INHOMOGENEITIES. “The initial small density fluctuations from which structures form lead to fluctuations in the temperature of the CMB.” (CMB = cosmic microwave background). https://lnkd.in/e6ifiQMn View in LinkedIn

A LITTLE LATER. “The Universe becomes neutral and photons stop scattering and subsequently free-stream through the Universe. This process is known as decoupling and occurs at t ∼ 0.37Myr. The resulting Cosmic Microwave Background has a black body spectrum with present day temperature.” https://lnkd.in/e6ifiQMn View in LinkedIn

PARTIAL INTERCONNECTEDNESS. Systemism (“everything hangs together with some other thing or things”) steers a middle course between holism (“all things hang together”) and atomism (“everything goes its own way”). No part of the universe is completely isolated but every thing is isolated in some respect from other things.” https://lnkd.in/eZVUsMdz View in LinkedIn

Early cosmos. “The Universe is composed of nuclei and electrons, and photons scatter frequently off these charged particles. As the Universe expands and cools the energy of the photons drops and atoms form. This process is known as recombination and occurs at t ∼ 0.25 Myr.” https://lnkd.in/e6ifiQMn View in LinkedIn

OTHER CANDIDATES. “Our hypothesis predicts that other Chicxulub-size craters on Earth are more likely to correspond to an impactor with a carbonaceous chondritc composition than expected from the carbonaceous chondritc composition fraction of MBAs.” https://www.nature.com/articles/s41598-021-82320-2 View in LinkedIn

LEAD CANDIDATE. “Strong evidence suggests that the Chicxulub impact led to the K/T mass extinction event, which was the largest in the past ~250 Myr and brought about the demise of the dinosaurs.” https://www.nature.com/articles/s41598-021-82320-2 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
