So the masses of strings should be huge because of the high energy levels. Which means, in other words, the strings are vibrating with enough energy to have large masses as point particles. But quantum jitter offsets the high energy via negative energy, and makes the masses just right (what we observe).
How does this occur? Where does quantum jitter come from? What is negative energy? Is quantum jitter changing the vibration/resonance frequency of the string? If no, how is it acting upon the string?
