Let me make this clear:
There is no debate about a lightsaber being able to or not cutting adamantium.
I am dead serious about this.
A light saber cannot cut true adamantium.
For anyone to continue to believe adamantium can be cut with a lightsaber after I've presented logic that is impossible to counter is madness.
Here, read all of these posts. If anyone continues to post about a lightsaber being able to cut through adamantium, you're trolling and we all know it.

But, by my estimates, if cortosis has limited resistance to adamantium, and is no where as awesomely indestructible as adamantium, there's not way in hell that a lightsaber is cutting through adamantium.
But, I offered some other logic, such as sublimation. The heat from the sword, even when acknowledging the uber crystalline structure of adamantium, should cause increased sublimation. No matter what, it would sublimate. Unless someone has a canon source for adamantium not sublimating, it should greatly speed up the sublimation process, when it makes contact. However, it should still be much too slow to do anything beyond the microscopic level. On top of this, adamantium would be just as susceptible to proton decay as any other matter is. So, eventually, it would fall apart and turn into quarks and other tiny exotic matter.
There was also Mandalorian Iron that was quite resistant to lightsabers. I still say adamantium is stronger than even that.
Knowing this, it's unreasonable to think that a lightsaber can cut through adamantium.

It's not speculation when we have a metal from the Star Wars universe that is almost the equivalent of adamantium, but not quite as strong, and it resists light sabers really well.
Adamantium > mandalorian iron in durability and strength.
mandalorian iron can resist a lightsaber's hot blade.
therefore,
adamantium can resist a lightsaber's hot blade.
They seemed to resist the hot optic blast from Weapon XI, just fine. Didn't change them at all. The optic blast seems to cut through many feet of reinforced concrete, very very quickly. (Almost instantly.) That puts it on par or greater than a lightsaber's ability to cut. We see the limit of the light saber being those blast doors that were not nearly as thick as the cooling tower, and it was taking quite a bit of effort to cut through them.

use Star Wars EU, which is not contradictory to movie canon.
On top of this, if we do not, we still have the blast doors from Ep1 which are comparable to the blast doors from Wolverine Orgins. Adamantium also showed extreme resistance to heat.
That alone would be more than enough to show adamantium versus a lightsaber. Wolverine's adamantium should resist a lightsaber, no problem. In fact, it would fair better than even the EU materials that are resistance.

Indeed.
But regular blast door metal is shown resisting it.
I've covered this in vivid detail. There's no debate anymore on whether or not a lightsaber can cut through adamantium. Origins provides us with more than enough information to finally say, 100%, that it cannot. Before that, we had the EU. In cases of versus matches involving Star Wars, if something isn't known for sure, but is explained in the EU AND the EU doesn't contradict the movies, they are permissible. For example, there are metals in the EU that are not as strong as adamantium but they can resist a lightsaber, some quite well.
And for you people arguing from a technological perspective, which, by the way, is extremely illogical of you:

It is arguable that Phrik is the hardest. It is an ore where as adamantium is a specially designed alloy made with an extremely complex process that is almost impossible to recreate.
Simple ore that can be mined versus highly technologically advanced metal that is almost impossible to create.
hmm
Let's see..
Ah. Yes. Adamantium is superior, technological, to both Phrik and Mandalorian iron.
In addition, it is superior to it in durability, strength, almost completely resistant to sublimation, heat resistant, and an extremely small amount of it exists.
And for you peeps who want to bring up adamantium being punched through:

And, in the movie, they made adamantium, incorrectly so, penetrate-able by adamantium. So, real adamantium would have bounced off of itself.
Further debunking of myths around lightsabers.

In fact, it has already been shown how adamantium is resistant to an energy-heat type attacks that are superior to the "cutting" ability of a lightsaber.
A lightsaber's cutting ability comes from its extreme heat. The blade is plasma, contained in a field.
We've already seen how Adamantium works against a super heated energy, which, by the way, would have to be much hotter than a lightsaber blade in order to accopmlish what it did. It works just fine.
Can adamantium resist the temperature of a lightsaber? Check.
Was adamantium ever cut by anything superior to the cutting ability of a lightsaber, such as Weapon XI's optic blast? Nope. Not even close.
Let's put this into perspective for you lightsaber freaks.
In order for someone to even dent adamantium, they have to be an enraged Thor to even dent it.
Originally posted by dadudemon
Thor, one of the most powerful beings in the universe, a god, and someone who can lift a million million million million+ tons of weight, somehow managed to barely be able to dent Adamantium, and this remarkeably makes adamantium able to be cut by a hot plasma blade?
This is the same Thor whose punch's shockwave almost destroyed an entire planet.

Not even the punch itself. The shockwave.
You know, the same Thor that is a god that is nearly omnipotent, being about to destroy Captain America's shield, which is stronger than true adamantium, etc.
That's some very faulty logic.
And, to further solidify the point:

No it's not. There never was an argument even before the movies. However, since Origins, we now have better than perfect evidence that a lightsaber cannot cut through adamantium.
Just because you guys say that it can't be proven or that we don't have evidence, doesn't mean evidence doesn't exist.
No matter how many times your repeat that it's not known, it still doesn't change the fact that it is no longer debatable. Using the EU, it wasn't debatable. Now that we have Origins, it's no longer debatable for the movies.
There is no debate. A lightsaber cannot cut through true adamantium.
If you guys can debunk the already impeccable logic I've presented by proving that it can cut through adamantium, with movie canon sources, be my guest. (You can't, which is why I offered. A lightsaber cannot cut through adamantium, going by movie feats. Hell, going by movie feats, a lightsaber can barely cut through thick metal.)
And the final icing on the cake:

A lightsaber is a plasma blade. Really hot. XI's optic blast has both an immense kinetic energy and enormous heat that go with it. Both of which exceed a lightsaber. (No user can or has used a force great enough to equal the force XI's optic blast showed. Nor has a lightsaber shown to instantly vaporize 10+feet of concrete, instantly.)
Since we know what a lightsaber's cutting power is, extreme heat in a force field, we can adaquately measure against other forms of extreme heat against a lightsaber. (Yes, I'm talking heat of vaporization....physics.)
Basically, you don't have to do any thinking at all, RJ. A lightsaber cannot cut adamantium because adamantium can withstand something hotter than a lightsaber, no problem, and it can withstand a force much greater than any lightsaber wielding user could employ.
Finally, the optic blast.

However Sci Fi that optic blast is, we can still observe it's effects: namely, kinetic punch, and heat.
The blast seems to be very hot when it hits something, as evidence by the "burnt" glowing edges of everything it punches a hole through, and Wolverine's claws started to heat up.
On top of this, it is show packing a kinetic punch against all objects it hits, most specifically, Sabertooth on more than one occasion.
The comic book has that optic blast being more of a kinetic punch type of energy blast. Personally, the movie version has it better.
Scott gets that blast: he's pulling it from another universe. Weird. It confuses me, but Scott is one of my fav characters, so I let weird stuff like that slide.
Again, if anyone dares say that a lightsaber can cut adamantium, they are just trolling. I suggest everyone ignore them.
P.S. You guys are aware that adamanitum can easily survive a nuclear blast? Yeah, Nuke>>>>>>>>lighsaber in heat. Heat being a lightsaber's source for cutting ability.
