## Black Hole and Subrahmanyan Chandrashekhar

Subrahmanyan Chadrashekhar was the first person who prove that Black Holes like solutions can be real. In 1931 he calculated that a stationary astrophysical object above a certain limiting mass has no stable solutions. At that time this idea was appreciated by many scientist but Eddington opposed his idea. Eddington suppose in Read more…

## Cosmology From Newton to Hubble

The historical idea of structure and origin of the universe shows that human always put his self on the centre of the creation of the universe. We started from the idea that earth is in the rest and all stars are rotating around us. Slowly it was observed that motion Read more…
