I'm sure that someday the word vacuum will find a new place. As a mechanic. I never used and was not aware of the use of absolute pressure. As far as empty well, I believe that in time we will find that it is not necessarily true either. 100 particles Per cubic centimeter. Does not sound empty...

I don't mean to imply that we could use my shop compressor in the zero pressure environment of space. I am just trying to get a conversation started in the direction. An external combustion engine is a compressor of sorts. I don't really like using the word vacuum when talking about the...

Is space a vacuum for just the lack of pressure?

I am very ill and at this time very tired. I hope I have given you something to think about. I will rest and check back later. Don't let the way things are. Stop you from seeing the way things can be

The air compressor in my garage forces atmospheric air into a sealed chamber until enough air is in the chamber to produce the required pressure. Why can you not pull air/space from outside the vehicle and force it into a chamber until pressure is achieved. I understand that with conventional...

Maybe the words that I use do not exactly fit with your way of thinking, but it is the way I think. I am in complete understanding of how a rocket engine works in space. Thank you for all your input and I do apologize if my lack of technical knowledge offended you, that was definitely not my...

My experience as a mechanic teaches me that I can bring a pressure down to a vacuum, and vice versa. Why can I not do that in space

I think I understand. The gases expand equally in all directions. The Rocket being the only mass around the expansion is pushed by the expanding bubble. That makes sense.

I apologize but I do not know the accepted term. As I wrote, I am not a physicist. I am trying to understand how this works. I know how a jet engine works, I worked on many gas turbines in the military. I guess what I don't understand is that if the expanding gases are pushing against the...

That changes my understanding a lot. Thank you

So you are saying that inside the atmosphere. The expanding gases push the rocket forward but outside of it the loss of mass is pulling the rocket?

Yes, I understand that it takes a greater action to create a reaction. That just makes sense since you are notOperating within the atmosphere. It would take a greater action to create the same reaction. But you are in fact compressing the space

I guess my confusion lies in propulsion. Not fantasy, real propulsion. If space cannot be compressed then what do the expanding gases push against to gain propulsion( forward motion). All systems currently in use as propulsion in space rely on the expansion of gases that are directed in one...
