Are theories judged on the basis of empirical tests of their predictions, as proposed by Karl Popper and others, or are new theories adopted by younger scientists while old theories fade away when their advocates die, as Max Planck suggested? A famous historical episode, the rejection of steady state cosmology and the revival of the big bang cosmology following the 1965 discovery of the cosmic microwave background radiation, is examined to determine whether the scientific community followed Popper’s (...) or Planck’s principle. It is found that by 1975 almost all supporters of the steady state had either switched to the big bang or stopped publishing on cosmology. This case therefore seems to exemplify Popper’s principle, although it should be noted that two of the founders of steady state cosmology had strongly proclaimed their adherence to that principle. The case does not support the Popperian claim that successful novel predictions provide better evidence for a theory than deductions of known facts. (shrink)

The existence of big bang relic neutrinos—exact analogues of the big bang relic photons comprising the cosmic microwave background radiation—is a basic prediction of standard cosmology. The standard big bang theory predicts the existence of 1087 neutrinos per flavour in the visible universe. This is an enormous abundance unrivalled by any other known form of matter, falling second only to the cosmic microwave background (CMB) photon. Yet, unlike the CMB photon which boasts its first (serendipitous) (...) detection in the 1960s and which has since been observed and its properties measured to a high degree of accuracy in a series of airborne/satellite and ground based experiments, the relic neutrino continues to be elusive in the laboratory. The chief reason for this is of course the feebleness of the weak interaction. At present, the observational evidence for their existence rests entirely on cosmological measurements, such as the light elemental abundances, anisotropies in the cosmic microwave background, and the large-scale matter power spectrum. In this paper we argue that Direct Detection of relic neutrino background is indeed impossible by any means, because of two chief reasons: (a) there was no such thing of cosmic singularity, hence the hot big bang/primeval atom model was based on false premises (quantum birth assumption); (b) the neutrino existence itself is not unquestionable, in particular if we consider a realism view of vector potential, A, in classical electrodynamics.

We analyse aspects of the Big Bang program in modern cosmology, with special focus on the strategies employed by its adherents both in defending the theory against anomalous data and in dismissing rival accounts. We illustrate this by critically examining four aspects of Big Bang cosmology: the interpretation of the cosmic red-shift, the explanation of the cosmic background radiation, the inflation hypothesis and the search for dark matter. We conclude that the Big Bang's dominance of contemporary (...) cosmology is not justified by the degree of experimental support it receives relative to rival theories. (shrink)

Proponents of Bayesian confirmation theory believe that they have the solution to a significant, recalcitrant problem in philosophy of science. It is the identification of the logic that governs evidence and its inductive bearing in science. That is the logic that lets us say that our catalog of planetary observations strongly confirms Copernicus’ heliocentric hypothesis; or that the fossil record is good evidence for the theory of evolution; or that the 3oK cosmic background radiation supports big bang (...) cosmology. The definitive solution to this problem would be a significant achievement. The problem is of central importance to philosophy of science, for, in the end, what distinguishes science from myth making is that we have good evidence for the content of science, or at least of mature sciences, whereas myths are evidentially ungrounded fictions. The core ideas shared by all versions of Bayesian confirmation theory are, at a good first approximation, that a scientist’s beliefs are or should conform to a probability measure; and that the incorporation of new evidence is through conditionalization using Bayes’ theorem. While the burden of this chapter will be to inventory why critics believe this theory may not be the solution after all, it is worthwhile first to summarize here the most appealing virtues of this simple account. There are three. First, the theory reduces the often nebulous notion of a logic of.. (shrink)

This paper reviews the origin of inertia according to Mach's principle and Weber's law of gravitation. The resulting theory is based on simultaneous nonlocal gravitational interactions between particles in the solar system and others in the remote universe beyond the Milky Way galaxy. It explains the precession of the perihelion of Mercury. A most important implication of the Mach-Weber theory of the force of inertia is the necessity for a large amount of uniformly distributed matter in the galactic universe. This (...) matter could be the source of the cosmic background radiation. Nonlocal inertia forces are compatible with a static universe and also with an expanding universe but the latter would demand slow changes in the mass of particles and the gravitational constant.

