Abstract
We investigate propagations of graviton and additional scalar on four-dimensional anti de Sitter (AdS) space using gravity models with external sources. It is shown that there is the van Dam-Veltman-Zakharov (vDVZ) discontinuity in gravity models because gravity implies GR with additional scalar. This indicates a difference between general relativity and gravity clearly.
