The Triumph of Time is also known as A Clash of Cymbals.
In three years' time the two universes were doomed to inevitable,
catastrophic collision! When the scientists of the wandering planet,
journeying through inter-galactic space, heard the sound of hydrogen
atoms coming into existence out of nothing, they realized that they had
accidentally discovered the birthplace of continuous creation. They had
lifted the curtain and caught an instant's glimpse of the unknowable.
But to have looked it full in the face could have been no more
fatal. For later, much later, they were to learn that they had also
uncovered mankind's Day of Judgment!
