What Is Gravitational Lensing?

The video explores gravitational lensing, a phenomenon where massive objects bend space-time, affecting the path of light. It explains how lenses work, Einstein's prediction of gravitational lensing, and its first observation in 1979. The video discusses various lensing effects, such as the Einstein Cross and Einstein Ring, and how these effects help discover celestial objects, including planets. The video concludes with an invitation to join Scishow Space for more exploration.
