For the first time ever, scientists find that gravity can exist without mass
Groundbreaking Research: A recent study by astrophysicist Richard Lieu suggests that gravity can exist without mass, challenging long-held beliefs in physics
Topological Defects: Lieu proposes that thin, shell-like structures known as "topological defects" may create gravitational forces without any detectable mass, potentially eliminating the need for dark matter
Mathematical Proof: This research presents the first mathematical proof indicating that gravitational effects can occur in regions where mass is absent, using a simplified version of Einstein's field equations
Implications for Dark Matter: If validated, this theory could significantly alter our understanding of galaxies and clusters, suggesting they do not require dark matter to explain their gravitational binding
Nature of Shells: The proposed shells consist of an inner layer of positive mass and an outer layer of negative mass, which cancel each other out to yield a net zero mass while still exerting gravitational force
Need for Further Research: While the findings are provocative, Lieu acknowledges that more research is needed to confirm or refute the existence of these topological defects and their role in gravity
A Paradigm Shift: This study could represent a paradigm shift in cosmology, prompting scientists to rethink fundamental concepts about gravity and the universe's structure
