When I Get To Heaven I'm Gonna Find The Guy In Charge Of The Weather And Kick His Rear.

Thirty Years Ago I Was Diagnosed With Motor Neurone Disease, And Given Two And A Half Years To Live. I Have Always Wondered How They Could Be So Precise About The Half.

One Can Imagine That God Created The Universe At Literally Any Time In The Past. On The Other Hand, If The Universe Is Expanding, There May Be Physical Reasons Why There Had To Be A Beginning. One Could Imagine That God Created The Universe At The Instant Of The Big Bang, Or Even Afterwards In Just Such A Way As To Make It Look As Though There Had Been A Big Bang, But It Would Be Meaningless To Suppose That It Was Created Before The Big Bang. An Expanding Universe Does Not Preclude A Creator, But It Does Place Limits On When He Might Have Carried Out His Job!

The Idea That We Are Alone In The Universe Seems To Me Completely Implausible And Arrogant, Considering The Number Of Planets And Stars That We Know Exist, It's Extremely Unlikely That We Are The Only Form Of Evolved Life.

The More You Learn, The More You Know. The More You Know, The More You Forget. The More You Forget, The Less You Know. So Why Bother To Learn.

Unless Mankind Redesigns Itself By Changing Our Dna Through Altering Our Genetic Makeup, Computer-genera Ted Robots Will Take Over Our World.

It Is My View That The Simplest Explanation Is There Is No God. No One Created The Universe And No One Directs Our Fate. This Leads Me To A Profound Realization. There Is Probably No Heaven, And No Afterlife Either. We Have This One Life To Appreciate The Grand Design Of The Universe, And For That, I Am Extremely Grateful.

The Question Is: Is The Way The Universe Began Chosen By God For Reasons We Can't Understand, Or Was It Determined By A Law Of Science? I Believe The Second. If You Like, You Can Call The Laws Of Science 'god', But It Wouldn't Be A Personal God That You Could Meet, And Ask Questions.

Some Individuals Are Better Able Than Others To Draw The Right Conclusions About The World About Them And Act Accordingly. These Individuals Will Be More Likely To Survive And Reproduce So Their Pattern Of Behaviour And Thought Will Become Dominant

If It Were Only A Few Degrees, That Would Be Serious, But We Could Adapt To It. But The Danger Is The Warming Process Might Be Unstable And Run Away. We Could End Up Like Venus, Covered In Clouds And With The Surface Temperature Of 400 Degrees. It Could Be Too Late If We Wait Until The Bad Effects Of Warming Become Obvious. We Need Action Now To Reduce Emission Of Carbon Dioxide.

We Only Have To Look At Ourselves To See How Intelligent Life Might Develop Into Something We Wouldnt Want To Meet. I Imagine They Might Exist In Massive Ships, Having Used Up All The Resources From Their Home Planet. Such Advanced Aliens Would Perhaps Become Nomads, Looking To Conquer And Colonize Whatever Planets They Can Reach.

If We Can Avoid Disaster For The Next Two Centuries, Our Species Should Be Safe As We Spread Into Space. If We Are The Only Intellegent Beings In The Galaxy We Should Make Sure We Survive And Continue. . . . Our Only Chance Of Long-term Survival Is Not To Remain Inward Looking On Planet Earth But To Spread Out Into Space. We Have Made Remarkable Progress In The Last Hundred Years. But If We Want To Continue Beyond The Next Hundred Years, Our Future Is In Space.

The World Has Changed Far More In The Past 100 Years Than In Any Other Century In History. The Reason Is Not Political Or Economic But Technological-technologies That Flowed Directly From Advances In Basic Science. Clearly, No Scientist Better Represents Those Advances Than Albert Einstein: Time's Person Of The Century.

What I Have Learned From Life Is To Make The Most Of What You Have Got.