The relation of the special and the general principle of relativity to the principle of covariance, the principle of equivalence and Mach's principle, is discussed. In particular, the connection between Lorentz covariance and the special principle of relativity is illustrated by giving Lorentz covariant formulations of laws that violate the special principle of relativity: Ohm's law and what we call “Aristotle's first and second laws.” An “Aristotelian” universe in which all motion is relative to “absolute space” is considered. The first (...) law: a free particle is at rest. The second law: force is proportional to velocity. Ohm's law: the current density is proportional to the electrical field strength. Neither of these laws fulfills the principle of relativity. The examples illustrate, in the context of Lorentz covariance and special relativity, Kretschmann's critique of founding Einstein's general principle of relativity on the principle of general covariance. A modification of the principle of covariance is suggested, which may serve as a restricted criterium for a physical law to satisfy Einstein's general principle of relativity. Other objections that have been raised to the validity of Einstein's general principle of relativity are based upon the preferred state of inertial frames in the general, as well as in the special theory, the existence of tidal effects in “true” gravitational fields, doubts as to the validity of Mach's principle, whether electromagnetic phenomena obey the principle, and, finally, the anisotropy of the cosmic background radiation. These objections are reviewed and discussed. (shrink)

I'm Professor of Physics at the University of Washington in Seattle . I do basic research in ultra-relativistic heavy ion physics with the STAR experiment, using the RHIC facility at Brookhaven National Laboratory, colliding gold nuclei to produce systems that look something like the first microsecond of the Big Bang. I do not work much in cosmology and astrophysics, although I've published a paper or two in those areas, but I do write a bi-monthly science column for Analog Science Fiction/Fact (...) Magazine . One of my columns was entitled BOOMERanG and the Sound of the Big Bang " and was published in the January-2001 issue of Analog. It described the then-recent Antarctic balloon flight that mapped the small-angle temperature variations of the cosmic background radiation. Following the lead of the scientists involved in the project, I described the temperature variations they observed as, in effect, a recording of the "sound of the Big Bang" when the universe was 376 thousand years old.

Astronomical observations of redshifts and the cosmic background radiation show that there is a local frame of reference relative to which the solar system has a well-defined velocity. Also, in cosmology the cosmological principle implies the existence of cosmic time and unique local reference frames at all spacetime points. On the other hand, in a fundamental postulate, the theory of special relativity excludes the possibility of the velocity of the Earth from entering into theories of local (...) physics.The theory put forward in this paper resolves this conflict between local physics and cosmology. The theory retains the essential ingredient of the mathematical structure of special relativity, namely covariance under the Lorentz symmetry group, but changes radically the interpretation of the physical significance of the Lorentz transformation. The theory is based on the postulate that in free space the fundamental interactions in physics are propagated with constant velocity with respect to the local rest frame. In Minkowski spacetime the local rest frame of reference defines a unique time axis and consequently a unique three-dimensional spatial hyperplane. One particularly important result of this is that the theory includes the classical notion of simultaneity. From the fundamental postulate it follows that the equations of local physics, when expressed in terms of the rest frame coordinate system, must be covariant under the Lorentz symmetry group. By the identification of the local rest frame with the (unique) cosmological local reference frame the two theories become mutually consistent.The effects of the motion of the Earth on laboratory experiments are discussed. It is pointed out that existing experimental data do not discriminate between the present theory and that of special relativity: a proposal for an experimental test is made. (shrink)

Quantum theories constructed on the noncommutative spacetime called the Groenewold–Moyal plane exhibit many interesting properties such as Lorentz and CPT noninvariance, causality violation and twisted statistics. We show that such violations lead to many striking features that may be tested experimentally. These theories predict Pauli forbidden transitions due to twisted statistics, anisotropies in the cosmic microwave background radiation due to correlations of observables in spacelike regions and Lorentz and CPT violations in scattering amplitudes.

