question 3 \\(\bigstar\\) key question\
describe how einsteins general theory of relativity explained gravity (use your notes!).

Explanation:

Einstein's General Theory of Relativity redefined gravity as not a direct force between masses, but a geometric effect: massive objects warp the fabric of spacetime (a four-dimensional combination of space and time). Other objects move along the curved paths created by this warped spacetime, which we perceive as gravitational attraction.

Answer:

According to Einstein's General Theory of Relativity, gravity is not a traditional force acting between masses. Instead, massive objects cause a curvature or warping of the four-dimensional fabric of spacetime. Any object moving through this warped spacetime follows a curved path, and this curved motion is what we observe and experience as gravity. For example, the Earth orbits the Sun not because of a pull, but because the Sun's mass warps the spacetime around it, and the Earth follows the natural curved path in this warped geometry.
