Is Gravity An Illusion?

The video explores the contrasting views of gravity by Newton and Einstein. It begins with Newton's concept of gravitational force and introduces Einstein's revolutionary idea that gravity is not a force but an effect of curved spacetime. The video explains frames of reference, inertial frames, and how accelerated frames mimic gravitational fields. It introduces Einstein's equivalence principle, suggesting that gravity is an illusion caused by the upward acceleration of Earth's surface. The video concludes with an introduction to general relativity, explaining how it redefines our understanding of motion and gravity.
