Modified cosmology through nonextensive horizon thermodynamics

Even in the case where the explicit cosmological constant is absent, the scenario at hand can very efficiently mimic \(\Lambda \hbox {CDM}\) cosmology, and is in excellent agreement with Supernovae ... geometry the apparent horizon becomes the Hubble one. The crucial point in the application of thermodynamics in cosmology is that the first law is interpreted in terms of energy flux and area of local
