After mysterious “Ascensions” cause people to rise into the sky when they lose their sense of identity and purpose, physicist Elias Vance and psychologist Anya Rao discover that the phenomenon is tied to a measurable force they call Identity Density. As governments and media struggle to control the narrative, Elias and Anya realize that collective belief and emotional disconnection strengthen the pull, while storytelling, community, and human bonds literally anchor people to Earth. In the end, humanity survives not by defeating the cosmic force, but by choosing connection over emptiness, proving that meaning itself is a form of gravity.