A Few Years Ago, The City Council Of Monza, Italy, Barred Pet Owners From Keeping Goldfish In Curved Bowls... Saying That It Is Cruel To Keep A Fish In A Bowl With Curved Sides Because, Gazing Out, The Fish Would Have A Distorted View Of Reality. But How Do We Know We Have The True, Undistorted Picture Of Reality?

Because There Is A Law Such As Gravity, The Universe Can And Will Create Itself From Nothing.

I Don't Have Much Positive To Say About Motor Neuron Disease, But It Taught Me Not To Pity Myself Because Others Were Worse Off, And To Get On With What I Still Could Do. I'm Happier Now Than Before I Developed The Condition.

If Time Travel Is Possible, Where Are The Tourists From The Future?

I Think Computer Viruses Should Count As Life.

Theology Is Unnecessary.

I Think My Dad [ Stephen Hawking] Would Have Been Pleased If I Had Turned Out A Scientist Because He Truly Believes That Is The Most Interesting Career Open To Anyone. But He Also Believes That You Have To Follow Your Own Path In Life And So He Certainly Wasn't Going To Push Me Toward Theoretical Physics When It Didn't Look Like I Was Going In That Direction Naturally.

Not Only That God Does Play Dice, But That He Sometimes Confuses Us By Throwing Them Where They Can't Be Seen.

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.

Hang In There, Retirement Is Only Thirty Years Away!

Science Is Beautiful When It Makes Simple Explanations Of Phenomena Or Connections Between Different Observations.

This Required Abandoning The Idea That There Is A Universal Quantity Called Time That All Clocks Measure. Instead, Everyone Would Have His Own Personal Time. The Clocks Of Two People Would Agree If They Were At Rest With Respect To Each Other But Not If They Were Moving. This Has Been Confirmed By A Number Of Experiments, Including One In Which An Extremely Accurate Timepiece Was Flown Around The World And Then Compared With One That Had Stayed In Place. If You Wanted To Live Longer, You Could Keep Flying To The East So The Speed Of The Plane Added To The Earth

We Are All Now Connected By The Internet, Like Neurons In A Giant Brain.

I Have Experimental Evidence That Time Travel Is Not Possible.

It Surprises Me How Disinterested We Are Today About Things Like Physics, Space, The Universe And Philosophy Of Our Existence, Our Purpose, Our Final Destination. Its A Crazy World Out There. Be Curious.

Succeed In Spite Of Management.

If There Really Is A Complete Unified Theory That Governs Everything, It Presumably Also Determines Your Actions. But It Does So In A Way That Is Impossible To Calculate For An Organism That Is As Complicated As A Human Being. The Reason We Say That Humans Have Free Will Is Because We Can't Predict What They Will Do.

I Think The Next [21st] Century Will Be The Century Of Complexity. We Have Already Discovered The Basic Laws That Govern Matter And Understand All The Normal Situations. We Don't Know How The Laws Fit Together, And What Happens Under Extreme Conditions. But I Expect We Will Find A Complete Unified Theory Sometime This Century. The Is No Limit To The Complexity That We Can Build Using Those Basic Laws.

Many People Do Not Like The Idea That Time Has A Beginning, Probably Because It Smacks Of Divine Intervention.

Science Does Not Deny Religion, It Just Offers A Simpler Alternative.

The Life We Have On Earth Must Have Spontaneously Generated Itself. It Must Therefore Be Possible For Life To Generate Spontaneously Elsewhere In The Universe.

Government Works Best Under The Glare Of Public Scrutiny. Absent Such Scrutiny, Abuses Occur.

There Is No Prescribed Route To Follow To Arrive At A New Idea. You Have To Make The Intuitive Leap.

Everyone Can Enjoy A Life Of Luxurious Leisure If The Machine-produced Wealth Is Shared, Or Most People Can End Up Miserably Poor If The Machine-owners Successfully Lobby Against Wealth Redistribution.

Any Physical Theory Is Always Provisional, In The Sense That It Is Only A Hypothesis: You Can Never Prove It.

