Superstar Kamal Haasan, Siddharth, Kajal Aggarwal, Tamannaah Bhatia and a host of other celebs from south Indian films have expressed grief at the death of Stephen Hawking, who passed away March 14.

Stephen Hawking was a theoretical physicist, cosmologist, author and the director of research at the Center for Theoretical Cosmology within the University of Cambridge. He had a slow-progressing form of amyotrophic lateral sclerosis (ALS) that gradually paralyzed him over decades.

Despite this disability, Stephen Hawking continued his research work and was able to communicate using a single cheek muscle attached to a speech-generating device. He died at his residence in Cambridge, England early in the morning of March 14. His family declined to reveal the cause of his death.
