Most sets of values would give rise to universes that, although they might be very beautiful, would contain no one able to wonder at that beauty.

The missing link in cosmology is the nature of dark matter and dark energy.

There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.

In Britain, like most of the developed world, stem-cell research is regarded as a great opportunity. America will be left behind if it doesn't change policy.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there are far too many equations to solve. I'm no better than anyone else at understanding what makes people tick, particularly women.

We are all different. There is no such thing as a standard or run-of-the-mill human being, but we share the same human spirit.

Some scientists think it may be possible to capture a wormhole and enlarge it many trillions of times to make it big enough for a human or even a spaceship to enter.

The human race may be the only intelligent beings in the galaxy.

Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do.

To confine our attention to terrestrial matters would be to limit the human spirit.

In my opinion, there is no aspect of reality beyond the reach of the human mind.
