GURUTVA (गुरुत्व — heaviness, from guru, "the heavy") is gravity, named for the culture that first called it a force: the Indian astronomer Brahmagupta (c. 628 CE) — "it is the nature of the earth to attract." This domain traces the pull from Enheduanna's heavens to the graviton, and ties it to K·Q·V: gravity is the universe's attention — every mass attending to every other.
