Rockets need an atmosphere to propel

does he work for the nsa? why do you need my location?

We all work for the NSA. Ever heard of Echelon? You can't be not heard.

There.

Out of system yet?

(sorry, but I'd like to be let know when/if my a$$hole is showing too.)

Someone who truly understands what's really going on. There truly is not an em field radiation signature that isn't captured on Earth. Our world is covered completely and you cannot hide from Uncle Sam.Your tax dollars at work ensured that.

I wasn't arguing anything, if you look back through page 6 you'll see I have no argument one way or another but enjoy reading and find it all actually absurdly comical... I'm just saying it may be perceived by some as disingenuous when you append flowers to everything, even in posts that clearly otherwise exude anger/sarcasm/stress/insult/fluster.

also, I haven't "worked" for any taxable income since I began learning of the probably 99% of tax money going toward decption/fuckery many years ago. (around age 18, c.a. 2008)

So no sorry, not my tax $, your's maybe, and given the work history you've claimed here I'd say it's likely, but no not even one bit of mine.

I'm just a giggly observer who made way too much with computers my own way early on.

I wouldn't say I'm a "Alabama University" student either, though I personally think that is probably as decent a school as any these days.

I do have high degrees in mathematics and physics in what are considered generally as top schools in the US, but as soon as they were achieved I began doing my own learning and realized a great deal to be missing / left out of all those textbooks.

So I followed that path pursuing that 'lost' knowledge for a long time, then went back to hard math and computers for a while, then back into the abyss, and so on, until finally winding up somewhat balanced, seeing great truth and validity in both sides. I'm not here to tell anyone what to think only to strongly encourage everyone to NEVER think you know all that is knowable. That's death.

Like I said, I think you're both right, you and OP, and I pray very seriously some day such a revelation encounters you both as well.

In the 'heavens' or 'sky' is unlimited possibility and potential, though no one reaches it by stepping on others.

True. But it’s usually a computer that picks up chatter. Humans only get involved when chatter gets interesting

That's because you're a fucking moron. You already demonstrated you completely missed the point of the video to begin with, I doubt you even watched the whole thing.

No, this one's legitimately and deliberately dense. He's beyond help.

Kicking him to the curb might be the best bet?

Ever village needs its idiot. He's free to be an idiot all he wants.

Will you marry me?

As a newcomer I'll tell you the same as everyone else who questioned my replies. I always will reply with a at the end of any reply in in regards and deference to an original glp member and my dear friend Suzanne who passed early in the early 2000's. I picked that habit up from her and won't relent it until I too pass. Every reply of mine shall always and forevermore l be punctuated by a

Much regards-SOT

ah ok, unaware of back-story, peace

not a newcomer though, here since 2008.

I might cuss your ass out and go to town on you but rest assured you will always get a to close out any debate. Until the day I too die at least.

guess what...NASA is not the rocket designer or builder...those rocket are designed and built by private companies...like Boeing and LockMart… they've been building and flying rockets into orbit and beyond for many decades...and there's nothing you can say that will change that fact. Space science, physics, and orbital mechanics is fascinating stuff, if you can wrap your brain around it.

2008 really? yea you're a neewbi. Been here since sept 1998.

hmmm... well i bet i've been here a larger percentage of my life than you. hehe

Maybe true but I bet I'd qualify as a grandparent if not a great grandparent for you. To me, you're a young whipper snapper. still trying on pull ups after getting out of diapers.

You're half correct. NASA contracted out to rocketdyne and partners, in the early 50's. Currently, they only perfect 80 % of what private companies design as standard.

Makes sense. I imagine I'd feel the same about someone my grandson or granddaughter's age if I had those years.

I'd still not trust my own knowledge/experience/wisdom over the sum of the same between my self and another, I think, even if that other wore diapers.

There are glaring holes in both sides of the 'spectrum' or 'story', that even the least intelligent/experienced/wise among us would find tremendous difficulty in not noticing.

I didn't take physics - wish I did. But I think the nozzle is key, regardless of vacuum: I know how to adjust sails on a
sail boat, which have force exerted on them, and we can
move close to an opposite direction of that force. ??

Not often I've done this.... but willing to concede, it might appear you are redeemable by your reply. For that non argumentative reply I give you credit for being a stand up dude/dudette. Blessings for you and keep it up. Much easier to attract bees in your life with sugar over vinegar.

OP I don't think anybody answered this one so here goes:

When you hold a ball you apply a force equal to what gravity applies to it but in the opposite direction.

When you drop the ball you stop applying this opposing force and the ball falls to the ground.

There is no opposing reaction in your hand when you drop it.

What you were attempting to show with your vacuum cleaner and pipe experiment was the removal of the weight of air in the section of pipe, which you expected to be observable on the scale.

The reason it failed is that for every volume of air you removed from the pipe, more simply rushed in from the open end of the pipe, resulting in no net change in weight, or minimal observable change.

Had you sealed off the pipe and created a true vacuum with the vacuum pump, you may have seen something, but probably not on an inaccurate bathroom scale, due to the relatively low mass of air.

Rockets do work in space. The rocket essentially carries its own mass along to interact with in an equal and opposite way. Onboard is fuel and an oxidizer that expands explosively through the Venturi nozzle, which greatly accelerates the exhaust gas.

The equal and opposite reaction occurs here in the nozzle. As the gas is accelerated downward from the point of reference of the nozzle, the nozzle is also accelerated upward from the point of view of the gas. The nozzle is obviously attached to the rocket and the resultant action is away from the exhaust gas.

They use a similar argument to my example of 2 people falling off a cliff and pushing against each other whilst falling.

"If you stand on a skateboard and throw a bowling ball forward, that force will push you and the skateboard back. However, because your weight on the skateboard is heavier than that of the bowling ball, you won't move as far.

That's the challenge engineers face when designing space engines. Yes, a small amount of thrust does push the spacecraft forward, but it often takes a great deal of fuel to get going anywhere quickly. More fuel means more weight, which adds to the cost of a mission."

A good example is if you fire a pistol in space. The pistol will still recoil because of the gases from the propellant pushing against the bullet.

I would sure like to sell you something that doesn’t work in space if you paid enough.

Now you are making assumptions without proof. With the vacuum cleaner on and pointed close to the pipe, the pressure in the pipe would close to equilibrium with the vacuum hose. Any pressure trying to get in the pipe would go into the vacuum instead as the vacuum maintains low pressure.

Secondly, the initial evacuation, the airflow was strong enough to lift a penny against gravity, but there is no observable force on the scale.