In 1965, the discovery of a new type of uniform radiation, located between radiowaves and infrared light, was accidental. Known today as Cosmic Microwave background, this diffuse radiation is commonly interpreted as a fossil light released in an early hot and dense universe and constitutes today the main ’pilar’ of the big bang cosmology. Considerable efforts have been devoted to derive fundamental cosmological parameters from the characteristics of this radiation that led to a surprising universe (...) that is shaped by at least three major unknown components: inflation, dark matter and dark energy. This is an important weakness of the present consensus cosmological model that justifies raising several questions on the CMB interpretation. Can we consider its cosmological nature as undisputable? Do other possible interpretations exist in the context of other cosmological theories or simply as a result of other physical mechanisms that could account for it? In an effort to questioning the validity of scientific hypotheses and the under-determination of theories compared to observations, we examine here the difficulties that still exist on the interpretation of this diffuse radiation and explore other proposed tracks to explain its origin. We discuss previous historical concepts of diffuse radiation before and after the CMB discovery and underline the limit of our present understanding. (shrink)

Due to the historical origin and development of reason, an inventory of its main concepts at a particular moment is less interesting to us than the study of their formation and fixation. This process is studied here in the light of examples from the history of physics. The first one concerns the subsumption of the well-known phenomena of free fall and planetary motion to a new concept of gravity in the 17th century; the remaining examples, drawn from 19th century electrodynamics (...) and 20th century microphysics and cosmology, display the interplay of such concepts with empirical novelties that prompt them in some case and realize them in others.

Cosmology as Weltanschauung is as old as the world. Cosmology as a physical discipline, however, is a child of this century, born in 1917, when Albert Einstein and Willem de Sitter first applied the theory of general relativity to the space-time of the entire universe. When did the child come of age and become a fully-fledged science? A popular myth shared by many practitioners holds that this did not happen until 1965, when the discovery of the 2.7K cosmic microwave (...) background radiation validated the concept of the hot big bang. Earlier accomplishments culminating in the 1965 event include the derivation of evolving relativistic models by Alexander Friedmann and George Lemaître, Edwin Hubble’s discovery of the redshift-magnitude relationship and George Gamow’s theory of the primordial nucleosynthesis containing the prediction of the microwave background left from the hot and dense past of the universe. This linear development is thrown into sharper relief in textbooks, by referring to an inarticulate.. (shrink)

The uncertainty on measurements, given by the Heisenberg principle, is a quantum concept usually not taken into account in General Relativity. From a cosmological point of view, several authors wonder how such a principle can be reconciled with the Big Bang singularity, but, generally, not whether it may affect the reliability of cosmological measurements. In this letter, we express the Compton mass as a function of the cosmological redshift. The cosmological application of the indetermination principle unveils the differences of the (...) Hubble-Lemaître constant value, $$H_0$$, as measured from the Cepheids estimates and from the Cosmic Microwave Background radiation constraints. In conclusion, the $$H_0$$ tension could be related to the effect of indetermination derived in comparing a kinematic with a dynamic measurement. (shrink)

The main foundations of the standard \CDM model of cosmology are that: the redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; the cosmic microwave background radiation and its anisotropies derive from the high energy primordial Universe when matter and radiation became decoupled; the abundance pattern of the light elements is explained in terms of primordial nucleosynthesis; and the formation and evolution of galaxies can be explained only in terms of (...) gravitation within a inflation + dark matter + dark energy scenario. Numerous tests have been carried out on these ideas and, although the standard model works pretty well in fitting many observations, there are also many data that present apparent caveats to be understood with it. In this paper, I offer a review of these tests and problems, as well as some examples of alternative models. (shrink)

