Query: Schwarzschild-De Sitter black holes in 4+1 dimensional bulk   We construct a static solution for 4+1 dimensional bulk such that the 3+1
dimensional world has a linear warp factor and describes the
Schwarzschild-dS_{4} black hole. For m=0 this four dimensional universe and
Friedmann Robertson Walker universe are related with an explicit coordinate
transformation. We emphasize that for linear warp factors the effect of bulk on
the brane world shows up as the dS_{4} background which is favored by the big
bang cosmology.
