Does anybody know if the same could be true of a gravitational "lens"? --JoSH" No reason why not; if the gravitational "lens" is producing more than one apparent object, *and if the path lengths/light travel time are the same*, the separated images would appear to flash together. This would only be true for a *very* specific set of positions, of course. Mark
