Thurston showed the existence of a six component link in the 3-sphere such that every three-manifold can be expressed as a branched cover of the 3-sphere branched over this link. He called links with this property "universal links'' and asked if a universal knot exists. The authors confirm this by showing that any link can be embedded in the branch locus of a 3-sphere branched covering of a 3-sphere branched over a knotengjournal articlehttp://www.ams.org/journals/bull/1983-08-03/S0273-0979-1983-15114-5/S0273-0979-1983-15114-5.pdfhttp://www.ams.org/home/pagerestricted access515.162.83-manifolds as branched covering spaces over 3-sphereuniversal knotTopología1210 Topología
