ONE OF THREE. “Chicxulub is one of only three multi-ring craters documented in the terrestrial record and impact has been related to the global environmental/ climatic effects and mass extinction that mark the Cretaceous/Paleogene (K/Pg) boundary.” https://lnkd.in/eqAYpQg2 View in LinkedIn

WIMP HALOS. “The first WIMP halos to form are roughly Earth mass microhalos.” (WIMP = weakly interacting massive particle). https://lnkd.in/e6ifiQMn View in LinkedIn

HISTORICAL FAVORITE CRATER. “The Chicxulub impact crater is part of a select group of unique geological sites, being a natural laboratory to investigate crater formation processes and global effects of large-scale impacts.” https://lnkd.in/eqAYpQg2 View in LinkedIn

WIMP: weakly interacting massive particle (WIMP), heavy, electromagnetically neutral subatomic particle that is hypothesized to make up most dark matter and therefore some 22 percent of the universe.” https://lnkd.in/eEwV_wZp View in LinkedIn

COSMIC STRUCTURES. “Perturbations on scales smaller than galaxy clusters are erased, and structure formation is ‘top down’: large objects form first.” https://lnkd.in/e6ifiQMn View in LinkedIn

DARK MATTER. “The nature of DM affects the evolution of the density perturbations. Cold dark matter (CDM) decouples when non-relativistic, and has very small velocity dispersion today. Hot dark matter (HDM) decouples when relativistic and has non-zero velocity dispersion today.” Thus dark matter is closely interconnected to gravity. https://lnkd.in/e6ifiQMn View in LinkedIn

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

STAGE 1. NUCLEOSYNTHESIS. “The Universe is radiation dominated at early times, with nucleosynthesis, the synthesis of the nuclei of the light elements, starting ∼ 1 s after the Big Bang.” https://lnkd.in/e6ifiQMn View in LinkedIn

“TABLE 1 summarises the history of the Universe.” (Marvelous, you cannot make this up!). https://lnkd.in/e6ifiQMn View in LinkedIn
