A report from one of last Saturday’s events at the World Science Festival has string theorists Brian Greene and Shamit Kachru admitting that they’d be surprised to see experimental evidence for string theory in their lifetimes:
John Hockenberry, the panel’s moderator, asked Greene if he thought experimental evidence would come during his lifetime.
“I’d be surprised,” said Greene.
“And in your lifetime?” Hockenberry asked Kachru.
“…I’d be surprised,” conceded the young physicist reluctantly.
