A new study by astrophysicist Richard Lieu suggests that gravity can exist without mass, proposing thin, shell-like layers of 'topological defects' as an alternative to dark matter for explaining the gravitational binding of galaxies. Clare Watson reports via ScienceAlert: Lieu started out trying to find another solution to the Einstein field equations, which relate the curvature of space-time to the presence of matter within it. "The increasing frequency of sightings of ring and shell-like formation of galaxies in the Universe lends evidence to the type of source being proposed here," Lieu writes in his paper.
