"Uh-oh. Y'all be talkin' smack about
Star Wars an' sh**. Dat sh** ain't goin' over."
Okay, whoever has the idea that Star Trek has the "potential to become science fact" is seriously misinformed. Some of the
ideas on Star Trek (in the old series, at least) such as wireless communicators and medical diagnostic beds, have come into being, but the science behind the show is a fictional as it gets.
Warp drive? No. Sorry. The entire basis of travel on the show breaks one of the fundemental facts of the universe, which is that light speed is as fast as it gets. Now everyone knows that - even at light speed - it's going to take a
really long time just to get to the nearest star, to say nothing of the nearest star with a planetary system, at least one of which supports intelligent and technologically sophisticated inhabitants.
So we need to "faster than light!" Guess what. You can't. So Star Trek Creator
invented the idea of a Warp Bubble, which would protect a ship from destruction (presumably from the wrath of a Universe which really
hates have its laws defied, or from an inverse time dilation, or something) as it magically slips into an imaginary cosmic jet-stream.
Now, there are some valid scientific theories that could "theoretically" get around the problem of being limited to light speed. One of these involves the idea that space is not uniform, but that it folds and twists, causing some places, which are far apart in our three-dimensional perspective, to actually be quite close together (relatively speaking) in another dimensional perspective. If one could somehow travel through that other kind of space, he could find himself traversing immense distances in a comparatively short time.
Some scientists call this strange space, "hyperspace." Sound familar?
So whatever reasons you have for picking one of these over the other, don't think of using scientific viability as one of them. (I mean, c'mon...
lightsabers?)
By the way, I totally dig Star Trek. Janeway's my mom.
Why even compare the two? Star Trek is science fiction, whereas
Star Wars is technological fantasy. It's like comparing peaches and nectarines.
