The present paper summarizes the author’s Theory of Everything and Theory of the Ultimate origin of the universe and of our realities of existence. This second book by the author explains the great mysteries of the universe and of humanity and existence. Once we are acqainted with how the Creation Mechanism occurred, we would come face to face with some profound insights about Supernatural Creation and about the Ultimate Nature of Existence, as follows: •The Ultimate Theory of Everything is equivalent to the Philosophy of Everything + the Physics of Everything. •Based on the Theory of Everything, a scientific concept of the Supernatural Origin of the Universe is proposed. •This scientific concept of the Origin of the Universe and of the Realities of Existence lays out the ultimate nature of Spacetime, Gravitation, Forces, Particles, in a scientific and philosophical manner that enables the integration of Einstein Relativity and Quantum Mechanics, that is currently agreed to be the most elusive mystery of Physics. •As a result of this ultimate integration of the physics and philosophy of the universe and of existence, and based on the Theory of Everythng, we are able to explain several unsolved cosmological phenomena: The ultimate nature of Spacetime, Gravitation, Dark Matter and Dark Energy, the origin and nature of Consciousness and the Accelerated Expansion of the Universe, among others. •Arising from the above, we are able to explain, in an extraordinary manner, why the forces and their particles are the way they are, showing that the Electromagnefic Force, the Weak Force and the Strong Force have to be realities which are, philosophically and scientifically part and parcel of the preconceived Supernatural Strategy that led to the Creation of the Universe, that interestingly is totally compatible with the Theory of Everything, which as said above, is equivalent to the Philosophy of Everything of Existence+ the Physics of Everything of Existence. •Likewise the origin and ultimate nature of Consciousness are described, whereby it becomes evident that Consciousness is one of the most fundamental realities of the universe, capable of unifying the universe in incredible manners, including its possible connections with the beyond, thus pointing to the likelihood that Consciousness is intimately linked to Supernatural Reality. •Employing the same methodology that enabled explaining the Supernatural basis of the Creation of the Universe, it follows suit that the Afterlife Soul Theory is seen to emerge from a certain manner of interpreting the Theory of Everything and the Consciousness Theory in the context of the ultimate nature of existence. •The Theory of Everything and the Concept of the Origin of the Universe explain most of the conundrums of the universe, particularly the mystery of what spacetime and gravity fundamentally are, as well as of why particles occur in three classes, including explaining the extraordinary contrast between the ultimate reality of the atom being composed of positive proton and the negatively charged electron as opposed to negative proton with the positively charged positron.
