  This preliminary report proposes integrating the Maxwell equations in
Minkowski spacetime using coordinates where the spacelike surfaces are
hyperboloids asymptotic to null cones at spatial infinity. The space
coordinates are chosen so that Scri+ occurs at a finite coordinate and a smooth
extension beyond Scri+ is obtained. The question addressed is whether a Cauchy
evolution numerical integration program can be easily modified to compute this
evolution.
  In the spirit of the von Neumann and Richtmyer artificial viscosity which
thickens a shock by many orders of magnitude to facilitate numerical
simulation, I propose artificial cosmology to thicken null infinity Scri+ to
approximate it by a de Sitter cosmological horizon where, in conformally
compactified presentation, it provides a shell of purely outgoing null cones
where asymptotic waves can be read off as data on a spacelike pure outflow
outer boundary. This should be simpler than finding Scri+ as an isolated null
boundary or imposing outgoing wave conditions at a timelike boundary at finite
radius.
