Questioning the Universe by Stephen Hawkings FYUGP AEC SCIENCE

Questioning the Universe is a TED Talk by the famous British Cosmologist and Scientist, Stephen Hawkings. It is divided into three parts - the first part deals with the origin and nature of the Universe, the second part deals with the possibility of extra terrestrial life or alien life and the third part deals with the future of human race. He gives details of The Big Bang Theory. Though there are SETI projects, ie, Search for Extra Terrestrial Intelligence, we do not have concrete ideas regarding alien life. Hawkings concludes the talk by saying that we have to Concentrate on the space instead of earth for a bright future as we are destroying the Earth in various ways.
