Hawking has given many lectures to the general public. Below are some of the more recent public lectures. Included with these lectures is a Glossary of some of the terms used.
Into a Black Hole (2008): Is it possible to fall in a black hole, and come out in another universe? Can you escape from a black hole once you fall inside? What have we discovered about black holes?
The Origin of the Universe (2005): Why are we here? Where did we come from? The answer generally given was that humans were of comparatively recent origin, because it must have been obvious, even at early times, that the human race was improving in knowledge and technology. So it can't have been around that long, or it would have progressed even more.
Godel and the End of Physics (2002): How far can we go in our search for understanding and knowledge? Will we ever find a complete form of the laws of nature - a set of rules that in principle at least enable us to predict the future to an arbitrary accuracy, knowing the state of the universe at one time? A qualitative understanding of the laws has been the aim of philosophers and scientists, from Aristotle onwards.
Space and Time Warps (1999): In science fiction, space and time warps are a commonplace. They are used for rapid journeys around the galaxy, or for travel through time. But today's science fiction, is often tomorrow's science fact. So what are the chances for space and time warps?
Does God Play Dice (1999): Can predict the future, or is it arbitrary and random? In ancient times, the world must have seemed pretty arbitrary. Disasters such as floods or diseases must have seemed to happen without warning or apparent reason. Primitive people attributed such natural phenomena, to a pantheon of gods and goddesses, who behaved in a capricious and whimsical way. There was no way to predict what they would do, and the only hope was to win favour by gifts or actions.
The Beginning of Time (1996): Has time itself a beginning, and will it have an end? All the evidence seems to indicate, that the universe has not existed forever, but that it had a beginning, about 15 billion years ago. This is probably the most remarkable discovery of modern cosmology. Yet it is now taken for granted. We are not yet certain whether the universe will have an end.
Life in the Universe (1996): Speculations about how life has developed in the universe, and in particular, the development of intelligent life.
