New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

To match observation, the dark matter EOS must oscillate in time. ... Evolving Dark Energy or Evolving Dark Matter?, arXiv (2025). DOI: 10.48550/arxiv.2505.02645. Provided by Universe Today.

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy.

MIT physicists propose that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early ...

Dark energy explains the observation that the universe’s expansion rate is accelerating. But its origins are unknown. It’s typically expected to have constant density across the billions of ...
