A Compendious Summary and Chronology of the Aether Theories (rev 2012-03)
Conrad Ranzan
In 1887 two American physicists, Michelson and Morley, performed what has turned out to be one of the most historic but misunderstood experiments in physics.[1]
It must be emphasized that absolute motion [and therefore absolute space] is not inconsistent with the various well-established relativistic effects; indeed the evidence is that absolute motion is the cause of these relativistic effects, a proposal that goes back to Lorentz in the 19th century. —Reginald T. Cahill[2]
Abstract: This article presents the historic development of the aether theory from a scientific (rather than a philosophical) perspective. In step-by-step table format, one may follow the chronology of the exploration of various theories of the medium of the universe —the medium, sometimes equated with absolute space. One may follow the twists, turns and detours —the unexpected experimental results, the new theoretical insights, the unfortunate misinterpretations— of one of the most compelling concepts in modern physics. ... The highlight of the theory development came in the pivotal year of 2002 with the introduction of two testable models based on luminiferous AND gravitational aether: One of these employs a dynamic aether as the first luminiferous-and-gravitational aether in the context of the expanding universe model. The other employs the dynamic aether as the first luminiferous-and-gravitational aether in the context of the non-expanding cellular-universe model. In both theories, it is the presence of aether that causes actual relativistic effects.

6 The Aether of the New Cosmology
Aether is the basic substratum of all space; aether is the raw essence of the Universe. Aether permeates the innermost recesses of all matter. Without it the universe is contrary to nature, contrary to reason and common sense. Without it the universe is utterly absurd.
And what is worrying is that the scholars who have meticulously assembled our complex picture of the universe know it is absurd.
Consider this: The cosmology that is studied in universities the world over, and practiced in the relevant research departments, is a cosmology devoid of the concept of aether. Assumed to be a dispensable relic of 19th century voodoo science, the aether was discarded a long time ago. And the resulting universe model, missing a vital ingredient, has not worked properly since. In fact, as a depiction of reality the class of expanding universe models —of which the various big bang (BB) models are a subset— has been an utter and complete failure.
Sean M. Carroll, a physicist at the California Institute of Technology, sums up one of his extensively researched and densely referenced papers on The Cosmological Constant[3] with the conclusion (which he bases on the no-aether interpretation of the evidence ‘showing’ that the cosmological constant, Λ, dominates the universe, that the expansion of the universe is accelerating, and that the majority of the matter content in the universe must be in an unknown non-baryonic form): “Nobody would have guessed that we live in such a universe. ... This scenario staggers under the burden of its unnaturalness, ...”
In fact, and in bold print, he calls it “the preposterous universe.”
As I understand it, a universe that is “preposterous” is (and my Webster Dictionary will back me up) a universe that is "contrary to nature, reason, or common sense; utterly foolish; absurd." Undoubtedly this is the meaning that the professor intended.
One must realize that Sean Carroll[4] is not some rebellious radical trying to overthrow the expanding universe paradigm, or trying to reinstate the aether. No. As a practicing physicist/cosmologist and a recognized authority on the expanding universe, he is steadfastly committed to resolving the absurdity without venturing outside the BB box, so to speak. In Carroll’s view "... a major challenge to cosmologists and physicists in the years to come will be to understand whether these apparently distasteful aspects of our universe are simply surprising coincidences, ...[whose] underlying structure we do not as yet comprehend."
Unfortunately he is like many others who, for whatever the reason, are unwilling or unable to examine plausible solutions outside of BB cosmology.
What one must realize is that BB cosmology as a plausible theory has two towering handicaps. First, it embraces the unscientific concept of the expansion-of-the-whole-universe. This is blatantly unscientific because it involves an unnecessary extrapolation of a perfectly valid regional phenomenon called space expansion (regardless of how space is defined). Second, it is based on an incomplete theory of gravity, Einstein’s general relativity, which implicitly denies the existence of aether-space.
