Summary

Story summary

The study suggests the universe could end in a Big Crunch in about 20 billion years.
Researchers, including physicist Henry Tye, propose dark energy may be changing, not constant.
This change implies a negative cosmological constant and a reversal of expansion around 11 billion years from now.
The model includes axions, hypothetical particles that could influence cosmic dynamics.
The scenario remains theoretical and needs data to confirm its validity.
