I am trying to find out if my general understanding of the strings in string theory is correct. The strings can vibrate along different nodes to create the particles. Do the strings themselves ever wander around as a whole string, or would they be considered to be locked in place like pieces of a grid? The way I picture it is that the strings, if they could be seen, would create a giant solid grid. A particle that is moving would jump from string to string as a vibrating wave, causing new strings to dance as it is seen to move, but those strings themselves are locked in the giant grid. All movement is not really movement, just vibration data being passed along the grid of strings. The grid of strings looks the same everywhere, even in a complete vacuum, but what would look different would just be the vibrations of the strings themselves creating matter and particles where it exists to the observer. Is this accurate, or are the strings themselves free to move around as well as vibrate?
