Study of 2,884 supernovae suggests dark energy may change over time
ScienceDaily reports that a University of Queensland-led team unified 2,884 supernova observations and says dark energy may vary over time.
The short version
- ScienceDaily reports that a University of Queensland-led international team brought together observations of 2,884 Type Ia supernovae.[ScienceDaily]
- The team says combining the data with Big Bang relic light and galaxy distribution maps points to dark energy changing over time.[ScienceDaily]
- Professor Tamara Davis says the new compilation deviates from the standard model, though in a slightly different direction than earlier DES data.[ScienceDaily]
Key facts
- The study brought together observations of 2,884 Type Ia supernovae from an international team led by University of Queensland scientists.[ScienceDaily]
- Researchers combined the supernova data with relic light from the Big Bang and maps of galaxy distribution.[ScienceDaily]
- The team says the results provide more evidence that dark energy may change over time rather than remain fixed.[ScienceDaily]
- Professor Tamara Davis said 2024 supernova data from the Dark Energy Survey first hinted at time-varying dark energy.[ScienceDaily]
- Davis said DESI surveys of relic sound waves also found hints of dark energy variations.[ScienceDaily]
What remains uncertain
- The time-varying dark energy interpretation is the team's own conclusion and is not independently confirmed in the reporting provided.[ScienceDaily]
- The reporting provided does not describe next steps or any independent review of the analysis.[ScienceDaily]
- Only ScienceDaily reports this event, so the findings rest on a single outlet's account.[ScienceDaily]
