When people really understand the Big Bang and the whole sweep of the evolution of the universe, it will be clear that humans are fairly insignificant.
When I came to Berkeley, I met all these Nobel laureates and I got to know that they were regular people. They were very smart and very motivated and worked very hard, but they were still humans, whereas before they were kind of mythical creatures to me.
The discovery and investigation of life on other planets is likely to change many of our ideas about how life arose on the Earth and even what is life and its natural development.
I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.
For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas.
