Quantum Gravity: Meaning and Measurement
John Stachel, Kaća Bradonjić
A discussion of the meaning of a physical concept cannot be separated from discussion of the conditions for its ideal measurement. We assert that quantization is no more than the i…
Unimodular conformal and projective relativity
Kaća Bradonjić, John Stachel
We outline unimodular conformal and projective relativity (UCPR), an extension of unimodular relativity in which the conformal and projective structures play central roles. Under $…
Measurement of the space-time interval between two events using the retarded and advanced times of each event with respect to a time-like world-line
Giovanni Amelino-Camelia, John Stachel
Several recent studies have been devoted to investigating the limitations that ordinary quantum mechanics and/or quantum gravity might impose on the measurability of space-time obs…
Prolegomena to any future Quantum Gravity
John Stachel
I shall discuss some "conditions of possibility" of a quantum theory of gravity, stressing the need for solutions to some of fundamental problems confronting any attempt to apply s…
The Hole Argument for Covariant Theories
Mihaela Iftime, John Stachel
The hole argument was developed by Einstein in 1913 while he was searching for a relativistic theory of gravitation. Einstein used the language of coordinate systems and coordinate…
Structure, Individuality and Quantum Gravity
John Stachel
After reviewing various interpretations of structural realism, I adopt here a definition that allows both relations between things that are already individuated (which I call ``rel…
