Abstract
Barrow proposed that quantum gravity effects might introduce fractal corrections to the area of the event horizon of black holes. The area law gets modified as , with . It was so far unclear whether this assumption could lead to meaningful quantum gravity theories beyond general relativity. In this paper, we argue that this is indeed the case. In particular, assuming Δ to be a radial function, we show that the Barrow hypothesis, together with Jacobson's approach can generate non-trivial modified gravity theories.
