[𝔦 • ──⃝─⃝⃝⃝⃝──] 'M' 이론 the M theory

“Perhaps our universe owes its existence to cosmic membranes touching each other as they flutter in a multiverse breeze.”

Thanks to the combination of string theory and supersymmetry, known as “superstring theory,” physicists developed at least five mathematical formulations in the late 20th century that seemed to demonstrate that general relativity and quantum mechanics were connected at the most elementary cosmological level.

All these formulations, which included ten dimensions of space and time, were related in complex ways, even though they seemed distinct from each other. Then, in 1995, a major conceptual breakthrough occurred: it was proposed that each of these superstring theories could be viewed as a limiting case of an even more complex theory involving an eleventh space-time dimension.

The mathematical idea of ​​membranes is crucial to this eleven-dimensional theory.

Just as a string is a flexible extension of a single point, let's imagine a two-dimensional membrane as a flexible extension of a string, like a flag that can flap in the wind along its width and height.

If we view the multidimensional universe as a structure in which particles and membranes can move and interact, exchanging varying amounts of energy between them, four-dimensional space-time structures, like our universe, can be created and destroyed and possibly coexist with other universes with different natural laws, boundaries, and durations.

The fusion of superstring theory and membranes makes possible the existence of multiple universes like ours, a four-dimensional cosmos that moves within an eleven-dimensional supersymmetric structure.

The capital letter in the name of this eleven-dimensional theory is intentionally ambiguous: it is the so-called "M-theory." Although its original hypothesis included the concept of membranes, subsequent theoretical calculations have suggested that they may not be necessary to describe its properties.

Its proponents have ironically suggested that, apart from the "M" in membrane, it could also mean "mystery" or even "magic."
