In summary, Einstein proved that gravity is not a force, but a distortion of spacetime. This was demonstrated through the observation of an eclipse in Africa. Today, there is further evidence of this through the difference in time on the ISS and on Earth. However, when searching online or learning from a science teacher, it may still be referred to as a force. This is because it can be viewed as a force in some models, but the more accurate theory, General Relativity, does not use the concept of force to explain gravity. Ultimately, the question of whether gravity is a force or not is a question about our models and can vary depending on the theory being used.
