Beyond the Planck scale
Steven B. Giddings
I outline motivations for believing that important quantum gravity effects lie beyond the Planck scale at both higher energies and longer distances and times. These motivations ari…
Spontaneous Dimensional Reduction in Short-Distance Quantum Gravity?
Steven Carlip
Several lines of evidence suggest that quantum gravity at very short distances may behave effectively as a two-dimensional theory. I summarize these hints, and offer an additional…
Energy scale of the Big Bounce
Wlodzimierz Piechocki
We examine the nature of the cosmological big-bounce (BB) transition within the loop geometry underlying Loop Quantum Cosmology (LQC) at classical and quantum levels. Our canonical…
Husain-Kuchar model as a constrained BF theory
Merced Montesinos, Mercedes Velazquez
The Husain-Kuchar theory is a four-dimensional background-independent model that has long been viewed as a useful model for addressing several conceptual and technical problems app…