Aether is the ingredient without which these two handicaps cannot be overcome while maintaining that all-important connection with physical reality. Aether is the ingredient without which the picture of our Universe is quite unnatural and simply preposterous.
The history of conventional cosmology, as the science striving to model the real world, is a revelation of failure; and, after more than a century of Ptolemaic tinkering Academic Cosmology has managed to construct “the preposterous universe.” The cosmology practiced by modern Academia may be said to have originated in 1905 with Einstein’s theory of relativity. In that year, by one of the giants of physics, the foundation was laid; and the fateful error-of-omission was rooted. Einstein’s highly influential theory of motion, space and energy was the first theory that embraced the popular misinterpretation of the Michelson and Morley experiment of 1887. In 1905 Einstein incorporated an implied rejection of luminiferous aether. Although there is nothing in the theory explicitly denying its existence, the authoritative message was that aether is superfluous and unnecessary.
When it came time to construct the first scientific model of the Universe, the task naturally involved Einstein, who by 1916 had formulated general relativity, a new theory of gravity. As one would expect, general relativity, being a purely geometric model of space and time, also denied the existence of aether (thereby maintaining consistency with special relativity). Hence, Einstein’s general-relativity universe-model of 1917 and all his subsequent cosmology models contained the implicit aether denial. Furthermore, since almost all 20th century universe models are based on general-relativity, they compliantly deny aether as well.
The vast majority of journal publishers participate in the denial. Any theory or model that dares to incorporate the aether concept will simply not be accepted for mainstream publication.
There are some serious problems associated with aether denial. The problems are several and multi-layered. I will deal with these later and shed further light on how 20th century scientific cosmology got it so terribly wrong. But first I will detail the historic development of the aether theory.
Aether was needed for several reasons: (1) Philosophically it has always been difficult to define absolute and total nothingness. Aristotle rejected the notion; in his worldview there was no void or vacuum. Descartes considered “it contrary to reason to say that there is a vacuum or space in which there is absolutely nothing.” [5] (2) During the Scientific age there arose the demand for a suitable medium for the propagation of light. In this capacity it was called the luminiferous aether. Isaac Newton, Christian Huygens, and Thomas Young were the early developers of this idea. (3) With Faraday’s discovery of lines of electrical and magnetic force the need for some conducting medium was glaringly obvious. (Remember those lines of force magically revealed by a sprinkling of iron filings?) Faraday’s abstract field concept could be more meaningful if there was some appropriate medium to fill it. (4) Then, with Clerk Maxwell’s electric and magnetic wave theory there again was a need for a propagating medium. A more inclusive luminiferous aether was called for. Aether was enlisted to serve for the propagation needs of all electromagnetic waves.
And there were further reasons.
(5) Aether provided the perfect explanation for the phenomenon called stellar aberration which had been discovered by the English astronomer James Bradley early in the 18th century. The aberration of starlight is the apparent angular displacement of a star in the direction of motion of the observer. Because of the motion of the Earth around the Sun at a speed of about 30 km/second, an observer will see a star not in its true position but in an apparent position. An explanation of the effect is consistent with the motion of Earth through ‘stationary’ aether.
(6) There was (and still is) a need to establish a frame of reference for the measurement of what is termed absolute motion. Referencing relative motion, of course, was not a problem; the details (at least for classical speeds) had been worked out by Galileo. With his equations, one could relate the velocity of an object to any arbitrarily chosen frame of reference (stationary or moving). However, what if one wanted to determine the motion of something, not with respect to another object or frame, but rather with respect to space itself? In other words, take away the “relative” aspect and try to define some sort of fundamental meaning of motion. If space is truly and totally empty, then there is a problem. Then there would be no way to reference absolute motion —no way to answer the question, absolute motion with respect to what? Clearly, something more than “space” was needed. And for 19th-century physicists like Augustin Fresnel, Albert Michelson and Edward Morley, and others, aether was just the thing. Aether could give motion its deeper meaning. The frame “attached” to a proposed aether, and motionless with respect to it, could serve as a preferred frame of reference. Absolute speed then acquires meaning —absolute speed with respect to aether-space (not with respect to the observer).
