Vibrating strings and string theory

Click For Summary

Discussion Overview

The discussion revolves around the concept of string theory, specifically focusing on the idea that particles are composed of vibrating strings. Participants explore the implications of this theory on the understanding of fundamental units in physics, including the relationships between humans, atoms, subatomic particles, and strings.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant asserts that string theory posits that all particles are made up of vibrating strings, suggesting that the vibrating string is the fundamental unit.
  • Another participant compares the relationship between nucleons and quarks to that of subatomic particles and strings, implying that subatomic particles are not fundamental but rather manifestations of strings.
  • A different viewpoint challenges the notion that concepts like nucleons or molecules cease to exist in light of string theory, arguing that each level of structure has its own relevance and should be studied independently.
  • A later reply confirms the basic idea that strings are the fundamental units, stating that the vibrations of strings correspond to properties like charge and mass.

Areas of Agreement / Disagreement

Participants express differing views on the implications of string theory for the existence of traditional particle concepts. While some agree on the fundamental role of strings, others argue for the continued relevance of established particle definitions.

Contextual Notes

There are unresolved assumptions regarding the definitions of particles and the implications of string theory on existing frameworks in physics. The discussion does not clarify how these concepts interact or the extent to which string theory replaces traditional particle physics.

The fundamental part of string theory is that particles are in fact made up of vibrating strings. So this means that the lowest form of unit is a vibrating string?

It goes like this

Human - made up of atoms - atoms made up of subatoms (electrons, protons and neutrons)- quarks. And then come the other smaller units until we finally arrive at a vibrating string. Am I right?

it's like how nucleons (protons etc) don't exist themselves, it's the up & down quarks that exist. in the same way the subatomic particles aren't themselves structures which are then composed of strings. instead the notion of a subatomic particle is replaced by that of a vibrating string.
sorry that was a long way of saying it.
make sense? :-]

To me it's not really wrong but awkward. You can not say a fruit salad is made of fruit so there is no salad. The concept of salad is relevant by itself. The concept of nucleon is relevant although it is true that nucleons are made up of quarks. The concept of molecule is relevant although it is made up of atom. I can continue for a long list :smile: At every scale there is an interesting structure which deserves its own study, and saying "it does not exist" must be taken with this grain of salt.

Yes. That is the basic idea.

The vibrations of the string manifest in the form of properties such as charge and mass.
