The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

We review the question of whether the fundamental laws of nature limit our ability to probe
arbitrarily short distances. First, we examine what insights can be gained from thought …

According to a number of arguments in quantum gravity, both model-dependent and model-
independent, Heisenberg's uncertainty principle is modified when approaching the Planck …

The concept of minimum length, widely accepted as a low-energy effect of quantum gravity,
manifests itself in quantum mechanics through generalized uncertainty principles. Curved …

After many years, the deep nature of spacetime in string theory remains an enigma. In this
Letter we incorporate the concept of Born reciprocity in order to provide a new point of view …

We present an argument reinterpreting the generalized uncertainty principle (GUP) and its
associated minimal length as an effective variation of Planck constant (ħ), complementing …

The last three decades have witnessed the surge of quantum gravity phenomenology in the
ultraviolet regime as exemplified by the Planck-scale accuracy of time-delay measurements …

A bstract String theory is canonically accompanied with a space-time interpretation which
determines S-matrix-like observables, and connects to the standard physics at low energies …

In a natural extension of the relativity principle, we speculate that a quantum theory of gravity
involves two fundamental scales associated with both dynamical spacetime as well as …

Quantum theories of gravity predict interesting phenomenological features such as a
minimum measurable length and maximum momentum. We use the Generalized …
