Shine a flashlight or burn a candle and the photons go at the speed of light through empty space til they hit something. The light of a candle in a featureless desert proceeds in space to the limits of being. That light is absorbed by something or moves on forever. Brain waves are no less an element of electromagnetic emanation. The sphere of your existence is written into the fabric of being at the speed of light times your age.
Let those who have eyes see.
The earthworm and the elephant.
