Fortuitous

A Statistical Test of Correlations and Periodicities in the Geological Records,critically examined by adopting a method of Ertel used by Matsumoto & Kubotani but by applying it more directly to the extinction and cratering records. It is shown that on the null-hypothesis of random distribution of crater ages, the observed correlation has a probability of occurrence of 13%. How

The Galactic Theory of Mass Extinctions: An Update,lux is partly modulated by the dynamics of the Milky Way Galaxy. Geologic evidence for impact (ejects and large impact craters) has been found at times of mass extinction events, and the record of large dated craters shows a significant correlation with extinctions. Statistical analyses suggest that

Oort Cloud Comet Perihelion Asymmetries: Galactic Tide, Shower or Observational Bias?,classes with original energies designated as new or young. Perihelion directions are determined in galactic, ecliptic and geocentric equatorial coordinates. Asymmetries are detected in the scatter and are studied statistically for evidence of adiabatic galactic tidal dynamics, an impulse-induced sho

The Dynamical Evolution of the Atens, the time interval of one million years. The dynamical model was a 6-body Solar System, where the perturbations of Uranus and Neptune were ignored, and where Mercury’s mass was added to the Sun’s mass. Thus mean motion resonances, secular resonances and the Kozai resonance were fully taken into acco
