We study Bianchi cosmologies coupled to a matter source that has the field theoretical description of a solid. Models
of solid inflation are known for not being very efficient in diluting away anisotropy. While confirming this fact, our study finds another potential feature of Solid inflation, namely a ``rotation” of the principal axes of the expansion.
Such a rotation is not just a ...

Quantum gravitational effects are usually associated with the Planck scale but they could also become important at low energy if the wavefunction of the metric field fails to be peaked around a classical configuration.
I try to understand such deviations from classicality within canonical quantum gravity by introducing a "fluid of observers" in the low energy theory and defining a distance...
