Blame this one on the apple that struck Newton’s forehead. After that incident (actual or fabricated) almost no one will ever doubt again the existence of gravity. Proving the realities of planets, stars, and galaxies; all that is needed is to gaze at firmament on cloudless nights or using powerful optical or radio telescopes. The accumulated evidences are beyond compelling short of touching by direct personal contact for an encounter of the 3rd kind.

However, living on a planet with perpetual cloud cover, who can say that gracons exist? Not even Newton’s apple exists, since plants and fruit trees needed starlights too. Then not even higher form of living things or lower form of cyanobacteria (blue green algae) that needed photosynthesis.

Without gracons, Einstein could never have formulated his general theory of relativity. If one perseveres along these relative roads to graconic reality, one will finally come face to face with the weakest but the biggest of all gracons, Infinity.
