I Agree, Along With Carl Sagan, That

It Would Take A Civilization Far More Advanced Than Ours, Unbelievably Advanced, To Begin To Manipulate Negative Energy To Create Gateways To The Past. But If You Could Obtain Large Quantities Of Negative Energy-and That's A Big "if" - Then You Could Create A Time Machine That Apparently Obeys Einstein's Equation And Perhaps The Laws Of Quantum Theory.

The Best Theory Comes From String Theory, Which States That Dark Matter Is Nothing But A Higher Vibration Of The String. We Are, In Some Sense, The Lowest Octave Of A Vibrating String.

...the Laws Of Physics, Carefully Constructed After Thousands Of Years Of Experimentation, Are Nothing But The Laws Of Harmony One Can Write Down For Strings And Membranes. The Laws Of Chemistry Are The Melodies That One Can Play On These Strings. The Universe Is A Symphony Of Strings. And The "mind Of God," Which Einstein Wrote Eloquently About, Is Cosmic Music Resonating Throughout Hyperspace.

I Think A Colony In Space Will Take Much Longer Than Sci Fiction Writers Think. It Costs $10,000 To Put A Pound Of Anything Into Near Earth Orbit. That Is Your Weight In Gold. It Costs About $100,000 A Pound To Put You On The Moon. And It Costs $1,000,000 A Pound To Put You On Mars.

I Hope We Find Evidence Of Dark Matter In The Lab And In Outer Space. This Would Go A Long Way To Proving The Correctness Of String Theory, Which Is What I Do For A Living. That Is My Day Job. So String Theory Is A Potentially Experimentally Verifiable Theory.
