Read "Physics of the Impossible" by Michio Kaku.

It's a great book that goes into detail regarding many of the subjects being discussed here.

Most of the advancements portrayed in these movies (Star Trek, Star Wars etc...) don't break the laws of Physics, and therefore aren't impossible to achieve.

However, as someone already pointed out, by the time humans can attain said technology and the energy required to produce it, we will be FAR removed from this planet.

Kaku discusses this in his book.

He does state that creating a "light" saber is impossible.

However, if I remember correctly, he notes an alternative would be to use a plasma beam in a sort of energy field to contain it.

Regardless, that form of energy does not exist in our Universe.


Hence, we cannot create a light saber either from said energy or actual light.