The message is that physics has an „outward bound” of scientific inquiry in the field of cosmology. I present it in the historical development. Physics and astronomy, developing since the seventeenth century, inherited from the early Greek philosophers the conception that the Universe as a whole is invariable. In nineteenth century this conception in conjunction with the conception of eternity of the Universe gave rise to contradictions with other laws of physics indicating that cosmology is not a branch of physics (...) since the notion of the Universe is not a physical one. Cosmology returned to physics as its important branch due to the advent of general relativity theory and the discovery of the cosmic microwave background radiation. Modern cosmology generates fundamental problems creating real limits to inquiries in physics viewed as an empirical science. The very notion of the Universe shows that the scientific method reaches there limits of its applicability. Does „to exist” mean „to be observed by someone”? Should the definition of the Universe be based on a current physical theory, e.g. on Einstein’s general relativity, giving rise to a kind of mathematical instability? Is the fashionable concept of the „multiverse” a physical one or is a purely metaphysical notion in a scientific disguise? If the Universe is unique, is it meaningful to describe it in the framework of physics, which by its method always assumes that the number of objects it describes, is unlimited? Apart from these permanent philosophical problems there are concrete urgent problems generated by cosmology: the nature of dark matter and dark energy. These two species of „substance” appear only in cosmology and do not fit the laboratory physics; contrary to the three centuries long tradition of modern science, now cosmology inspires physics in a troublesome way. A separate class of limits to physics is generated by the theorem in general relativity that the Universe emerged from an initial curvature singularity of the spacetime. At the singularity the whole scientific inquiry breaks down. Cosmology of the very early Universe suggests that in its evolution two specific epochs took place, that of quantum gravity and an inflationary epoch. The underlying them two physical theories are incomplete and seem to be inherently untestable. Furthermore, the experimentally verifiable physics cannot explain the origin of the initial conditions determining properties of the Universe which emerged from the singularity. (shrink)

Ordinary clocks do not measure time in the common and Newtonian sense, and there is a similar problem for spatial measurements due to effects of motion and gravitation. Einstein’s theories of relativity are based on the denial of the possibility of the ‘absolute’ measurements that would be required. Nevertheless, here it is shown how such measurements can be performed. For this purpose, a “light clock” (or equivalent) is linked with a “space-time odometer” that counts the zero crossings in the field (...) of the cosmic microwave background radiation. The readings of these two instruments allow to calculate the time interval and the length of their path in Euclidean space even in the presence of local variations in gravitational potential. (shrink)

According to Einstein, a universal time does not exist. But what if time is different than what we think of it? Cosmic Microvawe Background Radiation was accepted as a reference for a universal clock and a new time concept has been constructed. According to this new concept, time was tackled as two-dimensional having both a wavelength and a frequency. What our clocks measure is actually a derivation of the frequency of time. A relativistic time dilation actually corresponds (...) to an increase in the wavelength of time. At the point where time wavelength and time frequency is equal, where light is positioned, quantum-world and macro- world are seperated. Gravity was redefined with respect to time and the new two dimensional time fabric of the universe was speculated to be the source of dark energy causing the universe to expand. According to this new point of view quantum realm and macro-world can be better understood. This new time concept provide a basis for our understanding of quantum gravity and provide the long-sought answers to well known problems of it. A prediction of the presented theory is that the universe will expand at various rates at different regions due to the fact that particular surroundings will create different gravities and cause a different gravity- time wavelength effect yielding various time delays for calculating this rate of expansion.

Space is one of the most fundamental concepts over which scientific knowledge has been constructed. But it is also true that space concepts extrapolate by far the scientific domain, and permeate many other branches of human knowledge. Those are fascinating aspects that could di per se justify the compilation of a long bibliography. Another one is the passion for books. My interest in some physical, historical and philosophical problems concerning the concept of space in Physics, and its properties, can be (...) traced back to the early 1980. Since that time, I have being studying, with several collaborators, the influence of space dimensionality in different physical phenomena, like the Casimir Effect, neutron diffraction, Cosmic Microwave Background Radiation and the stability of Schrödinger’s and Dirac’s hydrogen atom in arbitrary number of dimensions, as well as epistemological aspects of the works of Kant, Ehrenfest an others on this particular subject. Meanwhile, I gave lectures about the History of the Concepts of Space in Physics at the Centro Brasileiro de Pesquisas Físicas (CBPF), at the Program of History of Sciences, Technics and Epistemology of the Federal University of Rio the Janeiro (UFRJ) and also at the Physics Institute of the State University of Rio de Janeiro (UERJ). As a consequence of both this interest and my love for books, I continuously bought books on space for my personal library which contains now quite one half of all the books quoted here. In 1996, Roberto Moreira and I published the Sources for the History of Space concepts in Physics: From 1845 to 1995 in the series Notas de Física of the CBPF (NF # 084/96), which is still available online. This was a first initiative to share our bibliography on space. At that time, it contained 1075 references, including 414 books entirely devoted to space, 380 articles in periodical journals and proceedings and 281 miscellaneous citations. After fifteen years, I decided to focus my attention here to collect what in my opinion are the 601 essential books which could be useful for anyone interested on learning about space. An important restriction is imposed here by language: only texts written in English, French, German, Italian, Spanish, Portuguese and Latin were considered. References are given in chronological order covering the period between 1739 and 2010. For each year, the books are listed in alphabetical order of authors’ name. An onomastic index is included at the end of the book. -/- Francisco Caruso Rio de Janeiro, October 2011 . (shrink)

