If The Theory Turns Out To Be

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.

There May Be Many Big Bangs That Happened At Various And Far-flung Locations, Each Creating Its Own Swelling, Spatial Expanse, Each Creating A Universe - Our Universe Being The Result Of Only One Of Those Big Bangs.

When You Drive Your Car, E = Mc2 Is At Work. As The Engine Burns Gasoline To Produce Energy In The Form Of Motion, It Does So By Converting Some Of The Gasoline's Mass Into Energy, In Accord With Einstein's Formula.

I’ve Spent Something Like 17 Years Working On A Theory For Which There Is Essentially No Direct Experimental Support.

The Central Idea Of String Theory Is Quite Straightforward. If You Examine Any Piece Of Matter Ever More Finely, At First You'll Find Molecules, Atoms, Sub-atomic Particles. Probe The Smaller Particles, You'll Find Something Else, A Tiny Vibrating Filament Of Energy, A Little Tiny Vibrating String.
