All my adult life people have been helping me.

Stephen Hawking

All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.

Stephen Hawking

All that my work has shown is that you don’t have to say that the way the universe began was the personal whim of God.

Stephen Hawking

Although almost every theoretical physicist agrees with my prediction that a black hole should glow like a hot body, it would be very difficult to verify experimentally because the temperature of a macroscopic black hole is so low.

Stephen Hawking

Although in principle we know the equations that govern the whole of biology, we have not been able to reduce the study of human behavior to a branch of applied mathematics.

Stephen Hawking

Although quantum mechanics has been around for nearly 70 years, it is still not generally understood or appreciated, even by those that use it to do calculations.

Stephen Hawking

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

Stephen Hawking

Among physicists, I’m respected I hope.
