Physical Coherence and Time's Emergence
Eugene Y. S. Chua
It is often said that time vanishes in quantum gravity. One general approach to quantum gravity accepts this fundamental timelessness but seeks to derive time's emergence at a non-…
De-Idealizing De-Idealization: Beyond Full Reversal
Yichen Luo, Eugene Y. S. Chua
There is a question of whether de-idealization is needed for justified use of -- for 'checking' -- idealizations. We argue that the standard philosophical account of de-idealizatio…
The Toll of the Tolman Effect: On the Status of Classical Temperature in General Relativity
Eugene Y. S. Chua, Craig Callender
The Tolman effect is well-known in relativistic cosmology but rarely discussed outside it. That is surprising because the effect -- that systems extended over a varying gravitation…
The Time in Thermal Time
Eugene Y. S. Chua
Preparing general relativity for quantization in the Hamiltonian approach leads to the `problem of time,' rendering the world fundamentally timeless. One proposed solution is the `…
