Even If We Mortgage The Next 100

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.)

Cesium, Iodine From The Chernobyl Reactor Accident Went Around The World Many Times And Everyone On The Earth Has A Piece Of Chernobyl In Their Bodies, But It's Very Tiny - Too Small To Cause Much Damage.

It's Risky To Allow Radiation To Constantly Go Up Into The Atmosphere. The Main Criticism Of This Approach Of Entombing It Is That It Would Cost Too Much, Involve Too Many Resources And People. But Think Of The Cost Of Having All The Crops Impounded By The Government, All The Milk Being Thrown Into The River, People's Livelihoods Destroyed.

Language And Emotions Are Too Easily Misread. For Example, Laughing Can Mean Many Things: Laughing With You Or At You. Does That Laugh Reflect Joy, Anger, Or That S/he's About To Fire You? Too Many Jobs Require Complex Feelings, Pattern Recognition, Common Sense, And The Human Touch.

I'm A Physicist, And We Have Something Called Moore's Law, Which Says Computer Power Doubles Every 18 Months. So Every Christmas, We More Or Less Assume That Our Toys And Appliances Are More Or Less Twice As Powerful As The Previous Christmas.
