LOCAL GROUP

Nestled within the vast expanse of the cosmos, the Local Group stands as a fascinating ensemble of galaxies, with the Milky Way taking center stage in this cosmic ballet. This group, a celestial community spanning about 3 megaparsecs, or roughly 10 million light-years, captivates astronomers and stargazers alike with its intricate structure and dynamic interactions.

What is Cosmological Constant – (Λ)

Einstein introduced the cosmological constant into his equations as a repulsive force to counteract gravity, aiming to describe a static universe. However, in 1929, Edwin Hubble’s discovery of the expanding nature of the universe challenged Einstein’s assumptions, leading him to regard the cosmological constant as his “greatest blunder.”

What is Cold Dark Matter?

Cold dark matter (CDM) is a theoretical form of matter that does not interact electromagnetically but exerts a gravitational influence on visible matter. Unlike ordinary matter, such as protons and electrons, which are composed of elementary particles known as baryons, cold dark matter consists of non-baryonic particles that remain undiscovered.

Lambda-CDM Model: Unveiling the Foundations of Big Bang Cosmology

The Lambda-CDM model, also known as the Lambda Cold Dark Matter model, is a prevailing cosmological framework that describes the evolution and structure of the universe. This model combines two key components: Lambda (Λ), representing dark energy, and Cold Dark Matter (CDM). In addition, ordinary matter plays a significant role in shaping the universe. In

Nucleosynthesis During the Big Bang: Exploring the Formation of Light Elements

Nucleosynthesis during the Big Bang is a captivating phenomenon that sheds light on the creation of light elements in the nascent stages of the universe. Taking place within minutes of the Big Bang, this process occurred under extreme temperatures and densities, enabling nuclear reactions to give rise to the first atomic nuclei.
