Dark energy survives major challenge as universe keeps accelerating
A bold claim that the universe’s accelerating expansion was an illusion has been put to the test-and failed. Researchers found that the study behind the controversy made key mistakes when analyzing supernova data. After revisiting the evidence, astronomers concluded that cosmic acceleration remains as strong as ever.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago.
