He hasn't admitted it, if that's what you're asking. He's been asked several times point-blank whether he is, and he has ignored that.

I'm a little bit curious about how they determined the exhaust velocity. Was direct experimentation done, or did they use textbook values? And what textbook, if any, has that information?
Of course, even if the thrust is sufficient, there are practical problem. For one, I don't think exposing certain parts of ones anatomy to vacuum, as would be necessary to accomplish this, would be a really good idea. |

I want to know how Gingervytes would summarize it.
from what I can see, this video from Flat Earth Talk covers the basics of what Gingervytes is trying to say: Scientist Shows Proof That Rockets Do Not Work In The Vacuum of Space
This video is amusing as well: https://www.youtube.com/watch?v=ZcW5B0C3fCw
I have never encountered ANYONE arguing that rockets can't work in space who wasn't doing so for a religious motive. |

Jay I admire your tenacity and your knowledge of space activities, since it is your job along with sts60 to design and maybe monitor hardware that is launched into space. I'm sure that the willfully ignorant Gingervytes disagrees with reality because he has taken in a rather stupid concept(maybe a couple of them). I called troll a few pages back and quit the thread posting. I still keep up with the nonsense though. As you may recall I'm an "underground" type engineer that does not possess the rocket science which you guys know. I can tell you that Gingervytes has NEVER pointed a satellite dish at the shy with what is called a "bird dog". For those that aren't familiar with that device, it measure the reception strength from a geosynchronous communications satellite. You twist/turn/elevate the dish until you have successfully pointed it at that satellite, even from 200 miles offshore in the gulf of Mexico. Then the rig has communication Internet/TV with the rest of the world.
I'm an old dog that didn't know there were two separate forces to the rockets thrust and I did learn that from this thread. Again I'm done with this troll keep up the good work all you aerospace engineers. |

and if my aunty had balls she would be my uncle.
What is your evidence for there being 'two of them'? If you make a claim like that you need to support it. Just to help you on the way. If there were 'two of them' when and where was the second one launched so that it wasn't noticed by anyone? |

This gets us back to the Flat Earth conspiracy. In order for the Flat Earth delusion to be arguable you have to assume a massive, global, conspiracy to conceal the alleged "evidence" of a Flat Earth. You rarely get an explanation for the conspiracy beyond vague notions of "denying God" or "denying proofs of supernatural." This a fundamentally stupid argument for a variety for reasons. For example, it would mean even overtly theistic countries were part of a conspiracy to conceal proof of the divine!
Since Gingervytes is so blatantly parroting Flat Earth talking points it's reasonable to conclude that their "evidence" of a conspiracy amounts to no more than the assumption that there MUST be a conspiracy to explain their underlying ideology. The only "reason" for the conspiracy is that it is a prerequisite for their theology. |

The same as with the first video. Read the comments - why I should repeat something what about 50 people said already?
All the comments, including diagnosing the author with a steroid-caused brain damage, are correct. I would probably just point at the fact, the people who correctly identified ground effect for the drone raising with the cardboard used a wrong explanation for that phenomenon. The "Air Cushion" misconception is quite common among pilots. Find more from some sources dealing with aerodynamics of a wing. |

Actually, probably not. The motor would run without load producing very little heat that would probably be safely radiated out. The motor would more likely over-rev and disintegrate as series motors (used in vacuumcleaners) do. Anyway, we do agree on the "worse than useless" point. Jut nitpicking mental exercise.

Gingervytes, a while back I asked a serious question, which I think could be answered seriously and honestly, if you cared to. You have demonstrated an unwillingness to accept any of the evidence provided by anyone here, or photographs purportedly made by people who flew into space and returned, and so on.
So I repeat my question: what, if anything, would be acceptable as evidence to you? So far you are playing a game of waiting until someone comes up with a suggestion, and then rejecting it. Instead of playing that tired old game, why don't you say exactly what would satisfy you? Not what won't. What will. If you want to be taken for someone who is honest, you need to be honest. This has not so far been in evidence. |

So, and someone correct me if this is too simplistic, if a rocket is in space and shooting gasses out of a nozzle at one end, and we accept that every action has an equal and opposite reaction, what could the rocket possibly do but move in the opposite direction the hot gases are going? What other reaction is possible?

The answer to your question may be that conspiracy theorists are more likely to engage in conspiratorial behavior themselves. There are also some interesting (but not enough) studies linking believing in conspiracy theories to petty crime. To think people would engage in perpetuating a lie on the scale described in OP might be because the believers don't see anything wrong with similar behavior themselves. There aren't that many studies yet but it's an interesting idea. |

How many documented and observed rocket launches do you think there have been? And what do you have in opposition? A couple of crank YouTube videos, a fair amount of ignorance regarding physics, and piles upon piles of unsubstantiated claims of large-scale conspiracy.
Yeah, we win. |

You can’t prove it with actual science so you only have rocket launches, where the rocket isn’t even seen going into space, as proof. Don’t you think that is pathetic?

Except that I did, and linked it twice so that you wouldn't miss it. You keep pretending it doesn't exist.

All your scientific proof is debunked. You have no simple experiment. I have already used simple experiment to disprove an equal and opposite force from gas movement due to pressure gradient force. https://www.youtube.com/watch?v=AubIFUsq7Ss
There is no unedited video of a rocket going into space. You simply have no proof. |

Not by anything you've shown here.
Again, you have suggested that I'm a liar who is taking money to knowingly conceal the truth. I grow tired of asking you to prove that. I dare you to prove it.

I don’t claim any of that. I am claiming that rockets don’t work in space
