Sean McMullen is an Australian science fiction writer, whose first books were only published there, with Souls in the Great Machine being the first one available in the rest of the world. Apparantely it’s a rewrite of two earlier McMullen novels, Voices In The Light and Mirrorsun Rising, which were of course only available in Australia. In any event, Souls in the Great Machine is the first novel (or indeed anything) I’ve read of McMullen, after the local science fiction bookstore had it and its sequel, The Miocene Arrow available cheap. Because of good reviews in Locus and elsewhere I thought I’d take a gamble.

On the whole I think Souls in the Great Machine was worth the gamble, though I had some caveats. The writing isn’t always as smooth as you would like and the overall plot is a bit …episodic shall we say, which may of course be a result of it having started as two separate books. The most bothersome aspect of McMullen’s writing however is his sudden and rather frequent switch of viewpoints. Usually even with authors who like to jump from character to character you still get a good sense of who the heroes of their stories are, but with this book there are several perspective shifs which abandon the character you thought was the protagonist for someone else entirely. This feels a bit sloppy, but is more than made up for by the inventiveness McMullen displays in his depiction of the world of Souls in the Great Machine.

Time travel in Einstein’s Universe — J. Richard Gott

Time Travel in Einstein’s Universe

I have to say, Time Travel in Einstein’s Universe does exactly what it says on the tin, exploring the possibility and methods of timetravel in the universe as we know it since Einstein formulated his formulas about special and general relativity. In the process Gott manages to also explore some of the more exotic theories about our universe and how it came to be. It seems that science fiction writers got stiff competition from astrophysicists these days in dreaming up weird and wonderful posssible universes…

It’s this that I have a bit of a problem with here. Granted, this is of course a popular science book, written for thickies and ignoramuses like myself, but it seems to me that a lot of what Gott theorises here is put too strongly as the truth rather than as just a possibility, a theory. For example, at one point he is explaining how the universe might have used timetravel to come into existence, having a closed timeloop for an origin rather than a true origin, now safely in our past so that we can no longer use this timeloop ourselves. Now I’m sure this is all allowed by the maths, but is there any observable support for this theory? That is, can our measurements of the observable universe prove or disprove this theory? Because otherwise, what is the point?
