Abstract
Entanglement islands play an essential role in the recent breakthrough in addressing the black hole information paradox. However, whether entanglement islands can exist in massless gravity theories is controversial. In this talk, we recover entanglement islands for massless gravity in wedge holography with DGP gravity on the brane. Furthermore, we discuss the possible resolutions to the island puzzle. Our works strongly support that the entanglement island is consistent with massless gravity theories.
