Default Hadronic Strings Reborn

Physicists gave up on hadronic string theory ~ 1973 because
1. It has tachyons (unstable false pre-inflation vacuum without ODLRO)
2. It has a massless spin 2 particle

But 1. means spontaneous broken vacuum symmetries that provide massless
Goldstone bosons that get eaten to make the Salam strong short range
hadronic graviton explaining the Regge trajectories universal slope ~
1/(1Gev)^2. String ~ Kerr blackhole G*^1/2 ~ 1 fermi.

In the case of spin 1 e.g. photon, one Goldstone boson needed to get 3
spin 1 polarizations.

So for spin 2 we need 3 Goldstone bosons (SU(2) chiral weak force) to
get the massive short-range hadronic graviton.
