New Cosmic Glitch Model Offers Clues to Unraveling Gravity Puzzle at Universe’s Edge
A recent study has proposed a new model that may explain the cosmic glitch at the edge of the expanding universe, where gravity weakens by about one percent. This new model, developed by Robin Wen and Niayesh Afshordi, modifies and extends Einstein’s widely accepted theory of general relativity without compromising its validity.
The widely accepted model of gravity, based on Einstein’s theory of general relativity, has been tested and confirmed through various experiments. While this theory has been crucial for understanding concepts like the Big Bang and black holes, scientists have encountered discrepancies in its predictions when applied to the cosmic scale.
Astronomers have known for over a century that the universe is expanding, with some proposing that this expansion could be attributed to a weakening of gravity at the edge. This observation led researchers to explore the idea that Einstein’s theory may not fully explain gravity on extremely large distances.
Wen and Afshordi believe that this new model could be the starting point for solving a broader cosmic puzzle spanning across space and time. By acknowledging that certain adjustments are necessary when studying phenomena at a cosmic scale, scientists hope to gain a deeper understanding of the universe’s structure and evolution.
