Wormhole, is the picturesque name for a multiple connected region of space-time whose importance has been stressed byJ. A. Wheeler:Phys. Rev.,97, 511 (1955).
Several discussions with Dr.J. G. Fletcher have helped clarify the role of topology in quantized relativity, as well as the intrinsic difficulty in selecting an initial space-like surface.
