Title: Dark Energy Debunked? Cosmic Acceleration May Be an Illusion

Link: https://science.slashdot.org/story/26/09/10/0...

alternative_right shares a report from ScienceDaily: A new analysis of more
than 1,700 supernovae is questioning whether the universe is really
accelerating at all. After accounting for the ages of the stars that produce
these explosions, researchers found signs that cosmic expansion may actually
be slowing. They also argue that the apparent acceleration changes with
direction, which would be difficult to explain with dark energy. Other
cosmologists dispute the conclusion, setting up a major test for upcoming
observatories. The analysis has been published in Monthly Notices of the
Royal Astronomical Society. The conclusion is disputed, though. The report
mentions a separate paper co-authored by Professor Maria Vincenzi, also at
the University of Oxford, that "concludes that observations continue to
support an accelerating universe."
