Rockets need an atmosphere to propel | |
InterStellar_Hoodrat User ID: 76465276 United States 01/22/2019 06:33 AM Report Abusive Post Report Copyright Violation | Simple proof, rockets don’t work in space vacuum: get a pipe with only one side open. Put closed face down on a scale. Remove the air from the pipe with vacuum. Where is the opposite force on the scale? I didn’t see it. Quoting: Balance242 Now lets say you put an object, let say a few pennies that weight approx 3 grams each. Now the airflow is strong enough to lift those pennies against gravity. Shouldn’t I see a force greater than the normal force of the pennies? Not sure if Trolling or Stupid, however I'll give you the benefit of the doubt. Your pipe analogy is stupid, The air would be removed and the weight of that air would be reflected in the scale weight, just because their is no air in the tube does not mean the penny is now massless, or can somehow overcome gravity. What airflow are you talking about? its either a vacuum chamber or a low pressure area, have you been taking meds and playing with vacuum cleaners?? Clearly the chamber is not a vacuum when you can see the buildup of smoke. You must be stupid to think a container filled with smoke can be under vacuum. you are a stunning example of the dunning kruger effect in action InterStellar_Hoodrat |

Quoting: Chip I'm impressed GLP. You guys have really have outdone yourselves. I guess that’s why glpers cannot prove rockets working in a vacuum with simple experiment Most rocket systems include their own fuel. There's no need for oxygen or any other needs that the vacuum doesn't provide for a rocket to burn. Do you understand? 2 + 2 = 4. Are you with me? Well if you my initial post before assuming, you would realize I am not refuting the lack of oxygen for combustion. When you assume, you make an “ass” out of “u” and “me” Balance242 |
Dr. Deplorable Astromut Senior Forum Moderator 01/22/2019 01:24 PM Report Abusive Post Report Copyright Violation | Even low earth orbit is a harder vacuum than any vacuum chamber on earth, so yes, it is. There is no "absolute" vacuum anywhere in the solar system, there are always a few particles everywhere you go, but for all intents and purposes, yes it's a vacuum. Are you really this ignorant? |

RiZE User ID: 69139474 Canada 01/22/2019 05:31 PM Report Abusive Post Report Copyright Violation | prove it! I disproved it using simple experiment. Why don't you use simple experiment to prove it. Rockets motors do not push against the atmosphere they push against the rocket body. simple test: put a scale on the pushed side of the rocket motor and measure the amount of force put the same scale on the exhaust side of the rocket motor and measure the force against the scale. The result will always be greater on the side to which the rocket moves (away from the exhaust) because of the effect of the rocket's thrust against the object it pushes through space and the atmosphere. Indeed I agree. There is no force in space working against the rocket so obviously it would be propelled by the rocket engine. What does it even matter? Why not conduct an experiment to disprove something useful?

Now you have to prove that there is, otherwise rockets don’t work in space. Balance242 |

Quoting: Balance242 That's how you get to orbit. The fact it turns around, nulls its horizontal velocity and then comes back to land next to where it started proves very much that it did indeed have thrust in space.

.Rest. User ID: 76853663 United States 01/22/2019 05:54 PM Report Abusive Post Report Copyright Violation | If rockets don't work in vacuum, explain exactly how satellites get into orbit...with details, please. Quoting: hotdogg seems a hell of a lot cheaper and easier than the trillions paid to NAZA and Elong Moist!!! anyway, regardless ... satellites aren't in 'space' - low earth orbit or in Exosphere not the vacuum of space (cos rockets dont work there - despite what Disney and Chicom showed you!) yup... i gotta say after reading whole thread imho everyone is kinda right, and wrong, including OP on both counts. Iff rockets were ever to go to 'space' (as space is defined by NASHA and other space agencies), who knows what would happen? Nobody does, because nobody is able to do so or conceive of it, because it simply DOES NOT EXIST. Nature DOES abhor a vacuum. So do imaginations, it is inconceivable. People are very creative though for sure, clap clap all around, and the rest are... well... sorry, not trying to offend anyone, conversation here has been great, except the senseless and meaningless insults tossed around here and there. it's a small world after all... . . . . .
