👉 Incoexistence is a concept in physics and cosmology that refers to the state of being unable to exist or persist due to an external force. It's analogous to a planet not existing on its own, as it requires another celestial body (the Sun) to sustain life. The term can be used to describe situations where there is no clear path forward towards existence, such as when two planets are orbiting each other but never meet in any significant way due to the gravitational pull from their respective stars