Physics As We Know It Will Be Over In Six Months - Max Born

Nothing Is Fool-proof To A Sufficiently Talented Fool.

If The Total Energy Of The Universe Must Always Remain Zero, And It Costs Energy To Create A Body, How Can A Whole Universe Be Created From Nothing?

If It [the Universe] Was Expanding Fairly Slowly, The Force Of Gravity Would Cause It Eventually To Stop Expanding And Then To Start Contracting. However, If It Was Expanding At More Than A Certain Critical Rate, Gravity Would Never Be Strong Enough To Stop It, And The Universe Would Continue To Expand Forever.

Before We Understand Science, It Is Natural To Believe That God Created The Universe. But Now Science Offers A More Convincing Explanation.

Nothing Is Better Than Reading And Gaining More And More Knowledge.

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.

Time Travel Was Once Considered Scientific Heresy, And I Used To Avoid Talking About It For Fear Of Being Labelled A 'crank.'

Scientists Have Become The Bearers Of The Torch Of Discovery In Our Quest For Knowledge.

God Not Only Plays Dice, He Throws Them In The Corner Where You Can't See Them.

You Can't Regulate Every Lab In The World.

If What We Regard As Real Depends On Our Theory, How Can We Make Reality The Basis Of Our Philosophy? But We Cannot Distinguish What Is Real About The Universe Without A Theory. It Makes No Sense To Ask If It Corresponds To Reality, Because We Do Not Know What Reality Is Independent Of A Theory.

The Increase Of Disorder Or Entropy With Time Is One Example Of What Is Called An Arrow Of Time, Something That Distinguishes The Past From The Future, Giving A Direction To Time.

Money Is Not Everything. There's Master Card & Visa.

Although I Cannot Move, And I Have To Speak Through A Computer, In My Mind, I Am Free.

Not To Take This Web Of Dualities As A Sign We Are On The Right Track Would Be A Bit Like Believing That God Put Fossils Into The Rocks In Order To Mislead Darwin About The Evolution Of Life.

If The Government Is Covering Up Knowledge Of Aliens, They Are Doing A Better Job Of It Than They Do At Anything Else.

There Is No Prescribed Route To Follow To Arrive At A New Idea. You Have To Make The Intuitive Leap. But The Difference Is That Once You've Made The Intuitive Leap You Have To Justify It By Filling In The Intermediate Steps. N My Case, It Often Happens That I Have An Idea, But Then I Try To Fill In The Intermediate Steps And Find That They Don't Work, So I Have To Give It Up.

The Meaning In Life Is Not Out There But Inbetween Our Ears. In Many Ways This Makes Us The Lords Of Creation.

One Could Imagine Such Technology Outsmarting Financial Markets, Out-inventing Human Researchers, Out-manipulating Human Leaders, And Developing Weapons We Cannot Even Understand.

If Aliens Visit Us, The Outcome Would Be Much As When Columbus Landed In America, Which Didn't Turn Out Well For The Native Americans.

Maybe I'm Being A Bit Harsh On Philosophers, But They Have Not Been Very Kind To Me... I Have Been Variously Called Nominalist, An Instrumentalist, A Positivist, A Realist, And Several Other Ists. The Technique Seems Refutation By Denigration: If You Can Attach A Label To My Approach, You Don't Have To Say What Is Wrong With It... I Am Sure That Einstein, Heisenberg And Dirac Didn't Worry About Whether They Were Realists Or Instrumentalists.

If The Rate Of Expansion One Second After The Big Bang Had Been Smaller By Even One Part In A Hundred Thousand Million Million, It Would Have Recollapsed Before It Reached Its Present Size. On The Other Hand, If It Had Been Greater By A Part In A Million, The Universe Would Have Expanded Too Rapidly For Stars And Planets To Form.

We Should Seek The Greatest Value Of Our Action.

When I Hear Of Schrödinger's Cat, I Reach For My Pistol.

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. Theoretically, It Could Be Re-created On A Neural Network, But That Would Be Very Difficult, As It Would Require All One's Memories.

