No Matter How Hard You Try To

String Theory Has The Potential To Show That All Of The Wondrous Happenings In The Universe - From The Frantic Dance Of Subatomic Quarks To The Stately Waltz Of Orbiting Binary Stars; From The Primordial Fireball Of The Big Bang To The Majestic Swirl Of Heavenly Galaxies - Are Reflections Of One, Grand Physical Principle, One Master Equation.

I Wouldn't Say That The Fabric Of The Cosmos Is A Book On Cosmology. Cosmology Certainly Plays A Big Part, But The Major Theme Is Our Ever-evolving Understanding Of Space And Time, And What It All Means For Our Sense Of Reality.

String Theory Envisions A Multiverse In Which Our Universe Is One Slice Of Bread In A Big Cosmic Loaf. The Other Slices Would Be Displaced From Ours In Some Extra Dimension Of Space.

I Can Assure You That No String Theorist Would Be Interested In Working On String Theory If It Were Somehow Permanently Beyond Testability. That Would No Longer Be Doing Science.
