It was Einstein’s dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein’s day hadn’t made enough progress in understanding the forces of nature for that to be a realistic goal.

Stephen Hawking

It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us

Stephen Hawking

It’s a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.

It’s clearly possible for a something to acquire higher intelligence than its ancestors: we evolved to be smarter than our ape-like ancestors, and Einstein was smarter than his parents.

Stephen Hawking

It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of forces.

Stephen Hawking

It’s time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

Stephen Hawking

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.
