Quote: For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin. by author Stephen Hawking overlaid on photo of Stephen Hawking quote: For years, my early work with Roger Penrose seemed to be a disaster for science.

Quote: The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing? by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote

Quote: I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off.

Quote: Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote

Quote: With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code.

Longer Version/[Notes]:

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. By contrast, computers double their speed and memories every 18 months. There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.


Quote: The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C -- not much good for defrosting the pizza, let alone cooking it. by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote

Quote: I was born on January 8, 1942, exactly three hundred years after the death of Galileo. I estimate, however, that about two hundred thousand other babies were also born that day. I don't know whether any of them was later interested in astronomy. by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote

Quote: When we understand string theory, we will know how the universe began. It won't have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore. by author Stephen Hawking overlaid on photo of photo of author Stephen Hawking with quote
