Do cathode rays or electrons in particle accelerators count?

OK lets restate the initial problem without the set velocity but make the distance between the points 1 Planck length with the time for the journey still infinite. How do we proceed?
Consider your response "For instance, you can leave point A at any finite velocity headed away from point B, and never get there." is this the correct view of infinity. That you can't even head in its direction let alone get there.
ChiralSPO: I appreciate the explanation attempt however there is one problem, it's that the box would be need to constructed of such material that nothing could go through it. Many perceived impermeable materials can be penetrated by the likes of subatomic particles, light, etc. Also, if that box is truly sealed, in the absence of any compelling factor, there should be no movement because any alleged vacuum would make that an impossibility. Maybe I'm missing how this applies to either thrust in space or the existence of any vacuum.
Followed your second link. It makes no mention of electrons or positrons, so I don't see how it supports your assertion.An ion contains electrons! Everything melts!
I still don't think this applies to electrons. They say "everything melts", but "everything" is still just nuclei, no electrons involved. Are there studies where they use only partially ionized nuclei?Yes, gold ions, lead ions. See this RHIC article.
You've missed the mixed doubles nuance. No matter how evenly matched they are, one side wins the game. Until one side wins, our universe can't sustain planets or stars or galaxies or life or anything. Then whichever side won, we call it matter.
...Hydrogen is both, antihydrogen is both. Each consists of a particle and an antiparticle...
...But the electron and the proton move towards one another. It's like they "want" to annihilate, but they don't "fit".
nobody gets concerned about the mystery of the missing L-glucose.
I agree that it seems the simplest way to store hydrogen is in compounds such as hydrocarbons. It wouldn't make sense to do it in a car, but we have the technology to react hydrogen directly with CO2 to make hydrocarbons...
the numeral "1" originated as a tally mark ... http://en.wikipedia.org/wiki/Tally_marks
the numeral "0" , represents an empty container with "nothing" in it.
One of the ancient writing system in the world – Kannada shows the origin of both symbols:
1 is represented as arc, while 0 is represented as circle
Blow up a balloon. Keep the end closed. No forward movement. Let the hole open, you get forward motion. You get it because the air inside is being expelled outside. Use the air inside as analogy for the spend fuel. Without exhaust it goes nowhere.
Seems to me in an alleged vacuum that air would be expelled, but just kind of dribble out the end.
