Einstein argued that space and time are actually one unified thing called spacetime. The concept of what gravity actually is remained mysterious until Albert Einstein figured it out in his Theory of Relativity which was developed between 19. Newton used his ideas to propose that artificial satellites were actually possible some 300 years before anyone actually launched one into Earth orbit. In fact, it was the falling apple that led Newton to prove that the Moon is really falling in its orbit around the Earth. Therefore while the Earth’s gravity attracts you and holds you on the surface, your gravity also attracts the Earth! Newton also proved mathematically that gravitational force controlled all the orbits in our solar system – both those of planets going around the Sun as well as the orbits or moons around various planets. Newton’s theory says that all things possess gravity and attract each other across space. The function of gravity on the solar system was largely unknown until Isaac Newton proposed his theory of universal gravitation in 1665. Galileo also explored gravitation using ramps and pendulums – something that even the youngest students can experience and begin to understand in school today. ![]() ![]() It was Galileo who first realized that gravity acts on all things equally and that everything falls at the same rate regardless of its mass. ![]() There is an adage in astronomy that “ Gravity controls everything.” Gravity was first explored mathematically and scientifically by Galileo in the early 1600’s. Gravity is one of the most fundamental, and most mysterious, forces in our universe.
