Gravitational Lensing

Normal lenses such as the ones used in a magnifying glass or a pair of spectacles bends the light rays that pass through them by refraction and focuses the light somewhere (such as in your eye). Gravitational lensing is among the first evidences of Albert Einstein’s general theory of relativity – simply put, mass bends light. The gravitational field of a massive ..


Gravitational Waves

Gravitational Waves were for the first time discovered in February, 2016, 100 years after they were hypothesized by Albert Einstein in 1916. These waves were detected by the scientists working at two LIGO (Laser Interferometer Gravitational-wave Observatory) facilities in United States. LIGO scientists detected these gravitational waves produced by collision of two black holes located ..
