Heralding a new age in the cosmos, Norwegian Kristian Birkeland predicted that the universe likely consisted of an exotic component that would later be called dark matter. His comments about this subject matter appeared in a description of the Norwegian Aurora Polaris Expedition (1902-1903). Birkeland’s ideas about the Expedition were published in the fateful year of 1913 which would see the rise of the socialist Federal Reserve System and the Income Tax in the United States of America, two key components of the communist manifesto. Evolutionary processes were in motion throughout all fields of endeavor. Economics, politics, science and the hearts and minds of men and women were in the balance whilst relativism not truth held sway over the modern imagination. Cosmology would suffer from the same ‘evolutionary’ mindset and Birkeland wrote as much:
“We have assumed that each stellar system in evolutions throws off electric corpuscles into space. It does not seem unreasonable therefore to think that the greater part of the material masses in the universe is found, not in the solar systems or nebulae, but in “empty” space.”
In this fashion, Birkeland predicted that because of the ‘evolutions’ present within the cosmos most of the matter in the universe must be found in ‘empty’ space rather than that which is observable in stellar objects. It is currently believed that only four percent of the universe is of this ordinary visible stellar type. Further, about a quarter of the universe is made up of the ubiquitous dark matter with the rest of the cosmos being filled with the even more bizarre dark energy. It was Fritz Zwicky, a swiss astrophysicist working for Caltech, who would further the concept of dark matter through the aegis of the Virial Theorem.
This mathematical relation is a formula which bounds the energy of a set of particles. In another dark year in the steady evolution to slavery since 1933 saw the removal of gold from the accounts of american citizenry, Zwicky used the Virial Theorem in an attempt to ascertain the validity of the dark matter hypothesis. He focussed his attention on the Coma galactic cluster and his analysis provided prima facie confirmation for the existence of dark matter. By evaluating the amount of movement of those galaxies at the periphery of the cluster he was able to approximately surmise the aggregate of all the matter therein.
He was astonished to learn that this sum total of mass is different from a separately computed estimate. This other value was obtained by analyzing the sum total of galaxies and the brightness of the Coma cluster. Juxtaposing this value with the periphery computation he observed that there was a discrepancy of at a minimum four hundredfold. Since the galaxies were insufficiently massive to cause the computed orbital velocities there must be some other mechanism to explain this phenomena. This conundrum became in the scientific lexicon the missing mass problem. Zwicky had established the need for the existence of an invisible source of mass hitherto unknown which must provide the necessary gravitational effect for the cluster.
Thus, it is a fact of the current state of cosmology that the greatest set of evidence for dark matter comes from this galactic gravitational data. Scientists have even made galactic curves describing the rotational properties of stars versus the distance from the galactic center. When the gravitational data is plotted it can be shown that only a small portion of the observed speeds are explicable by classical computations. In other words, there is a scarcity of visible mass in the observed galaxies to attribute the sum total of gravitational effects to visibly observable stars planets and galaxies. Thus, the simplest way to explain this galactic mystery of insufficient mass is to hypothesize a non-detectable type of mass known as dark matter which can be the cause for the gravitational effects.
As more and more data is collected on these and other aspects of the universe, formulae and cosmological postulates are generated describing the results so obtained. Fulfilling the requirements of the aforementioned aspects leads some scientists to propose several different types of dark matter. The four main types of dark matter are called 1- baryonic dark matter; 2- warm dark matter; 3- cold dark matter and 4- hot dark matter. Dark matter ranges from the known to the predicted, from black holes to brown dwarfs to the massive compact halo objects (MACHOs), the neutrino, axions, WIMPS or weakly interacting massive particles and the esoteric neutralino. However, there is an alternative explanation for the gravitational effects which originally created the dark matter concept.
If an incomplete understanding of gravitation is factored into the picture, then it can be asserted that the dark matter interpretation is incorrect because some other cause is generating these phenomena. Several different contending theories have been developed to describe the observed galactic data. In particular, one of the main competing explanations is given by scalar tensor theories which try to combine the teachings of quantum mechanics with gravity. Amplifying these ideas leads to a variety of exotic ideas which challenge our most fundamental notions of physics and astronomy. Other concepts go even further and have been the subject of interest for astronomers like Dr. Riccardo Scarpa since these allow for a cosmology without the inclusion of the enigmatic dark matter.
Dr. Scarpa works at the European Southern Observatory in Santiago Chile using the Very Large Telescope Array at Paranal. With all of his experience in this field, it is interesting to note some of his most recent comments on the superfluous dark matter:
“Dark matter is the craziest idea we’ve ever had in astronomy. It can appear when you need it, it can do what you like, be distributed in any way you like. It is the fairy tale of astronomy.”
