Proton pump.
The nerve cells create an ambient, standing electric field by moving protons across the cell membrane. The signal is generated when the protons are allowed back into the axon, nullifying the electric field (grounding the bus?) very briefly, first at the triggered end of the nerve...
He who evokes Star Trek in a serious discussion loses.
But...
This discussion smells exactly like ONE Vulcan displaying "intellectual superiority" before a LARGE group of "irrational humans". Not in 'real life', but on TV. FICTIONAL. And not because it makes sense, but in order to illustrate...
A Dunning-Kruger demonstration? Allow me to proceed.
The interesting thing is we have a fairly good view of one galaxy, and are making sweeping claims about all the others, many of which are permanently out of sight.
The other interesting thing is, the word Galaxy might arguably include these...
Seems temporary. And vulnerable to a missile, if someone lacks patience.
How much trouble in tossing a phone pole sized bar magnet very precisely (smart bomb) at the Poles of the Planet? How many would it take to magnetize the planet?
Would't really matter where you set up the factory. Robots...
Air.
Mars has some, the Moon has none. If you are going to try to make something, it's good to have something to work with. Where would Dillinger be without that bar of soap?
It would be better to use a phone to ask someone already there to deliver one of whatever the heck is so damn important.
Trying to think what it might be. FAIL.

Please pick up a bowling ball. Hold it at arms length, head high.
Now, rest.
Does it not upon due examination turn out that YOU, yes YOU, were holding the ball up?
And what happened to the ball? Did it not achieve of it's own volition the lowest potential energy state available...
Not at all.
A car on a hill will roll down the hill. It is the brake, acting continuously, that prevents the car from rolling.
A magnet stuck to a fridge would, if not for the magnetic force, fall to the floor.
In both cases friction, STATIC friction... acts continuously to prevent...
A magnet stuck to a fridge is not at rest. It's just stuck. A car parked on an incline is not at rest. It's just parked. I specifically mentioned that.
And to emphasize, Friction is the force that Resists relative motion between objects in contact.
It can do so successfully. When that...
