GRAVITY-CENTRIC. “Structures (galaxies, galaxy clusters) form via gravitational instability: small initial over-densities grow due to gravity. How the perturbations grow, and hence how galaxies cluster, depends on the contents of the Universe.” https://lnkd.in/e6ifiQMn View in LinkedIn

This Hubble picture could easily be an exotic imaginary mountain landscape. https://lnkd.in/eSwH5GEm View in LinkedIn

PEAK EXPERIENCES. “Awe is a lightning bolt that marks in memory those moments when the doors of perception are cleansed and we see with startling clarity what is truly important in life. Moments of awe may be the most important, transformative experiences of life.” (Page 35) https://lnkd.in/eTQYza-q View in LinkedIn

SO ENDS this first of two weekends focusing on a new physiological explanation for the demise of the dinosaurs following a meteor(s) impaction. We all understand the catastrophic physical causes of extinction, but that could not account for the majority of the dieouts. That there was a metabolic consequence of large SO2 dust clouds is a credible, testable and novel idea in a field rather replete with rather pedestrian explanations. https://lnkd.in/eqAYpQg2 View in LinkedIn

CORRELATIONS. “The K/Pg ejecta layer is the only global stratigraphic marker in the geological record, allowing correlation of events worldwide. In the last 20 years much has been learned about the Chicxulub crater and the K/Pg boundary; however what is perhaps most interesting are the questions remaining, which include fundamental aspects of Chicxulub impact and its environmental effects.” https://lnkd.in/eqAYpQg2 View in LinkedIn

DISTANT ENERGY WAVE. “Energy release results in intense fracturing and deformation at the target site, generating seismic waves traveling the whole Earth.” https://lnkd.in/eqAYpQg2 View in LinkedIn

CATASTROPHIC IMPACT. “The impact and crater formation occur instantaneously, with excavation of the crust down to ~25 km depths in fractions of a second and lower crust uplift and crater formation in the next few hundred seconds.” https://lnkd.in/eqAYpQg2 View in LinkedIn

WELL CHARACTERIZED. “The Yucatan carbonate platform is an ideal place to have the crater, tectonically stable with no volcanic activity, having formed by slow deposition of carbonate sediments. These characteristics permit high resolution imagery of the crater underground structure with unprecedented detail.” https://lnkd.in/eqAYpQg2 View in LinkedIn

MASSIVE CRATER. “The crater is about ~200 km in rim diameter, half on-land and half off-shore with geometric center at Chicxulub Puerto, making it possible to use land, marine and aerial geophysical methods.” https://lnkd.in/eqAYpQg2 View in LinkedIn

THE NATURE OF REALITY. “The totality of perception, including every memory, is notoriously unreliable and misleading. How then, should one try to comprehend the fundamental nature of consciousness? Moreover, is the external world our senses are seemingly reporting to us about really “out there?” https://link.springer.com/chapter/10.1007/978-3-030-03633-1_14 View in LinkedIn
