Can the 5brane turn into a fundamental string?
Ok, consider the following...fzero said:There are M-theory compactifications where the 5-brane can wrap 4 compact directions to give an object that is effectively a string in the limit where the size of the compact directions is very small. S-duality on these compactifications will switch the membrane and 5-brane so could lead to the identification of a wrapped 5-brane with the fundamental string in some dual theory.

In M theory, the elementary string that creates all particles is formed when an M2 brane is wrapped tightly around the circular dimensions. Now, when the M2 turns into a string, can the string that is open (with end points) attach its end points to an M5 brane? I have read in only few sources that they can
Yes, according to M theory, the 5 brane and 1 string are different configurations of the same fundamental object called a brane. This means that the 5 brane can be transformed into a 1 string and vice versa.
M theory is a theoretical framework that attempts to unify all five existing string theories into one theory. It proposes that there are 11 dimensions in the universe, with 10 of them being spatial dimensions and one being time.
In M theory, the 5 brane and 1 string are considered to be different manifestations of the same entity, known as a brane. A brane can have different dimensions, with the 5 brane being a 5-dimensional object and the 1 string being a 1-dimensional object.
Currently, there is no experimental evidence to support the existence of branes or the transformation between them. M theory is still a theoretical framework and is actively being studied and researched by scientists.
If the transformation between the 5 brane and 1 string is proven to be possible, it would provide further evidence for the concept of extra dimensions in our universe. It could also potentially lead to a better understanding of the fundamental forces and particles that make up our universe.
