In this issue, George Musser covers the black hole information paradox — that information cannot be destroyed, and yet black holes appear to swallow it, leaving no trace when they evaporate. But new research confirms that black holes are reversible after all, conserving information. (see: the principle of reversibility - https://en.wikipedia.org/wiki/Time_reversibility).

Thus the cover concept: a black hole encased in an hourglass. When you turn to the interior spread, the black hole's reversibility is revealed: what goes in comes back out.
