As I said near the end of part 3, I am thinking that the 3 types of recession rates that we have in the LightCone calculator might be a logical follow-on. Plus perhaps a post-script of some sorts, as you have suggested before (and which you indicated that you are willing to write).marcus said:
The LCDM cosmological model is a widely accepted theory in modern astrophysics that describes the evolution of the universe. It stands for Lambda-Cold Dark Matter model, where Lambda represents a cosmological constant and Cold Dark Matter refers to a type of matter that does not interact with light or other forms of electromagnetic radiation.
The LCDM model simplifies the complex mathematical equations of general relativity and cosmology by making assumptions such as a homogenous and isotropic universe, and treating dark matter and dark energy as separate components. This allows for a more manageable and simplified mathematical representation of the universe's evolution.
The cosmological constant, represented by the Greek letter Lambda, is a term in Einstein's field equations that describes the energy density of empty space, also known as vacuum energy. In the LCDM model, the cosmological constant is used to explain the observed acceleration of the universe's expansion.
The LCDM model suggests that the universe is made up of about 5% ordinary matter, 27% dark matter, and 68% dark energy. Ordinary matter clumps together due to gravity, forming galaxies and clusters, while dark matter provides the necessary gravitational pull to hold these structures together. Dark energy, on the other hand, is believed to be responsible for the accelerating expansion of the universe.
The LCDM model is supported by various lines of evidence, including observations of the cosmic microwave background radiation, the large-scale distribution of galaxies, and the accelerating expansion of the universe. It also successfully predicts the observed abundance of light elements, the formation of galaxies and large-scale structures, and the distribution of dark matter in the universe.
