Mysteries Of Time

Genesis.

The opening paragraph of this novel states that time is more mysterious than a man, a woman, a world, ghosts or gods. See here.

Sf familiarizes us with the mysteries of:

time travel;
time dilation;
cosmic time spans.

For time spans, read Olaf Stapledon and later chapters of Genesis:

"Sol swung onward through its orbit, once around galactic center in almost two hundred million years..."
-PART ONE, IX, p. 96.

Time has another mystery, different timescales. When Christian Brannock looks at the heights of a Mercurian cliff, he reflects that:

"He might have imagined [the heights] were a storm front - on its own timescale the cosmos is neither enduring nor peaceful, it is appallingly violent -"
-PART ONE, III, 4, p. 23.

The cliff endures on a human, not a cosmic, timescale.
