Tachyons are dominant in 26-D string theory. They were rejected by string theorists who then found a 10-D superstring theory that did not require tachyons. Since then (1984) similar superstring and supergravity theories have been found in 9, 10, 11 and perhaps 12 & 13 dimensions. I say perhaps because the 9, 10 & 11-D theories have all been shown to be more or less equivalent approximations to an underlying theory that has not yet been derived.
