That reminds me. Arnold Schwarzanegger had a website for a while when he was running for Governator with an "Ask Arnold" section, into which he occasionally allowed kind of silly questions.

For example: "Who would win in a fight: A vampire or a werewolf?"

And also (here's the pertinent part): "Who would win in a fight: you or Yoda?"

I would have to agree: only a Kryptonite light saber would cut him. And why hasn't Lex Luthor thought of this one already?

Obligatory Stand by Me: "Who would win a fight, Mighty Mouse or Superman?" "Duh, Superman, cause Mighty Mouse is a cartoon but Superman is a real person!"

Question: if Midichlorians are part of everything, wouldn't that make them part of Superman, too? How would that influence a lightsaber? It seems to be able to cut through any material object, organic or not. I guess the question is, how does Superman actually get his imperviousness to damage? What is the mechanism. Much study, this requires.

Superman is impervious because Krypton has a much higher gravity and so they are more dense at the molecular level.

Goku v. Superman.
ftw.

@Gyrus: So politicians come from Krypton?

@NefariousNewt: What if there are no Midichlorians in the Milky Way Galaxy, and they are only found in a galaxy far, far away?

@NefariousNewt:

I think it would go something like the Venture Brothers episode where Number 21 tries to use a lightsaber on Brock.

"I've be gypped!"

@Seth L:

Go go gadget Youtube!

@Gyrus: No, that can't be right, because he loses his invulnerability when exposed to red sunlight for long periods of times. If he's just denser, where does the extra mass go?

Depends if we are talking Pre-Crisis Superman or Post-Crisis Superman. Pre-Crisis Superman could shrug off a strike from a lightsaber, since he demonstrated he could withstand plasma-like temperatures by flying into the sun. However, I do not believe that Post-Crisis Superman has ever endured plasma-like temperatures and therefore it is unknown if he could survive such. It is noteworthy that when Post-Crisis Superman faced Superboy-Prime (who had powers similar to Pre-Crisis Superman), the only way to defeat him was by pushing him into a red sun.

A light saber is to light as Superman is to normal matter. I think there is a good chance that a lightsaber might be a useful tool, say as Superman's nail-trimmers, or even as a razor. Or a way to remove super annoying earwax build-up.

I don't get Superman. If he has a neutron dense molecular structure (dense enough to withstand any baryonic or electro-magnetic attacks), then he would also have the gravity equivalent of a miniature black hole.

So, not only would a light saber do nothing at all, but the Jedi, the lightsaber, and everything around Superman would be sucked into his event horizon.

"Most people think that lightsabers that is powered up by Kryptonite could cut Superman." Sure, I'm sure that's what most people think about.

Oh, Kryptonite lightsabers. We love you, Internet.

@Strangeite: Isn't Post-Infinite Crisis Superman as powerful as Pre-Crisis On Infinite Earths Superman? Part of Kurt Busiek and Geoff Johns' "Up, Up and Away!" was that when Superman got his powers back, they were stronger than before and there were more of them, wasn't it?

@Gyrus: Nerd Alert!

Just kidding; I like the logic behind your answer, but I have to rule in favor of the lightsaber. It is technology from a Galaxy Far, Far Away, so it could rival Supes.

I thought he used one to shave.

A lightsaber won't work with any old crystal. The crystals all come from a single Jedi temple on a single planet. Kryptonite lightsaber is owt.

Also, the Superman invulnerability is probably the same sort of close-range telekinetic effect they invented to explain why giant objects hold together when supes picks them up.

the answer is: whatever fits the plot best of whoever writes a story that would include that fight for some god awful reason. The nonsensical 'scientific' rules you want to apply to it can be made up after. :P

A kryptonite lightsaber wouldn't be totally out of the question. Since in the New Jedi Order series, the characters made their lgihtsabers with different crystals and stuff.

So maybe a kryptonite lightsaber would work against Superman.

@VEN.BATISTA - Ding! Ding! Ding!!! We have a winner!

What the heck fun is a nearly-invincible super hero, anyway? Superman is totally lame.

@d00d34: Well, yah. But all the new Star Wars books are a retarded child's collage of "lightwhips", "lightdaggers", "lightnunchucks", and bizarre stupid things made out of animal teeth.

I try hard to forget lots of things about the Star Wars Universe. Seriously. The worst enemy Star Wars has is Star Wars. "Oh the force is bacteria". "Oh, there isn't actually a 'dark' side to the force, but it is ALL ONE". "Hey, I've got an idea! Let's clone EVERYBODY ALL THE TIME". "Oh, hey. The force affects everything. Just not these bug people. Oh but wait now it does". What a hokey load.

