What else other than the Big Bang Singularity?

What else other than the Big Bang Singularity?



Since my childhood I have been affascinato with astronomy and cosmology. I lived in the relative darkness at night in suburban Illinois and the night sky was a display of planets, stars and even satellites. Early on, seeing my enthusiasm, my parents bought me a small telescope with which I could see even clearer and, also, more distant celestial objects, and we went to the nearby observatory and planetariums to learn more about the universe. Of course, as with all science, over the years with the advancement of more sophisticated technology, the hypothesis of the origin of the universe has changed and will continue to do so. This short blog is written as a personal reflection on the latest, more reasonable hypotheses on the topic of the beginning of our universe.

Those familiar with cosmology or the scientific study of the origin and structure of the universe are aware of the competition of two primary hypotheses about the nature of the universe in which we live. These two are the Steady State and Big Bang. In brief, the steady-state theory, claims that the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle, a principle that asserts that the observable universe is basically the same at any time as well as at any place. While the steady state model enjoyed some popularity in the mid-20th century, the Steady State Theory is now no longer accepted by most cosmologists. Today the majority of astronomers consider the Big Bang theory to be the best description of the origin of the universe as the observational evidence points to a hot Big Bang cosmology with a finite age of the universe, which the Steady State model does not predict.

It seems that the field of cosmology, therefore, yields good evidence that there was an initial beginning to our universe. According to the Big Bang theory, our universe began as an infinitesimally small, infinitely hot, and infinitely dense something – a singularity. The universe began to exist as a hot, dense phase, which can be considered the “birth” of our universe in which was contained all of the mass and spacetime of the Universe before it rapidly expanded with subsequent inflation, creating the present-day Universe. Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past. The initial singularity is part of what is called the Plank  Epoch , or the earliest period of time in the history of the universe. So according to the standard theory, based on measurements of the expansion using Type IA supernova and measurements of temperature fluctuations in the cosmic microwave background, our universe came into existence as a singularity of an estimated age of 13.799 ± 0.021 billion years ago.

Well, as an ‘affascinato’ of cosmology, this has always been pretty convincing through the science that supports the Big Bang until one arrives at the logical question of “How did all that mass come into existence from nothing?”. One thinks that perhaps not being a professional in the subject, one has missed a subtle and important link in the argument for the Big Bang model. This self-doubt ends rather quickly when the usual cosmologist at the end of the Big Bang lecture admits, “Where did the initial singularity come from? We don’t know. Why did it appear? Well, to be honest, we don’t know. This is a question that stretches physics to its limit simply because before the initial singularity there was no space and no time. Therefore, the word ‘before’ becomes meaningless.” In fact, the Big Bang singularity can explain only what happened immediately after—not at or before—the singularity. Also, this implies that the universe was born with a tendency to expand, which overcame the tendency of matter to collapse. Why it initially chose to do so is also still a mystery… the Big Bang model has numerous theoretical difficulties to it.

So while the Big Bang is the most accepted model, there are many holes (not black ones) in this proposition. But now there is a new perspective which gives a more parsimonious answer to the questionable issues associated with that singularity. The perspective is quantum physics. In quantum physics, particularly the transactional interpretation (TI) of quantum mechanics, as discussed by Ruth Kastner, explains that the macroscopic world of mass, space and time is based on the foundation or scaffold of the quantum interactions found in ‘quantumland’. This interpretation purports that there is more to known reality than ‘spacetime’, and that quantum theory describes that subtler, unseen reality. In this hypothesis, quantum processes take place in a realm scaffolding the ‘spacetime’ realm. Quanta are not contained in our spacetime world but in the realm of possibilities outside spacetime. Kastner explains that according to the transaction interpretation of quantum systems, e.g. electrons, travel by a physical entity called an offer wave, which is offered from a source called an emitter, to a destination called an absorber. The microscopic emitters and absorbers are quantum objects and not in spacetime. When there is absorption of the offer, this process gives rise to a confirmation wave that travels back to the emitter. This process of an offer responded to by a confirmation is the basic ‘handshake’. The confirmation is also like a mirror image of the offer representing an incipient transaction whose essence is merely possible energy rather than real energy. The process of the creation of new particles can only be treated by relativistic quantum mechanics.

