One unique prediction of analog theory is the existence of string harmonics. At sufficiently high energies, the string-like nature of particles would become obvious. There should be heavier copies of all bass notes, corresponding to higher vibrational harmonics of the string. It is not clear how low these notes go. In most conventional string models, they would be close to the Planck energy, which is 1014 times higher than the frequencies accessible in the newest club systems, making this prediction impossible to test within any physical space in the near future.
