This article discusses the question of where the Quran sets a conceptual limitation on the interpretation of biological evolution of the first human creature, Adam, and presents a novel understanding for the process of biological evolution in general. The work is part of my endeavor to promote new approach in studies in the Islamic approach to Natu...
ندرس في هذا البحث مفهوم (السماء) و(السماوات) ودلالتهما كما وردتا في القرآن الكريم، آخذين بجميع الآيات وجميع الوجوه التي وردت عليها، والخصائص التي وصفت بها، متحرين دلالات المفردات كما هي في اللغة العربية وضمن إطار المعرفة التي كانت سائدة وقت نزول القرآن وبعده حتى الآن في العلوم الفلكية المعاصرة. وقد ظهر لنا أن مفردة (السماء) تدل في وجهها العام على ا...

In this review we present the problem of time in quantum physics, including a short history of the problem and the known objections about considering time as a quantum observable. The need to deal with time as an observable is elaborated through some unresolved problems. The lack of a consistent theory of time is currently hindering the formulation...
The aim of this limited study of Time in Islamic Kalam is to expose some of the original thoughts of Muslims, namely the mutakallimūn, about the notion of time in the hope that it may provoke more detailed and fully accounted studies.
The Casimir effect, which predicts the emergence of an attractive force between two parallel, highly reflecting plates in vacuum, plays a vital role in various fields of physics, from quantum field theory and cosmology to nanophotonics and condensed matter physics. Nevertheless, Casimir forces still lack an intuitive explanation and current derivat...
In this review we present the problem of time in quantum mechanics including a short history of the problem and the known objections about considering time as a quantum observable. The need to deal with time as an observable is elaborated through some outstanding unresolved problems. The stumbling block in formulating a consistent theory of time is...
The book presents the basic principles adopted by the early Mutakallimun in their approach to deal with topics of Natural Philosophy. The book also tries to show that these principles can be utilized to propose solutions for current fundamental problems in physics and philosophy and get better comprehension of some basic concepts in these fields.
The book is an introduces the basics of Astronomy and Astrophysics, suitable for undergraduate students. The text is in Arabic and is a collection of lectures by the author delivered over many years at Yarmouk University/Jordan.
The book contains the basic concepts of Modern Physics
This is a book about the basic principles of Quantum Mechanics suitable for undergraduate students. It is a collection of my lectures at Yarmouk University in Jordan.
This book is in Arabic. It explains how the universe was created out of the quantum vacuum with the presence of gravity. Other chapters deals with verses of the Quran which describes natural facts so accurately that it would be very hard to believe that these are written by human being.
We test a hypothesis that stars located away from the center of the galaxy, moving under the effect of an emergent viscous drag force perpendicular to their velocities, might exhibit the behavior observed in the rotation curves of the spiral galaxies. We construct a simple model for such an assumption, then by using simple fitting technique, we are...
The book contains my lecture notes in the Theory of General Relativity which was delivered at Yarmouk University Jordan 2005-2019.
Recently Gerard 't Hooft proposed a structure for a universe overwhelmed with a control by a Theory of Everything (arXiv:1709.02874). He concludes, among many other things, that such a universe could be fully deterministic and that, accordingly, the divine intervention will be eliminated. Here I discuss such a possibility and show that a fully dete...
We assume that the individual stars which are located at the peripheral parts of the spiral galaxies are experiencing a drag force acting upon them radially. Such a force might be produced by some sort of a dynamically generated viscous medium, and as the stars are in the state of free fall toward the center of the galaxy, then it would balance the...
This chapter discusses briefly the main principles of Daqiq al-Kalam exposing the role it could play in contemporary science and religion debates.
This chapter discusses the difference between laws of nature and laws of physics, exposing that some senior scientist makes confusing remarks sometimes by confusing the two concepts.
This chapter discusses the concepts of space and time according to the mutakallimun. Two major contributors are chosen, Abu Hamid al-Ghazali and Ibn Hazm al-Zahiri.
In this article I present a debate between Abu Hamid al-Ghazali and the muslim philosopher Averroes about two questions: the size of the universe and the fate of the Sun. al-Ghazali suggested that there is no reason for believing the size of the universe is fixed. Averroes refused this challenge claiming that the universe must have a fixed size oth...
This article presents the idea that a transformation of the traditional Islamic thought is necessary at this age and that this transformation might be possible through the development of Kalam into new construct based on daqiq al-Kalam.
We report the application of Titius-Bode's law on 43 exoplanetary systems containing four or more planets. Due to the fact that most of these systems have their planets located within compact regions extending for less than the semi-major axis of Mercury we found the necessity to scale down the Titius-Bode law in each case. In this short article we...
And when they [the philosophers] mean by " Nature " that which happens from the burning fire, it is what we consider to happen out of the adherences (i¢timādāt) which generate dissociations. 1 QāḍÏ ¢Abd al-Jabbār I n the previous chapter, I considered the differences between what we call laws of nature and laws of physics, and I have shown that suc...
This chapter discusses Divine Action according to Islamic Kalam set in modern perspective.
A model for the universe based on the back-reaction effects of quantum fields at finite temperature in the background of Robertson-Walker
spacetime and in the presence of a non-zero cosmological constant is constructed. We discuss the vacuum regime in the light
of the results obtained through previous studies of the back-reaction of massless quantu...
I investigate the possibility of the propagation of neutrino with
superluminal speed through matter in the context of the relation between
gravity, spin and torsion. Using a lemma of Penrose and earlier works on the
relation between spin, torsion and gravity I glimpse on a frame work in which
superluminal speed of the neutrinos moving through matte...
Using the result obtained in a prevoius paper, in which I found an upper limit on the region of particle creation in the vicinity of the event horizon of a Schwarzschild black hole, and by assuming that all the created energy will be absorbed by the black hole, a natural power law for the growth of the event horizon is deduced. This result may expl...
The Friedmann paradigm for a dynamical universe emanating from a spacetime singularity is critically reviwed. Quantum effects, playing the essential role at the very early stages, suggests that the universe may follow different course to that presented by the standard Friedmann solutions. The investigation of the back-reaction effect of the vacuum...
We construct a model for the universe based on the existence of quantum fields at finite temperature in the background of Robertson-Walker spacetime in presence of a non-zero cosmological constant. We discuss the vacuum regime in the light of the results obtained through previous studies of the back-reaction of massless quantum fields in the static...
I discuss some of the main interpretations given to explain the indeterministic nature of quantum measurements and show that all has some loopholes in one corner or another. I propose an alternative interpretation based on the notion of continued re-creation of the physical properties. The rate at which the system is re-created is a measure of the...
In this paper, we consider the Casimir energy of massless scalar fields which satisfy the Dirichlet boundary condition on a spherical shell. Outside the shell, the spacetime is assumed to be described by the Schwarzschild metric, while inside the shell it is taken to be the flat Minkowski space. Using zeta function regularization and heat kernel co...
In this paper we show that the entropy of a cosmological horizon in 4-dimensional topological Kerr-Newman-de Sitter spaces can be described by the Cardy-Verlinde formula, which is supposed to be an entropy formula of conformal field theory in any number of dimensions. Furthermore, we find that the entropy of a black hole horizon can also be rewritt...

