The light of other days by Arthur C Clarke& Stephen Baxter

Its set about 30 years from now. A sort of Rupert Murdoch figure reveals his wormcam technology which allowsvisualsto travelby tiny wormholes so instant communications are allowed which lets his media group always be the first to the story. They can see anywhere on earthinstantly with this device and eventually realise that it can also see in time. So they start watching all the events in history...Jesus,Carthage etc etc

Am about halfway through now and so far it seems like a version of Issac Asimov's short story "the dead past" where scientists have a machine that sees thepast butuseit to see the present and become voyuers threatening the fabric of society. Everyone is peeping constantly on everyone else.

This story has similar implications andit is good reading so far. Also there is a sub plot that the main character a female reporterfamous for discovering a asteroid which will destroy earth in 500 years... How that affects the human condition on the planet is amusing as well. Oh yeah they called the asteroid "wormwood" LOL

Its a good book if you like sci fi like I do, Arthur C Clarke is one of the daddys of the genre and its a good book from him.