In view of these comments one should ask if another scientific idea might be on the verge of collapsing. Indeed, astronomers are routinely using these other theoretical principles on a daily basis in infrared observatories around the world. Thus, it is very likely that we are simply wrong about all of this dark matter. It is within all probability that the only dark matter that we will ever find is that ignorant dark matter between our ears.
The concept of the invisible ether or ‘aether’ is an old concept dating to the time of the ancient Greeks. They considered the ether as that medium which permeated all of the universe and even believed the ether to be another element. Along with Earth, Wind, Fire and Water Aristotle proposed that the ether should be treated as the fifth element or quintessence; this term which literally means ‘fifth element’ has even survived down to the present day to explain an exotic form of ‘dark energy’ which is crucial in some cosmological models. These ideas spread throughout the world until the advent of a new springtime in scientific thought. The first person in the modern era to conceive of the idea of an underlying ether to support the movement of light waves was seventeenth century dutch scientist Christiaan Huygens.
Many others followed in expressing their opinions on the ether concept. Whilst Isaac Newton disagreed with Huygens wave theory he also wrote about the ‘aethereal medium’ although he expressed his consternation in not knowing what the aether was. Newton later renounced the ether theory because in his mind the infinite stationary ether would interrupt the motions of the enormous masses (the stars and planets) as they moved in space. This rejection was reinforced by some other problematical wave properties which were not explicable at the time; most notably, the production of a double image when light passes through certain translucent materials. This property of matter known as ‘birefringence’ was an important hurdle to be overcome for a proper understanding of the wave nature of light.
Some time later (1720) whilst working on other astronomical issues related to light and the cosmos, English scientist James Bradley made observations in hopes of quantifying a parallax. This effect is an apparent motion of foreground objects in comparison to those in the background. Whilst he was unable to discern this parallax effect he happened to reveal another effect which is prevalent in cosmological observations; this other effect is known as stellar aberration. Bradley was able to easily describe this aberration in terms of Newton’s particle theory of light. However, to do so in light of the wave or undulatory theory was difficult at best since to do so would have required a ‘motionless’ medium; the static nature of this ether concept was of course the property which had originally caused Newton’s denial of the idea.
But Newton’s acolytes would find themselves in a difficult position when it was shown that birefringence could be explained through another interpretation of the nature of light. If light was treated as being in a side to side action or ‘transverse motion’ then birefringence could be attributed to a light wave rather than the particle or corpuscular theory of Newton. This along with the detection of an interference effect for light by Thomas Young in 1801 renewed the ascendancy of the wave theory of light. These findings however carried with them all of the preconceived notions prevalent in the scientific mind. Since it was assumed that waves like water and sound waves required a medium of propagation, it was similarly assumed that light still needed a medium or ether for its waves to be transmitted across the universe.
However, further problems would afflict the ether theory. Because of the unique properties of a transverse wave it became apparent that this hypothetical explanation required the ether to be a solid. In response, Cauchy, Green and Stokes contributed theoretical and mathematical observations to an ‘entrainment’ hypothesis which later came to be known as the ‘ether drag’ concept. But nothing would give more impetus to these ideas than when James Clerk Maxwell’s equations (1870s) required the constancy of the speed of light (c). When the implications of Maxwell’s equations are worked out by physicists, it was understood that as a result of the need for a constant speed of light only one reference frame could meet this requirement under the teachings of Galilean Newtonian relativity. Therefore, scientists expected that there existed a unique absolute reference frame which would comply with this need; as a result, the ether would again be stationary.
As a consequence, by the late nineteenth century the aether was assumed to be an immovable rigid medium. However, earlier previous theories existed as to the nature of the aether. One of the most famous of these is known as the ‘aether drag’ hypothesis. In this concept, the aether is a special environment within which light moves. Also, this aether would be connected to all material objects and would move along with them. Measuring the speed of light in such a system would render a constant velocity for light no matter where one tested for light’s speed. This ‘aether drag’ idea originated in the aftermath of Francois Arago’s experiment which appeared to show the constancy of the speed of light. Arago believed that refractive indexes would change when measured at different times of the day or year as a result of stellar and earthly motion. In spite of his efforts, he did not notice any change in the refractive indexes so measured.
Many other experiments would follow; these were performed in order to find evidence of the aether in its many different abstractions. However the most important of these was conducted by american scientists Michelson and Morley. Their experiment considered another alleged effect of a different aether theory which came to be known as the aether wind. Since the aether permeated the entire universe, the earth would move within the ether as it spun on its axis and moved within the solar system about the sun. This movement of the earth with respect to the aether gave rise rise to the idea that it would be possible to detect an ‘ether wind’ which would be sensed because of the aforementioned movement. Thus, their experiment was essentially an attempt to detect the so-called ether wind. This mysterious zephyr would be nearly impossible to detect because the aether only infinitesimally affected the surrounding material world. Michelson first experimented in 1881 with a primitive version of his interferometer; a mechanism designed to measure the wave like properties of light. He would follow this by combining forces with Morley in the most famous ‘null’ experiment of physics.
