Advanced technology is a staple in science fiction and Star Wars is no different (yes I know it is considered Science FANTSASY), but I can't help but feel that certain elements in sci-fi are inexplicably absent. Technology that should exist, but doesn't. Again, I know some of these techs would alter the storyline, but I'm looking at this purely from an in-universe perspective. In the Star Wars galaxy, their are scientists, and engineers, who strive to create better weapons, and better ways to get certain jobs done. The Death Star was a goal to revolutionize warfare. Surely the geniuses who designed it, may have had other ambitions. Here is a list of things I'm surprised have not been attempted to have been built in Star Wars.

1. Matter transmission- Where is the teleportation technology?

2. Time machine- Who wouldn't want to travel through time?

3.Matter replication- Uh? Instant food and supplies anyone?

4. Wormhole travel- Poof your their

5. Singularity weapons- Poof your dead.

6. Molecular phasing- Going through ships before destroying them from the inside.

7. Food in a pill- No more rations

8. Nanomorphic tech- Change into anything

All in all, why hasn't anyone tried to create this stuff. Is it perhaps too difficult for science to achieve and is deemed impossible. Is it currently being researched by top minds in a laboratory somewhere on Coruscant, or do these things pseudo-exist, and we just don't see them on screen as they are not relevant or pertinent to the story being told. What do you think? Have I missed any techs?
