Isaac newton proposed his ideas of gravity in 1687 with the publication of his seminal work, "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy). In this work, he formulated the law of universal gravitation, describing how objects attract each other with a force that depends on their masses and the distance between them. This laid the foundation for classical mechanics and significantly advanced our understanding of gravitational forces.

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.
No, Newton did not describe the universe as a series of concentric spheres. He is well known for his law of universal gravitation and his laws of motion, which laid the foundation for classical mechanics. Newton's ideas were more focused on explaining the motion of objects and the interactions between them rather than describing the universe as concentric spheres.
To the same extent that they believe gravity exists away from our planet, and for the same reason: scientists observe the predictions made by both ideas. Planets move around our Sun just as gravity predicts they will, and our Universe is exactly as predicted by Big Bang Cosmology.
Aristotle did not discover anything specific about space in the way we understand it today. However, he did propose a geocentric model of the universe and believed in a series of concentric spheres to explain celestial movements. His ideas about space were based on a philosophical perspective rather than scientific observation.

Robert Hooke had several professional rivalries during his lifetime, with one of the most notable being his strained relationship with Isaac Newton. The two men often clashed over scientific ideas and credit for discoveries. Their animosity reached a peak during debates over Newton's laws of motion and gravity.
Sir Isaac newton is best known for mathematical ideas about gravity and motion.
The most famous theory he found out was; gravity.
Isaac Newton with his law of universal gravitation is perhaps best known for explaining gravity, however in modern physics gravitation is described using Albert Einstein's general theory of relativity.
He needed gravity because he had ideas about motion. He believed gravity caused planets to revolve around the sun instead of flying off into space.
