A recent study conducted by Professor Kyu-Kyong Che from Sedzhong University in Seoul challenges the traditional theories of gravity proposed by Newton and Einstein. The study may indicate the existence of a new theory of gravity that differs from what is currently known.
Newton’s theory of gravity, proposed in 1687, successfully explained the interaction of bodies on Earth and in space. However, it failed to explain certain anomalies such as Mercury’s orbit. In 1915, Einstein introduced his “general theory of relativity,” which accounted for the interaction of mass and energy in space. Yet, even this theory could not explain phenomena occurring within black holes.
To address these gaps in understanding, scientists proposed the concept of dark matter. However, an alternative theory known as Modified Newtonian Dynamics (MOND), suggested in 1983, challenges this notion. MOND proposes that gravity behaves differently under very low accelerations.
During the study, Professor Che analyzed 26,500 wide double star systems using data collected by the GAIA space telescope. He discovered that under ultra-low accelerations, the observed accelerations were 30-40% higher than expected. This indicates a possible failure of the standard theory of gravity.
This unexpected increase in acceleration aligns with the Quadratic Lagrangian (AQUAL) theory of gravity under MOND. It provides direct evidence of the malfunction of standard gravity when dealing with weak accelerations.
In a press release, Professor Che explained that he chose to study these systems because “gravity can be most directly and effectively evaluated by calculating accelerations, as the gravitational field itself is acceleration.”
This study not only challenges established views but also paves the way for further research into the mysteries of gravity. The results of the study have been published in the journal “Astrophysics” and can be found here.
