🕳️ Einstein Ring & Gravitational Deflection: According to General Relativity, immense mass warps spacetime. Photons traveling past a black hole follow curved null geodesics. When a background star aligns directly behind the singularity, light rays bend symmetrically into a closed glowing circle called an Einstein Ring.