The motivation for such a reference was extremely important and should not be underestimated. “Without such a reference ... the very idea of motion becomes vague, and all of the nineteenth century development of physics becomes shaky.” [6] By mid-nineteenth century it became clear that no material object in the universe represented a state of absolute rest and that absolute motion could not therefore be measured relative to any material object.[7] It was not merely a hypothetical issue. The need for some kind of absolute reference was real; after all, physicists were incorporating into their theories and equations a kind of motion that was inexplicably invariant. The speed of light —the speed of photon particles or EM waves— is absolute. Undeniably so. Its absolute value is about 300,000 km/second; but absolute (or invariant) with respect to what? The observer is irrelevant; with or without the observer, the speed has a fixed value. Why?
The contemporary way of expressing the historic question goes like this. If all motion is relative, as Einstein’s special relativity theory claims, then how is it possible to enforce Nature’s absolute speed-limit. Her strict speed-of-light barrier is imposed on all entities (entities of all scales). In a rational world an absolute limit needs absolute motion to which it can be applied. Clearly, the motivation for invoking aether-space resides not only in the historic past.
(7) Both Newton’s “spooky” action at a distance and Einstein’s curvature magic were unacceptable as causal explanations of gravity. Aether was needed to (somehow) convey the gravitational force or effect. René Descartes and Christian Huygens invoked a swirling aether-fluid to convey gravitation. Newton suggested that there may be variations of some sort in an all-pervading aether. Then jumping to the 21st century: Reginald Cahill explains gravity as a self-dissipating (contractile) process of aether-space. And DSSU theory (the theory of the Dynamic Steady State Universe) explains unified gravity (Lambda and normal gravity) as a dual-dynamic process of aether.
(8) Undoubtedly, the most powerful motivator was the experimental results that demanded the existence of aether. The repeated detection of absolute motion —of Earth’s absolute motion through space— provided the vital evidence of a preferred frame-of-reference, which is simply the frame in which the aether is at rest. Beginning with the famous experiment of 1887 and then in at least six other documented experiments, the evidence was found. As we saw earlier, the concept of absolute motion is inseparable from the concept of aether. Thus, if you find evidence of the former then your theory must include the latter.
The notion of a universal medium permeating all space has undergone many vicissitudes and spawned even more variants.
The posited substance called aether has changed considerably over the time period covered by the Table. Sometimes the change was radical. It is a pattern that the history of science has witnessed before. For instance, the electron posited by J. J. Thompson differs radically from the electron defined by Schrödinger’s wave equation, which in turn differs just as radically from the electron defined by Dirac’s relativistic theory of the electron. In the same spirit the static aether of Huygens and Maxwell differs radically from the mono-dynamic aether of Augustin Cauchy which in turn differs radically from the dual-dynamic aether of DSSU theory. Electron or aether, when posited under a more advanced theory was able to explain more phenomena.
Professor Sean Carroll is a proponent of the General-Relativity expanding-universe —even though he finds it to be staggeringly unnatural.

Notes: Historically there are three basic types of aether: (i) Aristotle’s fifth element, (ii) luminiferous, and (iii) gravitational. The symbol Λ stands for the cosmological constant in most conventional theories, and for the generic expansion of space in DSSU theory.
The denial of aether has led to a chain of misconceptions of the nature of reality that can only be described as incomplete at best and paradoxical at worst. After the initial misinterpretation of 1887, one misconception led to another, widening the non-reality, deepening the unresolvability. The first misconception was the no-preferred-frame idea. It led to Maxwell’s perfectly valid preferred frame of reference being discarded. Then, without a special frame, there can be no absolute motion. It then follows that without absolute motion ALL translational motion must be relative. And if all motion is relative, what better way is there for describing the physical world than with Einstein’s special and general relativity? The historic chain of misconceptions continued as relativity theory was applied to the whole universe and eventually gave us Sean Carroll’s preposterous expanding universe. Physicists know, or suspect, there is something wrong here. The incompleteness and the paradoxes that have arisen are too easily demonstrated to be ignored.
