Researchers have proposed a conceptual and geometric framework based on teleparallel gravity as an alternative starting point for future investigations into quantum gravity. This approach aims to address the limitations of Quantum Field Theory in Curved Spacetime (QFTCS), which, although successful, is a semi-classical framework with vacuum ambiguities and background dependence. QFTCS describes quantum matter on classical geometries but does not integrate gravity at the quantum level, a central challenge in modern physics.

The new framework distinguishes itself from other approaches to quantum gravity, such as Loop Quantum Gravity, string theory, and asymptotic safety, which face their own conceptual challenges. Teleparallel gravity, in contrast to General Relativity which describes gravity as spacetime curvature, encodes it in torsion. This is achieved by using coframe and spin-connection variables, allowing for a refined geometric description of gravitational degrees of freedom.

One of the key advantages of this teleparallel approach is that it naturally incorporates local Lorentz symmetry and fermionic couplings, while also exhibiting a gauge-like structure. Although the current work does not present a complete quantization of teleparallel gravity, its purpose is to identify the essential geometric and conceptual ingredients that such a formulation would require. This approach opens new avenues for exploring the quantum nature of gravity, offering a different perspective to existing paradigms.
