From Mark Graham, University of Alabama
Thank you for the recent story on wormholes
(15 April, p 12).
Readers might be interested in the 1997 dissertation by Laszlo Forizs of Vanderbilt
University, “A New Class of Solutions to the Einstein Equations: Lorentzian
Wormholes with Rotating Throat”.
This shows it is possible to have a stable wormhole entirely without the
concept of exotic matter, and entirely consistent with the known laws of
physics.