In this investigation, Michelson utilized an improved version of his interferometer device. Michelson’s apparatus would help him win the Nobel prize for his optical precision instruments and the investigations carried out with them. His most important study being what became known as the Michelson Morley experiment of 1887. Michelson and Morley used a beam splitter made of a partially transparent mirror and two other mirrors arranged horizontally and vertically from a light source. When a beam of light traveled from a source of coherent light to the half-silvered mirror (the semitransparent mirror) it is transmitted to either of the horizontal or vertical mirrors. When the light returned to the eyepiece of an observer the separately returning light waves would combine destructively or constructively. This phenomenon is known as the interference effect for light. It was hoped that a shifting of the interference fringes from that which was normally predicted would be able to ascertain the existence of the aether wind.
To detect this effect, the Michelson interferometer was prepared in such a manner as to minimize any and all extraneous sources of experimental error. It was located in a lower level of a stone edifice to eliminate heat and oscillatory effects which might comprise the experimental results. Additionally, the interferometer was mounted atop a marble slab that was floated in a basin of mercury. This was so that the apparatus could be moved through a variety of positions with respect to the invisible ether. But despite their many preparations the experiment did not yield the expected fringe patterns. Thus, Michelson and Morley concluded that there was no evidence for the existence of the ether. Others would replicate the experiment in different incarnations which modified the premise of the experiment. Each and every one returning a similar negative result. Modern theorists have taken these results and those of many other experiments as being indicative of the non-existence of the aether. However, even the negative result of Michelson Morley has come in to question as far back as 1933.
In that year, Dayton Miller demonstrated the fact that even though the duo’s experiment had not specifically found the expected range of interference patterns, they had found an interesting little noticed effect. Miller then went on to suggest that Michelson Morley had found an experimental sine wave like set of data that correlated well with the predicted pattern of data. He also described how thermal and directional assumptions inherent in the experimental arrangement may have impacted badly on the fringe interference data. Thus, the test may have been performed in an imperfectly conceived experimental setup and with a built in mathematical bias against the detection of an appropriate outcome. Thus, in the future the aether theory in some form or another may still be sustainable as a foundational theory of physics.
Perhaps it is best to leave with these ideas as expressed in 1920 by Einstein who stated that he believed the ether theory to still be relevant to his ideas on space and time:
“More careful reflection teaches us, however, that the special theory of relativity does not compel us to deny ether. We may assume the existence of an ether”
he continued:
“Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether”
and finally:
“According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.”
A black hole is a region of space with such intense gravity that nothing, not even light, can escape. This is the general understanding of the black hole.
If gravity is still a phenomenon, how can we come to use this statement as if it was a fact? This is misleading. Besides, it is preventing our young thinkers from even to consider exploring the true nature of gravity.
One of the things that irritate me most is, when scientists quote gravity and build up all sorts of formulae and equations around it, when they well know that they have no scientific proof of what gravity really is!
As an authority, the majority of scientists are unwilling to admit that all they really know is what they have acknowledged from their tutors - a centuries-old legacy of scientific beliefs some of which were later proven wrong.
It is no secret to say that scientific research is sometimes corrupted due to conflict of interests or the lure of profits.
Personally, I do not believe that black holes really exist as described in the first paragraph. However, let us assume that they do!
I consider myself as another Faraday.
After many years of intensive study, searching for the secrets of gravity, I arrived to a point where I feel the need to share my theory of this so-called black hole.
According to science, there is more space in an atom than there is matter. So, from where does all the energy come to keep the atom together and active, may I ask?
This is my answer.
The energy comes partly from the electrical field of the planet itself. This electrified field is generated by the planet’s inner core electromagnetism field, which as we know produces the north and south poles.
And, the other part of the energy primarily comes from the planet’s nearest Star. This Star, in turn, radiates myriads of electrified particles that shower on to all the neighboring planets. By means of these electrified particles, the atom gets its energy and stays alive and active.
The Auroras at the North and South Poles are a physical example of these electrified particles.
Our solar system, and in turn our galaxy, works in the same harmony. That is why the planets revolve and hold their orbit around their Star. The planets and their Star attract each other because of these electrified forces.
This is what gravity is all about.
The same could be said of one galaxy to another that holds our universe together.
My theory stands that a black hole is nothing more than a space in the universe where the electrified energy of the neighboring Stars do not reach - and therefore an atom cannot survive!
