Big Bang theory

The Big Bang theory is the prevailing cosmological model for the observable universe's earliest known periods. It suggests that the universe began as a hot, dense state approximately 13.8 billion years ago and has been expanding ever since.The CMB is the remnant radiation from the Big Bang and is observable as faint microwave radiation coming from all directions in the sky.

Stephen Hawking Theories

Stephen Hawking, one of the most renowned theoretical physicists of the 20th and early 21st centuries, contributed significantly to our understanding of the universe through his groundbreaking theories and research. Hawking proposed that black holes emit radiation due to quantum effects near their event horizons. This radiation, now known as Hawking radiation.

The Moon landing

The Moon landing, specifically the Apollo 11 mission, represents one of the most significant achievements in human history. In 1961, President John F. Kennedy set a bold goal for the United States to land astronauts on the Moon and return them safely to Earth before the end of the 1960s. Apollo 11 was launched from Kennedy Space Center in Florida on July 16, 1969, atop a Saturn V rocket.

Heliocentric model of Galaxy

Proposed by astronomers such as Nicolaus Copernicus in the 16th century, the heliocentric model suggests that the Sun is at the center of the solar system, with the planets—including Earth—orbiting around it.The heliocentric model explains retrograde motion—the occasional backward motion of planets in the sky—as a result of Earth overtaking or being overtaken by other planets in their orbits.

Analyzing the Lifecycle of Star

Analyzing the life cycle of a star involves understanding the various stages it goes through from its formation to its eventual demise.Stars begin their lives as clouds of gas and dust called nebulae.Gravitational forces cause regions within these nebulae to collapse,leading to the formation of protostars.As a protostar forms, gravitational forces continue to pull matter inward.
