We consider a brane world residing in the interior region inside the horizon of the D3-brane. The horizon size can be interpreted as the compactification size in that the Planck scale $M_{pl}$ is determined by the ten-dimensional gravity scale $M_*$ and the horizon size $r_H$ via the relation $M_{pl}^2\sim M_*^8 r_H^6$, and the effective gravity on the brane world behaves in a world with six extra dimensions compactified with size $r_H$. The large mass hierarchy is simply translated into the large horizon size, which is provided by Ramon-Ramon charge of the D3-brane. This picture offers a possible mechanism of dilution of the cosmological constant via Hawking radiation
