Energy and Matter: General Relativity Explained

[Spar]

I heard that energy is a form of matter in general relativity. If it is true, could you tell me any book about this phenomenon, please?

I heard that energy is a form of matter in general relativity.

A. "I heard that" is not an acceptable source on PF. Where did you hear that?
B. It's not true. Therefore finding it in a book will be difficult.

From what you have written, I think you are having a problem forming the best question to find out what you want. You need to read a bit (lot?) about Relativity. This wiki link on Special relativity will take you to the relationship "E=mc²" which is the 'equivalence between energy and mass' you are referring to. When you have read that link and anything else you find you can cope with, get back to PF with specific questions, based on and quoting what you have read. Open ended Q and A really doesn't work very well at any level.

In any case your first bet is Special Relativity first. ('Rumors' out there can quote you anything ...)