I Put A Lot Of Effort Into Writing 'a Briefer History' At A Time When I Was Critically Ill With Pneumonia Because I Think That It's Important For Scientists To Explain Their Work, Particularly In Cosmology. This Now Answers Many Questions Once Asked Of Religion.

One Can't Prove That God Doesn't Exist. But Science Makes God Unnecessary. The Laws Of Physics Can Explain The Universe Without The Need For A Creator.

The Lesson Of The Book Is That The Universe Is Governed By The Laws Of Science.

I Believe In The Possible. I Believe, Small Though We Are, Insignificant Though We May Be, We Can Reach A Full Understanding Of The Universe. You Were Right When You Said You Felt Small, Looking Up At All That Up There. We Are Very, Very Small, But We Are Profoundly Capable Of Very, Very Big Things.

We Live In The Most Probable Of All Possible Worlds.

Working With My Father [stephen Hawking ] Is A Great Thrill - He Has The Amazing Ability To Hold Enormous Amounts Of Information In His Head.

Never Put Off The Work Till Tomorrow What You Can Put Off Today.

I Would Rather Be Right Than Rigorous.

I Think Computer Viruses Should Count As Life ... I Think It Says Something About Human Nature That The Only Form Of Life We Have Created So Far Is Purely Destructive. We've Created Life In Our Own Image.

Why Are We Here? Where Do We Come From? Traditionally, These Are Questions For Philosophy, But Philosophy Is Dead.

The Concern Here Is That Financial Services Become A Kind Of Tech-led Wild West.

If I Have Questions About The Universe On My Mind When I Go To Bed, I Can't Turn Off. I Dream Equations All Night.

The Rate Of Progress Is So Rapid That What One Learns At School Or University Is Always A Bit Out Of Date. Only A Few People Can Keep Up With The Rapidly Advancing Frontier Of Knowledge, And They Have To Devote Their Whole Time To It And Specialize In A Small Area. The Rest Of The Population Has Little Idea Of The Advances That Are Being Made Or The Excitement They Are Generating.

Being Confined To A Wheelchair Doesn't Bother Me As My Mind Is Free To Roam The Universe, But It Felt Wonderful To Be Weightless.

It Matters If You Don't Just Give Up.

The Whole History Of Science Has Been The Gradual Realization That Events Do Not Happen In An Arbitrary Manner, But That They Reflect A Certain Underlying Order, Which May Or May Not Be Divinely Inspired.

Of Course It Is Possible That Ufo's Really Do Contain Aliens As Many People Believe, And The Government Is Hushing It Up

One Can't Predict The Weather More Than A Few Days In Advance.

It Would Be Very Difficult To Explain Why The Universe Should Have Begun In Just This Way, Except As The Act Of A God Who Intended To Create Beings Like Us.

I Want To Encourage Public Interest In Space. I Have Never Let My Condition Stop Me. You Only Live Once.

There Is Nothing Bigger Or Older Than The Universe.

Computers Double Their Performance Every Month.

If You Understand How The Universe Operates, You Control It In A Way.

We Don't Let Animals Suffer, So Why Humans?

A Theory Is A Good Theory If It Satisfies Two Requirements: It Must Accurately Describe A Large Class Of Observations On The Basis Of A Model That Contains Only A Few Arbitrary Elements, And It Must Make Definite Predictions About The Results Of Future Observations.

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.

There Are Plenty Of Dead Scientists I Admire, But I Can't Think Of Any Living Ones. This Is Probably Because It Is Only In Retrospect That One Can See Who Made The Important Contributions.

I Think [contacting An Alien Civilization] Would Be A Disaster. The Extraterrestrials Would Probably Be Far In Advance Of Us. The History Of Advanced Races Meeting More Primitive People On This Planet Is Not Very Happy, And They Were The Same Species. I Think We Should Keep Our Heads Low.

