- Are astronomers wrong about dark energy? New study casts . . .
Are astronomers wrong about dark energy? New study casts doubt on universe’s accelerating expansionExtraordinary claims The new research proposes a radical revision of accepted knowledge, so
- Are Astronomers Wrong About Dark Energy? - Slashdot
An anonymous reader shared this report from CNN: The universe's expansion might not be accelerating but slowing down, a new study suggests If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our understanding of dark energy, the elusive force that coun
- What’s Driving Dark Energy? New DESI Data Suggests Evolution
Recent DESI observations suggest what’s driving the dark energy involves dynamic evolution rather than static cosmological constant Understanding what’s driving dark energy requires examining quantum vacuum energy, quintessence theories, and potential dark sector connections
- Is Einstein’s “Cosmological Constant” Wrong? New Data . . .
Shajib: In these models, the dark energy density decreases with time Dark energy is the reason for the universe’s accelerated expansion, so if its density decreases, the acceleration will also decrease with time If we consider the very far future of the universe, different characteristics of dark energy can lead to different outcomes
- Have We Been Wrong About Dark Energy All Along? New Study . . .
The cosmic microwave background radiation, distant supernovae, and the large-scale structure of galaxies have all been studied under the assumption that dark energy exists If acceleration arises instead from geometry, those models may need to be reexamined Moreover, the discovery could reshape the way we think about the fate of the universe
- Dark Energy Is Weakening—and We Might Be Wrong About How the . . .
The Dark Energy Spectroscopic Instrument (DESI) collaboration just dropped their first official data release, covering the first 13 months of the instrument’s operation While many conclusions
- Why ‘Evolving’ Dark Energy Worries Some Physicists . . .
If dark energy is weakening, as suggested by recent results, then the cosmos is far stranger than most physicists had supposed
