“Symmetry as a Guiding Principle to Quantize Gravity”
Theorizing how gravity works at energies fifteen orders higher than experimentally tested seems to be an impossible task. Nevertheless, theorists have tried to quantize gravity but only by compromising with the long cherished symmetries of low energy gravity such as Lorentz and Diffeomorphism invariance. For example, Lorentz invariance is respected all the way to Planck scale both in String Theory and Loop Quantum Gravity but only the latter is Diffeomorphism invariant; Horava-Lifshitz gravity breaks Lorentz invariance and preserves only a restricted Diffeomorphism. In this light, I review these two symmetries in detail and discuss their implications.