I Am Just A Child Who Has Never Grown Up. I Still Keep Asking These 'how' And 'why' Questions. Occasionally, I Find An Answer.

Our Population And Our Use Of The Finite Resources Of Planet Earth Are Growing Exponentially, Along With Our Technical Ability To Change The Environment For Good Or Ill. But Our Genetic Code Still Carries The Selfish And Aggressive Instincts That Were Of Survival Advantage In The Past. It Will Be Difficult Enough To Avoid Disaster In The Next Hundred Years, Let Alone The Next Thousand Or Million. Our Only Chance Of Long Term Survival, Is Not To Remain Inward Looking On Planet Earth, But To Spread Out Into Space.

The Idea Of 10 Dimensions Might Sound Exciting, But They Would Cause Real Problems If You Forget Where You Parked Your Car.

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.

Intelligence Is The Ability To Adapt To Change.

[question: Do You Feel That Scientists Correct Themselves As Often As They Should?] More Often Than Politicians, But Not As Often As They Should.

Gravity Is So Strong That Space Is Bent Round Onto Itself, Making It Rather Like The Surface Of The Earth. If One Keeps Traveling In A Certain Direction On The Surface Of The Earth, One Never Comes Up Against An Impassable Barrier Or Falls Over The Edge, But Eventually Comes Back To Where One Started.

My Goal Is Simple. It Is A Complete Understanding Of The Universe, Why It Is As It Is And Why It Exists At All.

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 Think We Have Solved The Mystery Of Creation. Maybe We Should Patent The Universe And Charge Everyone Royalties For Their Existence.

One Might Think This Means That Imaginary Numbers Are Just A Mathematical Game Having Nothing To Do With The Real World. From The Viewpoint Of Positivist Philosophy, However, One Cannot Determine What Is Real. All One Can Do Is Find Which Mathematical Models Describe The Universe We Live In. It Turns Out That A Mathematical Model Involving Imaginary Time Predicts Not Only Effects We Have Already Observed But Also Effects We Have Not Been Able To Measure Yet Nevertheless Believe In For Other Reasons. So What Is Real And What Is Imaginary? Is The Distinction Just In Our Minds?

Quiet People Have The Loudest Minds.

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.

What I Have Done Is To Show That It Is Possible For The Way The Universe Began To Be Determined By The Laws Of Science. In That Case, It Would Not Be Necessary To Appeal To God To Decide How The Universe Began. This Doesn't Prove That There Is No God, Only That God Is Not Necessary.

We See The Universe The Way It Is Because We Exist.

Please Join Me In Applauding The Esa - European Space Agency’s Historic Efforts With The Rosetta Mission And Landing A Spacecraft On Rotating Comet. It May Seem Like A Work Of Fiction, But It Is Very Real, Very Impressive, And Will Help Us To Further Uncover The Mysteries Surrounding The Formation Of The Solar System. They Made A Beautiful Short Film Using An Imaginary Landscape To Illustrate Today’s Historic Feat.

Some People Would Claim That Things Like Love, Joy And Beauty Belong To A Different Category From Science And Can't Be Described In Scientific Terms, But I Think They Can Now Be Explained By The Theory Of Evolution.

Theory Of Evolution

I Would Like Nuclear Fusion To Become A Practical Power Source. It Would Provide An Inexhaustible Supply Of Energy, Without Pollution Or Global Warming.

In Fact, If One Considers The Possible Constants And Laws That Could Have Emerged, The Odds Against A Universe That Produced Life Like Ours Are Immense.

I Think The Universe Was Spontaneously Created Out Of Nothing, According To The Laws Of Science. It Has No Beginning And No End.

Bodies Like The Earth Are Not Made To Move On Curved Orbits By A Force Called Gravity; Instead, They Follow The Nearest Thing To A Straight Path In A Curved Space, Which Is Called A Geodesic. A Geodesic Is The Shortest (or Longest) Path Between Two Nearby Points.

When The Going Gets Tough, The Tough Take A Coffee Break.

