Lorentz invariance and quantum gravity: an additional fine-tuning problem?

no code implementations • 12 Mar 2004 • John Collins, Alejandro Perez, Daniel Sudarsky, Luis Urrutia, Héctor Vucetich

Trying to combine standard quantum field theories with gravity leads to a breakdown of the usual structure of space-time at around the Planck length, 1. 6*10^{-35} m, with possible violations of Lorentz invariance.
