Einstein’s theory of general relativity

Einstein’s theory of general relativity revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by mass and energy. Explain the concept of spacetime curvature, detailing how massive objects like planets and stars curve the fabric of spacetime around them. Discuss the gravitational effects of this curvature, such as the bending of light and the phenomenon of gravitational time dilation. Furthermore, explore how general relativity has been confirmed through observations such as gravitational lensing and the detection of gravitational waves.
