In mainstream astronomy, this phenomenon is explained by assuming that galaxies are surrounded by invisible dark matter that provides additional gravitational attraction.<\/p>\n<p>However, researchers have also continued trying to explain galactic dynamics by modifying the theory of gravity itself rather than invoking dark matter. In 1983, Mordehai Milgrom proposed that Newtonian gravity might need to be modified in regimes of very weak gravitational acceleration. In 2016, Verlinde proposed a new theory of gravity, known as \u201cemergent gravity,\u201d aimed at explaining gravitational phenomena on galactic scales without assuming the existence of dark matter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A researcher from Sejong University has used a new theory of gravity proposed by Erik Verlinde to predict the observed central surface density of dark matter.
