Can a Lightsaber cut through Adamantium?

The question of whether a lightsaber can cut through adamantium is a topic of debate and can be answered in different ways depending on the context and the specific universe or storyline being considered.

In the Main Marvel and Star Wars Universes

In the traditional Marvel Comics universe and the Star Wars universe, adamantium is generally depicted as nearly indestructible. Several sources indicate that a lightsaber would not be able to cut through adamantium:

• Adamantium has withstood plasma beams, Thor's hammer, and nuclear explosions, suggesting its durability is beyond what a lightsaber could overcome123.

In Specific Storylines or Alternate Universes

However, there are some exceptions and alternate scenarios:

• In a recent Marvel Comics storyline, specifically in the "Reckoning War" event, Marvel introduced a version of lightsabers that can cut through both vibranium and adamantium. This is a unique instance within the Marvel Universe and does not reflect the general properties of lightsabers or adamantium5.

Scientific Analysis

From a more analytical perspective, a video on the subject calculates the power output of a lightsaber and compares it to the properties of adamantium. It concludes that, given the high specific heat capacity and melting point of adamantium, a lightsaber would not have enough power to melt through it in a quick swipe, but prolonged contact could potentially allow the lightsaber to cut through3.

In summary, in the main universes of Marvel and Star Wars, a lightsaber is generally not capable of cutting through adamantium due to its extraordinary durability. However, specific storylines or alternate universes can introduce exceptions to this rule.
