Re: Rocket Thrust Is Relative To Air Pressure
Here is another thought. Some people including some scientists believe that the whole universe at sub atomic level consists of pure energy and that what appears to us as solid is an illusion created by the limitations of our minds and bodies. Its something like a Computer which is only designed to run certain programmes and anything outside its limitations cannot be comprehended.

Re: Which Lies Are You Going To Believe?
obviously
in scripture, wood is very often symbolic of Jesus Christ.
Noah's ark, Moses' basket, the staff that devoured the serpents of the magicians, and later budded, the ark of the covenant, the cross.
but it's interesting what your mind goes straight to instead.
again, obviously
the pressure is in the rocket's reagent chamber. substances are combined that produce an exothermic reaction, raising the pressure of the rocket's fuel. these gasses escape out of a nozzle, which is the 'business end' of a rocket engine.
it doesn't need there to be pressure outside of the exhaust chamber at all -- as long as there isn't more pressure outside the exhaust than what's created in it, the rocket propellant exits. just a like a squirt gun works by increasing pressure inside the water chamber, not outside, a near-vacuum doesn't stop momentum transfer from taking place.
F = ma isn't a "massflow equation" lol
that's just the definition of a force. Newton actually didn't state it in these terms, though, he wrote
F = dp/dt
where p is momentum, mv. mass times velocity.
what this definition states is that a change in momentum is a force.
what we have in a rocket is an exchange of momentum: gasses, having mass, exit in one direction at high velocity.
Newton's third law was mentioned -- that's pretty important to this topic. it says:
p[SUB]1[/SUB] = p[SUB]2[/SUB]
or
m[SUB]1[/SUB]v[SUB]1[/SUB] = m[SUB]2[/SUB]v[SUB]2[/SUB]
that is, momentum is conserved. the m[SUB]1[/SUB]v[SUB]1[/SUB] here is the rocket exhaust - the m[SUB]2[/SUB] is the rocket itself, which is generally a lot more mass than the exhaust gasses, so the v[SUB]2[/SUB] that balances the equation is smaller than v[SUB]1[/SUB], but it is a non-zero vector pointing in the opposite direction of the exhaust.
conservation of momentum makes it move forward -- totally independent of any surrounding atmosphere. just like a firehose, actually. momentum transfer, all of which takes place in the nozzle, not in the air around it.

now, i know, pox, from what you've written, that you probably aren't the type who appreciates knowledge and that you have no understanding of physics & how the world around you works. i realize you're going to totally not respond to this and to dismiss it -- if you even bother to read it. but i thought i'd be generous and give you a small education. ignorance kills, and that's what you're spreading - no, worse than ignorance, you're spreading lies and deception - but that's maybe because you're ignorant.
hoping that at least being exposed to the actual truth will have some positive effect.

Did We Land On The Moon? You Decide?
[video=youtube;NbysKQIrVdc]https://www.youtube.com/watch?v=NbysKQIrVdc[/video]
If we didn't land on the Moon, then NA$A lied. If NA$A lies about one thing, why believe anything they say?
There is some very compelling evidence/testimony...if one were so inclined to watch this video.
Peace.

Space Suit Helmet Question?
Regardless of any other debates, arguments, theories, what have you...is it possible for the astronaut's helmet to turn as is depicted in this video?
I'd really like someone to explain how this is possible? And if it's not possible, does this video demonstrate clearly that NA$A is lying?

Its been "1984" ever since tv was introduced.
Just look at the way ppl "go off" when watching their FAV Team playing their FAV sport. (2 Mins of Hate anyone?)
Everyone believes what they hear and see on the tv.
No "actual" proof is required nowdays.
U just need a professionally dressed person in a suit and tie, with glasses...using fancy words + a bit of CGI animation... and BOOM! Everyones eating out the palm of ur hand.
Outta space? Galaxies? Many suns and planets? Spinning Globe earth?
Please!

It is kind of funny how the enemy is so "smart" and tells us what he is up to, expecting us to just roll over and say ok. What it is though is sort of an inoculation to make us expect to see it in the near future so that when the great deception happens even we Christians can get sucked in by it. And the problem is.....In many cases, he is right.
Yea. The enemy always tries to mimic God.
In the same way God said that He would not act.... until He told the Prophets first (and the Prophets spread the word from there) ..... and so, it seems to be the same with the devil and his prophets (aka the elite)
They tend to show us whats coming via tv shows/movies, before they decide to act.

I believe certainly that we can launch both "Space Craft" and various other objects into the earths outermost atmosphere. To go outside of that I rather believe is such a challenge it makes me speculate as to if what we have been told via our media is true, as one is suddenly subjecting anyncraft made to such a force.... Well, let me give an example of this force. Jump into an aircraft, reach 1000 mph and dive into the sea. It is that kind of force you are playing with here just to leave the earths upper atmosphere. Dont believe me? Well, let's approach the same idea in reverse. Some very large formations of rock and ice hit our outer atmosphere each year and the majority get so broken up that it is rare to find fragments on the earth. We all know it takes some huge rock for just a small piece survive to hit the earths surface. Now both ice and rock are normally quite solid objects. The remains that have been found have been very solid fragments, only a fraction of their original size.
Now think what that would do to a man made space craft!
Let's also consider the delicate satalites. They have to be within the outer part of the earths atmosphere or they would be flying off into space. They need to be at a height which enables them to stay in position and yet not get torn apart by the forces up there. A very clever achievement to do that with such delicate objects isn't it?
I write this not just with the question if mankind has entered space or not, but to consider why we would want to? Is it genuinely right that vast amounts of tax payers money is spent on such challenging projects when in ones own country a lack of employment means that so many are living in difficult conditions that their survival is at risk? Wouldn't the money raised be better spent on those that need a help up?
Wouldn't righting wrongs and helping those in a mess make this earth a more attractive place then attempting to reach another planet to populate it with the few richest people?
Another theory comes to mind. What space programs could really be funding. A cover up for long range missiles, bullets, and various advanced aircraft. One could be developing war machines under the guise of peace? Such terms as a country that has entered the "Space Race" could mean something different. Another term... The big secret nuclear arms race.... Is this more of a cover for the more advanced versions of a fuel/air device and as devastating as these are, what they are portrayed to be are many times worse, hence why countries have hundreds stockpiled and not just one or two?
It is good to explore various theories. What is possible and what is not. Even if one does not find out more, it is good to have an open and questioning mind. Even if we go off track and then back to reality!
Over to you.......

They must somehow get more funding by talking this way.
It is all about money, isn't it?
Isn't every thing all about money?
I believe whatever we do in space, it's all within the range that God allows us to go.
Nothing more.