We study the back reaction effect of massless minimally coupled scalar field at finite temperatures in the background of Einstein universe. Substituting for the vacuum expectation value of the components of the energy-momentum tensor on the RHS of the Einstein equation, we deduce a relationship between the radius of the universe and its temperature...
We study the possible values of the cosmological constant arising from the back reaction collective effect of several massless spinor quantum fields at finite temperatures, including their vacuum energies (Casimir energy), simultaneously existing in an Einstein universe. We consider successive quasi-static states of the Einstein universe and accord...
We follow a heuristic approach for particle creation by a localized strong gravitational field. The approach is based on a definition of the physical vacuum drawn from Heisenberg uncertainty principle. Using the fact that the gravitational field redshifts the frequency modes of the vacuum, a condition on the minimum strength of the gravitational fi...
The back reaction effect of the neutrino field at finite temperature in the background of the static Einstein universe is investigated. A relationship between the temperature of the universe and its radius is found. As in the previously studied cases of the massless scalar field and the photon field, this relation exhibit a minimum radius below whi...

We study the back-reaction effects of the finite-temperature scalar field and the photon field in the background of an Einstein universe. In each case we find a relation between the temperature of the universe and its radius. These relations exhibit a minimum radius below which no self-consistent solution for the Einstein field equation can be foun...
The condensation of a non-relativistic ideal Bose gas in an Einstein universe is investigated. Explicit expressions for the condensate fraction N0/N and the specific heat are obtained by using the Poisson summation formula to express the summations as integrations plus corrections. It is shown that the finiteness of the system smoothes out the cusp...
In this paper we investigate the Bose–Einstein condensation of massive spin-1 particles in an Einstein universe. The system is considered under relativistic conditions taking into consideration the possibility of particle–antiparticle pair production. An exact expression for the charge density is obtained, then certain approximations are employed i...

The finite-temperature corrections to the vacuum energy density of scalar, neutrino, and photon fields in an Einstein universe are calculated by using the statistical-mode-sum technique with the aid of the Poisson summation formula. The theory of relativistic time-temperature Green's functions in static space-time is also considered and used to cal...
The spin-1/2 Green's function in an Einstein universe is computed explicitly and used to evaluate the vacuum-averaged stress-energy tensor. In the massless limit we find Ford's value =17(1920pi2a4)-1.
The question of the eternity or temporality of the universe was thoroughly discussed by Muslim theologians. Most of them, principally those who were called Mutakallimūn, agreed on the notion of creation ex nihilo, i.e., creation out of nothing. On the other hand some Muslim philosophers adopted the Greek originated notion of an eternal universe tha...
