Gravity Can Exist Without Mass and Dark Matter Could Be Myth, Says Study

According to Lieu, the gravity needed to hold some galaxies or clusters together might come from “shell-like topological defects.”
Topological defects are unique compact structures in space that have a high density of matter.
Such defects likely first occurred in the early universe during phase transition — an event during which matter throughout the universe goes through a major physical change.
This stuff makes my brain hurt, but I’m glad somebody is doing it.
