One day when I was 8 years old, everyone was talking in hushed tones about a great scientist that had just died. His name was Albert Einstein.
In the future we'll be able to mentally contact anybody we want, see whatever image we want. And when we don't like it, we'll just turn it off.
In the future, I can imagine that we will genetically modify ourselves using the genes that have doubled our life span since we were chimpanzees.
A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.
Nations that use commodity capitalism as a stepping-stone to a mixed economy based on commodity/intellectual capitalism will most likely become rich.
If you could meet your grandkids as elderly citizens in the year 2100 … you would view them as being, basically, Greek gods… that's where we're headed.
You cannot create new science unless you realize where the old science leaves off and new science begins, and science fiction forces us to confront this.
I believe that science is the engine of prosperity, that if you look around at the wealth of civilization today, it's the wealth that comes from science.
You cannot create new science unless you realise where the old science leaves off and new science begins, and science fiction forces us to confront this.
If we do get a quantum theory of spacetime, it should answer some of the deepest philosophical questions that we have, like what happened before the big bang?

String theory is based on the simple idea that all the four forces of the universe: gravity, the electromagnetic force and the two nuclear forces, can be viewed, as music.
The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

We have learned more about the brain in the last fifteen years than in all prior human history, and the mind, once considered out of reach, is finally assuming center stage.
Today's clunky smart glasses will be replaced by smart contact lenses. We'll command them by voice, blinking, or even thinking, to interact visually in 3-D with the Internet.
Scientists who have dedicated their lives to building machines that think, feel that it's only a matter of time before some form of consciousness is captured in the laboratory.
You have to have a cultural ethic that allows for making mistakes. It cannot be that just because you make mistakes, you're out. You have to make mistakes in order to innovate.
Until computers and robots make quantum advances, they basically remain adding machines: capable only of doing things in which all the variables are controlled and predictable.
The river of time may fork into rivers, in which case you have a parallel reality and so then you can become a time traveler and not have to worry about causing a time paradox.
