Cosmic Biology in Perspective
N. C. Wickramasinghe, Dayal T. Wickramasinghe, Christopher A. Tout +2
A series of astronomical observations obtained over the period 1986 to 2018 supports the idea that life is a cosmic rather than a purely terrestrial or planetary phenomenon. These…
Incidence of low-density meteoroids of the Polonnaruwa type
N. C. Wickramasinghe, J. Wallis, D. H. Wallis +8
The ingress of micrometeorites of cometary origin with densities below ~ 1 g cm-3 into the Earth could average at least 5 tonne per day. Although much of this is burnt upon entry t…
Fossil diatoms in a new carbonaceous meteorite
N. C. Wickramasinghe, J. Wallis, D. H. Wallis +1
We report the discovery for the first time of diatom frustules in a carbonaceous meteorite that fell in the North Central Province of Sri Lanka on 29 December 2012. Contamination i…
The Polonnaruwa meteorite: oxygen isotope, crystalline and biological composition
Jamie Wallis, Nori Miyake, Richard B. Hoover +7
Results of X-Ray Diffraction (XRD) analysis, Triple Oxygen Isotope analysis and Scanning Electron Microscopic (SEM) studies are presented for stone fragments recovered from the Nor…
Why don't clumps of cirrus dust gravitationally collapse?
Rudolph E. Schild, Carl H. Gibson, Theo M. Nieuwenhuizen +1
We consider the Herschel-Planck infrared observations of presumed condensations of interstellar material at a measured temperature of approximately 14 K (Juvela et al., 2012), the…
DNA sequencing and predictions of the cosmic theory of life
N. Chandra Wickramasinghe
The theory of cometary panspermia, developed by the late Sir Fred Hoyle and the present author argues that life originated cosmically as a unique event in one of a great multitude…
Interstellar Grains: 50 Years On
N. Chandra Wickramasinghe
Our understanding of the nature of interstellar grains has evolved considerably over the past half century with the present author and Fred Hoyle being intimately involved at sever…
Primordial Planets Explain Interstellar Dust, the Formation of Life; and Falsify Dark Energy
Carl H. Gibson, N. Chandra Wickramasinghe, Rudolph E. Schild
Hydrogravitional-dynamics (HGD) cosmology of Gibson/Schild 1996 predicts proto-globular-star-cluster PGC clumps of Earth-mass planets fragmented from plasma at ~0.3 Myr. Protogalax…
Extraterrestrial Life and Censorship
N. Chandra Wickramasinghe
In this article I chronicle a series of landmark events, with which I was personally involved, that relate to the development of the theory of cosmic life. The interpretation of ev…
First life in primordial-planet oceans: the biological big bang
Carl H. Gibson, N. Chandra Wickramasinghe, Rudolph E. Schild
A scenario is presented for the formation of first life in the universe based on hydro-gravitational-dynamics (HGD) cosmology. From HGD, the dark matter of galaxies is H-He gas dom…
On Deliberate Misreferencing as a Tool of Science Policy
F. Hoyle, N. Chandra Wickramasinghe
In the second half of February the impending Giotto encounter of 13 March concentrated our minds on what the encounter might reveal. As an outcome, we issued a fairly widely circul…
Primordial planets, comets and moons foster life in the cosmos
Carl H. Gibson, N. Chandra Wickramasinghe, Rudolph E. Schild
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…
Evolution of primordial planets in relation to the cosmological origin of life
N. Chandra Wickramasinghe, Jamie H. Wallis, Carl H. Gibson +1
We explore the conditions prevailing in primordial planets in the framework of the HGD cosmologies as discussed by Gibson and Schild. The initial stages of condensation of planet-m…
The Origin of Life from Primordial Planets
Carl H. Gibson, Rudolph E. Schild, N. C. Wickramasinghe
The origin of life and the origin of the universe are among the most important problems of science and they might be inextricably linked. Hydro-gravitational-dynamics (HGD) cosmolo…
The Imperatives of Cosmic Biology
Carl H. Gibson, N. Chandra Wickramasinghe
The transformation of organic molecules into the simplest self-replicating living system,a microorganism, is accomplished from a unique event or rare events that occurred early in…
