Uncovering the Predictive Power of String Theory

Click For Summary

Discussion Overview

The discussion revolves around the predictive power of string theory and its potential applications in explaining established scientific phenomena, such as planetary motion and other physical effects. Participants explore whether string theory should provide valid predictions for areas already covered by existing theories.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the validity of string theory's predictions, asking if it can explain phenomena like planetary motion or weather.
  • Another participant argues that string theorists focus on problems where existing theories fail to provide valid predictions, implying that string theory's goals differ from those of classical physics.
  • A participant suggests that if string theory is correct, it should also provide reasonable explanations for established scientific principles, indicating a desire for coherence with known physics.
  • It is noted that string theorists aim to demonstrate how string theory can reduce to general relativity (GR) and quantum field theory (QFT) under certain conditions, rather than reworking established physics.
  • One participant expresses skepticism about the acceptance of string theory due to its departure from established quantum physics, suggesting that it may be challenging to change existing beliefs among physicists.
  • Another participant asserts that if string theory is valid, it should encompass explanations across various scientific disciplines, including physics, astrology, cosmology, biology, and chemistry.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the expectations of string theory's predictive capabilities and its relationship with established scientific theories. There is no consensus on whether string theory should provide predictions for phenomena already explained by classical physics.

Contextual Notes

Participants express differing views on the goals of string theory and its implications for existing scientific knowledge, highlighting a lack of clarity on how string theory relates to established theories.

Does string theory give any valid predictions? For example could string theory dictate the motion of the planets, or the weather, or gravitatoinal effects or just really anything that is useful. All I ever hear about it string theory showing bizarre things like time in black holes and what not. What are scientists not trying to make valid predictions?

Thanks...

But we already know how to predict the motion of the planets, don't we? String theorists work on the problems that they do because those are precisely the problems for which existing theories don't give valid predictions.
 
Well I mean if string theory is absolutly correct should it not give reasonable explanations for science that is already considered correct? Should that not be a goal too?
 
It is a goal, but that is not to say that string theorists are interested in re-working out all of the minutiae of known physics, nor should they be. They are interested in showing how string theory reduces to GR, QFT, etc..., under the appropriate conditions.
 
If you are interested, read the string theory (part one two and three) intro that i wrote for my journal. Make sure you scrool down to part one first which is on the bottom of the page...enjoy and feel free to ask more questions

Well if you consider the aspects of string theory there is a whole lot to change if such a theory exsists. Quantum physics explains how smaller particles "work and function" relative to their environment while saying that everything is made up of strings ( i know its more detailed then that ) is really bizzare. Since quantum physics was before the string theory it is hard to change what a lot of Physicists think. So to get to your point I agree that string theorists should use more of their time actualy explaining how everything works.
 
I also would like to say that if the theory is right then if should explain a lot of scientific topics such as every specific type of physics, astrology, cosmology,and biology and chemistry.
