Abstract
We propose a geometric restriction on Euclidean/Minkowski distance in
the embedding space being proportional to distance in the embedded spa
ce, to generate spacetimes with vanishing gravitational mass (R(ik)u(i
)u(k) = 0, u(i)u(i) = 1). They are in fact dual-flat. This is also the
condition that characterizes global monopoles and textures.
