Really?

From the man who wrote the ground breaking A Brief History of Time, Stephen Hawking has achieved an acclaimed status all around the world. But his new ideas are really puzzling me. He firmly believes in the existance of extra terrestrial life, which is understandable. There's life here, so why not in other places? But he goes as far as to say to stay away from these E.T.'s because they, "exist in massive ships ... having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.” If this genius is worried about it, then maybe I should start to wear a tin foil hat. With all this aside, this man is an amazing example of suriviving the odds and never giving up. With the control of most of his body lost, he communicates using his cheek and an autocomplete system which puts together sentences and words for him. Suffering from amyotrophic lateral sclerosis(ALS) whose average life expectancy after diagnosis is 10 years, this man has made it to more than 40.
