What Creates the Strings in String Theory?

Click For Summary

Discussion Overview

The discussion revolves around the nature of strings in string theory, specifically what causes or creates these vibrating one-dimensional strings. Participants explore the relationship between strings and electromagnetic radiation, as well as the broader implications of energy and information in this context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants inquire about the origins of the vibrating strings in string theory and whether they relate to electromagnetic radiation.
  • One participant suggests that M-Theory may provide insights, particularly regarding dualities among the five different string theories and their relation to the AsD/CFT world.
  • Another participant argues that while strings and electromagnetic waves share wave-like properties, they operate in different contexts, specifically noting that strings exist in Calabi-Yau space and are not simply at the lower end of the electromagnetic spectrum.
  • There is a discussion about the nature of energy, with one participant asserting that energy is a concept that can exist without specific units and relates to the differences between states.
  • Another participant challenges the notion that all energy is a form of electromagnetic radiation, suggesting that there are various forms of energy in the universe beyond EMR.
  • A question is raised about the distinction between energy and information, leading to a discussion on how information represents order in a system and its relationship to entropy and energy transfer.
  • One participant emphasizes that energy can be defined in various frameworks and may not conform to conventional units, especially in the context of string theory.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between strings and electromagnetic radiation, as well as the definitions and implications of energy and information. The discussion remains unresolved with multiple competing perspectives presented.

Contextual Notes

Participants highlight the complexity of defining energy and information, noting that conventional definitions may not apply within the framework of string theory. There are also references to the limitations of current understanding regarding the nature of strings and their vibrations.

Are there any theories as to what could possibly cause/create the vibrating one dimensional strings in string theory?

Are the strings at the lower end of electromagnetic radiation? Or something completely different?

What would answer that is M-Theory. Right now it's all about dualities where they may be facet of the same thing.. for example the 5 different string theories. M-Theory may be close to the AsD/CFT world in which superstrings as atyy mentioned are just emergence (or created) from what occurs in this boundary.
 
The vibration of the strings have in common with EM waves in the sense that they are both waves (and therefore can have similar mathematical equations).

However, the photon inherits the string and the string operates in calabi-yau space. Therefore, strings are not at the lower end of the EM spectrum... it's like comparing apples and oranges.

What causes the string to vibrate? Well that is what energy is. The universe exists by virtue of its energy just like the tics of a clock exist because the clock has been wound up.
 
Right but all energy we know of is some frequency of EMR? Right?

So the strings vibrating has to be some other kind of "energy"?
 
Energy is a concept. It implies a system with various states. Energy does not even require units "J" or "eV" as it can be unitless in some framework. It just relates to the difference between states and the action to go from one state to another.

EMR is an object operating in some framework. The word operating implies that there has to be some sort of energy. But EMR is hardly all the energy we know of since there are many other objects that operate in the universe (such as electrons, planets, animals, and stars).

Refrain from thinking that one object (such as EMR) is the basis of everything else. I prefer to think that nature forms an infinite regression whereby objects can be defined at any level.
 
What is a difference between energy and information ?
 
Information represents some kind of order in a system (like the arrangement of atoms, the modes of the strings in a subatomic particle, the position of planets, the mapping of a gravity field, words on a piece of paper)

In thermodynamics, the internal entropy of a system decreases as the system becomes more ordered and thus more information emerges. This means that the entropy outside of the system had to increase by AT LEAST that magnitude. This means that the net entropy always increases (at least as far as our universe is concerned as well as our current understanding of things).

Energy is the difference between two states. So for objects to become more (or less) ordered--increasing/decreasing information, energy has to be transferred. Remember: energy is the quantity of action and it is relative difference between two states.

Energy can be heat, kinetic energy of a moving mass, or even something without "kg" or "m" or "s" in its units. It is up to the investigator to decide what the units of energy are given some framework with objects and states. For example, in string theory, "kg" does not make sense in the units of energy because the notion of "mass" no longer applies. Conventional mass is a macroscopic property and is hidden from string theory. Energy needs to be redefined perhaps with units 1/s (frequency) or some other units.
