Dark matter, dark energy might not exist: Study
A fresh study by physicist Rajendra Gupta suggests that dark matter and dark energy—thought to make up most of the universe—might not actually exist.
Instead, his model (called CCC+TL) explains cosmic expansion and galaxy rotation by saying that the universe's fundamental forces slowly weaken over time.
Gupta's model challenges existing theories
Gupta's theory combines older ideas like "Tired Light" with a new twist: a changing parameter called "a" tied to how much matter is around.
This single mechanism fits both the way galaxies spin and how light stretches across space, matching real data from classic galaxies just as well as standard dark matter theories.
A new perspective on cosmic age
Here's a wild part: Gupta's model says the universe is almost 26 billion years old—nearly twice what scientists thought before. That extra time could help explain how ancient galaxies and black holes formed so early.
Published in The Astrophysical Journal, this research challenges what we think we know about space and invites us to imagine new possibilities for how the cosmos works.
