The Universe Is A Symphony Of Strings,

Science Is Given Almost No Visibility In The Media. If A Martian Came Down To Earth And Watched Television, He'd Come To The Conclusion That All The World's Society Is Based On Britney Spears And Paris Hilton. He'd Be Amazed That Our Society Hasn't Collapsed.

What Do Oil Company Executives, Vampires And Nasa Bureaucrats All Have In Common? They Fear Solar Energy.

Scientific Revolutions, Almost By Definition, Defy Common Sense.

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.)

No One Knows When A Robot Will Approach Human Intelligence, But I Suspect It Will Be Late In The 21st Century. Will They Be Dangerous? Possibly. So I Suggest We Put A Chip In Their Brain To Shut Them Off If They Have Murderous Thoughts.
