Spacetime in an Expanding Universe

The few short paragraphs quoted below are from an information website called space.com. The fact that space expands and advances simultaneously with matter is well known and can be found stated in many places, but it is expressed particularly well here. It parallels what I have been saying about time and suggests that matter and spacetime are not two separate and distinct “things” but rather that spacetime is a product of matter’s continuous emerging presence, precisely because matter’s core energy is transcendentally existential, i.e., that continuing to be-here from one moment to the next is a positive physical event generated by matter. Matter’s continuity in time is not a passive “non-happening,” a mere continuity; being-here is an active event produced by existential energy. Matter actively and autonomously perdures in existence and emanates spacetime creating a “place” for itself and a “now” where before there had been nothing.

The Big Bang did not occur as an explosion in the usual way one thinks about such things, despite what one might gather from its name. The universe did not expand into space, as space did not exist before the universe, according to NASA. Instead, it is better to think of the Big Bang as the simultaneous appearance of space everywhere in the universe. The universe has not expanded from any one spot since the Big Bang — rather, space itself has been stretching, and carrying matter with it. [1]

Please be aware of the metaphorical nature of that last sentence. Space does not “stretch” or “carry.” They are words intended to evoke the simultaneity between matter’s presence and spacetime. A different metaphor ― one suggested by transcendent materialism ― might use the word “exude.” As matter emerges into existence it can be said to exude spacetime as the cocoon that enwraps it, the vehicle (the “carriage”) it which it rides, the nimbus or aura that surrounds it like a cloud, the radiance that emanates from its creative action.

Since the universe by its definition encompasses all of space and time as we know it, NASA says it is beyond the model of the Big Bang to say what the universe is expanding into or what gave rise to the Big Bang. Al­though there are models that speculate about these questions, none of them have made realistically testable predictions as of yet.[2]

The gaps in knowledge referred to here, I believe, derive from the necessary limitations of physics. The sciences begin with existence as a given. They do not question it, therefore what it is flies under their radar. They do not understand autonomous emergent existence as a physical event and therefore it is not even considered as the source of spacetime. All they can do is observe the correlation ― the simultaneity ― they have no way of identifying the causality.

These descriptions are difficult for us to imagine because we have pre-formed images of reality stemming from our ancient dualist metaphysics that are incorrect; we considered being to be a creative “idea” and single act in the distant past but not a physical, material event occurring now in real time. Similarly, we cannot picture matter as producing spacetime because we think of matter as passive and inert; matter in the dualist worldview can’t create anything. With no physical “cause” of space we had to think of space as a pre-existing “region” (created by “God”?) and time as prior to and independent of matter’s duration ― an independent outside measurement of matter’s continuity ― rather than, in both cases, its products, its emanations.

We also tend to think of existence as a onetime thing accomplished in the distant past. We assimilated the “big bang” to the archaic notion of a “moment of creation” by a rational divine Craftsman ― a single occurrence that happened long ago, and that all subsequent motion is simply passive inert matter coasting on the kinetic energy imparted to it by the initial explosion. According to transcendent materialism, however, existence is in fact an ongoing, continually emerging series of physical events occuring in real time wherever matter is found, because matter is in reality an autonomous living energy that, far from being the result of, was itself responsible for, the big bang. “Creation,” the autonomous, physical, self-transcending self-extrusion of every particle of matter’s energy, is going on right now from moment to moment everywhere, wherever there is matter pressing its being-here forward into ― and thus creating ― the next moment, and sequential spacetime is the way we experience it.

The key to the new imagery is to accept that existence is a material act, a physical function of a material energy. Once we allow ourselves to understand matter as physical energy, and specifically existential energy, (meaning the positive and abundantly expanding force that overcomes nothingness), then it is not so difficult to understand that matter emits spacetime as the sweat of its labors, the vapor trail of its lift-off into nothingness.

