Now others at [Denver University] seem to be paying attention. "Can you imagine if we really succeed, if we get twenty students into this laboratory to do physics experiments?" says Hill excitedly. "Putting them into a nuclear control room and letting them do things and destroy things and not letting them get hurt? Think of what this means. Imagine how powerful this can be for education." But not everyone was thrilled when the story hit the online newspaper Inside Higher Ed last year. "Second Life isn't stable enough to test something that important," one commenter wrote. "Why not make a program that will actually simulate that properly? Second Life doesn't even stand up to normal 'game' quality. It can't even properly simulate a car."
