We Have The Media, Which Is Such

However, One New Theory Says That Dark Matter May Be Ordinary Matter In A Parallel Universe. If A Galaxy Is Hovering Above In Another Dimension, We Would Not Be Able To See It. It Would Be Invisible, Yet We Would Feel Its Gravity. Hence, It Might Explain Dark Matter.

Until Computers And Robots Make Quantum Advances, They Basically Remain Adding Machines: Capable Only Of Doing Things In Which All The Variables Are Controlled And Predictable. Robots Are Bad At Pattern Recognition And Certainly At Common Sense. That's Why Computers Can Beat Humans In Chess But Can't Have Even A Basic Conversation With A Six-year-old.

Physicists Often Quote From T. H. White's Epic Novel The Once And Future King, Where A Society Of Ants Declares, "everything Not Forbidden Is Compulsory." In Other Words, If There Isn't A Basic Principle Of Physics Forbidding Time Travel, Then Time Travel Is Necessarily A Physical Possibility. (the Reason For This Is The Uncertainty Principle. Unless Something Is Forbidden, Quantum Effects And Fluctuations Will Eventually Make It Possible If We Wait Long Enough. Thus, Unless There Is A Law Forbidding It, It Will Eventually Occur.)

Once Again, My Colleague Stephen Hawking Has Upset The Apple Cart. The Event Horizon Surrounding A Black Hole Was Once Though To Be An Imaginary Sphere. But Recent Theories Indicate That It May Actually Be Physical, Maybe Even A Sphere Of Fire. But I Don't Trust Any Of These Calculations Until We Have A Full-blown String Theory Calculation, Since Einstein's Theory By Itself Is Incomplete.

String Theory Is Based On The Simple Idea That All The Four Forces Of The Universe: Gravity, The Electromagnetic Force And The Two Nuclear Forces, Can Be Viewed, As Music.
