Re: Why Rocketry Doesn't Work in the Vacuum

A big problem with rockets in space continues to be how does the gas expelled through the nozzle contribute any force to the system? when: 1. Free Expansion says gas does no work entering the vacuum 2. The Laws of Gasses say gas can't exist in the vacuum 3. The Laws of Gasses say gas can't do any wo...

Re: Why Rocketry Doesn't Work in the Vacuum

Lastly, we all must be careful when using theory to try and define reality or possible reality. Recently, not related to this topic, I have been looking into why an airplane flies and why light refracts in a denser medium. Surprisingly when delving deep into the subject I found that nobody knows th...

Re: Why Rocketry Doesn't Work in the Vacuum

Same goes for a ship in space. You can combust all the gasses you want. If you don't generate an external force you're not going anywhere. People say "the ship is pressing on the gasses" but the gasses don't exist outside the ship. Gas doesn't exist in the vacuum. So the ship is left pressing again...

Re: Why Rocketry Doesn't Work in the Vacuum

Boethius Thanks for reply and responses. The hamster ball for bees? Not sure. May have been a comment on this from howthingsfly online. http://i.imgur.com/BvM5Lze.png It says, ‘one things goes one way…’, which is about as far as the science of space travel has got here. The science of no-space trav...

Re: Why Rocketry Doesn't Work in the Vacuum

The entire space industry is a massive and ongoing fraud. It's kind of like a lie that was told that was so big that nobody can untell it which is the way frauds like Bernie Madoff explain how they ended up in so deep. The space industry is marketed as science yet it's impossible for anyone not inv...

Re: Why Rocketry Doesn't Work in the Vacuum

1. Newton did not consider gasses, nor their effects, when developing his laws. NASA believers need to address the fact that gas does not exist in absence of pressure. As such Newton's Laws can't be applied to gas in the vacuum. I'm no scientist but it makes sense that gas does not exist without pr...

Re: Why Rocketry Doesn't Work in the Vacuum

Getting back to rockets in the vacuum: It is interesting to see how often NASA supporters claim those who challenge rocket theory are Newton-cconfused, or worse, when in fact NASA space science seems to forget that: 1. Newton did not consider gasses, nor their effects, when developing his laws. NASA...

Re: Why Rocketry Doesn't Work in the Vacuum

I think the main point that the posters on this thread (who are more scientifically minded than I) have been making is that the vacuum itself exerts a force of its own that renders nil the force of the mass of gas escaping from a rocket's nozzle. To use a simple analogy, think of a rocket and its e...

Re: Why Rocketry Doesn't Work in the Vacuum

Fascinatingly mainstream web site which fails to debunk Boethius' formulas, and which in my browser has disabled the copy-paste functionality of a normal web site. http://www.braeunig.us/space/propuls.htm I would like to have a conversation with the braeunig folks. From their site: Consider a rocke...

Re: Why Rocketry Doesn't Work in the Vacuum

Simon, what you are talking about is achieving orbit rather than operation in a vacuum. I locked the thread since the discussion became more about getting things up to the vacuum rather than the science within the vacuum. Why is this pertinent? Because, presuming we are already In the vacuum in a s...

Re: ENDEAVOUR - and the spaced-out NASA efforts

* HOW DID THE SHUTTLES ACHIEVE ESCAPE VELOCITY? The Space Shuttle, weighing 2million kg at launch, apparently used the most advanced liquid fuel (hydrogen/oxygen) propellants known to mankind - with an exhaust velocity of 4.4km/s .(15.840km/h) NASA told us that a Space Shuttle would detach itself f...

Re: Why Rocketry Doesn't Work in the Vacuum

Heiwa, I decided to address the remainder of the points made in your previous post. Vacuum is evidently not solid, fluid or gas as it is empty nothing with no mass so I agree it is difficult to apply a force on vacuum. Difficult? How would you propose one can apply force on a vacuum? But vacuum is f...

Re: Why Rocketry Doesn't Work in the Vacuum

The Straight Dope example is debunked without even mentioning that gas (rocket exhaust) is not a solid (medicine ball). It doesn't matter if a mass m is solid, fluid or a gas. It matters because gasses can't exist without being under pressure. Same goes for liquids. There is no gas floating around ...

Re: Why Rocketry Doesn't Work in the Vacuum

Sometimes I look around the web to see how people are defusing the "do rockets really work in space?" question. It's generally pretty easy to debunk examples of how rockets work in space, that is after I filter out the ad hominem attacks. Take this example from The Straight Dope [/b] Wearing ice ska...

Re: Why Rocketry Doesn't Work in the Vacuum

Heiwa, it appears, has spent years calculating the forces and fuel requirements for rocketry. Now someone comes and tells him that all of those forces are, in fact, 0: no need to calculate fuel expended. Why calculate the number of reindeer needed to pull Santa's sleigh when Santa doesn't exist? He ...
