Computer scientists at the University of Alberta have solved the ancient game of checkers: After 18-and-a-half years and sifting through 500 billion billion (a five followed by 20 zeroes) checkers positions, Dr. Jonathan Schaeffer and colleagues have built a checkers-playing computer program that cannot be beaten.

It’s generally believed time travel into the past is impossible. Only…nobody can quite figure out why it’s impossible. So just maybe, it isn’t. John Cramer’s experiment to see if it’s possible to detect an effect before a cause is going ahead: University of Washington physicist (and science-fiction author) John Cramer is moving forward with his …

The …
