Han poking at the hyperdrive (backup or regular) to coax it to Bespin makes sense in context of the movie (much like coaxing a car that keeps stalling).
The biggest argument in favour of the "backup hyperdrive" is from TPM: we've seen how big a hyperdrive unit is, even for a rather large vehicle like Amidala's blackbird, and it's shockingly small. It's like the size of a large plasma TV, which makes it more feasible for Han to be carrying a backup unit. However, it begs the question of why he never even mentioned the possibility, since a fully functional backup unit should be just as fast as the regular unit (indeed, one must wonder why the backup hyperdrive should be inferior in any
way to the regular one if the damned things are so small). But of course, Han being Han, he would have used it years ago, and freed up the space so he could store more contraband.
BTW, I think the confusion over dimensions comes from it as a word that describes both "Alternate Reality" and "component of reality (length, width, depth, time, etc). Explanations to simple non-math people like me of certain aspects of string or quantum theory don't really help matters. Although, aren't there theories that gravity is a force that exists pan-dimensionally? Would a hyperdrive need to circumnavigate that along with the aspect of relativity that prevents FTL travel?
Even if gravity extended into this other dimension, so what? All you have to do is move farther into the dimension, and you avoid it. It's like avoiding a tall mountain by simply flying higher. The real problem is that it doesn't cut your traveling distance at all, especially since EU hyperdrive is defined as coterminous with realspace at all points. This means that hyperspace does not solve the problem of FTL travel at all
. It would be more useful for avoiding detours in flight, ie- allowing you to make a straight flight despite obstacles, much like an aircraft can fly in a straight line from point A to B while a car must travel a winding road.
Hyperspace as defined in most of the EU is literally written as a meaningless escape clause from reality, which is a habitual behaviour among idiot sci-fi authors.
The whole thing could be retconned by saying that both
statements are true: the ship must go tachyonic in order to travel at such great speeds, and hyperspace actually refers to the complex-number regime where the ships push most of themselves when they go tachyonic. However, the remaining real-space component and the limited submersion into hyperspace still means they can't go through extremely dangerous phenomena such as suns or black holes, although they might be able to pass through something like the Alderaan debris field without damage.
