the book is free on this website
http://www.sidis.net/ANIMContents.htm you have to click on chapter to get the text and the cosomolgy nature of it seem a bit daughting but he uses mainly philosophy and reasoning rather then flashy meaingless mathematics and argument of beauti.
on nothing exsist it highly unlogical because if nothing exsist then something exsist and that nothing but nothing is not something theirfore it cant exsist which the nothing paradox it more sensable to say that something exsist i.e. an infinte universe and quantum mechaincs is infintly more likely.
p.s. any body wondering how william sidis became so smart it is explained in his farther book philistine and genius which is also free and online on this website
http://www.sidis.net/philistine_and_genius_menu.htm were he argue that intelligence is being replaced for a barbaric society where thinking is looked down on and explained why most people are morons that can barley read at 10 years where his son could read and write at age 2. i urge reader of this text to read both book because if really want to find the theory of everything you need some capacity for intelligence and logical reasoning and understanding.
