Building non commutative spacetimes at the Planck length for Friedmann flat cosmologies
Luca Tomassini, Stefano Viaggiu
We propose physically motivated spacetime uncertainty relations (STUR) for flat Friedmann-Lemaître cosmologies. We show that the physical features of these STUR crucially depend on…

Comment on "Can we measure structures to a precision better than the Planck length?"[arXiv:1205.3636], by Sabine Hossenfelder
Sergio Doplicher, Gherardo Piacitelli, Luca Tomassini +1
First principles do imply a non-zero minimal distance between events in spacetime, but no positive lower bound to the precision of the measurement of a single coordinate.

Physically motivated uncertainty relations at the Planck length for an emergent non commutative spacetime
Luca Tomassini, Stefano Viaggiu
We derive new space-time uncertainty relations (STUR) at the fundamental Planck length from quantum mechanics and general relativity (GR), both in flat and curved backgrounds…
