The Lambda Cold Dark Matter Model

The Lambda Cold Dark Matter (ΛCDM) model, also known as the Lambda Cold Dark Matter cosmological model, is the prevailing framework in cosmology for explaining the large-scale structure and evolution of the universe. It combines the effects of dark energy, dark matter, and ordinary matter to provide a comprehensive description of the universe’s composition and …

Review: Recent Advances in Beyond the Standard Model Cosmology

arXiv:2401.04735 : Recent advances of Beyond the Standard model cosmology Introduction: The standard cosmological model incorporates concepts like inflation, baryosynthesis, and dark matter/energy, which are believed to extend Beyond the Standard Model (BSM) of fundamental physics. The paper explores various BSM cosmological features, which include signals that challenge the standard ΛCDM cosmology. These signals are …

[Astropy] Units conversion

First, we need to install it using pip Just simply type ‘pip install astropy’ in the terminal to install it The Astropy module includes many constants commonly used in space, so you don’t need to specify them separately when coding! For example, the well-known gravitational constant value is:   G=6.67×10−11 N⋅m^2/kg^2 Previously, to use this value, …

Does the moon remain the same size?

Have you ever heard that the moon has been shrinking? Recent scientific observations suggest that the moon is gradually shrinking. Over time, the moon’s interior cools and contracts, causing its surface to wrinkle and create cliffs known as “moonquakes.” These findings challenge the traditional view of the moon as a static and unchanging celestial body. …

Density Parameter (Ω)

Density Parameter ( Ω )  The density parameter is a dimensionless quantity used in cosmology to describe the ratio of the actual density of matter or energy in the universe to the critical density. The critical density is the density required for the universe to be flat, meaning that it has just enough mass and …
