SUMMARY

The discussion centers on the fundamental concept of string vibrations, positing that strings at the Planck length (approximately 10-33 cm) vibrate at specific resonant frequencies. It highlights that the graviton, a theoretical particle responsible for gravitational force, is modeled as a string with zero wave amplitude. The conversation also addresses the implications of string theory on the universe's size during a "big crunch," asserting that it cannot shrink below the size of a string. Additionally, the phenomenon of zero point energy is explained, emphasizing its role in preventing certain physical systems from reaching absolute zero temperature.

Why do strings vibrate??
 
Physics news on Phys.org
Here's nice explanation that is leading one to consider...?


The basic idea is that the fundamental constituents of reality are strings of the Planck length (about 10-33 cm) which vibrate at resonant frequencies. The http://www.wordiq.com/definition/Graviton (the proposed messenger particle of the gravitational force), for example, is predicted by the theory to be a string with wave amplitude zero. Another key insight provided by the theory is that no measurable differences can be detected between strings that wrap around dimensions smaller than themselves and those that move along larger dimensions (i.e., effects in a dimension of size R equal those whose size is 1/R). Singularities are avoided because the observed consequences of "big crunches" never reach zero size. In fact, should the universe begin a "big crunch" sort of process, string theory dictates that the universe could never be smaller than the size of a string, at which point it would actually begin expanding

This is a very significant physical result because it tells us that the energy of a system described by a harmonic oscillator potential cannot have zero energy. Physical systems such as atoms in a solid lattice or in polyatomic molecules in a gas cannot have zero energy even at absolute zero temperature. The energy of the ground vibrational state is often referred to as "zero point vibration". The zero point energy is sufficient to prevent liquid helium-4 from freezing at atmospheric pressure, no matter how low the temperature.

We had to look for a way in which to interpret the graviton from one to the many, and if we do this, do you not think we could have describe the nature of reality, from events who are releasing energy?

The http://www.cerncourier.com/objects/2000/cernexotic1_9-00.gif measure is a good example of the strings length and the distance measure. I'd have to be corrected here, but in this case it is not to hard to understand the field that is generated around this measure? If the nergy value changes according to the distance then what would have been revealled in the metric field. The energy increase in the distance would have found relevance to early supersymmetrical states, and definition in supergravity.

Fig. 1. In quantum chromodynamics, a confining flux tube forms between distant static charges. This leads to quark confinement - the potential energy between (in this case) a quark and an antiquark increases linearly with the distance between them.

Look for energy correlations between KK Tower and particle identifications in regards to those windings

How does the cylinder, become a boson(torus)?


I am open to correction.

Strings vibrate due to the physical properties of tension, density, and elasticity. When a string is plucked or strummed, it creates a disturbance in the air molecules around it, causing them to move in a wave-like pattern. This wave travels along the string, reflecting off the ends and creating a continuous vibration. The tension in the string determines the frequency of the vibration, while the density and elasticity of the string determine the amplitude and timbre of the sound produced. Therefore, the specific characteristics of a string, such as its length, thickness, and material, will affect the way it vibrates and produces sound. Additionally, external factors such as the force applied to the string, the angle of plucking, and the type of instrument also play a role in the vibration of strings. Overall, the vibration of strings is a complex phenomenon that is essential for creating music and understanding the physics of sound.
