DESCRIPTION:Speakers: Ludovic van Waerbeke (UBC)\n\nThe discovery of cosmi
 c acceleration established dark energy as one ofthe central problems in co
 smology. In the standard cosmological model\,dark energy is described by a
  cosmological constant\, yet its extremelysmall value remains difficult to
  reconcile with expectations fromquantum field theory. Recent DESI results
 \, combined with othercosmological probes\, suggest that dark energy may e
 volve with cosmictime. In this talk\, I will first review the observationa
 l evidence fordark energy\, what current data tell us about its properties
 \, and whyevolving dark energy is theoretically challenging. I will then d
 iscussthe possibility that dark energy may not require a new particle orfi
 eld\, but could instead emerge from known but overlooked physics withinthe
  Standard Model of particle physics.\n\nhttps://conference.astro.dur.ac.uk
