Bruce Sterling spekuliert über die Zukunft des Geldes:

"Instead of credit ratings to acquire capital, credit records could become capital. If I'm superb at shopping, a super-user whose word is law for those who trust me for recommendations, how come I'm not paid to shop? Maybe Mr. A minds his p's and q's and never touches his capital--while Mr. B is a player who plunges into debt and escapes it repeatedly.
Instead of "socially responsible investment," we might be confronted with money that refuses to let itself be spent. Electronic funds might double check themselves against a blacklist before they move from one chip to another. Touch a terrorist bank account, and you might find yourself with not just a refusal of funds but also with instant taps on your phone and e-mail."

Michio Kaku erklärt verständlich für alle den aktuellen Stand der Wissenschaft in Sachen Zeitreise:

"Interestingly enough, Stephen Hawking once opposed the idea of time travel. He even claimed he had "empirical" evidence against it. If time travel existed, he said, then we would have been visited by tourists from the future. Since we see no tourists from the future, ergo: time travel is not possible. Because of the enormous amount of work done by theoretical physicists within the last 5 years or so, Hawking has since changed his mind, and now believes that time travel is possible (although not necessarily practical). (Furthermore, perhaps we are simply not very interesting to these tourists from the future."
