The existence of a fundamental scale, a lower bound to any output of a position measurement, seems to be a model-independent feature of quantum gravity. In fact, different approaches to this theory lead to this result. The key ingredients for the appearance of this minimum length are quantum mechanics, special relativity and general relativity. As a consequence, classical notions such as causality or distance between events cannot be expected to be applicable at this scale. They must be… Expand
Dangerous implications of a minimum length in quantum gravity
The existence of a minimum length and a generalization of the Heisenberg uncertainty principle seem to be two fundamental ingredients required in any consistent theory of quantum gravity. In thisExpand
Probing deformed quantum commutators
Quantum gravity theories predict a minimal length at the order of magnitude of the Planck length, under which the concepts of space and time lose every physical meaning. In quantum mechanics, theExpand
Minimum length from quantum mechanics and classical general relativity.
It is shown that any primitive probe or target used in an experiment must be larger than the Planck length lP, which suggests a Planck-size minimum ball of uncertainty in any measurement. Expand
On the precision of a length measurement
We show that quantum mechanics and general relativity imply the existence of a minimal length. To be more precise, we show that no operational device subject to quantum mechanics, general relativityExpand
A Note on Coherent States with Quantum Gravity Effects
Abstract Existence of a minimal measurable length and an upper bound for the momentum fluctuations are the casting reasons for generalization of uncertainty principle and then reformulation ofExpand
A possible thermodynamic origin of the spacetime minimum length
In this paper, by applying the generalized uncertainty principle (GUP) at the final stage of black hole evaporation, we have proposed a thermodynamic explanation for the minimal scale of quantumExpand
Structural issues in quantum gravity
A discursive, non-technical, analysis is made of some of the basic issues that arise in almost any approach to quantum gravity, and of how these issues stand in relation to recent developments in theExpand
Dimension and Dimensional Reduction in Quantum Gravity
If gravity is asymptotically safe, operators will exhibit anomalous scaling at the ultraviolet fixed point in a way that makes the theory effectively two-dimensional. A number of independent lines ofExpand
Scale Dependent Metric and Minimal Length in QEG
The possibility of a minimal physical length in quantum gravity is discussed within the asymptotic safety approach. Using a specific mathematical model for length measurements ('COM microscope'), itExpand
Quantum Gravity: a Progress Report
The problem of reconciling general relativity and quantum theory has fascinated and bedeviled physicists for more than 70?years. Despite recent progress in string theory and loop quantum gravity, aExpand


A generalized uncertainty principle in quantum gravity
We discuss a Gedanken experiment for the measurement of the area of the apparent horizon of a black hole in quantum gravity. Using rather general and model-independent considerations we find aExpand
Planck length as the lower bound to all physical length scales
The effect of quantum fluctuations of gravity on the measurement of proper distances is considered. It is shown that, when the length scales are of the order of Planck length, the concept of a uniqueExpand
Physical significance of planck length
The significance of Planck length in a quantum gravity model is investigated by concentrating on the conformal degree of freedom. It is shown that Planck length is a lower bound to physical properExpand
On the Quantum Structure of a Black Hole
The assumption is made that black holes should be subject to the same rules of quantum mechanics as ordinary elementary particles or composite systems. Although a complete theory for reconciling thisExpand
Limitations on the operational definition of spacetime events and quantum gravity
Using simple arguments from general relativity and quantum theory the author shows that it is not possible to devise experiments (or operational procedures) which will measure the position of aExpand
Weaving a classical metric with quantum threads.
It is shown that there exist quantum states which approximate a given metric at large scales, but such states exhibit a discrete structure at the Planck scale. Expand
The role of general relativity in the uncertainty principle
The role played by general relativity in quantum mechanics (especially as regards the uncertainty principle) is investigated. It is confirmed that the validity of time-energy uncertainty does dependExpand
A Generally covariant quantum field theory and a prediction on quantum measurements of geometry
We define a generally covariant quantum field theory with an infinite number of degrees of freedom. This is obtained by combining the Husain-Kuchař model, the Loop Representation, the idea ofExpand
On the interpretation of minimal length in string theories
The existence of a minimal observable length in fundamental string theories has been suggested from recent investigations of the string amplitudes under various extreme conditions. SeveralExpand
Quantum gravity and string theory: What have we learned?
This is a non-technical talk given at the Sixth Marcel Grossman Meeting on General Relativity, Kyoto, Japan in June 1991. Some developments in string theory over the last six years are discussedExpand
