String Impermanence?

    Are the strings in M-Theory impermanent, do they decay for example?(I am not a physicist, curious from a philosophical perspective)

    How could strings decay if they are the fundamental unit of energy? What would they decay into? I would say string theory posits that strings are the bottom of the barrel.

    Thanks. So, they are not subject to quantum fluctuation?

    Thanks trimok. For some reason, when you mention the fracturing and melding of loops, the image I have is of the back side of a field. I'm starting to get the (mem)brane terminology. It seems impermanence applies only in the sense that the instance of a string form is constantly evolving. Still, I wonder if the loops themselves ever dissipate energy to the extent they pass out of existence. Perhaps branes pass out of interference in some way.
