Greetings, and please forgive my ignorance on the question.
What I am trying to understand is if there is some qualitative limit on producing a "perfect" vacuum.
In other words, let's say that I am in deep space and that I have a vacuum producing piston(by moving the piston away from the "end plate" in a sealed tube, with the other end open of course)
If my piston tube were 20-foot long, I suppose I could do that.
But what if my piston tube were 100-ft long, or 1,000 miles long, or 1,000,000 miles long. Is there a limit?
Thanks
