“…Year by year, the multiverse scenario reaches more and more important status in theoretical physics [1][2][3][4][5][6][7][8][9][10]. The question whether the multiverse exists or not is still open and under debate.…”

We consider observational consequences of the entanglement between our universe and a hypothetical twin anti-universe in the third quantization scheme of the canonical quantum gravity. Based on our previous investigations we select some special form of the interuniversal interaction which allows the entanglement entropy of the pair of universes to diverge at some critical points of their classical evolution. We find that the modification of the cosmic microwave background (CMB) power spectrum due to the entanglement with our twin anti-universe is enlarged for small modes k and small multipole numbers l with the Planck constraint onto the interaction coupling constant λ o O(10 −56 ). Some other coupling functions which allow more critical points are also briefly commented on in the context of their observational effect on CMB and other observations.

“…The most common implication of this fact is the so-called anthropic principle, which postulates that the values of physical constants in the observable world must provide the existence of a certain observer (see, e.g., the recent review [11] and the references therein). The discussion of this principle has revived in recent years in connection with the concept of a multiverse, which is a feature of some inflationary theories [12,13].…”

We study the properties of fundamental physical constants using the threefold classification of dimensional constants proposed by J.-M. Lévy-Leblond: constants of objects (masses, etc.), constants of phenomena (coupling constants), and “universal constants” (such as c and ℏ). We show that all of the known “natural” systems of units contain at least one non-universal constant. We discuss the possible consequences of such non-universality, e.g., the dependence of some of these systems on the number of spatial dimensions. In the search for a “fully universal” system of units, we propose a set of constants that consists of c, ℏ, and a length parameter and discuss its origins and the connection to the possible kinematic groups discovered by Lévy-Leblond and Bacry. Finally, we give some comments about the interpretation of these constants.

“…The diversity of possible physical shapes of a universe within the multiverse can be interpreted in terms of diversity of possible ways to choose physical parameters and can be related to the issue of varying physical constants and varying physical laws [4]. Another idea related to the Multiverse we cover in the issue is the Anthropic Principle which, despite being in some sense tautological, it has been argued how it could give some insight and possible constraints onto the nature of the physics we experience here in "Our Universe", whatever it is.…”

“…A more recent idea of the multiverse is constituted of the quantum multiverse, in which different individual universes are classically causally separated, but quantum mechanically entangled [4]. This approach has entered strongly in the scenario, because it gives possible predictions and an opportunity to falsify the concept.…”
