Quantum Explained on Instagram: "Einstein’s lensing analogy ?👇 Einstein’s first intuitive explanation of gravitational lensing can be compared to the motion of boats on a flowing river. In this analogy, the river current represents the curvature of spacetime caused by mass, while the boats represent light rays. Just as the boats are forced to deviate from straight paths due to the flow of the river, light is compelled to follow curved geodesics when it passes near a massive object. This simple
