In the universe, light travels enormous distances before it reaches us. To take an example, the closest star to Earth, Proxima Cenaturi, is around 4.3 light years or about 40,208,000,000,000 km away. So, while travelling such enormous distances, some forces act upon the light and “bend” ...

So , today I am going to talk about gravitational lensing . What is it ? Why we should know about it , lets see . Gravitational lensing is a phenomenon that occurs when the gravity of a massive object bends the path of light from a distant object, causing its image to be distorted. This can ...

if inertial mass and gravitational mass are exactly the same, everything will fall at the same speed, making it hard for a falling observer to establish that he is in a gravitational field. Einstein hypothesized that, not only would it be hard, but in fact impossible. This thought lead him down a...
