- Emergent Gravity seeks to replace the need for dark matter. According to the theory, gravity is not a fundamental force that "just is," but rather a phenomenon that springs from the entanglement of quantum bodies, similar to the way temperature is derived from the motions of individual particles. http://www.astronomy.com/news/2018/05/the-case-against-dark-matter 558 comments space
