In the Star Wars universe, everything technologically seemed possible, i.e. and not limited to: members transplantation, interplanetary travel, holographic communication, supreme medical capabilities (Vader), gravitational levitation, artificial intelligence etc..

Bottom line, any thing from our technological fantasies today, literally existed.

Have there been any evidence in the Star Wars universe of situations where there were technological challenges, or any mention of technological aspirations that didn't exist at the now and the then, where the characters were hindered?

For starters their medical science wasn't able to cure Padmé's "broken heart" – Valorum Feb 26 '14 at 0:04

Off the top of my head, their lightsabers seem to have a relatively limited battery life. On several occasions we see Jedi turning their lightsabers off (presumably in order to preserve the battery) rather than running them constantly.

Additionally, their holographic technology seems quite clumsy. The images projected are translucent, blue and seem to flicker violently.

Help me Obi Wan

Their scanners have limited range and are easily blocked

It's a trap!

Their automatic doors tend to stick when opening:

Their medical technology is insufficient to cure someone who's "lost the will to live":

Oh, and what the heck is that wheezing sound coming from Darth's suit?

I always thought the frequent turning off of lightsabers was more of an OSHA thing. – joshbirk Feb 26 '14 at 0:30
Lightsabers' batteries don't drain unless they're actively cutting something. Qui-Gon was meditating, turning off his lightsaber was almost certainly because of that. – Kevin Feb 26 '14 at 0:31
Some awesome answers there. Just a note about the lightsabers: while I agree that sounds like a likely explanation for turning them off, according to the wookiepedia entry for the lightsaber, the Sith were credited with an energy-saving modification which carried in to future designs: "With this modification, the power cell would only expend power when the energy loop was broken, such as when the lightsaber cut something". So power usage while the blade was active is probably minimal, or non-existent. – Paul Richter Feb 26 '14 at 0:31
@joshbirk Lightsabers do run on batteries, at least in the film novelization. – Mr Lister Feb 26 '14 at 8:25

Probably the biggest "sci-fi" technology that does not exist in Star Wars is Time Travel. Sometimes Time Travel happened incidentally, like was described in the novels Crosscurrent and Riptide, and certain Force objects were known to open rifts in spacetime. Hyperspace travel did indeed cause the common "time dilation" effect (a mild form of time travel, if you can call it that at all), but ships used relativistic shielding to counteract this.

Cloaking technology existed, but not only blinded ships outside the cloaking field to the ship being hidden, but blinded the hidden ship's sensors and vision to the outside world, making it essentially blind. The use of cloaking devices was outlawed in the New Republic and Imperial Remnant soon after the Thrawn crisis.

Other things from Star Trek, such as Replicators did not exist in Star Wars, though Teleporters may have existed in some form during the reign of the Rakatan infinite empire. Other things, such as the technologies Richard mentioned in his answer, seem to be of low technological levels.

This answer is great. The first thing also came into my mind was Time Travel. – Evil Angel Feb 26 '14 at 2:19
@ssumner hmm, I'm not sure time travel was needed somewhere, but good point about the cloaking technology.. – Ray Feb 26 '14 at 4:26
But time travel does exist in some forms: – joshbirk Feb 26 '14 at 5:27
@joshbirk - yes, and I noted that. And even linked to the same page – The Fallen Feb 26 '14 at 13:50
Why the downvote? – The Fallen Feb 26 '14 at 13:51

I fear my answer might lead the question towards being a duplicate, but I can't find the original question I'm thinking of right now.

Technology in the Star Wars Universe is degrading generation after generation

Which is in of itself creating more and more limitations as the years go by. If you compare the technology of the Rakatan's Infinite Empire compared to what the Republic fights against at the end of Episode VI and even in the Expanded Universe ... they barely compare. The Death Star is considered a superweapon by the time of the New Republic, but it's really nothing compared to the Mass Shadow Generator or the Star Forge. Most of the truly powerful items in Star Wars are old if not ancient.

The relevancy here is that things which seem impossible in the Star Wars Universe currently is probably possible through some kind of ancient artifact or being. For instance, the now oft quoted lack of time travel was actually achieved in Star Wars via Splendid Ap who sent Leia Organa 8,000 years into the past. Splendid is a near omnipotent ancient being. Teleportation is possible, but only via Rakatan technology.

Counter to this, specifically when it comes to time travel, is Jacen Solo's use of flow walking - a form of time travel, but still modern ... just rare among Jedi.

So I would answer no - if it seems technologically impossible in Star Wars, it can be done either through a) ancient technology or artifact, b) some omnipotent being or c) The Force.
