Particles Aren’t Vibrations (at Least, Not the Ones You Think)

EXCERPT: You’ve probably heard this story before, likely from Brian Greene. In string theory, the fundamental particles of nature are actually short lengths of string. These strings can vibrate, and like a string on a violin, that vibration is arranged into harmonics. The more energy in the string, the more complex the vibration. In string theory, each of these vibrations corresponds to a different particle, explaining how the zoo of particles we observe can come out of a single type of fundamental string. It’s a nice story. It’s even partly true. But it gives a completely wrong idea of where the particles we’re used to come from....

EXCERPT: [...] The fact that particle species are types of vibrations isn't just a truth. It's pretty much "the defining truth", the very reason why string theory is unifying forces and matter. If you allow me to quote Barton Zwiebach's undergraduate textbook, "A First Course in String Theory":
Everyone who understands string theory agrees with the essence of the statement that string theory explains particles as vibrations....

Quote:Why is string theory a truly unified theory? The reason is simple and goes to the heart of the theory. In string theory, each particle is identified as a particular vibrational mode of an elementary microscopic string. A musical analogy is very apt. Just as a violin string can vibrate in different modes and each mode corresponds to a different sound, the modes of vibration of a fundamental string can be recognized as the different particles we know. One of the vibrational states of strings is the graviton, the quantum of the gravitational field. Since there is just one type of string, and all particles arise from string vibrations, all particles are naturally incorporated into a single theory. When we think in string theory of a decay process...
