New Insights from a Dark-Matter-Free Galaxy Revives Controversial Gravity Theory (Weekend Feature)

“In some sense, gravity does not exist,” observed physicist Michio Kaku of the weakest of the four fundamental forces of the Universe,”what moves the planets and the stars is the distortion of space and time.”


“Defying the Laws of Gravity” –Does a ‘Smoking Gun’ Nix Dark Matter Theory?

Dark Matter


In the early 1980’s Israeli physicist Mordehai Milgrom from Weizmann Institute proposed a new theory, “the smoking gun” –a new theory of the universe’s structure that offers the most plausible alternative yet to dark matter– that defied the laws of gravity suggesting that galaxies are governed by modified dynamics rather than obeying the laws of Newton and of general relativity. “This theory became known as MOND for modified Newtonian Dynamics, Milgromian Dynamics, or “modified gravity”–a viable explanation for a cosmological dilemma: that galaxies appear to defy the long-accepted rules of gravity traced to Sir Isaac Newton in the late 1600’s. In short, the mathematics of gravity may hint at weirder phenomena than many thought.
