Is the Emergence of Life an Expected Phase Transition in the Evolving Universe?
We propose a novel definition of life in terms of which its emergence in the universe is expected, and its ever-creative open-ended evolution is entailed by no law. Living organisms are Kantian Wholes that achieve Catalytic Closure, Constraint Closure, and Spatial Closure. We here unite for the first time two established mathematical theories, namely Collectively Autocatalytic Sets and the Theory of the Adjacent Possible. The former establishes that a first-order phase transition to molecular r…

Strong Determinism
A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), ''it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.'' Such an extraordinary feature may appear unattainable in a world like ours. In this paper, I show that it can be achieved in a simple way and discuss its implications for metaphysi…

Study of Orbital Dynamics in Singular and Regular Naked Singularity Space-times
The universe is filled with various compact objects and the most attractive of them are the black holes and singularity. But it is also known that at the singularity density becomes so infinitely high that the present physics knowledge breaks down. Thus, the singularity remains a flaw of the present theories. Several methods have been exercised to resolve the singularity. One such mathematical method is through conformal transformations. This paper deals with regularizing a naked singularity sp…

Appearance of neutrino asymmetries in the process of expansion of the Universe, hierarchy of neutrino masses and CP violation
In this work, we study the appearance of neutrino asymmetries during the expansion of the Universe. A mathematical model based on differential equations was used to describe the processes of neutrino oscillations considering CP violation and neutrino collisions. An analysis of the emergence of neutrino asymmetry due to collisions of neutrinos with each other and due to CP violation during neutrino oscillations is presented. It was discovered that the asymmetry bifurcates into two states with po…

Can nonlocal gravity explain dark energy?
In view to scrutinise the idea that nonlocal modifications of \GR~could dynamically address the dark energy problem, we investigate the evolution of the Universe at infrared scales as an \IDG~model of the Ricci scalar, without introducing the cosmological constant $Λ$ or any scalar field. The accelerated expansion of the late Universe is shown to be compatible with the emergence of nonlocal gravitational effects at sufficiently low energies. A technique for circumventing the mathematical compl…

Cosmological electromagnetic hopfions
It is shown that any mathematical solution for null electromagnetic field knots in flat spacetime is also a null field knotted solution for cosmological electromagnetic fields. This is obtained by replacing the time $t\rightarrow τ=\int dt/a$, where $a=a(t)$ is the scale factor of the Universe described by the Friedman-Lemaître-Robertson-Walker (FLRW) cosmology, and by adequately rewriting the (empty flat spacetimes) electromagnetic fields solutions in a medium defined by the FLRW metric. We …

Hydrodynamics on (mini)superspace, or a non-linear extension of quantum cosmology
We outline the content and theoretical support for the proposal of "hydrodynamics on (mini)superspace" (or a non-linear extension of quantum cosmology) as an effective framework for quantum gravity in a cosmological context. The basis for the proposal is a general correspondence between hydrodynamics and cosmology, and a picture of the universe as a quantum gravity condensate. The support comes from several directions. One is from mathematical physics: the hydrodynamics of quantum fluids can be…
