Adherents have a hard time explaining, for instance, why airplanes do not fall The theory, if taken seriously, implies that the default position for all airplanes is on the ground. That is what theories are for In the language of science, a theory is an explanation of why and how things happen For gravity, we use einstein's theory of general relativity to explain why things fall A theory starts as one or more hypotheses, untested ideas about why something happens.
Albert einstein’s 1915 theory proposed a radical departure, suggesting that gravity is not a force but rather a distortion in spacetime caused by massive objects. The strength of a scientific theory lies in its explanatory power and predictive capacity, as explained in detail by this helpful resource on why is evolution considered a scientific theory. Gravity as geometry in 1915, einstein unveiled his general theory of relativity, a breathtakingly beautiful and complex theory that redefined gravity According to general relativity, mass and energy warp the fabric of spacetime, and this curvature tells objects how to move Imagine placing a heavy bowling ball on a trampoline. Do we need a new theory of gravity