Unfortunately, the premise was invalid from the very start. Unfortunately, the rejection of aether and the consequential incomplete theory of gravity has led theorists to propose highly speculative universes of mathematical genre —abstractions devoid of reality.
Although the premise was flawed, in the course of theoretical development the step by step logic, decade after decade, was wonderfully flawless and found its grandest expression as the golden age of the expanding universes. The 20th century witnessed an astrocopeia of models based on Einstein’s gravity equations. (Check out the lengthy list of expansion models in Table 2 of the Web article, Models of the Universe). Like the Sorcerer’s Apprentice whose spell conjured up too many magic brooms, theorists were finding that their magical mathematical equations were producing more and more versions of the expansion scenario.
As I said, it was a golden season; expansion was the big thing, and the harvest was abundant. But now it is wintertime —time for testing survivability. This vast enterprise, responsible for proliferating and for stockpiling a multitude of theoretical models, must now face the frigid fact that there was —there IS— only one real universe! ... And any scientist, professional or amateur, will tell you that a theory that allows (or predicts) too many possibilities makes for a very weak theory. A weak theory is more appropriately called a hypothesis or a speculation; and rarely survives.
The point is they —Academic Cosmologists— have problems. Serious problems.
When theorists deny the existence of aether they are left with no medium for the propagation of Maxwell’s electromagnetic waves.
Seemingly unaware of the inconsistency, physicists discard the perfectly intuitive and sound notion, whereby aether serves as the medium for the propagation of light, while claiming that the emptiness of space is filled with all kinds of stuff like quantum particle-pair formation, and various entities continually popping in and out of existence, and, of course, vacuum energy. But note, these things are not just scattered around randomly in “empty” space. They permeate all space. Physicist Robert Oerter, in his book A Theory of Almost Everything, explains that there are harmonic oscillators, one at each point in space, wherever there are quantum fields (which happens to be most everywhere). In what is otherwise empty space, these oscillators are pulsating in their lowest energy state. “We know, however, that a harmonic oscillator has some energy even in its lowest energy state. This vacuum energy exists at every point in space ...” [27] Robert Oerter leaves no room for doubt; there are entities at every point in space!
But wait a minute ... that sounds suspiciously like a space medium.
Let’s shine a light into this space used by “the standard model of modern physics.” A light beam travels through points in (or of) space; there are oscillators at every point; the light, then, must pass through the oscillators. The light can’t go around the oscillators since there are no gaps, no free points, no free zone. Clearly, light is being conducted —conducted by the oscillators along the light ray’s path —by the space medium itself —by the luminiferous aether that physicist have long rejected. What other conclusion could there possibly be? ... Light does travel through a ubiquitous space-medium. Yet almost no physicist acknowledges the fact. (Let there be no doubt about the seriousness of aether denial or aetherphobia. Those afflicted, as if participating in a reversal of a popular fable in which the Emperor IS fully clothed, are claiming He has no clothes!)
The situation with the light-conducting-medium reveals a problem on another level. It reveals the age old “problem” of heresy, the undermining of the establishment’s sacred ideas. The guardians of the Official view do not tolerate dissent. Consequently, under the oppressive rules of Academia no one today dares to call it the luminiferous aether let alone generic aether. For two thousand years, few dared to challenge the authority of Aristotle. Today, few dare to challenge the authority of Einstein.
Aether denial, of course, goes hand in hand with the denial of absolute motion —yet absolute motion is surprisingly easy to prove.
