Has String Theory Been Disproven?
Introduction to String Theory
String theory has been a significant focus within theoretical physics for several decades. It aims to solve the problem of formulating a viable theory of quantum gravity and unifies the fundamental forces within one theoretical framework. In string theory, particles are considered as one-dimensional strings whose different vibrational patterns correspond to various particles1.
Criticisms and Lack of Empirical Evidence
One of the main criticisms of string theory is its lack of empirical confirmation. Critics argue that string theory has not produced specific predictions that can be tested experimentally, which is a fundamental requirement for a scientific theory1 2. This lack of empirical support has led some to view string theory as a case of science driven by sociological mechanisms rather than empirical evidence3.
Defense and Methodological Shifts
Despite the criticisms, some theorists defend string theory by suggesting that it represents a shift in scientific methodology. Richard Dawid, for instance, argues that string theory has contributed to a change in how scientific methods are viewed, advocating for non-empirical methods of theory assessment due to the current technological limitations in testing the theory directly1 3. This perspective suggests that the controversy over string theory is partly due to differing views on what constitutes good scientific practice1 4.
Paradigmatic Rift in Theory Assessment
The debate over string theory can also be seen as a paradigmatic rift between its proponents and critics. Proponents of string theory tend to have a high degree of trust in its viability, while many physicists in other fields are more skeptical. This rift is often attributed to different understandings of theory assessment, with some advocating for a broader conception of scientific methodology that includes non-empirical methods3 4.
Conclusion
In summary, string theory has not been disproven, but it remains highly controversial due to its lack of empirical evidence and the differing views on scientific methodology. The debate highlights a significant paradigmatic rift within the scientific community regarding the criteria for theory assessment and the role of non-empirical methods in scientific research.

The controversy over string theory stems from a failure to distinguish between epistemic justification and pursuit-worthiness, rather than a methodological revolution in science.
On the Conflicting Assessments of the Current Status of String Theory
The conflicting assessments of string theory's current status can be best understood as a paradigmatic rift between exponents and physicists in other fields, with exponents trusting its viability and others being more skeptical.
Relating non-relativistic string theories
Non-relativistic string theories, when viewed as isometry-preserving, are equivalent and can provide simpler quantum gravity models and useful limits for the AdS/CFT correspondence.
