Understanding the Theory of General Relativity

Albert Einstein’s eureka moment came when he realized that the force we call gravity isn’t a traditional force at all. Instead, he conceived of gravity as the curvature of space-time caused by mass and energy. In other words, massive objects like stars and planets warp the fabric of space and time around them, and other objects, including light, move along these curved paths.

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

What is Recombination & Cosmic Microwave Background?

the universe had cooled down sufficiently for electrons and protons to combine and form neutral hydrogen atoms. Prior to recombination, the high temperature and density of the universe prevented electrons from stably binding with protons, resulting in a plasma of charged particles that strongly scattered light. This scattering made the early universe opaque to photons.
