It's a book review -- doesn't really explain what the physicist is arguing in any meaningful sense.
- jamesbritt 17y ago"It's a book review -- doesn't really explain what the physicist is arguing in any meaningful sense." Indeed, the review ends with this: "Mr Vedral makes a persuasive argument for a third option: information can be created out of nothing." That's a remarkable claim, and the review says zip about how it is presented. It seems that it would also be the key concept of the book, making this a pretty lame review.
- Avshalom 17y agoWell it's not really remarkable at all, the argument is basically that information and entropy are mathematically equivalent and so information like entropy spontaneously increases.
- frisco 17y agoInformation and entropy are absolutely not equivalent; entropy describes the upper bound on information content, but says little about the actual information contained in a coding. The statement that information is spontaeously created isn't based in any physics I know of.
- Qz 17y agoHow does the (conventional) big bang theory fit into that? At first glance it seems like valid evidence for spontaneous creation of information.
