Classicly

Unless the planet Earth were exploded, the ever-unstable Universe, itself, would collapse. Already the binding force was dangerously diminished. If new energy were not released within a month, disintegration would begin. The Universe would alter and flow and contract and after the collapse, slowly build itself into a new form—that form itself containing the inherent stresses of change and mutability. Only the arrival of starmen to space flight at the critical time—only their continued vigilance—prevented disaster beyond accounting for.
