What is Koppa… ?
In the study of physical chemistry, the Greek letter gamma, ɣ, is typically used to represent surface tension. To avoid confusion with the Lorentz factor in theoretical physics, it was necessary to assign a new parameter for spacetime surface tension. The forgotten Greek letter Koppa, Ϙ, was chosen. Before being adopted and then omitted from the modern Greek alphabet, the Greek letter Koppa, Ϙ, had its origins in ancient Hebrew and Phoenician hieroglyphs. The ancestor Koppa glyph was drawn as the sun on the horizon and it signified light and the edge of time. Thus, Koppa seemed a fitting parameter to describe tension at the boundary of spacetime. In the Roman alphabet, Koppa corresponds to the letter Q.
