While vibranium is incredibly strong and durable, it is unlikely to deflect a lightsaber effectively.
Here's why:
- Lightsabers are energy weapons: They generate concentrated plasma beams, which can cut through virtually any material.
- Vibranium is incredibly strong but not indestructible: It is known for its ability to absorb kinetic energy, but it is not impervious to extreme heat or energy.
- The energy output of a lightsaber is immense: The plasma blade generated by a lightsaber is extremely hot and powerful, capable of easily melting or vaporizing most materials.
While vibranium might be able to withstand a glancing blow from a lightsaber, it is unlikely to deflect the blade completely. The intense heat and energy of the plasma would likely melt or damage the vibranium, making it ineffective as a shield against a lightsaber.
