Greg Egan has recently released another novel, Dichronauts, which features another universe where the laws of physics are changed due to a sign change. (The first one is the Clockwork Rocket trilogy.)
Greg Egan is the only sci-fi author in my adult life who makes me think "I like this, but I'm not smart enough to really understand it." Feel free to take that as a recommendation either for or against. :)
I recently had an existential crisis reading an Egan book where a brain modification allows people to control the collapse of quantum waveforms and therefore the protagonist can "smear" into infinite possibilities and then "collapse" to the one where the desired outcome occurs. Do we already exist across an infinite number of dimensions and we are just limited by our ability to comprehend a single possibility? it's a fun thought.
So far, Incandescence is the toughest of his novels that I've read, and the main world is an extreme and beautiful conception where the ambient forces are all peculiar and the inhabitants are figuring out their cosmology as the novel goes on.
That said, I really could have used more diagrams while I was reading. I only found out after finishing that Egan has a whole bunch of Java applets on his website explaining the experiments that the main characters in the novel carry out, and why they give the results they do.
Quarantine it's a full novel. I feel like minded and the Egan books hit upon so many of the things I dream about. This author along with William Gibson and Neal Stephenson really resonate with a lot of the cutting edge concepts we deal with. I had no idea Egan was a programmer but it's apparent he is a genius reading his books so it fits.
I am madly in love with this mans writing, but MAN was that a tough read. With clockwork rocket (and the 5D sequences in Diaspora) I had to take some time with pen and paper to understand what he was saying, but Dichronauts takes this to another level entirely. I'm not sure I'll ever fully grok this one...
His more far-out books are fully recommended though if you want your mind blown with some exotics physics..!
