The universe may end trillions of years sooner than we thought
New research suggests the universe may end in a 'Big Crunch' in about 33 billion years, much sooner than the trillions of years previously expected. This prediction is based on evidence that dark energy's influence changes over time, potentially reversing cosmic expansion. The study uses data from the Dark Energy Survey and a model combining axion fields with a cosmological constant. While compelling, the findings require further verification through additional observations.
- ▪The universe could end in a Big Crunch 33 billion years from now, according to a new cosmological model.
- ▪Recent data suggest dark energy's equation of state changes over time, challenging the idea of a constant expansion rate.
- ▪The axion dark energy model combines a dynamic axion field with a cosmological constant to explain observations.
- ▪Simulations based on this model predict a future reversal of cosmic expansion leading to universal collapse.
- ▪Current findings are promising but require more data to confirm the dynamic nature of dark energy.

Space Astronomy Cosmology The universe may end trillions of years sooner than we thought News By Paul Sutter published 28 April 2026 Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could end much sooner than we thought, new research suggests.

Astronomers use twinkling stars in galaxies like this one (NGC 5468) to confirm the universe’s expansion rate. But what if cosmic expansion were to slow down and reverse? New research looks at the implications on the lifespan of the universe. (Image credit: NASA, ESA, CSA, STScI, A.
