Problems with String Theory in Quantum Gravity

String theory, a framework that aims to reconcile general relativity and quantum mechanics, holds a unique position in the field of quantum gravity. In quantum field theory, the main obstacle is the occurrence of the untreatable infinities in the interactions of the particles due to the possibility of arbitrary distances between the point particles. Strings, as extended objects, provide a better framework, which allows finite calculations. In the realm of theoretical physics, where theories often push the boundaries of human understanding, examining the epistemology of a theory becomes crucial. This article delves into the epistemological aspects of string theory’s role in our quest for a unified theory of quantum gravity, exploring the challenges it presents and the insights it offers.