Short review of Helge Kragh's excellent book on the contest between big bang and steady state theories of the universe.

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...) of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

The claim of inflationary cosmology to explain certain observable facts, which the Friedmann-Roberston-Walker models of `Big-Bang' cosmology were forced to assume, has already been the subject of significant philosophical analysis. However, the principal empirical claim of inflationary cosmology, that it can predict the scale-invariant power spectrum of density perturbations, as detected in measurements of the cosmic microwave background radiation, has hitherto been taken at face value by philosophers. The purpose of this paper is to expound the theory (...) of density perturbations used by inflationary cosmology, to assess whether inflation really does predict a scale-invariant spectrum, and to identify the assumptions necessary for such a derivation. The first section of the paper explains what a scale invariant power-spectrum is, and the requirements placed on a cosmological theory of such density perturbations. The second section explains and analyses the concept of the Hubble horizon, and its behaviour within an inflationary space-time. The third section expounds the inflationary derivation of scale-invariance, and scrutinises the assumptions within that derivation. The fourth section analyses the explanatory role of `horizon-crossing' within the inflationary scenario. (shrink)

We historically trace various non-conventional explanations for the origin of the cosmic microwave background and discuss their merit, while analyzing the dynamics of their rejection, as well as the relevant physical and methodological reasons for it. It turns out that there have been many such unorthodox interpretations; not only those developed in the context of theories rejecting the relativistic paradigm entirely but also those coming from the camp of original thinkers firmly entrenched in the relativistic milieu. In fact, (...) the orthodox interpretation has only incrementally won out against the alternatives over the course of the three decades of its multi-stage development. While on the whole, none of the alternatives to the hot Big Bang scenario is persuasive today, we discuss the epistemic ramifications of establishing orthodoxy and eliminating alternatives in science, an issue recently discussed by philosophers and historians of science for other areas of physics. Finally, we single out some plausible and possibly fruitful ideas offered by the alternatives. (shrink)

This paper deals with an (otherwise classical) two-(non-interacting) particle system immersed in a common stochastic zero-point radiation field. The treatment is an extension of the one-particle case for which it has been shown that the quantum properties of the particle emerge from its interaction with the background field under stationary and ergodic conditions. In the present case we show that non-classical correlations—describable only in terms of entanglement—arise between the (nearby) particles whenever both of them resonate to a common (...) frequency of the field. For identical particles the entanglement becomes maximum and must be described by totally (anti)symmetric states. (shrink)

This is a response to an article by Wade Allison in which he argues that we should accept drastically higher doses of ionizing radiation than what we currently do. He employs four arguments in defence of his position: comparisons with background radiation, the positive experiences of radiotherapy, the presence of biological defence mechanisms against radiation, and a concession by Swedish authorities that their approach to reindeer meat after the Chernobyl fallout was unnecessarily strict. It is shown (...) that each of the four arguments is fallacious. In conclusion, the traditional weighing of risks against benefits in radiation protection is defended. (shrink)

The cosmic censorship hypothesis states that the general theory of relativity has built in mechanisms to prevent the formation of "naked singularities," pathologies in the spacetime structure that lead to a breakdown in predictability and determinism. This paper discusses some attempts to turn the vague hypothesis into a precise conjecture. Evidence in favor of and against the conjecture is briefly reviewed. Finally the possibility of forming naked singularities via black hole evaporation due to Hawking radiation is discussed.

