Oh, technobabble is awesome. I love it, but most especially the well-crafted stuff that writers actually put a lot of thought into. Example of the well-crafted stuff, from "Obsession" [
http://www.chakoteya.net/StarTrek/47.htm]:
CHEKOV: Deflectors up, sir.
SPOCK: The deflectors will not stop it, Captain.
SCOTT: That's impossible.
SPOCK: I should have surmised this. For the creature to be able to use gravity as a propulsive force, it would have to have this capacity.
The problem that people have comes not actually from the existence of technobabble at a moderate level, but from its overuse, especially as a means of resolving the plot.
We can stick to "Obsession" to see how it is in fact
not an example of using technobabble to resolve the story. Resolution of the story follows from Kirk's decision to delay the rendezvous with the
Yorktown and risk lives on Theta Seven to follow the creature home, to where Kirk perceives it to be going.
For an example of a bad way of using technobabble, suppose that "Obsession" had gone something like this:
CHEKOV: Deflectors up, sir.
SPOCK: The deflectors will not stop it, Captain.
SCOTT: That's impossible.
SPOCK: I should have surmised this. For the creature to be able to use gravity as a propulsive force, it would have to have this capacity.
SCOTT: Well, just modulate the precession amplitude and catch the bloody thing in a force bubble.
KIRK: Do it.
SULU: Done, sir.
KIRK: Very good, Scotty. Spock, can we compress the force bubble to overcome neutron degeneracy pressure and force an implosion?
SPOCK: Dikironium is inherently unstable, but I believe we can, Captain. Mister Sulu, increase main deflector to full power.
KIRK: Impulse power, too.
(The ship shakes a little.)
SULU: We've done it!
KIRK: Very good. Uhura, drop a warning buoy. Mister Sulu, warp six to the rendezvous. Doctor McCoy, does this fill your prescription?
MCCOY: Better late than never, Jim.
(Everybody laughs.)
See the difference?
