But isn't that what the writers did with "technobabble?"
That term wasn't coined until the TNG era. I'm talking about TOS, back when all this started over half a century ago.
Star Trek is not one monolithic thing, but multiple separate works created by different people in different eras. TOS started out with the goal of being scientifically credible, allowing for dramatic license and budgetary compromises. As I said, other than a couple of 1950s kids' shows, it was the first SFTV series that
did make even the slightest effort at researching credible science, and pretty much the last one for quite a while. Later Trek productions have been inconsistent in their commitment to that goal, with some trying to live up to the same standard and others just not bothering.
Early TNG actually had pretty solid science by SFTV standards, thanks to Rick Sternbach and Michael Okuda working as technical consultants as well as art staffers. There's some pretty good stuff here and there. The portrayal of a periodic nova star in "Evolution" was so good you could use it in a science class to illustrate the principle. And "Yesterday's Enterprise"'s explanation of the time warp as due to "a Kerr loop of superstring material" is actually quite a plausible one grounded in real general-relativistic concepts and advanced astrophysics, aside from the misuse of "superstring" to mean "cosmic string." But as TNG and its successors went on, the standards of science declined, and the good science gave way more and more to actual technobabble, made-up stuff like tetryons and veterons and "anti-time."
Large chunks of the science in Star Trek is complete made up, and that's okay because Star Trek is set in a fantasy future, not a scientific realistic one.
Again, that was absolutely not Gene Roddenberry's original intention. That's the result of later producers not bothering to maintain the same effort at credibility that Roddenberry aspired to. His explicit goal in the creation of
Star Trek was to make a show
unlike everything else in SFTV at the time -- more adult, more sophisticated, more realistic both from a character standpoint and a scientific standpoint. And for pretty much the first 20-25 years of Trek's existence, it succeeded in that goal, remaining head and shoulders above the ludicrous, cheesy SFTV that followed, things like
Space: 1999 and
Battlestar Galactica and
Buck Rogers.
It wasn't until the late '80s and the '90s that other smart SFTV shows followed in TNG's footsteps, though they were usually relatively fanciful themselves. And Trek's own commitment to credibility grew increasingly inconsistent over time. So audiences today don't see Trek as any different from the rest of SFTV. It's just another show for you. That's sad, because for a generation it was the best thing SFTV had to offer by a considerable margin. Well, it's not really sad -- it's good that there's so much more quality SFTV now, that it's not just one good, smart show and a bunch of cheese. But as someone who grew up in the era when Trek was the undisputed standout in SFTV, it's kind of sad that audiences today don't realize how extraordinary it was in its day, and for some time thereafter.
