The Twilight Zone, Season 1

Billy:
Why must that hour never toll?

Gaspar:
The lost hour must never come. If it strikes 12, eternal night falls, of which there is no recall. The light, the wind, the stars, this magnificent place we call the universe, it all ends. And in its place, waiting, always waiting, hungering to be fed, is darkness. No new beginnings, no world without end. Just the infinite emptiness.
