Overview
- University of Ottawa physicist Rajendra Gupta proposes a covarying coupling constants model in which fundamental quantities such as light speed or gravitational strength change over time and location.
- He asserts the framework accounts for galaxy rotation, structure formation, gravitational lensing, and the appearance of accelerated expansion with a single equation, removing the need for dark components.
- Gupta’s study is published in the peer‑reviewed journal Galaxies and has been summarized by mainstream German outlets reporting his claims.
- A separate team from the University of Bremen’s ZARM and Transilvania University extends general relativity with Finsler geometry and finds that accelerated expansion can arise without adding a dark energy term.
- The ideas surface as dark matter and dark energy remain undetected, and ongoing surveys such as ESA’s Euclid are expected to provide data to test competing explanations.
