Despite the fact that various names have been pinned to Metz, its seems that all of the above examples (including that of God) cannot even withstand the magnitude of Metz.
The reason this name continues to elude even the brightest of human minds is that the idea of Metz cannot possibly exist in a dimensional state. Metz is so powerful, it defies all laws of this or any other universe. Recent studies have shown that people who have attempted to comprehend this name have either disappeared, died spontaneously, or driven themselves into a pertinent state of insanity and/or catatonia. One common belief is that Metz is possibly the grounds on which everything and nothing is based. It seems to surpass the idea of infinity. Quantum physicists report that this Metz is Everything and Nothing. It or He is said to have unexplainable connections with the String and Superstring Theories as Metz resonates within every single layer of the multi-dimensional complex and yet still exists beyond that point which is where scientists have lost the trail. Various theologists and spiritual leaders believe that Metz is one who is, as they say, "The Answer". All attempts to understand this idea of Metz have failed.
