We have argued that quantum mechanics and general relativity give a lower bound δl l1/3l2/3P on the measurement uncertainty of any distance l much greater than the Planck length lP. Recently Baez and Olson have claimed that one can go below this bound by attaching the measuring device to a massive elastic rod. Here we refute their claim. We also reiterate (and invite our critics to ponder on) the intimate relationship and consistency between black-hole physics (including the holographic… Expand
Assessing the Montevideo Interpretation of Quantum Mechanics
This paper gives a philosophical assessment of the Montevideo interpretation of quantum theory, advocated by Gambini, Pullin and co-authors. This interpretation has the merit of linking its proposalExpand
Fundamental decoherence from quantum gravity: a pedagogical review
• Physics
• 2007
We present a discussion of the fundamental loss of unitarity that appears in quantum mechanics due to the use of a physical apparatus to measure time. This induces a decoherence effect that isExpand
Relational Physics with Real Rods and Clocks and the Measurement Problem of Quantum Mechanics
• Physics
• 2007
The use of real clocks and measuring rods in quantum mechanics implies a natural loss of unitarity in the description of the theory. We briefly review this point and then discuss the implications itExpand
Quantum clock: A critical discussion on spacetime
• Physics
• 2016
We critically discuss the measure of very short time intervals. By means of a Gedankenexperiment, we describe an ideal clock based on the occurrence of completely random events. Many previous thoughtExpand
Single-world consistent interpretation of quantum mechanics from fundamental time and length uncertainties
• Physics, Mathematics
• 2018
Within ordinary ---unitary--- quantum mechanics there exist global protocols that allow to verify that no definite event ---an outcome to which a probability can be associated--- occurs. Instead,Expand
Fundamental Loss of Quantum Coherence from Quantum Gravity
• Physics
• 2012
We discuss the fundamental loss of unitarity that appears in quantum mechanics when one uses physically realistic devices to measure time and space. The effect is independent of any interaction withExpand

Modern space-time and undecidability
• Physics
• 2008
The picture of space-time that Minkowski created in 1907 has been followed by two important developments in physics not contained in the original picture: general relativity and quantum mechanics. WeExpand
Salecker–Wigner–Karolyhazy Gedankenexperiment in light of the self-gravity
In Gedankenexperiment mentioned in the title, the imprecision in space-time measurement is related to the spreading of clock’s wave-function with the passage of time required for the measurement.Expand
Zeno meets modern science
No one has ever touched Zeno without refuting him''. We will not refute Zeno in this paper. Instead we review some unexpected encounters of Zeno with modern science. The paper begins with a briefExpand

On the detectability of quantum spacetime foam with gravitational-wave interferometers
• Physics

Abstract We discuss a recent provocative suggestion by Amelino-Camelia and others that classical spacetime may break down into “quantum foam” on distance scales many orders of magnitude larger thanExpand

Abstract A recent paper (gr-qc/9909017) criticizes our work on the structure of spacetime foam. Its authors argue that the quantum uncertainty limit for the position of the quantum clock in aExpand
LIMIT TO SPACE-TIME MEASUREMENT

Applying simultaneously the principles of quantum mechanics and general relativity we find an intrinsic limitation to quantum measurements of space-time distances. The intrinsic uncertainty of aExpand

Diosi and Lukacs in paper [1] claim to have shown that the uncertainty in space-time measurements derived by us [2] implies uncertainties of the Riemannian curvature. Here we show that their argumentExpand