Once there is a matching confirmation, then the property is defined as actualized, brought into spacetime, and is a classical property. The incipient transaction is actualized and becomes an observable event in the macroworld or ‘our’ world of mass in space and time. A macroscopic object begins at the point at which a confirmation has been generated. Real energy is only conveyed in the actualized transaction, in fact; only through an actualized transaction can real energy be radiated or transferred from one object to another. So indeed, a reliable macroscopic object is a consistent absorber and can be defined as a system of many actualized transactions. Kastner uses the example of a geiger counter to illustrate the difference of the two ‘worlds’. A geiger counter exists as an object in the macroscopic world being a conglomerate of actualized transactions. But it also maintains its roots in the quantumland domain of possibilities because it is comprised of atoms, which can act as emitters or absorbers. Measurement occurs both whenever an absorber is accessible to an emitter and when confirmations are generated.

In actuality, it is the interaction of subatomic material that brings forth the material world as we know it and as it exists. So, in terms of the beginning of our universe, using the TI model, the speculation that would make sense is that at a point about 13 billion years ago there was a quantum fluctuation that created the macroscopic elements which ‘broke through’ and created our realm of existence. While, of course, the why, how and what are still a mystery for this as is still much of our comprehension of ‘quantumland’, we are no longer faced with the impossibility of explaining the ‘before’ the singularity event of the Big Band using the infinite macroscopic mass/space/time model of the Big Bang but instead the more heuristic, efficient quantum model which bypasses the impossible.

  • Time is a mystery. Some thoughts by thinkers. ——————————————————————-  

The illusion of the passage of time arises from the confusing of the given with the real. Passage of time arises because we think of occupying different realities. In fact, we occupy only different givens. There is only one reality.” Kurt Gödel

“Gödel concluded that time travel is indeed theoretically possible, rendering time, as we know it, meaningless. Time, that mysterious and seemingly self-contradictory being, as Gödel put it, which, on the other hand, seems to form the basis of the world and our own existence, turned out in the end to be the world’s greatest illusion. For Gödel, time was the philosophical question” Palle Yourgrau, ‘A world without time’

“Ultimately all moments are really one. Therefore, now is eternity.” David Bohm
“…for us physicists believe the separation between past, present, and future is only an illusion, although a convincing one.” Albert Einstein

“I am therefore inclined to think that “the Real”- alais human independent reality- is not embedded in space-time. And indeed, I go as far as speculating that, quite the contrary, the nature of space-time is… not ‘noumenal’ but ‘phenomenal’, that space-time is a ‘reality-for-us.’” Bernard d’Espagnat  

” …As a result, all change must be gauged by correlations. Ultimately, everything must be correlated with the size of the Universe. Any vestige of a moving present has faded completely…Remember that Einstein spoke of an illusion…Might it be that our strong sense of the flow of time is an illusion akin to giddiness, perhaps connected with the way our memories operate?” Paul Davies   

“The world just does not happen, it simply is…” Hermann Weyl 

“All these Nows,  just exist.  They do not appear and then vanish; they just are.   From a global perspective, there is no answer to the question, “What time is it?”  There are just different experiences at different Nows. From any given vantage point, you look back, and remember other times – so that the question, “Why is it this time right now, rather than some other time?” seems to make sense.  But there is no answer. When I came to this understanding, I forgot the meaning that Time had once held for me. Time has dissolved for me, has been reduced to something simpler that is not itself timeful. I can no longer conceive that there might really be a universal time, which is somehow “moving” from the past to the future.  This now seems like nonsense.” Eliezer Yudkowsky 

“One cannot though conclude how the variations are taking place, over what timescales they are taking place or even how old the universe is. The universe could be 10×10 years old or 5 x 10-44 sec (the Planck time)old, or any time in between. Time is strictly a parameter that can be introduced in the scale-invariant relationships. It has no meaning by itself. The universe appears to be evolving as the number of particles and ratios are varying.” Menas Kafatos, Sisir Roy and Richard Amoroso   

“…the present moments of reality are now replacing one another, where if one had direct awareness of reality one would know reality as transcendental efficient moments” Fyodor Ippolitovich Stcherbatsky

“From non-nirvanic awareness, one experiences imaginary causal connections between moments and thus fabricates the illusion of persistence and duration of objects. But when one experiences reality, one only experiences the efficient moments, rapidly replacing one another, like the flames of a fire. Buddha: the whole world is burning. The non-nirvanic observer, unaware of the fiery, boiling nature of reality, is unaware that they will not exist beyond this present instant, and that any volition or hope is unneeded and illusory, and is based on the misery of unreality.” J. Grupp  

