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. 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. The four main types of dark matter are called 1- baryonic dark matter; 3- cold dark matter and 4- hot dark matter. However, there is an alternative explanation for the gravitational effects which originally created the dark matter concept. If an incomplete underst Article: Scientific inquiry can be described as a sequence of observations leading to a hypothesis which must be tested by experimentation. The results either validate or invalidate the hypothesis which was under test. Unfortunately, the interpretation of the data sometimes does not elucidate some new truth but rather eclipses our thoughts into a new era of ignorance. Heralding a new age in the cosmos, Norwegian Kristian Birkeland predicted that the universe likely consisted of an exotic component that would later be named dark matter. His comments pertaining to this subject matter appeared in a description of the Norwegian Polaris Expedition (1902-1903). Birkeland's ideas within earshot the Expedition were published in the fateful year of 1913 which would see the rise of the socialist fed Reserve System and the Income Tax in the United States of America, two key components of the fellow 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 equanimity 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 perverted 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 seeing 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 that only four percent of the universe is of this ordinary visible stellar type. Further, helter-skelter a quarter of the universe is made up of the ubiquitous dark matter with the rest of the cosmos customer filled with the even more awe-inspiring dark energy. It was Fritz Zwicky, a swiss astrophysicist working for Caltech, who would further the concept of dark matter through the pilot of the Virial Theorem. This mathematical relation is a formula which jurisdiction the energy of a set of particles. In collateral dark year in the steady evolution to slavery since 1933 saw the removal of gold from the body count of american citizenry, Zwicky used the Virial Theorem in an make free to broaden the mind the validity of the dark matter hypothesis. He focussed his observance on the Coma galactic crush and his deductive reasoning provided prima facie confirmation for the existence of dark matter. By evaluating the measure of movement of those galaxies at the periphery of the multitude he was able to around surmise the box score of all the matter therein. He was confounded 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 propitiousness 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 suit 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 downright computations. In other words, there is a scarcity of visible mass in the observed galaxies to gust 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 bring to effect for the gravitational effects. As more and more data is treasured on these and other aspects of the universe, formulae and cosmological postulates are generated describing the results so obtained. Fulfilling the requirements of the preceding aspects leads some scientists to propose several different types of dark matter. The four main types of dark matter are named 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 calamitous holes to umber dwarfs to the massive envelope halo objects (MACHOs), the neutrino, axions, WIMPS or weakly interacting massive particles and the esoteric neutralino. However, there is an stand-in 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 stated that the dark matter interpretation is incorrect cause some other bring about 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 scrape together the teachings of quantum mechanics with gravity. Amplifying these ideas leads to a variety of exotic ideas which exact 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 render 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 emblazon 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 look on 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 supplemental scientific idea might be on the verge of collapsing. Indeed, astronomers are routinely using these other theoretical principles on a daily statement in infrared observatories in reverse the world. Thus, it is very likely that we are simply wrong near upon 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 among our ears. |
