Brian Greene Quotes

Time Allows Change To Take Place And The Very Evolution Of The Universe Is What Requires Some Conception Of Time. Mathematically Can We Write Down A Universe That Doesn't Have Time? Sure. Do We Think That Would Be Realised In The Larger Reality That Is Out There? None Of Us Take That Possibility Seriously.

But If You Think About A Practical Implication Of Enriching Your Life And Giving You A Sense Of Being Part Of A Larger Cosmos And Possibly Being Able To Use This [gravitational Waves] As A Tool In The Future Maybe To Listen Not Just To Black Holes Colliding, But Maybe Listen To The Big Bang Itself, Those Kind Of Applications May Happen In The Not Too Distant Future.

General Relativity Is In The Old Newtonian Framework Where You Predict What Will Happen, Not The Probability Of What Will Happen. And Putting Together The Probabilities Of Quantum Mechanics With The Certainty Of General Relativity, That's Been The Big Challenge And That's Why We Have Been Excited About String Theory, As It's One Of The Only Approaches That Can Put It Together.

So Many Galaxies, So Many Planets Out There In The Universe Circling So Many Stars... It Just Feels Like There's A Very Good Chance That There Is Another Earth-like Planet Out There That Is Able To Support Some Kind Of Life Similar To What We're Familiar With.

I Enjoy Reading Blogs, But Am Not Interested In Having My Spurious Thoughts Out There.

When I Give This Talk To A Physics Audience, I Remove The Quotes From My 'theorem'.

Evidence In Support Of General Relativity Came Quickly. Astronomers Had Long Known That Mercury’s Orbital Motion Around The Sun Deviated Slightly From What Newton’s Mathematics Predicted. In 1915, Einstein Used His New Equations To Recalculate Mercury’s Trajectory And Was Able To Explain The Discrepancy, A Realization He Later Described To His Colleague Adrian Fokker As So Thrilling That For Some Hours It Gave Him Heart Palpitations.

How Can A Speck Of A Universe Be Physically Identical To The Great Expanse We View In The Heavens Above?

Relativity Challenges Your Basic Intuitions That You've Built Up From Everyday Experience. It Says Your Experience Of Time Is Not What You Think It Is, That Time Is Malleable. Your Experience Of Space Is Not What You Think It Is; It Can Stretch And Shrink.

Oftentimes, If You're Talking To A Seasoned Interviewer Who Asks You A Question, They May Do A Follow-up If They Didn't Quite Get It. It's Rare That They'll Do A Third Or Fourth Or Fifth Or Sixth Follow-up, Because There's An Implicit, Agreed-upon Decorum That They Move On. Kids Don't Necessarily Move On If They Don't Get It.

For Most People, The Major Hurdle In Grasping Modern Insights Into The Nature Of The Universe Is That These Developments Are Usually Phrased Using Mathematics.

Falsifiability For A Theory Is Great, But A Theory Can Still Be Respectable Even If It Is Not Falsifiable, As Long As It Is Verifiable.
