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
ALMOST FORGOTTEN. “In the upper reaches of pleasure and on the boundary of fear is a little studied emotion – awe.” https://lnkd.in/ew43YnMu View in LinkedIn
AUGMENTED IMPACTOR. “This population could increase the impact rate of long-period comets capable of producing Chicxulub impact events by an order of magnitude.” https://www.nature.com/articles/s41598-021-82320-2 View in LinkedIn
FRAGMENTED METEORS. “Here, we show that a fraction of long-period comets are tidally disrupted after passing close to the Sun, each producing a collection of smaller fragments that cross the orbit of Earth.” https://www.nature.com/articles/s41598-021-82320-2 View in LinkedIn
