Cluesforum—Exposing Mass Deception

Imagine now the high pressure emitted by any rocket from its (always open) nozzle. As it enters the vacuum of outer space, the very same - almost explosively rapid - pressure equalization is bound to occur. The rocket will be emptied of all of its pressurized fuel in a flash - by the overwhelmingly...

Here's some more info on the pioneering experiments of the good Doctor Robert Goddard, one of the founders of rocketry: March 16, 1926 Goddard conducts the first successful flight of a liquid fueled rocket . The only problem is that he didn't film it . Even though he brought along a film crew. The e...

2. Objects don't accelerate unless they exchange energy with some other object/field. There are no objects or fields in space (I regard them to be so small/weak as to be virtually non-existent) Dear Boethius, I believe we are saying the exact same thing - only expressing it in different manners. Th...

Allow me to attempt to clear up misunderstandings around some of the salient points of my analysis: I consider "space" to be low-gravity and a near-vacuum . Free Expansion 1. is an effect that occurs when a high pressure gas enters a vacuum. It is not something to be concerned about inside a closed ...

The opening of the crimped case isn't instantaneous so at which point in the opening of the case does the gas change from work-producing to non-work-producing? As soon as it begins to open? Mid-way? Three quarters? All the way? Some point after it is fully open? And how does this translate to a roc...

I would have thought that pushing open the crimped metal cartridge would be considered work but you said no work is done when gas escapes in a vacuum ... That does seem like a contradiction, Boethius. I see a couple possibilities that do not contradict the postulation that escaping gases moving alo...

^ Whatever you say, Boethius. I would have thought that pushing open the crimped metal cartridge would be considered work but you said no work is done when gas escapes in a vacuum so I guess it must be accomplished by magic then. Thanks for clarifying that. Well, lux, yes, pushing apart the crimped...

"Gravity/weight/thrust issues." Exactly my thoughts, Lux. So have we been agreeing all along? :) We agree on many things, Simon, but I am in Heiwa's camp on this one. :) BTW, .22 caliber blanks usually don't use a wad -- they are simply crimped (even those in Goddard's time). http://img835.imagesha...

Great post, Boethius. And I've learned that if we actually want a decent sized vacuum chamber, the greatest two publicly known are both owned by NASA. And the largest is only a couple hundred feet on a side. The second largest is half the volume. So while these might be large enough to test a small...

Goddard's flawed test of the theory of rockets in a vacuum. Physicist Robert Goddard (for whom the Goddard Space Center is named) was one of the first to claim that rockets would work in the vacuum of space. The New York times mocked his ideas in a 1920 editorial. http://en.wikisource.org/wiki/The_...

Just curious: How do we know that "space" is a vacuum? I agree with this question. However, we are only testing NASA's claims that it is. Hey Farcevalue, I've been thinking about this question as well. If space is a vacuum what does this mean for the Theory of Relativity which makes a lot of noise ...

If one of the astro-nots on the 'ISS it or ISSn't it' released a ball of water [that they seem so fond of doing in such a pristine environment where water let loose obviously wouldn't interfere with the electrical items on board...] and then changed the atmospheric pressure to change the state of t...

Disclaimer: Well, I shouldn't have started this because, as I've said, there's really nothing conclusive in these videos. It's also not a major point of mine but videos apparently attract more attention than logic does, I guess. I only meant to point out that I see no indication of support for the ...

Hi Boethius, I've really enjoyed reading your articulate arguments on this subject as well as the challenges and discussions it has inspired. I also understand Lux's frustration with not having something to show that could demonstrate the evidence for it, though. Hello Maat, thanks for the pleasant...

It seems your comments are becoming more and more simple contradictions. Perhaps you could contradict me on one of my main theses? I have. You've simply ignored most of them. Or, perhaps, even, you could do a little research before you post these knee-jerk "gotchas!" Perhaps you could prove ONE thi...
