Quora: Can singularities actually be physically real or are they simply a mathematical construct to fit in with our understanding of Physics?

The Singularity is the absence of physical reality. Physical reality is the absence of the Singularity. Physical existence arises from, and returns to, the Singularity. So no, the Singularity cannot be physical.

The Singularity has real existence, but the Singularity is not physical existence. Physical existence is the direct result of dualistic characteristics such as positive and negative charge, right and left spin, matter and antimatter, and numerous other dualistic properties. Since measurable properties are quantifiable, then yes, a Singularity can be understood in terms of mathematical constructs such that we can see how the Singularity fits in with our understanding of physics.

The concept of Singularity in physics arose as a consequence of certain equations within General Relativity theory. These calculations involve the Schwarzschild radius in the circular deflection angle equation (such as for photons passing a star) and the orbital perigee precession equation (such as for calculating the precession of Mercury's perigee around the Sun). The Schwarschild radius implies a length density limit beyond which physical matter will collapse and create a black hole. The black hole is a limit to the physical Universe, and represents an "edge" to physical existence.

A clear definition of Singularity is given on UniverseToday.com: [1]

"In scientific terms, a gravitational singularity (or space-time singularity) is a location where the quantities that are used to measure the gravitational field become infinite in a way that does not depend on the coordinate system. In other words, it is a point in which all physical laws are indistinguishable from one another, where space and time are no longer interrelated realities, but merge indistinguishably and cease to have any independent meaning." 

Physical evidence has accumulated in astrophysics which supports the existence of black holes, and their resulting Singularity. As a consequence of the upper limit of length density allowed by the quantum structure of space in the physical Universe, it was proposed by Stephen Hawking [2] that reversing the perceived timeline in General Relativity theory would lead to the quantification of a Singularity which may have given birth to the physical Universe. The hypothesized Singularlity at the perceived beginning of the physical Universe was previously dismissed as the "Big Bang" by Fred Hoyle [3], and was based upon the earlier observations of Edwin Hubble [4], who observed that galaxies were moving away from each other.

Physical Matter does not Exist in a Linear Timeline 

The flaw in Steven Hawkings thinking is the underlying belief that there is a physical timeline that controls physical matter, and which causes change to physical matter[5]. In the physical timeline of mainstream physicists, there is an imagined active dimension, called time, that animates physical matter in only the forward time direction. The quantification of the physical timeline with respect to physical events has been highly influenced by Hermann Minkowski [6], who developed a four dimensional space-time coordinate system that now bears his name. When this imagined, active time direction is applied to certain equations of General Relativity theory, physicists develop a misperception that time creates a beginning and an ending to all things. 

There is no physical evidence for an active time dimension. The concept of time moving physical matter from a past toward a future is strictly a mental concept created by the hippocampus of a brain that creates, stores, and recalls memories. From a strictly physics perspective, the only temporal reality where physical matter actually exists is the present moment. There is no physical matter in a past reference frame, and neither is there any physical matter in a future reference frame. 

The temporal reality that we interpret as time is caused by half spin physical matter (subatomic particles) spinning in only the forward time direction within a present moment, and where the present moment is oscillating between both forward time and backward time. Half spin physical matter sees only the forward time direction within the present moment. The present moment makes no progress either toward the past or toward the future because the present moment continually oscillates between forward time and backward time. There is no past or future in which physical matter exists. Memories and imagination are the only evidence we have for the concept of linear time.

Edges of the Physical Universe

The black hole does create an "edge" to the physical Universe. However, the Singularity that gives rise to physical existence is not a singular, one-off event that suddenly creates an entire physical Universe. When we correctly examine the fundamental constants and equations of physics, we find that the entire physical Universe reduces to two pairs of two distinct physical manifestations, each originating from the Singularity; there are the pair of electrostatic charge and magnetic charge, and the pair of Gforce and dark matter. 

\begin{equation}1=\frac{e^{2}}{8\pi\alpha\cdot {e_{max}}^{2}}\end{equation}

\begin{equation}1=\frac{m_{a}\cdot \lambda_{C}\cdot {F_{q}}^{2}}{Gforce}\end{equation}

So for whatever reason, the Singularity can split into two types of charges, and into dark matter and Gforce. The concepts of the two types of charges, dark matter, and Gforce explain in greater detail in earlier chapters of this book. 

The splitting of the Singularity takes place within the present moment, as does the existence of black holes. The physical Universe arises continually through the physical processes of the Casimir effect and nuclear fission/fusion, and the physical Universe continually collapses into black holes through the accumulation of matter that exceeds the length density limits established by the structure of space (Aether). 

The present moment is eternal and never advances toward the past or toward the future. There is no physical meaning to "beginning" or "ending" in the physical Universe. "Beginning" and "ending" are concepts of the intellectual mind. 

The limits of the physical Universe are not temporal limits, but are limits of mass and charge. And since space composes from quantum rotating magnetic fields called Aether units, the limits of mass and charge are directly related to fixed lengths (Compton wavelength) and frequencies (quantum frequency). The fixed length times fixed frequency establishes the speed of photons constant.

And thus the edges of the Universe are not walls or voids, but length density limits, velocity limits, force limits, and other limits determined by the quantum structure of space.

Consciousness

The Singularity also appears to play a role in consciousness. Consciousness has two manifestations; there is the consciousness that arises from thinking (brain activity), and there is the consciousness that arises from choosing (the chooser within).

The hippocampus of the brain is responsible for creating, storing, and recalling memories. These memories involve not only our sensory input from our five physical senses, but also involve the feelings and emotions caused by hormones and chemical reactions throughout the body. When we are born, our hippocampus is essentially a clean slate. As we grow we experience sensory input and internal feelings, and the net result of all these recorded feelings and experiences stored in our brain as memories results in our personality, or ego. The operation of our brain and body are strictly electro-chemical-mechanical actions and reactions. 

Soul as the Chooser Within

Connected to our physical body, and which ultimately arises from the Singularity, is what is variously known as the soul or atman. The soul is the "chooser within" and is often associated with our conscience. Whereas the personality is created by the body and will die with the body, the soul is an extension of the Singularity that never dies. The soul is the carrier of our karma from one existence to the next.

Physical existence arises from duality, yet the soul always maintains its Singularity-based existence and seeks to find meaning within the duality of physical existence. Thus the soul is ever faced with continual choices throughout its physical journey. 

The Singularity as a Limit

From a physics perspective, the physicist's understanding can never reach beyond the Singularity. Physical existence exists only within the dualistic paradigm of the two types of charges, and the dark matter/Gforce duality. 

Even the intellectual realm developed within the hippocampus and rest of the brain, which is limited to physical experiences, cannot penetrate into the direct experience of the Singularity. The intellect is limited due to the fact that it builds upon a dualistic framework.

The only way to enter into the realm of the Singularity is for the soul to become perfectly still, and to no longer have the desire to make choices or to participate in dualistic experience. Such a path has only been trod by sages.
