Scepti, you claim that as long as there is no atmosphere, you can't push anything, you can't get "leverage", as you say. Why? What's so special about the atmosphere?
Hopefully you'll pay attention.
What is special about the atmosphere as opposed to the fictional vacuum of space is, the atmosphere is made up of matter with no free space between each molecule of it, or whatever you want to call each piece of it.
These molecules are extremely densely packed or are expanded, depending on where in the stack these molecules are.
Regardless of whether they are densely packed or expanded, they NEVER separate to give off any free space between them.
This is why we can move within them because we are them. We are not free of them either. We compress and expand in them as they do within themselves.
In your fictional space vacuum there is no molecule medium for anything to happen. It's what would be described as a place where suspended animation would occur, kind of thing.
You cannot have SCATTERED particles just floating about with free space in between. It's not how reality works. It's fantasy and should be seen as such.
This is why things cannot be placed into a vacuum. No rockets or humans or anything, because it does not exist.
Low pressure at elevation is a reality. It's EXPANDED matter/molecules that expand to take up more space per molecule than below.
It's because it's stacked from the bottom up and each time the atmosphere stacks up, it becomes a little bit more dense below.
You are alive because your body is reliant on being squeezed. Your molecules are kept together because your body is under pressure. You are dense (no offence) and you create a dense resistance against a stacked atmosphere that is upon your body frame.
The air you breathe is all attached. You don't breathe in random particles. You breathe in molecules that are all stuck together. You never break them, you just change the make up by expansion or contraction due to vibration/friction as your energy of your body resonates to a frequency.
Look at my avatar. Look at the layers. Imagine that gobstopper/jaw breaker being one molecule of dense matter.
That gobstopper is solid but it can be peeled apart by taking off a skin at a time. To do this you have to vibrate it at frequencies than enable certain parts of it to release.
Let's say we simply peel off the top skin. That top skin will go from expanded taking its place on another gobstopper that has less layers or be jammed between those that have similar layers...but it will always be attached to one or the other.
Once that layer is taken off it creates a surge. It creates a pressure difference. A push into other molecules.
This is the basics of basics and even saying that, it requires serious thought. Anyone that decides to go into frenzy mode. Forget it, seriously.
The genuine people, come in and try and understand what I'm saying, because if you do, you will understand why the global Earth and space is complete and utter brainwashing..as well as much of mainstream indoctrinated so called science theories.