The Buddha said, “Even so was my past existence at that time real, but unreal the future and present existence; and my future existence will be at one time real but unreal the past and present existence; and my present existence is now real, but unreal the past and future existence. All these are merely popular designations and expressions, mere conventional term of speaking, mere popular notions” (Digha-nikaya). Hence the Buddha has only one time, that is “Eternal Present”.” Chen Hsiongcai

“I have realized that the past and future are real illusions, that they exist in the present, which is what there is and all there is.” Alan Watts

“Time, as self-determination of the eternal “Now”, is essentially contained in this Now. There where time is, contained and extinquished, personality appears, as content of eternity.” Nishida

“The Universe is a dynamic system in a permanent dynamic equilibrium, there is no beginning and no end of the universe.” A.S.Sorli

“So in summary, the universe we see is just a fragment nested in a timeless (everything) whole, rather than a single material world magically arisen above some primordial nothing. All universes exist without beginning or end in the ultimate arena of time, and each moment we experience exists forever.” Gevin Giorbran  

“This means that because, in reality, there is no coming or going in time, when we cross the river or climb the mountain we exist in the eternal present of time; this time includes all past and present time.” Dogen  

“Dogen writes, ‘Entire being, the entire world, exists in the time of each and every now.’ Thus the mind, body, being, world, and time form a unity. Not only are entities time, and not only is time in me, but activities are time. ‘As the time now is all there is, each being-time is without exception entire time.’ Dogen emphasizes the now moment because there is never a time that has not been or a time that is coming. ‘…all is the immediate presencing here and now of being-time.’ Thus time is a continuous occurrence of ‘nows’. The Buddha-nature is a present actuality.” Carl Olson

“Dogen frees himself from the representational mode of thinking without subverting time and remaining convinced that each moment is complete in itself and cannot be undermined.” Carl Olson    

“The universe would be completely self contained and not affected by anything outside itself. It would neither be created nor destroyed. It would just BE.”  Stephen Hawking

“Whether or not reality has one universe or many, it had no beginning and was not created. It neither was nor will be. It just is.” Victor J. Stenger

“What suggests itself is that psychologically – and perhaps eventually for the deepest level physically – we can’t use time as the essence. Rather, the moment NOW is the essence, because all the past and the future that we ever will know are in this moment. The past and the future are now – namely, in so far as it has left any impression, whatever has happened is now. And our experiences are now. Thus we could say that now may be the starting point. One picture you could make of an electron would be that it sort of flashes into and out of existence so fast that when picked up in the usual equipment it looks continuously existent. It might have a certain regularity, so that it appears to obey an order of necessity. But it might be that it is basically creative; the creative act may create this order of necessity.” David Bohm

“We are always moving (inflationary cosmology)(arrow of time) but also always remain in the now. The ‘phenomenal’ now is relative, experienced as eternal but intuitively we grasp and psychologically represent a moving existence by remembering a past and projecting into a future.” Rodger Ricketts

“Time is like a ‘field’ – there is no fixed, locatable present. It always vanishes upon close examination. The moment you try to pinpoint it, it has already passed and a future moment is now present.” Trinh Thuan

In 1949 the great logician Kurt Gödel constructed the first mathematical models of the universe in which travel into the past is, in theory at least, possible. Within the framework of Einstein’s general theory of relativity Gödel produced cosmological solutions to Einstein’s field equations which contain closed time-like curves, that is, curves in spacetime which, despite being closed, still represent possible paths of bodies. An object moving along such a path would travel back into its own past, to the very moment at which it ‘began’ the journey. More generally, Gödel showed that, in his ‘universe’, for any two points P and Q on a body’s track through spacetime (its world line), such that P temporally precedes Q, there is a time-like curve linking P and Q on which Q temporally precedes P. This means that, in principle at least, one could board a ‘time machine’ and travel to any point of the past. Gödel inferred, in consonance (as he observes) with the views of Parmenides, Kant and the modern idealists, that under these circumstances there could be no such thing as an objective lapse of time, that time or, more generally, change, is an illusion arising from our special mode of perception.” John L.
