BIG BANG THEORY

BIG BANG THEORY

The Big Bang Theory is a cosmological model that explains the large-time scale evolution of the observable universe. The model explains how Universe evolved and expanded from an initial point with extremely high temperature and density to how we observe it today. The Universe expanded from this point of singularity…

TIMELINE OF BIG BANG COOLING

TIMELINE OF BIG BANG: COOLING

With the advent of Cosmic inflation, the Universe expanded at a speed faster than the speed of light resulting in an instantaneous increase in the volume of space by 1078.  Due to this, the Universe continued to decrease in temperature and density, and therefore the average energy per particle was…

TIMELINE OF THE BIG BANG: SINGULARITY

TIMELINE OF THE BIG BANG: SINGULARITY

According to the current Big Bang Model, it suggests that the Universe was dense and small at the beginning and since then it has been expanding rapidly due to inflationary pressure. We will go through those different phases of the formation of the Universe from the occurrence of Big Bang…

FEATURES OF BIG BANG

The Big Bang Theory helps explain and predict various phenomena in the Universe that astrophysical observations suggest. Based on this, we will study 2 models that physicists had discovered in the early 20th century but failed to gather enough evidence to explain why this was happening. However, after the advent…