It's like comparing the original Dune books with the carnival of crap that Dune has become lately. Urgh. Makes me so sad. Why must decent mythologies be handed to people who ruin them?

A Jedi has a limit to how much he or she can move with the mind, and a Jedi cannot think or move fast enough to catch or outrun a being that can intercept a bullet, something a Jedi would be unable to protect him or herself from. Superman can take a bullet to the eye, the Jedi needs his lightsaber to stop a laser blast!

As for lightsabers, the answer is no!

@Graeme McMillan: I wish I could answer your question but marriage, a couple of kids and a mortgage payment has cut into my comic book purchasing power. I mostly keep up with the mythology now from friends. If you had asked me a comic book around 1993, I would have been your expert.

@Pope John Peeps II: It doesn't necessarily have to be powered by kryptonite, perhaps the handle was carved from a nice big chunk of kryptonite (since it only requires proximity to it to depower Supes). Now we're talking about a powerful, and stylish, lightsaber.

I say Yes, Superman could be stabbed by a powerful thrust of a lightsaber. He's not really invincible. It just appears that way to us puny Earthlings who haven't invented anything strong enough to hurt him.

But can it cut adamantium?

Well, Superman is vunerable to magic as well as Kryptonite, so a magic lightsaber could cut him. Hmm, I wonder if The Force could be considered magic.

@Jack: true dat.

@FrankenPC: Sounds like some twisted version of hamster in a tube porn >_>

@FrankenPC: DAMN YOU FOR MAKING ME PICTURE SUPERMAN'S EVENT HORIZON!!!

@Kaiser-Machead: Wouldn't a laser blast be traveling at the speed of light? I'd say the ability to deflect an incoming beam of light >>> ability to stop an incoming bullet any day.

That has nothing to do w/ Superman vs. lightsaber, I'm just sayin....

@ven.batista:

QFT

@Kaiser-Machead: But they can move fast enough to deflect a laser blast with a light saber, so they are technically moving at the speed of light, if not faster.

@Nately: Adamantium is weak sauce and has been cut through, melted, destroyed plenty of times.

I think since the midichlorians and the Force are mystical in nature, and Superman is vulnerable to magic, all bets are off.

And, now I need to go figure out where I last saw my life for having attempted to solve this riddle.

Jeebus, Graeme -- You're really trying to get Mike Sterling to laugh at us.

While we're at it, would you rather give Geordi back his eyes or make Data a human?

The real question is, if Yoda had the Soul Edge, could he cut Superman with that?

Didn't Superman shave by reflecting his heat vision back in a mirror or something?

@Kaiser-Machead:

Sounds like a list of awesome reasons for why Jedis are way cooler than Superman any day. ;)

@cde: No, the Jedi is fast, but not speed of light fast. He's merely so perfectly attuned to his surroundings that he can anticipate where the blaster bolt will land, and put the saber there.

@PiningForTheFnords: That's exactly how superman shaves. And trims his nails and hair.

@PiningForTheFnords: Atleast in the cartoon series, when Mr. Mixlzplick came visiting...

@Pope John Peeps II: But to be that attuned that you can deflect multiple s-o-l laser blasts that are supposed to hit different spots... You would need to move f-t-l after deflecting the first one to deflect the second one.

Lord Vader takes a swipe at Superman with his saber. Nothing happens. Frustrated, the Lord of the Sith tosses the weapon at Superman.

Superman winces.

@SUNDAYSUNDAY - I LOLed in a big way.

@rdcoyner: So Vader might not be able to use a lightsaber on Sup's, but he could force choke the bitch?

@Pope John Peeps II: But if his heat vision was hot enough to cut his super-durable hair, wouldn't it also melt the mirror?

@BRAAK - and that's why Superman sucks. I understand that in comics there has to be some suspension of disbelief (super powers in general are like that), but there are just a few too many inconsistencies with Supes that I can't get past.

I just wonder what would happen to the l.saber. Will it just hit his mass and stop short in length? Or will it stop the swing's inertia?

@cde: That's quite silly, considering the person aiming and firing the gun isn't moving as fast as light. The jedi would only have to move as fast as HIM.

Also, incidentally, blaster bolts are NOT lasers, and they do not travel as fast as light.

@braak: You would think so. But it DON'T. Heat vision can melt any and all substances, but it's just a laser, apparently. Nobody wants a hairy, silly Clark Kent. Also, this means that Superman spends whole weekends positioning mirrors in his apartment so that he can stare the hair off every part of his body.

"hey supes, what're you up to?"
"oh just some manscaping!" ZZZZPPPP.