The denial of aether led Einstein to two famous but incomplete theories of relativity. One is missing the principle of absolute motion and, therefore, is unable to explain the real difference in the speed of a light ray (along separate paths) observable in any gas-mode Michelson apparatus (particularly when calibrated as per Cahill’s method to correct for Lorentzian contraction). The other theory is missing ... How shall I state this? ...
Here we have what may well be the biggest problem of all. Without aether there is no plausible way to convey the effect of gravity. We are left with no way to convey Newton’s force of gravity. And in the terminology of general relativity: we are left with no way to manifest the effect of space curvature.
It is sad to note that more than 300 years after Newton presented the world with a scientific definition of gravity, the cause is still being reported as a mystery. Peter Bergmann, a devoted student and follower of Einstein, underscores this dismal deficiency by authoring a book entitled The Riddle of Gravitation. The title refers to the unresolved problem of Einstein’s theory of gravity. For relativity experts like Bergmann, gravity is a mystery for the simple reason that the underlying mechanism is missing. The rejection of aether, and its dynamic properties, is directly responsible for this impasse.
Without aether, theorists are led to a totally unrealistic picture of the universe. They arrive at a philosophically untenable picture of an expanding universe with its physically impossible singularity initial state and its questionable end state. They lose sight of the principle that the Universe is the manifestation of existence; and existence does not begin or end; existence is absolute and cannot be qualified in any way.
There is also a major practical problem. Without aether there is no plausible way to explain the abundant experimental evidence detailed in the Chronology Table above. There is no way to explain the findings by using standard physics. Yet it appears that official institutions are not in any hurry to solve the mystery. For instance, in 1999 NASA set up an investigative commission headed by Dr. David Noever (a NASA scientist) to review the Maurice Allais experiments. A decade later and we’re still waiting on the outcome. The lengthy delay speaks volumes. One suspects there is a desperate effort to avert a revolution in physics and cosmology; and it is unlikely that the report will ever be issued. Maurice Allais is unlikely to live long enough to see it anyway. A website search of NASA (http://Science.msfc.nasa.gov/) gives only the original 1999 report.[28] [29] Two more examples of neglected experiments with solid evidence are the Dayton Miller 1925/26 studies and the Roland De Witte 1991 tests lasting 178 days. It has been predicted that these two experiments will eventually be recognized as two of the most significant experiments in physics. The experiments were completely independent and used significantly different techniques yet they detected the same velocity of absolute motion. Furthermore, they detected clear evidence of turbulence in the flow of aether past the Earth. They had discovered aether-type gravitational waves. Again, officially sanctioned theories have no plausible explanation.
Both Miller and De Witte have been repeatedly attacked for their discoveries. Sadly, De Witte was never permitted to publish his data in a physics journal. Tragically, after being dismissed from his research position, being misled by so-called anti-relativists, and having his findings ignored and even censured, Roland De Witte became deeply depressed and suffered an early death.
The rejection of aether has now led to a near crisis situation in Cosmology and Physics. The proof of the existence of aether is out there. It is being ignored and even suppressed.[30] Evidence is ignored, year after year. All the while the experimental physicists keep rediscovering what is not supposed to exist —the aether and its associated absolute motion. The most recent rediscovery occurred in 2006. (See the Chronology Table). It involved a new method —method number three, if your keeping count.
A review of the history of aether reveals that aether is repeatedly being re-discovered; as if its previous discovery has been forgotten, again and again. For instance, Roland De Witte was unaware of Miller’s historic work. ... Forgive the broadness of my question, but what is going on here!? What kind of science is being practiced in society’s noble institutions when solid experimental evidence is ignored? Or worse, censored and suppressed?
While there is mostly silence among the ranks of institutionalized degree holders, this fact remains: Without aether we are unnecessarily burdening ourselves with an incomprehensible “preposterous universe.”
The study and research of a cosmos devoid of its essential ingredient, aether, is as pointless and unproductive as were traditional theological dissertations. Cosmology without the aether concept is a dead-end endeavor —assuming, of course, that one’s goal is the perception of reality.
