In string theory, the dS/CFT correspondence is a de Sitter space analogue of the AdS/CFT correspondence, proposed originally by Andrew Strominger.{{cite journal|last=Strominger|first=Andrew|date=2001-06-14|title=The dS/CFT correspondence|journal=Journal of High Energy Physics|volume=2001|issue=10|page=034|doi=10.1088/1126-6708/2001/10/034|arxiv=hep-th/0106113|bibcode=2001JHEP...10..034S|s2cid=17490361}} In this correspondence, the conjectured CFT boundary is in the future, and time is the emergent dimension.{{cite arXiv|last1=Anninos|first1=Dionysios|last2=Hartman|first2=Thomas|last3=Strominger|first3=Andrew|date=2011-08-29|title=Higher Spin Realization of the dS/CFT Correspondence|eprint=1108.5735|class=hep-th}}
