    Light Mystery
Click For Summary
Black holes exert a powerful gravitational pull that affects light, leading to phenomena like gravitational lensing. Light behaves as a physical particle, but its speed is influenced by the medium it travels through, being slower in denser materials compared to a vacuum. The bending of light occurs around all sources of gravity, though the effect is negligible for smaller masses. The discussion also touches on the equivalence of mass and energy in the context of gravity, emphasizing that light, as part of the electromagnetic spectrum, experiences similar bending effects as other waves. Overall, the conversation highlights the complex relationship between light, gravity, and the fabric of spacetime.
