Fred Hoyle: Pioneer in Nuclear Astrophysics
PERSONALITY Fred Hoyle: pioneer in nuclear astrophysics Fred Hoyle, who died in 2001, is best known as a cosmologist. But, as Simon Mitton relates, his career in physics began with the weak interaction and moved on to a crucial discovery in nuclear physics. Fred Hoyle, the great cosmologist, nuclear astrophysicist and contro versialist, was born 90 years ago in the beautiful county of Yorkshire in the north of England. Hoyle's first science teacher was his father, who supplied the boy with books and apparatus for chemistry exper iments. By the age of 15 he was making highly toxic phosphine (PH3) Later in life Hoyle seldom worked at a desk in a faculty building, in his mother's kitchen, and terrifying his young sister with explosions. preferring a comfortable armchair at home.

From HGD, the dark matter of galaxies is H-He gas dominated planets (primordial-fog-particle PFPs) in million solar mass clumps (protoglobularstar- cluster PGCs), which formed at the plasma to gas transition temperature 3000 K. Stars result from mergers of these hot-gas-planets. Over-accretion causes stars to explode as supernovae that scatter life-chemicals (C, N, O, P, S, Ca, Fe etc.) to other planets in PGC clumps and beyond. These chemicals were first collected gravitationally by merging PFPs to form H-saturated, high-pressure, dense oceans of critical-temperature 647 K water over iron-nickel cores at ~ 2 Myr. Stardust fertil- izes the formation of first life in a cosmic hot-ocean soup kitchen comprised of all planets and their moons in meteoric communication, > 10100 kg in total. Ocean freezing at 273 K slows this biologi- cal big bang at ~ 8 Myr. HGD cosmology confirms that the evolving seeds of life are scattered on intergalactic scales by Hoyle-Wickramasinghe cometary panspermia. -

The theory that bacteria and viruses similar to those discovery of time-variable spikes in methane observed by the Curiosity on Earth exist in comets, other planets and generally throughout the galaxy was developed as a serious scientific discipline from the early 1980’s [1-4]. Throughout the past three decades this idea has often been Relectivity Spectrum the subject of criticism, denial or even ridicule. Even though many discoveries in astronomy, geology and biology continued to provide supportive evidence for the theory of cosmic life, the rival theory of Earth-centered biology has remained deeply rooted in scientific culture. However, several recent developments are beginning to strain the credibility of the standard point of view. The great abundance of highly complex organic molecules in interstellar clouds [5], the plentiful existence of habitable planets in the galaxy numbering over 100 billion and separated one from another just by a few light years [6], the extreme space-survival properties of bacteria and viruses -make it exceedingly difficult to avoid the conclusion that the entire galaxy is a single connected biosphere. -

World Scientific proudly presents books by Chandra Wickramasinghe THE SEARCH FOR OUR COSMIC ANCESTRY by Chandra Wickramasinghe (Buckingham Centre for Astrobiology, UK) “The author is today’s foremost expert on panspermia, having inherited that mantle from the iconic astronomer of the 20th century Sir Fred Hoyle who, with Wickramasinghe as his pupil, strongly re- introduced the subject in the early 1970’s. He makes a compelling case for panspermia conveying a cosmic imperative for biology.” Gilbert V Levin Principal Investigator of NASA’s Mars Viking Mission of 1976 Discoverer of evdience for Microbial Life on Mars Arizona State University “The book is accessible to those interested in an appreciation of a central question that spans VINDICATION OF COSMIC all ages, and scientists and science students, who are seeking coverage of this pioneering BIOLOGY subject matter.

Fermi's Paradox-The Last Challenge for Copernicanism?
Fermi’s Paradox – The Last Challenge for Copernicanism? Milan M. Cirkovi´c´ Astronomical Observatory Belgrade, Volgina 7, 11160 Belgrade, Serbia & Department of Physics, University of Novi Sad, Trg Dositeja Obradovi´ca 4, 21000 Novi Sad, Serbia e-mail: [email protected] Abstract We review Fermi’s paradox (or the ”Great Silence” problem), not only arguably the oldest and crucial problem for the Search for ExtraTer- restrial Intelligence (SETI), but also a conundrum of profound scien- tific, philosophical and cultural importance. By a simple analysis of observation selection effects, the correct resolution of Fermi’s paradox is certain to tell us something about the future of humanity. Already a more than three quarters of a century old puzzle – and a quarter of century since the last major review paper in the field by G. David Brin – Fermi’s paradox has generated many ingenious discussions and hy- potheses. We analyze the often tacit methodological assumptions built into various answers to this puzzle and attempt a new classification of the numerous solutions proposed in an already huge literature on the subject. Finally, we consider the ramifications of various classes of hypotheses for the practical SETI projects. Somewhat paradoxically, it seems that the class of (neo)catastrophic hypotheses gives, on bal- ance, the strongest justification for guarded optimism regarding our current and near-future SETI efforts. Key words: astrobiology – extraterrestrial intelligence – Galaxy: evolution arXiv:0907.3432v1 [astro-ph.EP] 20 Jul 2009 – history and philosophy of astronomy – observation selection effects If you do not expect the unexpected, you will not find it; for it is hard to be sought out and difficult. -

Primordial Planets, Comets and Moons Foster Life in the Cosmos
Primordial planets, comets and moons foster life in the cosmos Carl H. Gibsona*, N. Chandra Wickramasingheb and Rudolph E. Schildc a UCSD, La Jolla, CA, 92093-0411, USA; b Cardiff Univ., Cardiff, UK; c Harvard, Cambridge, MA, USA ABSTRACT A key result of hydrogravitational dynamics cosmology relevant to astrobiology is the early formation of vast numbers of hot primordial-gas planets in million-solar-mass clumps as the dark matter of galaxies and the hosts of first life. Photon viscous forces in the expanding universe of the turbulent big bang prevent fragmentations of the plasma for mass scales smaller than protogalaxies. At the plasma to gas transition 300,000 years after the big bang, the 107 decrease in kinematic viscosity ν explains why ~3x107 planets are observed to exist per star in typical galaxies like the Milky Way, not eight or nine. Stars form by a binary accretional cascade from Earth-mass primordial planets to progressively larger masses that collect and recycle the stardust chemicals of life produced when stars overeat and explode. The astonishing complexity of molecular biology observed on Earth is possible to explain only if enormous numbers of primordial planets and their fragments have hosted the formation and wide scattering of the seeds of life virtually from the beginning of time. Geochemical and biological evidence suggests that life on Earth appears at the earliest moment it can survive, in highly evolved forms with complexity requiring a time scale in excess of the age of the galaxy. This is quite impossible within standard cold-dark-matter cosmology where planets are relatively recent, rare and cold, completely lacking mechanisms for intergalactic transport of life forms. -
