This paper presents a theoretical framework for primordial inflation driven by Tsallis holographic energy density, combining the holographic principle with non-extensive Tsallis entropy. The model predicts sufficient e-folds of inflation and is consistent with Planck 2018 constraints, offering a potential resolution to the cosmic coincidence problem.
Key findings
Proposes a new model of primordial inflation using Tsallis holographic energy density.
Predicts scalar spectral index and tensor-to-scalar ratio consistent with Planck 2018 data.
Connects inflationary epoch with dark energy domination, addressing the cosmic coincidence problem.
Limitations & open questions
The non-extensive parameter δ is constrained by observational data, which may limit model applicability.
Further research is needed to fully understand the model's implications for quantum gravity.
