Spaces of embeddings can be studied using the homotopy-theoretic approach of Goodwillie and Weiss. When applied to the space of knots this method produces a sequence of knot invariants which are conjectured to be universal Vassiliev invariants. This is remarkable since such invariants have been constructed only rationally so far and many questions about possible torsion remain open. In this talk I will present a proof that these invariants are surjective maps, which confirms part of the conjecture.
