Google Doodle celebrates Stephen Hawking’s 80th birthday

Saturday’s Google Doodle pays homage to the late Stephen Hawking, perhaps the most famous scientist of his time, who sought to explain the universe to millions.

The renowned British theoretical physicist and cosmologist’s work focused on increasing our understanding of black holes — dying stars that’ve collapsed on themselves, forming a core of such density and strong gravitational attraction that nothing, not even light, can escape.
