1982J. H. Schwarz in Physics Rep. LXXXIX. 227 The restricted DPM [= dual pion model]—which I refer to as ‘superstring theory’—is therefore the only candidate for a consistent theory of interacting strings free from ghosts and tachyons. 1984Phys. Lett. B. CXLIX. 122/1 The fact that anomaly-free type I superstring theories are chiral theories containing elementary gauge fields makes them appealing candidates for a fundamental theory. 1985Nature 3 Jan. 9/2 Superstrings are entities in ten dimensions (nine space-like, one time-like) which are expected to behave like ordinary particles when the ten dimensions are collapsed to four. 1988S. W. Hawking Brief Hist. Time xi. 172 Both theories lack observational evidence: no one has ever seen a giant tortoise with the earth on its back, but then, no one has seen a superstring either. |
