Abstract
IT has been argued1 that even though a stable model of a white hole requires essentially zero delay between the big bang and the inception of expansion of the white hole, one can (at least in principle) still observe certain types of white hole, most likely those which never expand beyond their ‘Schwarzschild spheres’ into our space, and which have, in fact, always been visible. Here we report the main results of an analysis of the optical properties of such white holes, the complete details of which will be published elsewhere.
