I find it fascinating how half a dozen more or less intelligent people desperately try to talk sense to a bully who doesn't care for content at all but is just flinging poo in every direction and delights in the attention he gets through that ...
... I hate to tell you all, but PL is the only winner in this thread.
Papa Legba is the winner because he's being realistic. He's trying to tell you that rockets do NOT work in your space and instead of sitting there and thinking about all of what has been said by Papa and a few other's - including myself, you want to try and flex your supposed scientific prowess.
Instead of fighting the fight, try and clear your mind of the absolute garbage fed into it - for now - and look at what and why things are said that goes against mainstream indoctrinated so called science.
You will never gain a serious questioning mind of you carry on being a mainstream YES person who simply follows the masses under severe peer pressure, because life is so much simpler, doing so.
Now, just to get back to the simple basics.
Rockets work well in atmosphere, especially dense atmosphere. They use up their fuel in short order due to the continuous burn required at FULL thrust against atmospheric resistance/barrier to push the mass of the rocket vertically into the sky.
Search your brain and find the part where common sense and logic is hiding, because it's there, so grab it and use it.
Once you do this, you will see how silly it is for a supposed space rocket to have an internal combustion chamber to supposedly propel it vertically into the sky.
Understand that an internal combustion chamber (liquid fuel) is only worthwhile for operating something mechanical like a propeller or drive shafts - you know - stuff like that.
So the simple logical, common sense thought on rockets should be used to see that what is ejected out of it, MUST hit a barrier, CONSTANTLY, for that ejection of fuel to have any effect on pushing a rocket into the sky.
Now here's a really simple analogy of how a rocket stacks it's ejected burning fuel against atmospheric resistance.
Think of a telescopic aerial on a car. Notice how that aerial gets thinner and thinner as it opens up. Why is this?
It's because the higher something goes, the stronger the base has to be and the stronger each section has to be as it rises.
Think of that aerial as a rocket taking off and expelling it's fuel against atmosphere. You see a thicker plume at the bottom that sort of builds like a thinning tower of exhaust.
It's like a telescopic aerial just constantly opening up until the fuel is spent or energy ceases.
That's a simplistic analogy and I do realise that most tefal heads do not do analogies because they are too basic and simplistically logical to decipher.
Anyway, in a nutshell, space rockets are for the TV and fantasy comic books, etc. The prison you are locked into is not such a bad place, even if you can't escape it. It would be a better place if we didn't get lied to all the time and made to believe in amazing bullshit and also scare tactics employed against us, day after day.
I think I've covered the basic.
