Is there anything like ghost ?

 By  Debjani Roy  |  Monday, March 8, 2021

Don't watch those horror movies and believe about ghosts, they are just the imagination of humans, humans are afraid by the fear of unknown. For example, in older periods, they could have seen a bush move. There are many reasons for the bush to move, but humans imagined that the dead people come again!

What is relativity theory of Einstein?

 By  Kamal Bose  |  Sunday, February 7, 2021

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity.
