New observations are forcing cosmologists to ask whether dark energy itself needs a rethink — and what replacing the standard model would actually cost.

Theory Briefing
- The standard cosmological model is under pressure from new observations that it struggles to explain, prompting debate among leading cosmologists.
- Dark energy — the mysterious force driving the universe's expansion — is a central target for revision if the model is to be updated.
- Physicists Ellis, de Rham, and Ekeberg debate whether the fix requires tweaking existing theory or scrapping foundational assumptions entirely.
- A new theory compatible with the observations may demand a fundamentally different account of how the universe is structured and evolves.
