light-cone

Updated: May 18, 2025

Here in an external phenomenon we meet the same weakening in the light's tendency to expand that we recognized in the shortening of our experience of depth on looking through a dense medium. Obviously, we expect the externally observable narrowing of the light-cone and the subjectively experienced change of optical depth to show the same ratio.

These droplets would sometimes sparkle in a mild, unobtrusive way as they were nearing the light; and then they would dash against the pane and keep it dripping, dripping down. I leaned back again; and I watched the whole of the light-cone. Snow white wisps would float and whirl through it in graceful curves, stirred into motion by the horses' trot.
