Time Dilation

Time dilation, a consequence of Einstein’s theory of relativity, is a mind-bending phenomenon that challenges our intuitive understanding of time. It has been experimentally confirmed and plays a crucial role in modern physics and technology. While the practical applications might not directly impact our daily lives, the concept’s existence shines a light on the fascinating interplay between motion, gravity, and time.

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.

WHAT IS DARK MATTER?

Dark matter refers to a hypothetical form of matter that does not interact with electromagnetic radiation, making it invisible and difficult to detect using traditional astronomical methods. It is called “dark” because it does not emit, absorb, or reflect light, rendering it essentially transparent to electromagnetic radiation. The existence of dark matter is inferred from

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
