TL;DR: In this article, the authors argue that the case for "gravitizing" quantum theory is at least as strong as that for quantizing gravity, and that the principles of general relativity must influence, and actually change, the very formalism of quantum mechanics.
Abstract: This paper argues that the case for “gravitizing” quantum theory is at least as strong as that for quantizing gravity. Accordingly, the principles of general relativity must influence, and actually change, the very formalism of quantum mechanics. Most particularly, an “Einsteinian”, rather than a “Newtonian” treatment of the gravitational field should be adopted, in a quantum system, in order that the principle of equivalence be fully respected. This leads to an expectation that quantum superpositions of states involving a significant mass displacement should have a finite lifetime, in accordance with a proposal previously put forward by Diosi and the author.

Journal ArticleDOI
TL;DR: In Orch OR, consciousness is a particular manifestation of life’s quantum activity in these channels, involving ‘orchestrated’ quantum coherent superpositions that persist sufficiently to reach the physical threshold for ‘objective reduction’.

Journal ArticleDOI
TL;DR: The 2nd Law of thermodynamics was driven by the Big Bang being extraordinary special, with hugely suppressed gravitational degrees of freedom as mentioned in this paper, which cannot have been simply the result of a conventional quantum gravity.
Abstract: The 2nd Law of thermodynamics was driven by the Big Bang being extraordinary special, with hugely suppressed gravitational degrees of freedom. This cannot have been simply the result of a conventional quantum gravity. Conformal cyclic cosmology proposes a different picture, of a classical evolution from an aeon preceding our own. The ultimate Hawking evaporation of black holes is key to the 2nd Law and requires information loss, violating unitarity in a strongly gravitational context.

Journal ArticleDOI
TL;DR: The critical commentary by Reimers et al. as discussed by the authors is largely uninformed and basically incorrect, as they solely criticize non-existent features of Orch OR, and ignore (1) actual ORch OR features, (2) supportive evidence, and (3) previous answers to their objections.
