...Scientists have believed dark energy was a "cosmological constant," but it is actually changing over time in unexpected ways...current data shows that, at the beginning of the universe, dark energy was very strong. But it has weakened with time and will continue to do so...The new research builds on data released from DESI in April 2024 that found signs that dark energy was changing. DESI has been surveying the universe for four years and an analysis of five years' worth of data is next for its research

This is essentially the kind of universe described by Eternal Inflation, one of the more popular theories of modern cosmology.
