Isaac Newton is a brilliant English Physicist and mathematician well known as the father of Astrophysics which is based on Newton’s profound understanding of gravitation and classical mechanics. He is mostly known as the master of Gravity which marked his contribution to science and extensively mathematics.

He developed the laws of motion and the rule of universal gravitation in his seminal work Philosophiae Naturalis Principia Mathematica, he brilliantly described the motion of celestial bodies and their interactions. These ideas, also referred to as Newtonian mechanics, served as the foundation for classical physics and have influenced how we perceive the cosmos for many years.

2.Nicolaus Copernicus (1473-1543)

Often regarded as the father of observational astronomy, Galileo’s astronomical observations using the newly invented telescope provided critical evidence in support of Copernicus’ heliocentric model; the idea that the sun is the centre of the solar system. He was influenced by the likes of Isaac Newton, Galielo Galieli and Johannes Kelper.

His observations of Jupiter’s moons, the phases of Venus, and the rugged lunar surface shattered the Aristotelian view of a perfect, unchanging celestial realm. Galileo’s work not only advanced our understanding of the solar system but also set the stage for the scientific method and modern astronomy making history.

Albert Einstein was a famous German physicist of the 20^th century known for his contribution in the field of science and even won the Nobel Prize for his contribution to physics. A new understanding of gravity was provided by Einstein’s general relativity theory, which was published in 1915 and completely changed the field of astrophysics.

This hypothesis gave rise to the idea of gravitational lensing by explaining how light would bend in the presence of enormous objects like stars and black holes. Black holes were also foreseen by general relativity, which also gave a framework for comprehending the universe’s expansion.
