Who discover gravity?

Answer 1

Gravity was discovered by Sir Isaac newton.
That's like asking who invented planets, or water. Nobody had to invent gravity.

It was always there, but the English Physicist/Mathematician Sir Isaac Newton

gets the credit for explaining how it works, around the year 1700 or so.
People had been aware of gravitatonal force for hundreds of years before English Scientist Sir Isaac Newton wrote his Principia in 1687 which was the first attempt to set out the laws of gravity.

Answer 2

newton found out gravity.

Additional answer

I imagine a lot of people knew about gravity without exactly knowing what it was. Whenever they dropped anything it always fell downwards. But Newton was the first person to think seriously about it and put his thoughts into words.

Answer 3

Sir Isaac Newton is credited with discovering the concept of gravity in the 17th century. He formulated the law of universal gravitation, which states that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
