### 1+1 dimensional slice of Schwarzschild-deSitter spacetime

Last change: June 12, 2002
The images depict a 1+1 dimensional slice of the
Schwarzschild-deSitter black hole spacetime, isometrically embedded
into 2+1 dimensional Minkowski space, which is identified with
Euclidean 3-space. Cross your eyes to see a stereogram. The four
regions of the Penrose diagram of the slice are each a different
color; the prominent ``X'' containing the origin (where the four
regions meet) is the horizon of the hole. In order to view the pair
properly, your browser window must be wide enough to show both frames,
but not so wide that it is difficult to cross your eyes far enough to
merge the images.
