Can a Jedi lightsaber cut through Superman?

I don't know. Superman is still made up of midi-chlorians (the force) which can be manipulated and moved.

that doesn't really relate to the question of whether or not a light saber could cut through him.

Darnit. Now I want to see a crossover of StarWars vs. Superman.

Darth Vader: “You will bow to the power of the dark side” *force chokes Supe”
Superman : *laser eyebeams Vader*

Or… Superman duel-wielding lightsabers. He would change his name so SuperAwesome Man

Question: Will a person asking this question ever have sex with a woman?

Answer: NO!

Sir, you are a nerd among men. Well played.

A lightsaber with a kryptonite focus crystal (the crystal that gives the lightsaber its shape and color) could probably cut through superman just fine.
Also the Sith do not use red lightsabers exclusively, it just so happens that most of the Sith in the movies had red lightsabers, which has to do with the focus crystal in question being one of the more common yet more powerful focus crystals. Read the books people!

- Yes, I am a geek, and proud of it.

Light sabers might be uneffective, but Superman's got some serious problems: http://www.youtube.com/watch?v=9wlZHmANoeA

I disagree…
It all comes down to the construction of the light saber.

If the primary crystal and focusing crystals were made out of Kryptonite the emmitted blade would easily cut through superman.

As each jedi must construct their own saber this is possible!!

Sorry

sorry Sage… did not read your comment before posting.
May the force be with you!

Wouldn't the jedi sword be powered by something?
what happens if the battery went out?

*sigh* Sabers use electromagnetic radiation, not plasma. v.v Though the reality is this question comes down to which Superman you are trying to cut, of course ignoring the specialized sabers.

Of course though I could entirely see a kryptonite crystal being used to focus the beam of a saber. xD

If the lightsaber had a krypton crystal inside then it would cut right through him.

“Hypothetically?” IT'S ALL HYPOTHETICAL.

Fantastic!

Ahhh, now I can sleep tonight….