There is no such thing as nothingness; but there is a conceptual clarity brought by the illustration. “Conquest over nothingness” is the metaphorical translation of the spontaneous human perception of the “positivity” of being-here. That existence is a positive force means that we know instinctively (connaturally) that none of us nor any of what we see around us has to be here. That remains true for us moment after moment. Nothing has to be-here and that implies that energy has to be expended moment after moment in order to make something be-here. Existential energy is activated continually and our human experience of matter enduring includes the spacetime that is its corona ― its emanation.

Another aspect of this physical/metaphysical position is the exclusively human perception of the supreme significance of the present moment. Humans understand connaturally that to be-here is radically limited to “now” and only now. Humans have a privileged position from which to observe the phenomenon precisely because they are themselves conscious observant matter. It is their own existential emergence in time that they know internally to be undeniable for they experience their own conscious presence moving forward in time. They know when they are-here and when they are not for they know what it feels like to be-here. They know that the past, no matter how recent, is no longer here, and that the future does not as yet exist. Existence is absolutely confined to the present moment. Despite the mathematical ratiocinations of some theoretical physicists,[3] people spontaneously dismiss any notion that existence is not confined to “now” or that “now” does not exist.

With regard to matter’s existential energy being inexhaustible which I claim is true even after all other energy gradients have been reduced to equilibrium (in agreement with the first law of thermodynamics), there is this additional corroborating information found in the same citation from space.com:

If the density of the universe exactly equals the critical density, then the geometry of the universe is “flat” with zero curvature like a sheet of paper, according to NASA. If so, the universe has no bounds and will expand forever, but the rate of expansion will gradually approach zero after an infinite amount of time. Recent measurements suggest that the universe is flat with only a 2 percent margin of error.[4]

 

In a recent article edited and reprinted by Aeon Magazine entitled “No Absolute Time,”[5] the relativity of time (i.e., that time is perceived differently at different “places” in the universe), elaborated mathematically by Einstein’s theory in 1905 and anticipated in more general terms in the 18th century by David Hume, would be supported by the claim of transcendent materialism that matter’s very sequential presence, which we humans experience as time, is a result of a series of imperceptibly discrete physical events. As a physical event initiated by each particle of matter, the continuous material emergence of existence itself makes temporal sequence relative to each particle’s location, direction and velocity. Time will appear differently to observers depending on where ― in which portion of matter and under what conditions ― emergence into existence is occurring. This consistency with current scientific thinking serves as a corroboration of the metaphysical claims of transcendent materialism. Matter is not passive, dead and inert; it is an inexhaustible “living” existential energy.[6]

The moment of creation

These reflections on the nature and action of matter’s energy, lift a veil on the reality we experience everyday. The humdrum, boring business of “passing time” when supposedly nothing is happening, actually turns out to be our distracted attendance at the very moment of creation. “Now” is the “place” where existence is actuating itself in all the things with which we live, move and have our being. It reveals that creation was not something accomplished at some point in the distant past, but is an ongoing event occurring before our eyes and experienced directly by us as we emerge into physical existence now. Time “passing” is our experience of the continuous extrusion of existence by matter’s autonomous transcendent energy and that includes the matter of our own biological organisms.

This is extremely significant for us. That our own lowly flesh, so shamefully denigrated and merilessly flayed over millennia by the worshippers of an arrogant disdainful imaginary “spirit,” should now be finally recognized as the autonomous endless engine of LIFE and the place where LIFE enters the world, opens the doors to a self-apprecia­tion that was our birthright but which our Western mindset has ever denied us. Now we understand what our bodies have been trying to tell us with their hunger to be-here and what we have suppressed by embracing the Platonic paradigm. We realize this treasure we carry in vessels of clay is the very energy of LIFE itself. It invites us to a contemplative self-embrace that, from the moment it is experienced, reverberates throughout our organism in a realization that is self-explanatory and self-confirm­ing. Once we pass through that door, we are not likely to return to a world where our bodies are treated as dead and putrifying, contaminating everything around them. We know we are home because now we know what being home feels like … .

