Around galaxies, where the temperatures are cool, dark matter may be a superfluid, which has next to no viscosity courtesy of quantum effects. MOND calls for a revision of Newton’s law, and as extraordinary as this suggestion sounds, it does offer potential solutions to some otherwise troubling problems in galactic dynamics. New theory of general relativity casts doubt on dark matter ... without the need to assume the existence of dark matter. Slowly but surely, this tiny opposition to dark matter grew from just two physicists to several hundred proponents, or at least scientists who take MOND seriously. Verlinde’s theory will need to succeed at reproducing dark matter phenomena in cases where the old MOND failed. A Case of MOND Over Dark Matter According to Newton’s Second Law of Dynamics, objects on the farthest edges of galaxies should have lower velocities than objects near the center. Application of the MOND law has indeed had great success in fitting astronomical observations – without the need to assume the existence of dark matter. Intriguingly, MOND, despite it having only one free parameter, fits a large number of galaxies. MOND - an attempt by the "clueless", to extend Newtonian gravitation to the places it should not go. Kathryn Zurek, a dark matter theorist at Lawrence Berkeley National Laboratory, said Verlinde’s proposal at least demonstrates how something like MOND might be right after all. Historically, the answer has been it cannot, because of two factors: It … MOND's answers to the large-scale distribution of matter are about as wrong as saying 1 + 1 = 57.349. Also, dark matter began to explain other phenomena better than MOND even though MOND still … A new theory of gravity might explain the curious motions of stars in galaxies. MOND is a paradigm that contends to account for the mass discrepancies in the Universe without invoking `dark' components, such as `dark matter' and `dark energy'. By Adrian Cho Jan. 25, 2017 , 9:00 AM. MOND is an alternative explanation to the Dark Matter hypothesis that seeks to solve the galaxy rotation curve problem. We need something that acts like a dark matter-MOND hybrid. If dark matter is composed of weakly-interacting particles, an obvious question is whether it can form objects equivalent to planets, stars, or black holes. How would we know that the solar system isn't really run by an inverse-cube force law, but there is dark matter arranged just so as to make it look like an inverse-square law? Dark matter aggregation and dense dark matter objects. We analyse the rotation curves and gravitational stability of a sample of six bulgeless galaxies for which detailed images reveal no evidence for strong bars. MOND is an alternative explanation to the Dark Matter hypothesis that seeks to solve the galaxy rotation curve problem. The idea is following: one of the main astrophysical concepts after the emergence of Special and General Relativity and Quantum Mechanics is the idea of Dark Matter. WIMPs - no observational evidence to support them, at any energy level. We explore two scenarios: Newtonian dark matter models and MOdified Newtonian Dynamics (MOND). It does so by supplanting Newtonian dynamics and General Relativity, departing from them at very low accelerations. Abstract. Challenge from modified Newtonian dynamics rebutted. It is the idea of a mysterious… It does so by supplanting Newtonian dynamics and General Relativity, departing from them at very low accelerations.
