Nya supernovastudier ifrågasätter teorin om mörk energi

29 källor
  • Forskare i Oxford och Mumbai har reanalyserat över 1 700 supernovor och upptäckt att universums expansion ser ut att bromsa in snarare än att accelerera, när hänsyn tas till stjärnornas ålder.
  • Ett annat forskarlag lett från University of Queensland sammanställde 2 884 supernovor och fann tecken på att den mörka energin kan förändras över tid i stället för att vara konstant.
  • Andra kosmologer ifrågasätter slutsatserna. En konkurrerande studie i samma tidskriftsnummer hävdar att den kosmiska accelerationen fortfarande har starkt stöd i tillgängliga data.
