Interesting! Conceptually, I can imagine that the electrons in a fully charged capacitor are dormant and aligned magnetically. However, to produce energy the current flow must produce a magnetic loop flux to move at right angles to the voltage field. There is no problem for jaiii to fire charged gas ions from a satellite to correct its position as Newtons laws of action and reaction force being equal and opposite will apply.

Yes it's all in the coordinates Pete.

I think I could use the idea of a observer, observing the event horizon of a black hole? Saying that for the earthbound observer, according to his clock and ruler, 'time stops' there. If now time 'stops' for the earthbound observer, using his coordinate system to measure it (what happens at the event horizon) by, then light should stop there too, according to his measurements. Or is that a wrong approach to a 'coordinate clock'? My own take on this is wondering in what situation it becomes a meaningful definition? Locally it is simple, 'c' is 'c' as I think.

Well Pete, TNS also draws people without the mathematics, and then it becomes a question of whom you want this page to be directed too.I only show these pages to those whom I believe has the ability to follow them. That's why if you read the opending post I said
.. those of you believe yourself knowledgeable of Schwarzschild spacetime geometry ...
Otherwise you can't give a mathematical proof to those who can't follow the math. To those who don't know the math I just tell them the way it is. Simple.

Yes and this is exactly the point that most people misunderstand. Also things like relativistic beta and gamma are assumed as known in advance.

Personally I prefer the citation where AE is told to have said "You do not really understand something unless you can explain it to your grandmother." On the other hand he also seems to have said "keep it as simple as you can, but no simpler than that." Or something to that matter at least? :)

np, might become a book I will read with interest, don't let 'hard science' boggle down your imagination, though :)
Take it where it wants.

I was actually thinking that, like having asteroids etc be in close proximity frequently, I'd have to think of ways for space travel to be doable for them tho. I'd imagine just launching NOT NEAR THE RINGS would work best hahaha. >.>
I gotta do some research on asteroids and stuff next- ty for the inspiration/pointers!
Picture processing is a very CPU intensive process that may well lead to over heating which could well be the cause of the program hanging, I suggest you install the free temperature checker coretemp_1236 (beware it foists additions on you if you are not careful but no malware).
It is better to do picture processing with a program that runs in the GPU (if you have one) but over heating can often be reduced by replacing the heat compound between the CPU and its heat sink.
