generate a lot more energy per unit mass of fuel. However, the tyranny of the rocket equation is that the only thing you can do with that energy is use it to throw heavy stuff out the back end of your rocket, so all that energy per unit mass really doesn't help you all that much. To Gingervites, Any commentary on that balloon car experiment if performed at high altitude? Or with a second vacuum cleaner nozzle placed in front of the car? |

A simple question here: since it's clear that the abundant evidence of rockets working in space, including photographs of them doing it, photographs by those in them, the work of theoretical physicists and rocket scientists in the field, the testimony of the many people who have taken rockets into space and returned, the operation of GPS and satellite communications, etc. etc. etc. ....what possible proof would work for you? All you have to do is continue to deny evidence and call those who disagree with you liars. What would be proof that you could not deny?
I really am interested in this phenomenon. As far as I can see, the only possible thing that would prove the ability of rockets to work in space would be for someone to put you in one and shoot it into space. I suspect your astronautical qualifications are fairly scanty, so since that's not going to happen, what on earth (or off it) can anybody ever do? |

Well, to be fair, while the OP might disregard actual science and debate, I personally always learn fascinating new things by reading these threads. In this case I got a bit of well-explained rocket science lessons by people actually involved in the field.
So, thanks for that guys |

Nope, wrong again. I can't be bothered to repeat the filming, but I can absolutely assure you that the shower moves not one millimetre no matter how close I put my hand to it.
Rockets are filmed launching from the ground all the time into air that gets thinner and thinner. By your reckoning they should just not be able to do that, yet they do. Either the entirety of the world's specialists in the field are wrong, every piece of media showing rockets working are faked and every eye witness is the victim of some sort of mass psychosis or you are wrong. You are wrong. I'll say it again: your misappropriated statement that gas does no work in a vacuum is not the same as rockets do not work in a vacuum'. |

Video doesn't become more true if you post link to it twice .

No, that's not how it works. We can provide you with countless hours of video showing spaceships operating in space. With a wave of your hand you dismiss all of it on the speculative grounds it "could be edited" and demand more evidence. Your evidence, on the other hand, consists of little more than video demonstrations produced by some of the crankiest cranks on the planet, which you insist must be accepted as real and must be interpreted exactly according to your broken understanding of physics, which you have all but abandoned defending.
We get it. Your video is automatically incontrovertible and everyone else's video must be fake. Do you have any better arguments, or can we draw the curtain of charity over this ludicrous display? |

Hence why several of us have asking him if he's a flat-Earther. He hasn't answered. Either he's shilling for them or has been hoodwinked by them. Neither bodes well for his arguments, but we need to know which it is so we know whether to point and laugh or laugh and point.
