...should have said something about her new dress"). Time travel allows us to pay for an experience once and then have it again and again at no additional charge, learning new lessons with each repetition. When we are busy having experiences--herding children, signing checks, battling traffic--the dark network is silent, but as soon as those experiences are over, the network is awakened, and we begin moving across the landscape of our history to see what we can learn--for free...

We may not heed the warnings that prospection provides, but at least we aren't surprised when we wake up with a hangover or when our waists and our inseams swap sizes. The dark network allows us to visit the future, but not just any future. When we contemplate futures that don't include us--Will the NASDAQ be up next week?

Such primitive triggers almost certainly afforded...

His dark blue eyes dart left and right in search of the familiar reassurance of his mother's face. She calls his name and makes soothing noises, but Daniel senses something unusual is happening. He sucks his fingers for comfort, but, finding no solace, his mouth crumples, his body stiffens, and he lets rip an almighty shriek of distress. Mom picks him up, reassures him, and two minutes later, a chortling and alert Daniel returns...
