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…
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…
Supermassive galactic centre with repulsive gravity
Trevor W. Marshall, Max K. Wallis
Repulsive gravity has its origin in the 1939 article of Oppenheimer and Snyder which describes a collapsar, that is an idealized star of non-interacting material (dust) collapsing…
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…