We construct all cosmic field tensors which are symmetric rank-two tensor concomitants of a metric and a background metric and which have zero divergence when the background metric satisfies the generalized De Donder condition. The resulting background cosmic field represents an Einstein space-time.

In lieu of an abstract, here is a brief excerpt of the content:Fallout from Government-Sponsored Radiation ResearchCarol Mason Spicer (bio)On December 28, 1993, Energy Secretary Hazel R. O'Leary publicly appealed to both the executive and legislative branches of the United States Government to consider compensation for individuals who were harmed by their exposure to ionizing radiation while enrolled in government-sponsored studies conducted between 1940 and the early 1970s.1 The call for compensation was issued three weeks after Secretary O'Leary (...) disclosed that radiation experiments involving humans, sometimes without their consent, had occurred under the auspices of the Atomic Energy Commission (AEC), a forerunner of the Department of Energy (DOE). Secretary O'Leary directed her department to investigate the nature and extent of the experiments, report on their medical and ethical acceptability, and locate the research subjects or their families.Background to the Federal Advisory CommitteeDespite the fact that the existence of many government-sponsored radiation experiments was not a secret—much of the research was reported at the time in scientific journals, and in 1986, Representative Edward J. Markey (D-MA) conducted congressional hearings on such radiation research—Secretary O'Leary's disclosure of the AEC experiments and her call for compensation made the experiments common knowledge and sparked a swift and complex governmental response involving both the executive and legislative branches.It is curious that the "radiation experiments" have garnered so much attention now, since they were virtually ignored in the wake of the 1986 hearings. Secretary O'Leary's disclosure of the radiation studies grew out of a general reassessment of secrecy in government. In April 1993, the Clinton administration set out to review the system of government secrecy that evolved during the Cold War, and in May 1993, DOE began reviewing and declassifying files pertaining to nuclear weapons research. When Dan Reicher, a top aide to Secretary O'Leary, informed her in November of the impending publication of an Albuquerque Tribune investigative report (Welsome 1993) on an experiment conducted between 1945 and 1947 in which 18 subjects were injected with plutonium, [End Page 147] the topic of questionable research involving the exposure of human subjects to radiation was added to the DOE list of information to be disclosed. At the time, it was thought to be but one small part of a massive quantity of DOE information to be made public.As part of its effort to investigate the radiation experiments, DOE established a toll-free telephone hot line for individuals who thought they might have been the subjects of radiation exposure experiments. The hot line, originally staffed by three people to handle the anticipated few dozen calls per day, received more than 2,000 calls in the first week. By early January the hot line was flooded with 6,000 to 10,000 calls daily, and its staff had increased more than ten-fold. Although many of the calls were deemed not to be candidates for further investigation, the extent of the radiation-related experiments, sponsored not only by AEC, but also by the military and other government departments and agencies, took officials by surprise.On December 30, the Department of Defense, the Department of Veterans Affairs, and the National Aeronautics and Space Administration all announced that they were initiating thorough reviews of their files to determine the extent and nature of any radiation experiments conducted under their auspices.2 In January, the CIA and the Department of Health and Human Services, including the National Institutes of Health, followed suit.The White House publicly entered the arena in late December announcing that it would hold a meeting on January 3, 1994, to help coordinate the government's investigative effort. At the same time, Senator Edward M. Kennedy (D-MA) called for a mid-January congressional hearing to investigate experiments conducted between 1946 and 1956 in which mentally retarded boys at the Fernald State School in Massachusetts were fed radioactive iron supplements or milk containing radioactive calcium to enable researchers to trace the absorption of those nutrients. Senator Kennedy's hearing, conducted by the Subcommittee on Health of the Senate Committee on Labor and Human Resources, was the first of a number of congressional hearings held earlier this year to investigate the...

