Edmond Halley and Alexis Clairaut made significant contributions to the understanding of the orbits of comets and the shape of the Earth using Newton's ideas of mathematics and gravity. Halley famously predicted the return of Comet Halley by applying Newton's laws of motion and universal gravitation. Clairaut extended this work by using Newtonian principles to determine that the Earth is not a perfect sphere but an oblate spheroid, confirming that the planet's equatorial diameter is larger than its polar diameter due to its rotation. These discoveries laid the foundation for modern celestial mechanics and geophysics.
Albert Einstein's important phase of fame came in 1915 when he introduced the general theory of relativity, revolutionizing our understanding of gravity and the universe. This led to him becoming a household name and one of the most influential scientists of the 20th century.
Isaac Newton did not discover gravity. Practically everybody already knew that when you let go of something in your hand, it falls to the ground, and nobody paid any attention to the few who didn't know it. What Isaac Newton did was explain exactly how it works, with numbers. With that simple new knowledge, it was possible to explain how and why the moon revolves around the Earth, how the planets and comets revolve around the sun, and how to launch spacecraft that can carry people to the moon, land cameras on Mars, sail probes out of the solar system, and hang satellites up in the sky that can bring you 900 TV channels that have nothing on. Of course, if none of that is useful or interesting to you, then Newton's discovery wasn't important.
"Gravity" is the cause of orbital motion. No gravity . . . no orbits, and things just sail away in straight lines. Without gravity, there's no such thing as a satellite of anything.
Without gravity we would HAVE NO LIVES. For instance, gravity keeps our Earth together; and gravity is an important component in making the Sun produce energy via nuclear fusion.
It is a common misconception that gravity does not exist in space. The truth is that in space, gravity is the most important force in governing the movement of large objects. You cannot plot a trajectory in space without understanding gravity.

They were able to find the orbit of a comet and predict the year of it's return.
Gravity is the major force in the Universe controlling matter. Gravity controls the structure of the Universe.
It proved that Isaac newton's Theories Of Motion And Gravity are correct.
The Law of Gravity was Isaac Newton's greatest discovery. This Law ushered in a New Age of Mathematics based science; settled a controversy about the heavens; and extended the domain of science to the Universe.
His great discovery was the law of gravity
Gravity
discovery of gravity by Sir Isaac Newton
Galileo Galilei. Perhaps his most important discovery was finding that acceleration due to gravity is independent of the objects mass.
He was curious and driven. He observed things very carefully. He had a brilliant mind and a brilliant grasp of mathematics. He figured out which questions were the important ones. Put all that together, and you get discovery.
