Theoretical Physics

[Alberto_R2]

Hello, I'm thinking about starting to about the new theories about the universe and to understand better theoretical physics, and I'm wondering which books would be appropriate stating the fact that I've read the likes of Michio Kaku, Brian Greene and Sir Stephen Hawking. I want to gradually get a better idea on a technical level so any ideas from where to go if I read the authors mentioned?

Thanks in advanced.
