Summary

Story summary

Rajendra Gupta, an astrophysics professor at University of Ottawa, proposes a CCC+TL model in which the constants of nature may vary over time to explain the universe without dark matter or dark energy.
Gupta argues that the universe's accelerated expansion could result from weakening forces rather than dark energy.
The study, published in The Astrophysical Journal, emphasizes the need for clear, testable predictions to validate or refute this alternative view.