Cosmology as a belief system is a different matter. Needless to say, if one is practicing cosmology as a quasi-religion then one is free to believe whatever one chooses. Unrestrained by the scientific method, one is free to ignore the paradoxes that arise, free to include the non sequiturs, free to worship any authority. It is indeed sad to report that Academic Cosmology has made a grave digression; it has become a belief system. The aether controversy reveals the century long transformation of Academic Cosmology —a transformation into non-scientific Creationism.[31] Science historian Corey S. Powell in his book, God in the Equation, provocatively and eloquently argues that what Academia practices today is a faith called “science/religion” and details how Einstein, the most popular genius of the century, became the prophet of a cosmological revolution.
The faith-based cosmology dominated the 20th century. The new cosmology began in the year 2002 with Cahill’s discovery of the mechanism of gravitation and the author’s development of DSSU theory. It is a cosmology based on a new concept of aether.
It should be made clear that the new aether theory with its heretical notion of absolute space and absolute motion does not necessarily entail the rejecting and replacing of existing theories. For instance, Einstein’s theory of relative motion remains valid in a restricted sense; the theory is subsumed as relative motion becomes but a special case of a more general theory of absolute motion. General relativity theory remains valid in a restricted mathematical sense.
Now if the subsummation of Einstein’s relativity is what is involved here, then most physicists have misconceived the threat to their belief system. They had always thought that legitimizing an aether theory would mean the overthrow of “relativity.” They simply had not expected that a theory of absoluteness could embrace “relativity” and incorporate it into a broader theory.
Another misconception is the notion that absolute space is explicitly a static space. True enough, Newton’s space was absolute and static. But it is not a necessary combination. Consider a non-absolute space. Einstein’s geometrized space was non-absolute and notably dynamic. And this also is not a necessary combination. These characteristics are but the chosen axioms of a particular theory. Newton chose absolute and static, Einstein chose non-absolute and dynamic. Both choices are problematic. So the obvious question arises; what about a combination of absolute and dynamic? And the answer came in the year 2002. Under a new theory (see DSSU theory in the table above) axioms were selected to make space absolute and dynamic. Absolute because the experimental evidence demands it to be so; dynamic because Einstein and Friedmann proved it to be so. Significantly, in DSSU theory, space, as general relativity unequivocally demands, retains its ability to expand and to contract. Definitively, DSSU aether-space is both absolute and dual-dynamic and not at all static.
This is a totally new concept of aether. (R.T. Cahill’s Process-Physics aether also deserves this claim.)
Does this make for a superior type of space? To answer this question, consider what the standard theory is missing and what the new-cosmology theory offers. Both Newton’s gravity and Einstein’s gravity do not give an actual cause or an actual mechanism; but a properly constructed aether theory does. The dual-dynamic aether provides Einstein’s mathematical theory of gravity with what the theory has long been lacking —a real-world ‘substance’ with the real ability to convey the gravitational effect. (And this ability has nothing to do with the propagation of gravitons. The new aether is not a medium for gravitons.) In other words, DSSU aether endows the theory of gravity with its essential causal mechanism.
The definition of the phenomenon we know as gravity (applicable to DSSU theory as well as Process Physics) is the inhomogeneous bulk flow of aether-space towards and into matter. The emphasis is on the inhomogeneity of the aether flow, rather than the flow-motion itself, and manifests as an acceleration. The foregoing is the definition of normal gravity (i.e., contractile) the related definition for unified gravity simply includes the expansionary aspect of aether-space.
Indeed, the New Cosmology does have a superior type of space. Not only does it provide the causal mechanism for gravity, but it also makes possible a unified theory of gravity.
The aether theorists and researchers of today clearly have the advantage. The case for the existence of aether need not at all be defended —since the experimental evidence is undeniable. It is those who actively deny the experimental evidence or passively ignore the historical and continuing research who are exposing themselves to accusations of scientific malpractice. ... It is they who are responsible for fabricating “the preposterous universe.”
