    String Theory - From Physics to Metaphysics.Reiner Hedrich - unknown
    Currently, string theory represents the only advanced approach to a unification of all interactions, including gravity. In spite of the more than thirty years of its existence, the sequence of metamorphosis it ran through, and the ever more increasing number of involved physicists, until now, it did not make any empirically testable predictions. Because there are no empirical data incompatible with the quantum field theoretical standard model of elementary particle physics and with general relativity, the only motivations for string theory (...)

  2. The Internal and External Problems of String Theory: A Philosophical View. [REVIEW]Reiner Hedrich - 2007 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 38 (2):261 - 278.
    String theory is at the moment the only advanced approach to a unification of all interactions, including gravity. But, in spite of the more than 30 years of its existence, it does not make any empirically testable predictions, and it is completely unknown which physically interpretable principles could form the basis of string theory. At the moment, “string theory” is no theory at all, but rather a labyrinthic structure of mathematical procedures and intuitions. The only motivations for string theory consist (...)

    Quantum Gravity: Has Spacetime Quantum Properties?Reiner Hedrich - unknown
    The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - Quantum Mechanics gives a universally valid basis for the description of the dynamical behavior of all natural systems, then the gravitational field should have quantum properties, like all other fundamental interaction fields. And, if General Relativity can be seen as an adequate description of the classical aspects of gravity (...)

    Superstring Theory and Empirical Testability.Reiner Hedrich - unknown
    The quest for an all-encompassing theory, finally intended to give a solution to the problem of the unification of all natural forces, is seen today as one of the most important objectives of theoretical high-energy physics. This so-called 'Theory of Everything' is, actually, identified by some theoretical physicists with superstring theory. But superstring theory is in a crucial way incomplete. And, above all, it has fundamental problems with empirical testability – problems that make questionable its status as a physical theory (...)

    Quantum Gravity: Motivations and Alternatives.Reiner Hedrich - unknown
    The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity. It leads to the insight that, if gravity is a fundamental interaction and Quantum Mechanics is universally valid, the gravitational field will have to be quantized, not at least because of the inconsistency of semi-classical theories of gravity. The objective of a theory of Quantum Gravity would then be to (...)

    String Theory – Nomological Unification and the Epicycles of the Quantum Field Theory Paradigm.Reiner Hedrich - unknown
    String Theory is the result of the conjunction of three conceptually independent elements: the metaphysical idea of a nomological unity of the forces, the model-theoretical paradigm of Quantum Field Theory, and the conflict resulting from classical gravity in a quantum world - the motivational starting point of the search for a theory of Quantum Gravity. String Theory is sometimes assumed to solve this conflict: by means of an application of the model-theoretical apparatus of Quantum Field Theory, interpreting gravity as the (...)
