The galactic barrier doesn't make much sense, as the galaxy doesn't really have some demarcation point as to where it suddenly ends, anymore then our solar system does. Also with later history of trek the Valiant getting that far doesn't make a lot of sense either, unless you employee some kind of wormhole or accidental transwarp conduit. But its canon. it has to be there.
The barrier didn't seem to be a problem for the Kelvans. IF the barrier doesn't permit electromagnetic signals from getting through why can we see other galaxies from Earth? If the barrier is visible, why didn't astronomers notice it before WNMHGB. One of the few answers would be, the barrier is new, and no one has time to see it yet (of course in Star Trek, things like supernovas effect other worlds apparently at superluminal velocities, and you can watch Vulcan be gobbled up by a red matter black hole in real time from, speaking of WNMHGB, Delta Vega.
It makes no more sense to me than the spore drive. An actual multiversal spanning fungus makes more sense then either of the above, though I don't understand how that is suppose to allow instantaneous travel. But it's no more more insane than genesis device or transporters or warp 10 salamanders.
Yeah, there are a lot of things in the whole franchise that don't make any sense.
But this isn't about the TOS episode but the one from TNG with the Traveler.
