“…Lajos Diósi compares two fundamental concepts of irreversibility which, as he emphasizes in this work, have “emerged and evolved with few or even no interactions” [ 19 ]. First, the concept of universal gravity-related irreversibility, and, second, irreversibility in “quantum state reductions, unrelated to gravity or relativity but related to measurement devices”.…”

Emergent quantum mechanics (EmQM) explores the possibility of an ontology for quantum mechanics. The resurgence of interest in realist approaches to quantum mechanics challenges the standard textbook view, which represents an operationalist approach. The possibility of an ontological, i.e., realist, quantum mechanics was first introduced with the original de Broglie–Bohm theory, which has also been developed in another context as Bohmian mechanics. This Editorial introduces a Special Issue featuring contributions which were invited as part of the David Bohm Centennial symposium of the EmQM conference series (www.emqm17.org). Questions directing the EmQM research agenda are: Is reality intrinsically random or fundamentally interconnected? Is the universe local or nonlocal? Might a radically new conception of reality include a form of quantum causality or quantum ontology? What is the role of the experimenter agent in ontological quantum mechanics? The Special Issue also includes research examining ontological propositions that are not based on the Bohm-type nonlocality. These include, for example, local, yet time-symmetric, ontologies, such as quantum models based upon retrocausality. This Editorial provides topical overviews of thirty-one contributions which are organized into seven categories to provide orientation.

“…The question itself was explicitly asked in Ref. [18]: whether the space-time Newtonian unpredictabilities/fluctuations á la DP [14] are the non-relativistic limit of the Planckian's? A possible, affirmative, answer may come from Unruh's intuitive quantization of space-time [16], as mentioned in [14,17,18].…”

With the simplest proof ever, we justify the significance of quantum-gravity in nonrelativistic quantum mechanics together with the related theories and experiments. Since the de Broglie wave length is inverse proportional to the mass, it would descend towards and below the Planck scale 10 −33 cm for large masses even at slow non-relativistic motion. The tricky relationship between gravity and quantum mechanics -well-known in the relativistic caseshows up in non-relativistic motion of massive objects. Hence the gravity-related modification of their Schrödinger equation is mandatory. We also recall the option of an autonomous Newtonian quantum-gravity, a theory parametrized by and G. On cancellation of c from the Newtonian limit of Planck scale metric fluctuations is given a new hint.

The case of Quantum Gravity with Spontaneous Collapse of the Wave Function

When about half a century ago the concept of universal spontaneous collapse of the wave function was conceived it was an attempt to alter standard non-relativistic quantum physics. As such, it was largely ignored by relativistic field theory and quantum gravity communities. A central motivation of spontaneous collapse community has been to replace the standard collapse-by-measurement that annoyed many. With few exceptions, it did not annoy the field theory and quantum gravity communities. Concept of certain general-relativity-related universal irreversibility in quantum field theory had been initiated very long ago by Wheeler, Hawking and a few others independently from the concept of spontaneous collapse. Lately the two concepts started to converge and support each other.
