"Revealing Modified Gravity: Wide Binary Stars and the MOND Debate"

A new study published in The Astrophysical Journal provides further evidence for modified gravity at low acceleration, reinforcing previous findings from 2023. The study, conducted by Kyu-Hyun Chae of Sejong University, analyzed wide binary stars observed by the Gaia space telescope and revealed that these systems experience larger accelerations than predicted by Newtonian physics at low gravitational forces. This anomaly aligns with predictions from modified gravity theories such as MOND, suggesting a potential paradigm shift in our understanding of gravity and its implications for astrophysics and cosmology.

New Study Challenges Newton's Law of Gravitation and General Relativity with Gaia Observations

A new study by Sejong University physics and astronomy professor Kyu-Hyun Chae has found evidence for the breakdown of standard gravity in the low acceleration limit, challenging Newton's Law of Gravitation and General Relativity. Chae analyzed the dynamics of wide binary stars using data from the Gaia space observatory and found that low accelerations exhibited behavior inconsistent with current theories. This supports the controversial theory of modified Newtonian dynamics (MOND) proposed by Mordehai Milgrom four decades ago. Chae's findings suggest the need for a new theory that extends general relativity to account for the low acceleration MOND limit and could have profound implications for astrophysics and cosmology.

"Gaia Observations Reveal Smoking-Gun Evidence of Modified Gravity in Low Acceleration"

A new study using data from the Gaia space telescope provides conclusive evidence for the breakdown of standard gravity in the low acceleration limit. By analyzing the orbital motions of wide binary stars, the study finds that accelerations lower than about one nanometer per second squared deviate from the predictions of Newton's universal law of gravitation and Einstein's general relativity. This breakdown of standard gravity at low accelerations aligns with the predictions of modified Newtonian dynamics (MOND) and suggests the need for a new theory to explain phenomena in the weak acceleration limit. The findings have significant implications for astrophysics, cosmology, and fundamental physics.
