Stephen William Hawking, CH, CBE, FRS, FRSA is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. Hawking was the first to set forth a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He is a vigorous supporter of the many-worlds interpretation of quantum mechanics.

In The Past, There Was Active Discrimination Against Women In Science. That Has Now Gone, And Although There Are Residual Effects, These Are Not Enough To Account For The Small Numbers Of Women, Particularly In Mathematics And Physics.
I Have Wondered About Time All My Life.
Success In Creating Ai Would Be The Biggest Event In Human History. Unfortunately, It Might Also Be The Last, Unless We Learn How To Avoid The Risks.
Life On Earth Is At The Ever-increasing Risk Of Being Wiped Out By A Disaster, Such As Sudden Global Nuclear War, A Genetically Engineered Virus Or Other Dangers We Have Not Yet Thought Of.
Theoretical Physics Is One Of The Few Fields In Which Being Disabled Is No Handicap - It Is All In The Mind.
My Advice To Other Disabled People Would Be, Concentrate On Things Your Disability Doesn't Prevent You Doing Well, And Don't Regret The Things It Interferes With. Don't Be Disabled In Spirit As Well As Physically.
There Is No Physical Law Precluding Particles From Being Organised In Ways That Perform Even More Advanced Computations Than The Arrangements Of Particles In Human Brains.
Before 1915, Space And Time Were Thought Of As A Fixed Arena In Which Events Took Place, But Which Was Not Affected By What Happened In It. Space And Time Are Now Dynamic Quantities... Space And Time Not Only Affect But Are Also Affected By Everything That Happens In The Universe.

The Cyclic Universe Theory Predicts No Gravitational Waves From The Early Universe.
It's A Pity That Nobody Has Found An Exploding Black Hole. If They Had, I Would Have Won A Nobel Prize.
Work Gives You Meaning And Purpose And Life Is Empty Without It.
It Was Einstein's Dream To Discover The Grand Design Of The Universe, A Single Theory That Explains Everything. However, Physicists In Einstein's Day Hadn't Made Enough Progress In Understanding The Forces Of Nature For That To Be A Realistic Goal.
Exploration By Real People Inspires Us.
Only Black Holes Of Very Low Mass Would Emit A Significant Amount Of Radiation.
According To 'M' Theory, Ours Is Not The Only Universe. Instead, 'M' Theory Predicts That A Great Many Universes Were Created Out Of Nothing.
Cambridge Is One Of The Best Universities In The World, Especially In My Field.
If You Believe In Science, Like I Do, You Believe That There Are Certain Laws That Are Always Obeyed.
There Is Nothing Bigger Or Older Than The Universe.
Many Badly Needed Goals, Like Fusion And Cancer Cure, Would Be Achieved Much Sooner If We Invested More.
Up Until The 1920s, Everyone Thought The Universe Was Essentially Static And Unchanging In Time.
If I Had A Time Machine, I'd Visit Marilyn Monroe In Her Prime Or Drop In On Galileo As He Turned His Telescope To The Heavens.
My Father Was A Research Scientist In Tropical Medicine, So I Always Assumed I Would Be A Scientist, Too. I Felt That Medicine Was Too Vague And Inexact, So I Chose Physics.
We Are All Now Connected By The Internet, Like Neurons In A Giant Brain.
Before We Understand Science, It Is Natural To Believe That God Created The Universe.
To Confine Our Attention To Terrestrial Matters Would Be To Limit The Human Spirit.
Among Physicists, I'm Respected I Hope.
I Believe Everyone Should Have A Broad Picture Of How The Universe Operates And Our Place In It. It Is A Basic Human Desire. And It Also Puts Our Worries In Perspective.
