Sound Waves and String Theory.

Is the basic idea of string theory that all particles are tiny vibrating strings inspired from sonic boom?

A sonic boom is the sound associated with the shock waves created whenever an object traveling through the air travels faster than the speed of sound. Sonic booms generate significant amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.

So since sound is a vibration and the aircraft vibrates at sonic boom. Is this what inspired string theory? Since the aircraft can be viewed as a vibrating string of particles in string theory. So if the particles vibrate then they must be moving in the empty space within the object.

So since the aircraft is made up of strings these can vibrate at high velocity at sonic boom.

But one inference can be made here if we observe sound waves. 1. Sound is a vibration. 2. Sound waves require a medium. So if this is applied to string theory then:

1. All particles contain the vibration and contain an ultrasonic sound or so of a very high frequency.

2. The particles vibrate and require a medium. This medium could be the empty space between an electron and the nucleus.

Clarification.

Also it could be this way: The particles vibrate and produce sound but the space between the nucleus and the electrons is a vacuum and sound requires a medium to travel so we dont hear the sound. If the particles are strings.

I'm afraid it isn't. But you have a more or less decent example of what might happen Classically if we could model it on a string. But there are a couple of reasons why this inspiration wouldn't work well... Particles vibrating on a string are not vibrating in a medium, such as air. It kind of screws things up. Still you are talking about inspiration so that certainly isn't a fatal flaw.

As far as I know the inspiration is based on the idea that no theory, including Quantum Mechanics, can handle a point particle. We don't have to worry about this in String Theory as the particles have a finite, if incredibly small, size. The derivation of the string rules is very simple in concept (but Mathematically hideous from a Physics standpoint.) If there is any other reason for the inspiration I don't know of it.

I don't know this for certain, but
I had always assumed the original inspiration behind string theory would be musical.

One feature of vibrating strings is that they naturally feature fixed modes.
They will vibrate only in certain defined ways at certain defined frequencies.
This allows the possibility that the observed differences between quantum entities, could be related to the different vibrational modes available to these quantum strings.

I personally am beginning to feel that,
with the amount of time and effort that has been poured into this idea,
one might have expected a breakthrough by now,
if the breakthrough were there to find...

If you are referring to String Theory then there have been breakthroughs... In the theory. Very little can be tested at this point: it is making predictions we just don't have sensitive enough equipment for to do the actual experiments.

According to string theory, absolutely everything in the universe—all of the particles that make up matter and forces—is comprised of tiny vibrating fundamental strings. Moreover, every one of these strings is identical. The only difference between one string and another, whether it's a heavy particle that is part of an atom or a massless particle that carries light, is its resonant pattern, or how it vibrates.

The "inspiration" for string theory came about when it was noticed in the late 60's that phenomena associated with the strong nuclear force seemed to follow the mathematics of Euler's beta function, though at the time no one knew why that should be (i.e. they had a formula in search of a theory as to why it should work), and then in 1970 some physicists realized the physics of vibrating strings can also be described by the beta function. So voila - maybe the strong nuclear force (and by extension the other forces and fundamental particles) are actually incredibly small vibrating strings. And fundamental characteristics of particles such as mass, charge, and spin are manifestations of the resonances of the vibrating strings.

Is this another of those situations where a mathematical similarity leads to an analogy with macroscopic phenomena,
which can actually be deeply misleading and cause considerable confusion in the "lay" person.
Where any vague inkling of possible understanding based on the analogy,
is probably very wrong.
