Stephen Hawking is a world renowned theoretical physicist and scientist. He is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes. His book “A Brief History of Time” proved to be a huge success. This video, the first from a series of five, provides information about the life of Mr. Hawking and his work regarding black holes. According to Mr. Hawking, a black hole emerges from the death of a star. As a massive star dies it collapses in on itself, gravity becomes infinitely powerful in the collapsed structure and everything including light gets sucked in. The core of a black hole is infinitesimally small and extremely dense; this causes time and space to be transformed in the core. Recently doubts have been expressed by various scientists about Stephen’s scientific reputation.Part 2: http://www.youtube.com/watch?v=U8V6P1M6_0w Part 3: http://www.youtube.com/watch?v=ziGFbNxFPlM Part 4: http://www.youtube.com/watch?v=UoV1ZH_sYQw Part 5: http://www.youtube.com/watch?v=4KpZNGnJYGc
