Æther as an Inevitable Consequence of Quantum Gravity

Abstract

The fact that quantum gravity does not admit an invariant vacuum state has far-reaching consequences for all physics. It points out that space could not be empty, and we return to the notion of an æther. Such a concept requires a preferred reference frame for describing universe expansion and black holes. Here, we intend to find a reference system or class of metrics that could be attributed to “æther”. We discuss a vacuum and quantum gravity from three essential viewpoints: universe expansion, black hole existence, and quantum decoherence.

Scalar Product for a Version of Minisuperspace Model with Grassmann Variables

“…Contributions of the order of ∼ m 4 also have to be compensated for but by taking condensates into account [15]. The resulting theory, which has features such as partial gauge fixing, preferred reference frame, and the existence of aether [17,18] (in the form of condensates and vacuum polarization) could be a suitable candidate for quantization.…”

“…This demand has no solid foundation because it is known that there is no vacuum state invariant relative to the general transformation of coordinates. On the contrary, an argument was put forward that the preferred conformally-unimodular metric (CUM) could describe a vacuum polarization and resolve the DM problem [28,31]. In this metric, a black hole as an object having a horizon is absent [32].…”
