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…
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…
Bacterial morphologies in carbonaceous meteorites and comet dust
N. Chandra Wickramasinghe, Max K. Wallis, Carl H. Gibson +3
Three decades ago the first convincing evidence of microbial fossils in carbonaceous chondrites was discovered and reported by Hans Dieter Pflug and his collaborators. In addition…
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…
