THE WORLD AS WE DO NOT KNOW IT. “Some in quantum physics have have stated that information absolutely travels from future to past as well as from past to future.” https://lnkd.in/ezYv-wzR View in LinkedIn

THE BEAST. “We move on to the observational evidence for cold, non-baryonic dark matter, on scales ranging from individual galaxies to the Universe as a whole. Understanding the distribution of DM, in particular within the Milky Way, is crucial for its detection.” (DM = dark matter). https://lnkd.in/e6ifiQMn View in LinkedIn

BACKGROUND. “A brief introduction to cosmology, at the level of an undergraduate/bachelors course, focusing on the topics that are most relevant for DM.” (DM = dark matter). https://lnkd.in/e6ifiQMn View in LinkedIn

THE START. “We look at the observational evidence for dark matter, from observations of galaxies, galaxy clusters, the anisotropies in the cosmic microwave background radiation and large scale structure.” https://lnkd.in/e6ifiQMn View in LinkedIn

Proton + Neutron. “The subsequent production of the nuclei of the light elements occurs via a chain of reactions: p+n → D, D+p → 3He, D+D → 4He.” https://lnkd.in/e6ifiQMn View in LinkedIn

THE SLANT. “These lecture notes aim to provide an introduction to dark matter from the perspective of astrophysics/cosmology.” https://lnkd.in/e6ifiQMn View in LinkedIn

ORIGIN OF MATTER. “(Big Bang) Nucleosynthesis is the synthesis of the nuclei of the light elements (Deuterium, D, Helium-3, 3He, Helium-4, 4He, and Lithium-7, 7Li) when the Universe was seconds to minutes old.” https://lnkd.in/e6ifiQMn View in LinkedIn

“FIGURE 1: Evolution of the log of the density of the universe, ε, with the log of the scale factor, a. The universe starts off radiation dominated (red line), becomes matter dominated (blue) and then at late times is dominated by the cosmological constant (burgundy).” https://lnkd.in/e6ifiQMn View in LinkedIn

DARK MATTER AND DARK ENERGY are the subject of the next section in this blog. This is clearly the elephant in the room of modern astrophysics, since it is so enormous and so unresolved. It is a reminder of how much we are still in the Dark Ages, a backward species. View in LinkedIn
