Looking for good books on astrophysics, wormholes, relativity etc.

The Elegant Universe - Brian Greene (goes into string theory)

Hyperspace - Michio Kaku

Are the good ones I've read.

Also - Our Mathematical Universe - Max Tegmark, does a good job explaining some of the various multiverse theories out there.

All provide a solid base of classical physics and quantum mechanics before going into the more recent / theoretical stuff if I remember correctly.

ETA: I think Brian Greene has additional books which cover the different stuff you listed as well - he is a great author for this style IMO so you can probably just stick with him.

That is definitely a good one and most people's introduction - there have just been a lot of developments since then so some of it is out of date with more current research.

Also to the OP - "Astrophysics For People In a Hurry" may be the kind of thing you are looking for if not looking to dive deep into higher level dimensions, string theory and some of the more controversial theoretical topics

Ya I have that one - but it just doesn't go into reasons why and the potential fixes for the issues arising when they try and meld relativity with quantum mechanics - at least I don't really remember them doing that.

Honestly if you have that one, you really have relativity and all of that stuff covered for the most part.

That Michio Kaku has another one called "physics of the impossible" which covers some of the physics behind some of the ideas you see in science fiction. It is a pretty interesting read as well.

Greene's "Fabric of the Cosmos" is supposed to be the follow up to Elegant Universe - but I haven't read that one yet.

That one of Kaku's is more of a looking forward "what may be possible in the future" so its pretty cool. I got into reading these kinds of things a couple years ago and its incredible some of the stuff they bring up - can be both awe inspiring and depressing how insignificant everything seems at the same time.

I usually have two books going though, something like this and some fiction / easy reading type stuff because your brain will start to hurt and you can't process a ton of this in one sitting - at least I can't.
