The vociferous debate between the dark matter community and the MOND (Modified Newtonian Dynamics or Modified Gravity) community continues. Like two sluggers in the middle of the ring delivering blows to each other in a boxing match, this fight has raged on for years. Now, in a breakthrough discovery that challenges the conventional understanding of cosmology, scientists at Case Western Reserve University have unearthed new evidence that could reshape our perception of dark matter. According to standard Newtonian gravity, stars on the outer edges of a galaxy should be slower due to diminished gravitational pull. This has never been observed, leading to the inference decades ago of an invented concept called dark matter, which has yet to be proven to exist. But even if it did exist, dark matter halos should come to an end at some point, so rotation curves should not remain flat indefinitely. This new analysis at Case Western Reserve defies this expectation, providing a startling revelation: The influence of what we call dark matter extends far beyond previous estimates, stretching at least a million light-years from the galactic center. Surprisingly, rotation curves of galaxies remain flat for millions of light years with no end in sight. Such a long range effect may indicate that the concept of dark matter—as we understand it—might not exist at all.