In this chapter, important transcultural and multi-civilizational foundations for a comprehensive philosophy of cosmic life are presented from a systematic and at the same time historical perspective. An “anacrusis” regarding the origin of the philosophical term ‘cosmic life’ is followed by systematic groundwork in relation to Gotthard Günther’s concepts of poly-contexturality and trans-classical science. These are extended and complemented by the views of other thinkers. Against this background, the new term ‘panenbiotism’ (“all-in-life-doctrine”) is introduced. Like ‘cosmic (...) life,’ this term is then used as the basis for a transcultural comparative discussion of positions from ancient Hellenic and Chinese contexts, from South and West Asia, and from Europe. This discussion is organized in the form of three main sections which correspond to three basic themes concerning ‘cosmic life.’ Each of these is developed along the trajectories of related subtopics. In this sense, the first main section presents several views from various times and places in the context of which (cosmic) life is seen as an expressed principle of incessant self-(re)creation through metabolism and partial self-consumption. In the second main section, the transcultural comparative angle is applied to multiple perspectives and variations on the theme of cosmic life as an integral feature of a vast or infinite universe. Finally, the third main section presents family-resemblant views of cosmic life as an integral aspect of cosmic ‘light.’ This last section also links the discussion with some unorthodox and very innovative hypotheses of our time. The main thesis of this chapter is that a future philosophy of cosmic life must draw on a variety of philosophical traditions from different civilizations and, in a spirit of unrestricted openness, translate the ultimate inexhaustibility of all scientific endeavors into a more productive intellectual reality within the expanded scope of a new kind of trans-classical concept of science.

The new discipline of exobiology formed from the intertwining of origin of life research with the search for life or its building blocks on other planets, from 1957-1973. The field was inherently highly interdisciplinary, yet it coalesced very quickly and was responsible in its first twenty years for numerous important contributions to twentieth century life science and planetary sciences such as climatology, the study of mass extinctions, etc. NASA played a very important role in catalyzing the rapid consolidation of exobiology, (...) both through research grants and through sponsored meetings that overcame disciplinary boundaries, bringing together scientists from diverse backgrounds. The presence of a handful of prominent senior scientists such as Joshua Lederberg, Melvin Calvin and Norman Horowitz helped gain credibility for exobiology, in the face of criticism and competition from existing life sciences disciplines. Tensions within the exobiology research community and between NASA-funded science and the academic research community are explored, as are such milestones of discipline formation as journals and professional societies.

While primary malignant brain tumors account for only two percent of all adult cancers, these neoplasms cause a disproportionate amount of cancer-related disabilities and death. The five-year survival rates for brain tumors are the third lowest among all types of cancer. Malignant gliomas comprise the most common types of primary central nervous system tumors and have a combined incidence of five to eight cases per 100,000 people. The median survival rate of conservatively treated patients with malignant gliomas is 14 weeks; (...) with surgical resection alone, 20 weeks; with surgery and radiation, 36 weeks; and with the addition of newer biochemotherapies such as temozolomide and bevacizumab, upward of 14-18 months.The profound cost of caring for terminally ill patients with primary malignant brain tumors raises ethical considerations for the American public; the stewardship of health care dollars for the population at large maintains a juxtaposed tension against a dynamic, necessary balance of hope, care, rehabilitation and research efforts for affected patients and their advocates.

The new discipline of exobiology formed from the intertwining of origin of life research with the search for life or its building blocks on other planets, from 1957-1973. The field was inherently highly interdisciplinary, yet it coalesced very quickly and was responsible in its first twenty years for numerous important contributions to twentieth century life science and planetary sciences such as climatology, the study of mass extinctions, etc. NASA played a very important role in catalyzing the rapid consolidation of exobiology, (...) both through research grants and through sponsored meetings that overcame disciplinary boundaries, bringing together scientists from diverse backgrounds. The presence of a handful of prominent senior scientists such as Joshua Lederberg, Melvin Calvin and Norman Horowitz helped gain credibility for exobiology, in the face of criticism and competition from existing life sciences disciplines. Tensions within the exobiology research community and between NASA-funded science and the academic research community are explored, as are such milestones of discipline formation as journals and professional societies.
