He used his learning to find out what way comets were facing and he found out the moon has gravity which controls the tide and the exact time the time changes. That proved the sun was in the middle of our solar system this is also known as "heliocentric model." Him finding out gravity came to him over time. All of this information backs up the facts of our next topic Earth.
Isaac Newton predicted that Earth is probably a sphere flush at magnetic poles. which was later proven by La Condamine using degrees. Which persuaded scientists in Europe to look into Newtonian logistics. In details of mathematics, Isaac started using noninteger exponents to advance his methods of rounding a "root of a function". That Gottfried Leibniz also takes some credit for finding calculus. That made a big impact in the field of physic astronomy and math, which allowed them to make a more accurate model how the universe works.
This was my research paper about isaac newton. I covered his biggest discoveries like the earth shape, gravity, lights and optics. He also has a lot of other discoveries but there's too many to name so i just covered the big
