How much of Angels and Demons is actually true?

Its a book, that never made me think of anything else than the contents of the book and keep me in full concentration. Thats the skill of Dan brown to attract readers, and he din make it to accept his writings rather to enjoy reading, i believe thats Dan brown style.

History part is 100% true and about CERN i do think its equally true as there are scientist who are creating anti matter may be its made dont know its mystery lets see when they unfold it

I have read this book, quite a long times ago. As far as I can remember, It's worth reading. Once you start reading it, trust me, you don't want to put it down. About its authenticity is concerned, i think it's based on fiction work. That means, it's not true, even Mr Brown himself would admit that. Bottomline: The Author's intention to write on such subject is to gain madia attiontion. I like Dan Brown.

I am not 100% sure but I did love that book! Its was soo good! But one thing I do know is that they have created antimatter. Not near as much as they did in the book but a very small amount. I wonder if the movie will do the book justice?
