Gaia Space Telescope Tests Predictions of Gravity
Recent studies have raised doubts about the accuracy of the long-standing theories on gravity proposed by Newton and Einstein. The theory of general relativity, which states that gravity is caused by distortions in space-time due to mass and energy, is being challenged by data from the Gaia Space Telescope, a mission conducted by the European Space Agency known as Gaia.
A discovery that defies the theory of relativity
Data collected at billion-pixel resolution by the European Space Agency’s Gaia space telescope has revealed a puzzling “anomaly” that challenges our fundamental understanding of the cosmos. This anomaly occurs when loosely bound stars exhibit motions that defy the standard model theories of gravity as proven by Albert Einstein and Isaac Newton.
According to a report by The Next Web, the astronomer who discovered this phenomenon is Kyu-Hyun Chae from Sejong University in South Korea. His study of binary star systems, where two stars orbit each other, revealed a deviation from Newton’s general law of gravitation and Einstein’s general theory of relativity, with accelerations remaining below 0.1 nanometers per second squared.
This discovery raises doubts about the validity of “dark matter”, which has often been used to explain such confusions. Chae pointed out the importance of testing gravity with wide binaries because dark matter does not affect these systems in their internal dynamics.
Professor Chae suggested that a concept known as Modified Newtonian Dynamics (MOND) could explain the reasons why established theoretical frameworks fail to explain the observed motions of these stars. MOND proposes to change the laws of gravity with small accelerations that correct the irregularities of the galactic rotation without the need for dark matter.
Professor Chae expects these findings to be further reviewed and refined as more information becomes available.
Chae emphasized the need for a major revision of cosmology. According to Chae, this discovery is a very exciting step in our journey to understand the cosmos. And maybe it can help us reveal various facts about the universe that are not yet known!
