Phys. Rev. Lett. 63, 1203–1206 (1989)Defining the configuration space of string field theoryReceived 30 May 1989; published in the issue dated 18 September 1989 We propose a space for bosonic and heterotic string field theories in which all classical vacua are included naturally. WE also illustrate how space-time emerges. The existence of a new string symmetry beyond the usual Becchi-Rouet-Stora-Tyutin symmetry is pointed out. © 1989 The American Physical Society URL:
