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

OTHER CANDIDATES. “It predicts a larger proportion of impactors with carbonaceous chondritic compositions than would be expected from meteorite falls of main-belt asteroids.” https://www.nature.com/articles/s41598-021-82320-2 View in LinkedIn

MASSIVE IMPACTOR. “Our hypothesis explains the composition of the largest confirmed impact crater in Earth’s history as well as the largest one within the last million years.” https://www.nature.com/articles/s41598-021-82320-2 View in LinkedIn

CONSISTENT DATA. “This new rate would be consistent with the age of the Chicxulub impact crater, thereby providing a satisfactory explanation for the origin of the impactor.” https://www.nature.com/articles/s41598-021-82320-2 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