I Think The Human Race Doesn't Have A Future If We Don't Go Into Space. We Need To Expand Our Horizons Beyond Planet Earth If We Are To Have A Long-term Future. We Cannot Remain Looking Inward At Ourselves On A Small And Increasingly Polluted And Overcrowded Planet. We Need To Look Outward To The Wider Universe.

Science Is Not Only A Disciple Of Reason But, Also, One Of Romance And Passion.

In A Brief History Of Time I Used The Word "god" Like Einstein Did As A Shorthand For The Laws Of Physics. However, This Is Not What Most People Mean By God, So I Have Decided Not To Use The Term. The Laws Of Physics Can Explain The Universe Without The Need For A God.

You May See A Cup Of Tea Fall Off A Table And Break Into Pieces On The Floor... But You Will Never See The Cup Gather Itself Back Together And Jump Back On The Table. The Increase Of Disorder, Or Entropy, Is What Distinguishes The Past From The Future, Giving A Direction To Time.

It Is Not Clear That Intelligence Has Any Long-term Survival Value.

Mankind's Greatest Achievements Have Come About By Talking And Its Greatest Failures By Not Talking. It Doesn’t Have To Be Like This.

In Real Time, The Universe Has A Beginning And An End At Singularities That Form A Boundary To Space-time And At Which The Laws Of Science Break Down.

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.

Once I Wept For I Had No Shoes. Then I Met A Man With No Feet, So I Took His Shoes. I Mean, It Wasn't As If He Was Going To Need Them.

One Can See From Space How The Human Race Has Changed The Earth. Nearly All Of The Available Land Has Been Cleared Of Forest And Is Now Used For Agriculture Or Urban Development. The Polar Icecaps Are Shrinking And The Desert Areas Are Increasing. At Night, The Earth Is No Longer Dark, But Large Areas Are Lit Up. All Of This Is Evidence That Human Exploitation Of The Planet Is Reaching A Critical Limit. But Human Demands And Expectations Are Ever-increasing. We Cannot Continue To Pollute The Atmosphere, Poison The Ocean And Exhaust The Land. There Isn't Any More Available.

The Moment You Understand The Whole Universe, Is The Moment You Slightly Begin To Understand The Way God's Mind Works

As We Shall See, The Concept Of Time Has No Meaning Before The Beginning Of The Universe. This Was First Pointed Out By St. Augustine. When Asked: What Did God Do Before He Created The Universe? Augustine Didn't Reply: He Was Preparing Hell For People Who Asked Such Questions. Instead, He Said That Time Was A Property Of The Universe That God Created, And That Time Did Not Exist Before The Beginning Of The Universe.

The Human Capacity For Guilt Is Such That People Can Always Find Ways To Blame Themselves

There Ought To Be Something Very Special About The Boundary Conditions Of The Universe And What Can Be More Special Than That There Is No Boundary?

Why Does The Universe Go To All The Bother Of Existing?

The Human Failing I Would Most Like To Correct Is Aggression. It May Have Had Survival Advantage In Caveman Days, To Get More Food, Territory Or A Partner With Whom To Reproduce, But Now It Threatens To Destroy Us All.

If Human Life Were Long Enough To Find The Ultimate Theory, Everything Would Have Been Solved By Previous Generations. Nothing Would Be Left To Be Discovered.

What I Meant By 'we Would Know The Mind Of God' Is, We Would Know Everything That God Would Know, If There Were A God. Which There Isn't. I'm An Atheist.

Obviously, Because Of My Disability, I Need Assistance. But I Have Always Tried To Overcome The Limitations Of My Condition And Lead As Full A Life As Possible. I Have Traveled The World, From The Antarctic To Zero Gravity.

Real Science Can Be Far Stranger Than Science Fiction And Much More Satisfying.

I Don't Think The Human Race Will Survive The Next Thousand Years, Unless We Spread Into Space.

I Do Not Believe In A Personal God.