We belong here with our material siblings spawned from the earth. We have no need to go any­where else or do anything our bodies were not made for; for in experiencing the continuity of time our very bodies, made of matter, are participating in the welling up and overflow of LIFE. The stillness of “now,” so cherished by contemplatives, reflects matter’s temporary achievement of absolute existential equilibrium in the present moment dissipating its energy by filling the void of nothingness. Suffused with the security and serenity of “now” our organism’s innate creativity can emerge naked and unafraid, exploring a vulnerability it otherwise could not afford to leave unprotected. The tranquility of a “now” understood as the place where being-here emerges in the freshness and power of the first instant, is like a “worm hole” to another dimension of reality, one that intersects our horizontal evolution vertically like a needle injecting LIFE. It is the invisible engine throbbing endlessly at the core of matter. When we understand what matter is, we realize that we have been walking on a field with a treasure buried in it. (These images are all metaphors trying to describe a subjective realization, they do not refer to the metaphysical structure of matter’s energy.)

Our sense of the sacred which we had mistakenly identified exclusively with the narratives of our ancient pre-scientific religious tradition, is not demolished by the scientific discovery that those stories were mythic, but is rather enhanced, intensified and grounded more firmly. Science as interpreted by a cosmo-ontology (metaphysics based on transcendent materialism), pictures a universe made of living material energy, autonomously evolving ever new forms of itself: living organisms, newly organized and equipped to pursue matter’s obsessive embrace of being-here.

Physics examines what is-here and analyzes how it is internally interrelated. Metaphysics, on the other hand, interprets what being-here means to us. In acknowledging the need to pursue that task as a central and absolute condition of our full sanity, metaphysics establishes that for humans self-embrace necessarily has a cognitive dimension, for our organisms are suffused with cognition. There is no perception, experience, thought or action that is not simultaneously a product of mind. We are material organisms that are both conscious and self-con­scious.

We cannot be integrally human if we do not understand that our conscious/self-con­scious biological organisms are the emergent forms of material energy evolving through time. We are a function of being-here, and everything we are is conditioned by it. Where it goes we go. Its destiny is ours. Every particle of transcendent matter that comprises us has been here at least since the big bang 13.7 billion years ago, and will be-here endlessly. As we embrace what we are in the “now” that only we can understand, we realize that the endlessness that characterizes material existence is ours, for we are THAT. Being-here-now anticipates all the nows that await us. In embracing it ― in understanding that we are home now ― we realize that we will always be home.

[3] Physicist Carlo Rovelli in his 2017 book The Order of Time has a chapter entitled “The End of the Present” (p.38 ff.) in which he makes the extraordinary claim that “Not only is there no single time for different places — there is not even a single time for any particular place.” (p.40)

As far as the first part is concerned he acknowledges on p.43: “The notion of ‘the present’ refers to things that are close to us, not to anything that is far away. Our ‘present’ does not extend throughout the universe. It is like a bubble around us.” That is exactly what is meant by the relativity of time explained in the Aeon article cited above. I agree with it completely. The transcendent materialism that I espouse, in fact, provides a metaphysics that supports and explains it.

However, with regard to the second part of his claim that there is no “present” even locally, I would have to say, frankly, his presentation is incoherent. His “proof” is a set of unconnected statements that have no justification beyond the arbitrary diagrams he himself has created to explain them. One might get the impression that Rovelli is indulging in the trendy pastime of debunking the common intuitions of humankind based on nothing but his status as a “scientist” and feels no responsibility to make himself intelligible.

Rovelli doesn’t even claim to have proven his thesis. He acknowledges that the only solid conclusion he can draw is: “A common present does not exist.” (pp.50, 55) I agree, and I have stated that repeatedly. That our perception of time is relative to its various local iterations is the key take-away in all this. His final words sum it up: “Is not what ‘exists’ precisely what is here ‘in the present’ “? (p.55) If the answer to his question is “yes,” then to insist that “there is no present” would be to declare that there is no existence emerging from moment to moment ― that there is nothing here.
